Emerging contaminants (ECs) represent a group of synthetic, natural and some microbial contaminants either naturally occurring or introduced in the environmental matrices, profoundly in the water bodies (Richardson & Ternes, 2017) and little in the atmosphere (Barroso et al., 2019). Many of these contaminants may have been present in the environment for a long time but are only now have they become detectable due to advances in analytical chemistry. The contamination levels of a broad group of 99 emerging and persistent organic contaminants (POCs) in the roe/gonads of the sea urchin Paracentrotus lividus were reported for . work further explored the formation mechanisms of such DOM by looking into the respective reactions of intracellular organic matter (IOM) and cell debris in activated sludge with NaOCl. Organic wastes like biosolids, sewage effluent, and animal waste contain PPCP residues. Antibiotics and pharmaceuticals The main transfer pathway for antibiotics and pharmaceuticals used in human medicine to enter the environment is via wastewater treatment plants (WWTPs). Because they can be transported by wind and water, most POPs generated in one country can and do affect people and wildlife far from where they are used and released. ( 2018) measured the legacy and emerging organohalogenated contaminants (OHCs) in edible wild aquatic organisms sampled from the Pearl River and Dongjiang River in a representative industrial and urban region in China. Steroidal hormones are either synthetic or naturally occurring forms of estrogen that are released from the adrenal cortex and other parts of the animal and human body ( Biga et al., 2019 ).

According to EPA, an emerging contaminant is a chemical or material characterized by a perceived, potential, or real threat to human health or the environment or by a lack of published health standards. The main analytical Different inoculums were spiked with nine emerging contaminants at nominal concentrations ranging between 1 to 2 mg/L (ibuprofen, diclofenac, naproxen, acesulfame, sucralose, aspartame, cyclamate, linear alkylbenzene sulfonates, and secondary alkyl sulfonates). . A contaminant also may be "emerging" because of the discovery of a new source or a new pathway to humans. Emerging Organic Pollutants in Waste Waters and Sludge Starting at $47.47. The recalcitrance of some emerging organic contaminants through conventional water treatment systems may necessitate advanced technologies that use highly reactive, non-specific hydroxyl radicals. Although the risks of micropollutants in sources of water are partly recognized, interpretation of consequences are controversial; thus, the future effects of altered water with micropollutants remains uncertain and may constitute a point of concern for human beings when potable water consumption .
