    On site landfill leachate treatment: investigations into economical and environmental sustainable systmes for Northern Ireland2017In: Ebook: Proceedings of 11th European Waste Water Management Conference, 2017Conference paper (Other (popular science, discussion, etc.))
    Abstract [en]

    This paper presents the potential for the Swedish Laqua system to be used as a sustainable method for on-site landfill leachate management in Northern Ireland, specifically the potential to use locally sourced filter materials from Northern Ireland as part of the filter system. Four carbon containing ashes and four types of peat were tested over a 24 hours period by a shaking test with untreated landfill leachate. Considering the results of this screening test, and the economical and sustainable supply of filter materials, one combination of ash and peat was selected to be column tested. Column testing with artificial leachate containing 7 organic pollutants (3 PAHs and 4 PCBs) and 9 inorganic pollutants showed that locally sourced filter materials effectively removed both organic and inorganic pollutants. A subsequent column test with landfill leachate for 13 weeks demonstrated it was feasible to apply the Laqua system with economical locally sourced filter materials.

    Can wetlands reduce humic substances in forested streams: combining two approaches to characterize efficiency2018In: Book of abstracts: Linnaeus ECO-TECH '18, 2018Chapter in book (Other academic)
    Abstract [en]

    Establishing statistical significance in assessing wetland performance can be quite challenging when reduction in the monitored substance is very small and temporarily variable. Assessing colour changes associated with humic substances is such a situation. One of the most important parameters of any evaluation of wetland treatment performances is the retention time of the water before it exit the wetland. This can be theoretically estimated, but even better measured directly with the help of a tracing agent. In this research, the approach is based on the simultaneously assessment of hydraulic retention time using conservative tracing (Rhodamine WT) and a mass balance based removal efficiency assessment (regression slope of the summation mass-in vs. summation mass-out).

    A new spectrophotometric method for improved indirect measurement of low levels of vitellogenin using malachite green2012In: International Journal of Environmental Analytical Chemistry, ISSN 0306-7319, E-ISSN 1029-0397, Vol. 92, no 7, p. 894-908Article in journal (Refereed)
    Abstract [en]

    Vitellogenin (VTG) is a well-known biomarker for endocrine disruption and the measurement of alkali-labile protein bound phosphate (ALP) has been used as an indirect quantification method for VTG in fish, clam and mussel. One limitation of the ALP method has been the insufficient detection limit but with the method presented here this obstacle has been overcome, enabling measurement in fish species with very low background levels and hence a wider usage of ALP measurements in the future. In a previous publication, relying on spectrophotometric measurement with molybdate, we presented an improved protocol for ALP measurement in fish plasma. The sample preparation in that paper has here been combined with an improved spectrophotometric determination using malachite green as colour reagent. The spectrophotometric measurement was optimised with respect to acidity and reagent concentration. The validated method has a detection limit of 0.3?µg? ?ml?1 plasma, which is 10 times lower than previous spectrophotometric methods using molybdate reagent, and an intra-assay variation of 7%. The new method was used for screening of endocrine effects by placing juvenile rainbow trout at three locations along the Vallkärra brook, Lund Sweden, which receives leachate water from a nearby covered landfill. In comparison with reference fish, ALP was significantly higher (66%) at the 99% confidence level in fish placed close to the landfill. ALP was also significantly higher (33%) at the 95% confidence level in fish from the group placed further downstream. Fish placed in a brook branch not receiving leachate were unaffected. The low levels of ALP in reference fish (5.5?±?0.7 SD ?µg/ml plasma) could not have been quantified with such precision with another method for ALP measurement. The indirect quantification of VTG as ALP is a more economic alternative compared to quantification with immunological methods.

