Abstract Recent studies suggest per‐ and polyfluoroalkyl substances (PFAS) are ubiquitous in rivers worldwide. In the Asia‐Pacific region, frequency of PFAS detection is increasing. However, overwhelming majority data represent high population urbanized river catchments. this study, we investigate occurrence major Philippines systems characterized by both low densities. Pasig Laguna de Bay River, which drains a urban conurbation, detected at concentrations typical global rivers. Unexpectedly, did not detect water or sediments density catchments, despite our instrument limits being lower than vast reported We hypothesize that septic tanks, as dominant wastewater treatment practice may control release into groundwater Philippines. no currently exist to validate supposition. More broadly, findings highlight need for more representative sampling analysis accurately regional frequencies trends.

The widespread occurrence of new and emerging persistent organic pollutants (NEPs POPs) in surface water poses a risk to drinking supply consequently human health. aim this work was investigate the potential transport 42 target NEPs POPs (including per-and polyfluoroalkyl substances (PFAS), pharmaceuticals, pesticides bisphenols) along rural urban environments three rivers England. type concentrations varied between sampling days points. Two pharmaceuticals (diclofenac ibuprofen), two (diethyl-meta-toluamide (DEET) prosulfocarb) range PFAS were detected above method detection limit. observed include restricted perfluorooctanoic acid (PFOA), perfluorooctanesulfonic (PFOS) newer generation substitute 6:2 fluorotelomer sulfonate (6:2 FTS). levels PFOS diclofenac all studied exceeded European environmental quality standard (EQS). high frequency river Ouse suggests their persistence contaminate connecting tributaries. An assessment ecological prosulfocarb samples from Ouse, using quotient method, showed algae, planktonic crustaceans, fish. Our results suggest that presence 12 POPs, could potentially be influenced by anthropogenic activities across rivers. study highlights need for continuous monitoring new-generation chemicals waters understand impact on ecosystem public

Per- and polyfluoroalkyl substances (PFASs) are a class of manufactured organic chemicals that widely employed for their heat-, oil-, water-resistant properties. Studies have shown the bioaccumulation PFASs in living organisms related health effects sufficient classifying them as group toxicants worthy great concern further study. While travel through air soil, contamination water pathways proves to be most common route exposure. We analyzed from three different wastewater treatment plants (WWTPs) throughout Arizona show that, despite efforts, they persist contaminants sources. Using U.S. Environmental Protection Agency method 1633, seasonally obtained field samples were prepared analysis liquid chromatography–tandem mass spectrometry. A total 24 taken at stages process assess proficiency removal processes during remediation. Duplicate each Tucson’s WWTP Flagstaff’s before after chlorination, sites Yuma County, upstream effluent, downstream WWTP, chlorination. From Yuma, perfluorooctanesulfonic acid, perfluorooctanoic perfluorohexanesulfonic acid detected but levels below limits quantification. PFBS was Tucson up 4.52 ng/L 73.53 ng/L, respectively. The instrument level detection and, therefore, characterized non-detects.
