The removal of microplastic from wastewater collected a plastic recycling facility was investigated, using laboratory scale sand-filter. Wastewater samples were before and after the onsite sand-filter, for characterization different polymer types, sizes, shapes. A considerable difference in characteristics concentrations microplastics observed sand-filtration, demonstrating differences source and/or potential contamination sand-filter operated at facility. distribution polymers showed...
The applicability of silicone rubber and low-density polyethylene (LDPE) as passive sampling materials for target nontarget analyses moderately polar nonpolar substances was assessed through a field deployment samplers along small, polluted stream in Oslo, Norway. Silicone LDPE identical surface area (but different volumes) were deployed at 6 sites the River Alna 49 d. Quantitative analysis by gas chromatography-mass spectrometry (quadrupole, single-ion monitoring mode) demonstrated that...
Snowmelt, surface runoff, or stormwater releases in urban environments can result significant discharges of particulate matter-bound polycyclic aromatic hydrocarbons (PAHs) into aquatic environments. Recently, more-specific activities such as road-tunnel washing have been identified contributing to contaminant load waters. However, knowledge PAH accessibility matter (PM) origin that may ultimately be released waters is limited. In the present study, we evaluated PAHs associated with seven...
ABSTRACT The temperature-driven adaptation of the bacterial community in peat was studied, by altering temperature to simulate self-heating and a subsequent return mesophilic conditions. technique used consisted extracting from using homogenization-centrifugation measuring rates thymidine (TdR) or leucine (Leu) incorporation extracted at different temperatures. Increasing incubation 25°C 35, 45, 55°C resulted selection communities whose optimum temperatures for activity correlated Although...
ABSTRACT The use of the phospholipid fatty acid (PLFA) composition microorganisms to detect previous self-heating events was studied in naturally self-heated peat and incubated under temperature-controlled conditions. An increased content total PLFAs found compared that unheated peat. Two PLFAs, denoted T1 T2, were detected only Incubation samples at 25 55°C for 4 days indicated T2 produced from with different optimum temperatures. This confirmed by isolation bacteria 55°C, which but not T1....
Sedimentation ponds have been shown to accumulate several groups of contaminants, most importantly polycyclic aromatic compounds (PACs) and metals. But also, other urban organic pollutants be present, including polybrominated diphenyl ethers (PBDEs), organophosphate (OPCs) benzothiazoles (BTs). This investigation aimed at determining the occurrence these four contaminants in sedimentation determine their transport from water/sediment organisms. PACs, alkylated PBDEs; OPCs BTs were determined...
Thirty two polychlorinated biphenyl congeners (PCBs), hexachlorobenzene (HCB) and pentachlorobenzene (PeCB) were analysed in passive sampler extracts from surface water-exposed semipermeable membrane devices (SPMDs) bed sediment samples a small urban watercourse, the River Alna (Oslo, Norway). Performance reference compound-corrected data samplers deployed at three sites along river used to track PCB contamination overlying water. SPMDs able detect an increase dissolved concentrations site...
A data register study was performed in order to identify the amounts of hazardous substances products related motorized transport Norway during 2012. The were selected from legislative investigations by European Chemicals Agency (ECHA), Union (EU), and Norwegian Environment (NEA). Information regarding 52 product categories associated with traffic-related activities obtained Product Register administrated NEA. Substances present on ECHA list very high concern (SVHC), NEA national priority...