    Improved spectrophotometric vitellogenin determination via alkali-labile phosphate in fish plasma: a cost effective approach for assessment of endocrine2009In: International Journal of Environmental Analytical Chemistry, ISSN 0306-7319, E-ISSN 1029-0397, Vol. 89, no 14, p. 1023-1042Article in journal (Refereed)
    Abstract [en]

    Vitellogenin (VTG) is a well known protein biomarker for exposure to environmental estrogens and possible endocrine disruption in fish. VTG is very dominant in plasma after the onset of vitellogenesis and the protein is heavily phosphorylated. This enables indirect quantification through measurement of alkali-labile protein bound phosphate (ALP) as an alternative to the more expensive enzyme linked immunosorbent assay. Good correlation has previously been shown between ALP and actual VTG levels but little effort has been made to investigate the method in an analytical way e.g., to assure the origin of the measured phosphate. During this method development care has been taken to rule out non-VTG sources of phosphate such as phospholipids and free phosphate in the blood plasma. Sample preparation has been simplified and unnecessary steps have been omitted. The common spectrophotometric measurement for ALP involves measurement at two wavelengths and calculation of corrected absorbance values. With a quick phase separation step the spectrophotometric phosphate determination using molybdic acid and ascorbic acid has been improved and all matrix interference has been eliminated. The final ALP method presented here has a detection limit of 3.2 µg PO43-/ml plasma which is six times lower than similar methods and it also has less variability. A high sample throughput in comparison to previous ALP methods is possible after scaling down sample and reagent volumes to fit in a 96 well microtiter plate. The cost for buying all chemicals and plastic consumer goods for setting up the indirect protocol for the analysis of 1000 samples is only circa 350 euro. This is only 1% of the material cost for buying commercially available test kit for direct quantification of VTG in the same number of samples. The ALP method should thus be of interest also for applied scientists outside advanced research laboratories.

    Column studies aiming at identification of suitable filter materials for pollutant removal from landfill leachate2008In: International Journal of Environment and Waste Management, ISSN 1478-9876, E-ISSN 1478-9868, Vol. 2, no 6, p. 506-525Article in journal (Refereed)
    Abstract [en]

    Landfill leachate contains a complex mixture of inorganic and organic pollutants, which need to be removed before they pollute the environment. Different filter media (peat mixed with either carbon-containing ash, polyurethane waste, or wood pellets) were investigated with respect to their possibility to simultaneously and at low initial concentrations remove metals, polar and non-polar organic compounds. The mixture of peat and carbon-containing ash was found to be the best medium. Reduction in leachate of phenolic substances was 96%, of PBDEs was over 98%, of DOC 40% and of important metals as Cu, Pb and Sn 60%, 90% and 93%, respectively.

    A case study of municipal solid waste in Nepal compared to the situation in the European Union and Sweden2010In: Proceedings Linnaeus ECO-TECH´10, Kalmar,  Sweden, Nov 22-24, 2010, 2010, p. 429-438Conference paper (Refereed)
    Abstract [en]

    Nepal, situated in the Himalayan belt has a rapidly growing population together with high

    urbanisation rate. These factors are currently causing problems connected to municipal solid

    waste (MSW). E.g. leakage of hazardous substances to soil and surrounding aquatic systems,

    spread of odour and naturally unfamiliar materials to natural biotopes, all of which generate

    environmental damage and health problems. There are certain differences in waste generation

    and waste composition between urban areas of Nepal. In order to retrieve a broad picture of

    the current waste management situation, three population differentiated municipalities in

    different areas of the country were investigated. Studies of the MSW regarding composition

    and generation were conducted. Moreover, waste management in Nepal was compared with

    the basic waste management in the European Union (EU) and Sweden. Landfill sites (LFS) in

    Ghorahi Municipality, Pokhara Sub-metropolitan City and Kathmandu Metropolitan City

    were studied. Our studies show differences in waste composition, generation and management

    between the three locations. The differences are somewhat interconnected with population

    size and tourism. Cities with higher population and more tourism tend to have a higher

    generation and more diverse MSW. Nevertheless, the urban areas of Nepal are very much in

    need of a more structured waste management system, a system more alike the waste

    management of EU. Apart from structural problems, there are attitude and behavioural issues

    that needs to be dealt with. Further studies regarding social patterns, attitude and behaviour,

    as well as the economic flow of MSW, needs to be conducted in order to retrieve an even

    broader picture and understand important underlying issues.

