Emerging pollutants (EPs) are chemicals known to cause major impacts on the terrestrial, aquatic life and human health as a result of their chronic acute toxicity. Although lots studies EPs behavior in environment currently available literature, an urgent requirement exists complete toxicological develop implement efficient ecological methods for removal. This paper raises some relevant problems related water pollution with EPs, risks they can generate humans opportunities reduce effects by Categories emerging concern environment, sources, fate impacts, examples discussed. Organic UV filters shortly presented relative new category, focus need extensive experimental environmental occurrence, Furthermore, sources resulting from discharging directly into rivers wastewater treatment plants examined. The incidence is also considered. removal solution risk mitigation addressed, emphasis several non-conventional processes involving biological EPs. provides critical look at current challenges posed presence comments recommendations further research impact improve performance developed

Abundance, fate, and effects of pharmaceuticals and personal care products in aquatic environments

Journal of Hazardous Materials, Год журнала: 2021, Номер 424, С. 127284 - 127284

Pharmaceuticals and personal care products (PPCPs) are found in wastewater, thus, the environment. In this study, current knowledge about occurrence fate of PPCPs aquatic systems-including wastewater treatment plants (WWTPs) natural waters around world-is critically reviewed to inform state science highlight existing gaps. Excretion by humans is primary route entry into municipal systems, but significant contributions also occur through emissions from hospitals, manufacturers, agriculture. Abundance raw influenced several factors, including population density demography served WWTPs, presence hospitals drugs manufacturers sewershed, disease burden served, local regulations, climatic conditions. Based on data obtained analgesics, antibiotics, stimulants (e.g., caffeine) most abundant wastewater. conventional removal occurs during secondary treatment, overall exceeds 90% for treatable PPCPs. Regardless, total PPCP mass discharged with effluent an average WWTP receiving (7.35-20,160 g/day) still considerable, because potential adverse effects some (such as ibuprofen) organisms within measured concentrations surface waters.

Survey of 218 organic contaminants in groundwater derived from the world's largest untreated wastewater irrigation system: Mezquital Valley, Mexico

The Mezquital Valley system is the world's oldest and largest example with regard to use of untreated wastewater for agricultural irrigation. Because artificial high recharge associated aquifers, groundwater extracted human consumption, there are plans this as a water resource Mexico City. Thus, study analyzed 218 organic micro-contaminants in wastewater, springs, from Valley. Five volatile compounds (VOCs) nine semi-volatile (SVOCs) were detected used Only two SVOCs [bis-2-(ethylhexyl) phthalate dibutyl phthalate] all canals sources, whereas no VOCs springs. Of 118 pharmaceutically active (PhACs) 7 reproductive hormones measured, 65 PhACs 3 wastewater. these, metformin, caffeine, acetaminophen account almost sixty percent total Nevertheless, 23 where majority these have low detection frequencies. sulfamethoxazole, N,N-diethyl-meta-toluamide, carbamazepine, benzoylecgonine (primary cocaine metabolite) frequently groundwater, suggesting that although soils act filter adsorbing degrading pollutant content still reach aquifer. Therefore, presence PhACs, together levels endocrine disruptor bis-2-(ethylhexyl) phthalate, indicate sources derived studied aquifers may pose risk consumer health.
