A multi-residue screening method for simultaneous measurement of a wide range micropollutants in drinking water (DW) resources was developed. The applied field study central Sweden on from source to tap, including samples surface (upstream and downstream wastewater treatment plant, WWTP), intake before after DW plant (DWTP, pilot full-scale), treated leaving the tap at end users. Low detection limits (low ng L-1 levels) were achieved by using large sample volumes (5 L) combined with ultra...
Per- and polyfluoroalkyl substances (PFAS) are persistent synthetic contaminants that present globally in water exceptionally difficult to remove during conventional treatment processes. Here, we demonstrate a practical train combines foam fractionation concentrate PFAS from groundwater landfill leachate, followed by an electrochemical oxidation (EO) step degrade the PFAS. The study combined up-scaled experimental approach with thorough characterization strategies, including target analysis,...
The enantiomer ratio (ER) is currently the standard descriptor of enantiomeric (chiral) signatures for environmental samples. In this paper, we argue adoption fraction (EF) as by showing drawbacks to use ER. superior because it provides a more meaningful representation graphical data and easily employed in mathematical fate expressions. Several useful expressions are presented that allow EF be used tracking apportioning chemical movement between compartments investigating microbial...
The aim of this study was to assess per- and polyfluoroalkyl substances (PFASs) in the Swedish aquatic environment, identify emission sources, compare measured concentrations with environmental quality standards (EQS) (drinking) water guideline values. In total, 493 samples were analyzed 2015 for 26 PFASs (∑26PFASs) surface water, groundwater, landfill leachate, sewage treatment plant effluents reference lakes, focusing on hot spots drinking sources. Highest ∑26PFAS detected (13 000 ng L–1)...
On-site sewage treatment facilities (OSSFs), which are used to reduce nutrient emissions in rural areas, were screened for anthropogenic compounds with two-dimensional gas chromatography-mass spectrometry (GC×GC-MS). The detected prioritized based on their persistence, bioaccumulation, ecotoxicity, removal efficiency, and concentrations. This comprehensive prioritization strategy, was the first time OSSF samples, ranked galaxolide, α-tocopheryl acetate, octocrylene,...
A novel and efficient organic waste management strategy currently gaining great attention is fly larvae composting. High resource recovery efficiency can be achieved in this closed-looped system, but pharmaceuticals pesticides could potentially accumulate every loop of the treatment system spread to environment. This study evaluated fate three (carbamazepine, roxithromycin, trimethoprim) two (azoxystrobin, propiconazole) a composting control with no larvae. It was found that half-life all...
This study demonstrates that regulatory databases combined with the latest advances in high resolution mass spectrometry (HRMS) can be efficiently used to prioritize and identify new, potentially hazardous pollutants being discharged into aquatic environment. Of approximately 23000 chemicals registered database of National Swedish Product Register, 160 potential organic micropollutants were prioritized through quantitative knowledge market availability, quantity used, extent use on market,...
There is growing worry that drinking water can be affected by contaminants of emerging concern (CECs), potentially threatening human health. In this study, a wide range CECs (n = 177), including pharmaceuticals, pesticides, perfluoroalkyl substances (PFASs) and other compounds, were analysed in raw collected from treatment plants (DWTPs) Europe Asia 13). The impact activities was reflected large numbers compounds detected 115) high variation concentrations the (range 15-7995 ng L−1 for...
Per- and polyfluoroalkyl substances (PFAS) are of concern for their ubiquity in the environment combined with persistent, bioaccumulative, toxic properties. Landfill leachate is often contaminated these chemicals, therefore, development cost-efficient water treatment technologies urgently needed. The present study investigated applicability a pilot-scale foam fractionation setup removal PFAS from natural landfill novel continuous operating mode. A benchmark batch test was also performed to...
Per- and polyfluoroalkyl substances (PFAS) are known to be persistent, bioaccumulative, have adverse health effects, but very little is about PFAS in the terrestrial environment factors influencing their distribution. This paper presents one of first comprehensive studies investigating (n = 28) background forest soils 27) on national scale across Sweden. The results showed that 16 28 target were present all sites contained at least three compounds, with total concentrations ranging between...
Anaerobic digestate based on food waste is increasingly used as fertilizer in production. This study examined the characteristics of anaerobic from three biogas plants Sweden. The characterization included measurements heavy metals (n = 7), chemicals emerging concern (CECs), such currently drugs and pesticides 133), an extended range food-borne pathogens, including two notable sporeformers some widespread antibiotic-resistant bacteria. amounts Escherichia coli, enterococci, Salmonella...
Foam fractionation has recently attracted attention as a low-cost and environmentally benign treatment technology for water contaminated with per- polyfluoroalkyl substances (PFAS). However, data on the mass balance over foam process are scarce when available, gaps in often identified. This study verified high efficiency of pilot-scale system removal PFAS from industrial aqueous film-forming foam. ΣPFAS reached up to 84 % perfluorooctane sulfonic acid (PFOS) 97 %, but short-chain...
PER: and polyfluoroalkyl substances (PFAS) are ubiquitously distributed in wastewater, due to their numerous uses industry consumer products, but little is known of PFAS mass flows municipal wastewater network systems within treatment plants (WWTPs). This study assessed 26 a WWTP, provide new insights into sources, transport, fate different steps. Wastewater sludge samples were collected from pumping stations the main WWTP Uppsala, Sweden. composition profiles used identify sources sewage...
Aqueous concentrations of polychlorinated dibenzo-p-dioxins and -furans (PCDD/Fs) as well biphenyls (PCBs) in the open sea have heretofore been measured by filtering extracting large amounts water. Measurement freely dissolved with this technique is difficult because corrections for sorption to organic matter. In study we use a novel, more economic using equilibrium passive samplers consisting 17-microm thin polyoxymethylene (POM-17), capable measuring aqueous (Cw) pristine (i.e.,...
Little is known about the impact of emissions micropollutants from small and large-scale sewage treatment plants (STPs) on drinking water source areas. We investigated a populated catchment that drains into Lake Mälaren, which for around 2 million people including inhabitants Stockholm, Sweden. To assess persistence, mobility, bioavailability bioaccumulation 32 structurally diverse emerging organic contaminants, sediment, integrated passive grab samples were collected along River Fyris, The...