    Adequate sampling, an important step towards reiable decisions based on analytical results2010In: Proceedings: Linnaeus ECO-TECH´10, Kalmar,  Sweden, Nov 22-24, 2010, 2010, p. 16-23Conference paper (Refereed)
    Abstract [en]

    The efforts spent on judgments of how to perform sampling are often small compared to other

    steps in the analytical procedure. As a result decisions may be based on irrelevant results. If

    the sampling is intended to provide information how to reduce and control environmental

    pollution, it is important to design the sampling strategy according to scientific principles.

    Sampling will be discussed in relation to determinations of organic as well as inorganic

    species in different types of polluted matrices, .e.g. water, sediments and air. Examples will

    be taken from our own research projects about treatment processes for contaminated

    matrices.. Accurate sampling involves a basic planning including objectives, cost

    effectiveness versus the budget, variability of contamination leading to statistical

    considerations, site accessibility and robustness of the used devices. A strategy for the

    sampling, often in a form of a scheme, is needed. The Laqua Protocol developed within our

    research projects will be presented. This protocol is flexible and dynamic and can be altered

    and optimized based on the demands at the individual sampling site. Sampling of complicated

    matrices often creates problems with interfering agents and breakdown of unstable analytes.

    In this type of samples the concentrations of analytes are generally several orders of

    magnitudes lower than the concentrations of major constituents in the sample. Accordingly

    the advantages of an early work-up, preferably in connection with a sampling procedure, is

    paid especially attention

    Biomass from wetlands and other valuable conservation areas as substrate for industrial biotechnology2016In: The Ninth International Conference on the Establishment of Cooperation between Companies and Institutions in the Nordic Countries, the Baltic Sea Region, and the World, 2016Conference paper (Refereed)
    Abstract [en]

    Biomass  from  wetlands  has  historically  been  an  important  resource,  but  today  it  is  difficult  to  take advantage  of  this  biomass,  besides  being  used  as  feed  on  the  farm.  A  very  important  goal  is  to  find rational  and  economical  viable  way  to  make  biogas  from  wetland  biomass,  including  biomass  from other   conservation   worthy   areas   of   high   biodiversity,   such   as   roadsides   harvested   frequently. Moreover,  the  residues  from  biogas  process  used  as  bio-fertilizer  to  the  fields,  so  that  nitrogen  and phosphorus is returned to the farm land. The biomass can be used for the production of biogas or for extracting valuable chemicals in bio refineries. These valuable chemicals may be potentially useful for making future plastic materials, i.e. bio plastics. Major focus will be on biogas technology, and above all, methods for the pretreatment of recalcitrant substrates such as biomass containing high levels of lignocelluloses, i.e., to make the material available to the biogas-producing bacteria. The work is based on  an  involvement  of  research  in  the  areas  of  environmental  engineering  and  landscape  science  and includes studies of biodiversity and water treatment function of the landscape.  Finally, it is important to stress that mowing of wet meadows mostly will result in a better capacity of such meadows to retain nutrients from water passing through them. Wetland with wet meadows and similar vegetation types will be more efficient in cleaning water and thereby fight eutrophication in the recipient. Summing up, the  main  advantages  using  harvest  hay  (mowing)  from  wet  meadows  and  roadside  meadows  as substrate for biotechnical industry are:

    •Raw material for bio plastics

    •Cheap and easy handled fertilizers to agriculture

    •Important for biodiversity

    •Better function of wetlands as nutrient traps fighting eutrophication of the sea

    Artemia salina as test organism for assessment of acute toxicity of leachate water from landfills2005In: Environmental Monitoring & Assessment, ISSN 0167-6369, E-ISSN 1573-2959, Vol. 102, no 1-3, p. 309-321Article in journal (Refereed)
    Abstract [en]

    Artemia salina has, for the first time, been used as test organism for acute toxicity of leachate water from three landfills (the municipal landfills at Kristianstad, Sweden and Siauliai, Lithuania, and an industrial landfill at Stena Fragmenting AB, Halmstad, as well as for leachate from Kristianstad treated in different ways in a pilot plan). Artemia can tolerate the high concentrations of chloride ions found in such waters. Large differences in toxicities were found, the leachate from Siauliai being the most toxic one. To increase the selectivity in the measurements, a fractionation was done by using ion exchange to separate ammonium/ammonia and metal ions from the leachate, and activated carbon adsorbents for organic pollutants. The influence of some metals and phenol compounds on the toxicity was investigated separately. It was found that most of the toxicity emanated from the ammonium/ ammonia components in the leachate. However, there was also a significant contribution from organic pollutants, other than phenol compounds, since separate experiments had in this latter case indicated negligible impact. The concentrations of metals were at a level, shown by separate experiments, where only small contribution to the toxicity could be expected.

    Evaluation of filter material for treatment of different types of wastewater2011In: Journal of Environmental Protection, ISSN 2152-2197, E-ISSN 2152-2219, Vol. 2, no 7, p. 888-894Article in journal (Refereed)
    Abstract [en]

    This paper presents an evaluation of the suitability of a mixed absorbent based on peat and carbon-containing ash for treatment of wastewaters, such as wastewater from professional car washes, landfill leachate and stormwater. This mixture is very attractive, since it is a low-cost material which has a capability to simultaneously remove inorganic as well as organic pollutants. Since any filter material eventually needs to be replaced either due to saturation of pollutants or reduced infiltration capacity, it is important that the residual can be handled at low cost and that the environment will be not impaired. The tested mixture, used in filter beds, showed low leaching values and high simultaneous removal efficiency of metals as Cu, Cd and Pb, non-polar organic compounds such as PCBs. Polar organic compounds as phenols were also efficiently removed by microbial and/or chemical degradation in the studied treatment plants with the filter bed acted as a biofilter. Filter material used for three years in a full-scale plant for leachate treatment and four years in treatment plants for wastewater from car washes, had sufficiently high energy content indicating that energy recovery is a good alternative for handling after its usage. Results show that the presented filter material is excellent for both small scale applications (e.g. treatment systems for car wash wastewater with capacity between 250 - 3000 m3 per year) as well as large-scale applications (e.g. filter systems for landfill leachates with capacity above 30,000 m3 per year).

    Leachability testing of metallic wastes2005In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 23, no 5, p. 457-467Article in journal (Refereed)
    Abstract [en]

    The performance of two tests, a batch test and a percolation test for the characterization of waste as suggested in the EU council decision 2003/33/EC was investigated. The tests were carried out on two solid waste streams from a metal recycling industry. The concentrations of heavy metals such as Cu, Znand Pb were more than one order of magnitude lower than the proposed limit values. Generally, batch test values were equal or higher than percolation test values. With the proposed test procedures both materials could be considered as non-dangerous wastes. The test performance was also investigated using a leachant with higher ionic strength instead of demineralized water as prescribed. The results clearly show a significant increase in the concentration of some heavy metals. Total concentrations of phenolic compounds and polychlorinated biphenyls were less than 1 p.p.m. and 2 p.p.b., respectively. The precision of the batch and the percolation tests were on average 48 and 35%, respectively.

    Leachability testing of sludge from street gullies2006In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 24, no 3, p. 260-268Article in journal (Refereed)
    Abstract [en]

    Sludge from gullies, on two types of streets with different traffic intensity, was investigated using two recommended EU methods for leachability testing of waste: a two-stage batch test and an up-flow percolation test. The main purpose of this investigation was to gain more knowledge about these leaching test methods to be able to make future decisions on the general applicability of the proposed tests. A number of parameters were determined in the sludge as well as in the eluates obtained from the two leaching tests. These include pH, conductivity, dissolved organic carbon and inorganic ions as chloride ions. A number of metals as Cd, Cr, Cu, Hg, Ni and Zn, were determined by inductive coupled plasma-mass spectrometry and organic compounds were screened by high performance liquid chromatography-diode array UV detection and gas chromatography-mass spectrometry. It was found that the concentrations of metals and organic compounds in the sludge were several orders of magnitudes higher than the actual eluate concentrations. For all metals the concentrations were well below the proposed limit values for non-hazardous waste included in the Council decision document 2003/33/EC. Generally, concentrations obtained in batch test were equal or higher than from percolation tests. The repeatability of the percolation and the batch test were in average 28 and 17%, respectively.

    In the present study, two combinations of filter materials in filter/columns were examined for removal of total organic carbon (TOC) and polyphenols (PP) found in storm water runoff from wood storage areas in a wooden floor industry. One filter/column was packed with peat mixed with carbon-containing fly ash, while another filter/column contained only peat (without ash). The mixture of peat and ash has shown faster and higher removal capacity for TOC and faster removal with the same final removal capacity for PP (in grams of pollutant per kg of sorbent) at the saturation point. The superiority observed for the peat and ash filter is presumably due to the unique characteristics of peat and ash, which enhanced the treatment efficiency when used together in a mixture. Based on the observed results, filters formed by peat and carbon-containing ashes proved to be a potentially low-cost option for the treatment of storm water generated at storage areas of wood materials such as logs, sawdust and wood chips.

    Sensory quality of drinking water in relation to chemical and microbiological composition2019In: 13th Pangborn Sensory Scinece Symposium, 2019Conference paper (Refereed)
    Abstract [en]

    It is well known that tap water tastes different due to where the water is tapped, ie its chemical and microbiological compositions. Taste competitions have been performed in different countries to find out the most preferred tap water. With some few exceptions, no studies have been performed in which the taste of tap water is objectively described by analytical sensory methods. The purpose of this study was to evaluate quality of Swedish drinking water from different dwells with emphasis on sensory, chemical and microbiological analyses.

     

    Tap water origin from surface water and from groundwater was collected from the Swedish municipalities Svalöv and Kristianstad. The water samples were collected in 3 points in each municipality: 1. waterworks; 2. near waterworks; 3. far from waterworks. In addition the commercial water Evian was included in the analyses. Analytical sensory analyses (triangle test and quantitative descriptive analysis) were performed along with chemical and microbiological standard analyses according to Swedish drinking water standards.

     

    The results from the triangle test showed significant sensory differences between tap water from surface water and groundwater, as well as in surface water samples collected in different points. The descriptive analysis showed large differences in the perception of bitterness, minerals and off flavours. The perceived differences are in line with earlier studies pointing out inorganic ions as responsible for the taste sensations. The chemical analyses showed that the major difference between the two types of tap water was a higher mineral content and higher alkalinity in the groundwater compared to the surface water. The microbiological analyses did not show any measurable concentrations in any of the samples. There is a need for further research of chemical and microbiological effects on the flavour of tap water, with focus on microorganisms and chemical compounds in low concentrations.

    Investigation of Hard Biodegradable Pharmaceuticals Pollutants Treatment of Hospital Wastewaters2014In: Book of abstracts, 2014, p. 173-Conference paper (Other academic)
    Abstract [en]

    According to the results of the research performed in the different modern research laboratories the remnants of drugs and their derivatives are found in surface waters in France, USA, UK, Germany, Denmark and Sweden. These substances also can be found in sewage sludge, river and ocean sediments and in the municipal landfills filtrates. Some species have been found even in drinking water and ice, grou nd and ocean waters. Many studies confirmed the data of the annual drug releasing into the environment, which counts several hundred of kilograms. Thus, the investigations of negative impact of pharmaceutical substances and their derivatives on aquatic organisms have been performed  during more  than 20 years and showed an extremely negative presence of any drugs in the waters. Now, they are still  considering  as  emerging organic contaminants in the different type of waters. The main sources of water pollution by pharmaceuticals and their derivatives are wastewater from hospitals, clinics, pharmaceutical industries and domestic sewage as well. However, the main percentage of pharmaceuticals dumped into wastewaters is coming from the hospitals. This is typical for large cities, where is situated a great n um ber of hospitals and health care institutions. In the opinion of one study hospital wastewaters have been found in a 15 times higher potential ecotoxicity than the general urban have. The negative effect of pharmaceuticals influence into environment can be decrease due to application of different kinds of additional wastewater treatment as Advanced Oxidation Processes (AOPs). The main approaches of hospitals wastewater treatment in Ukraine and Sweden by implementation of AOPs method were considered in this study. The main data of this research will be presented.
