Trends of Emerging Contaminants in the Aquatic Environment—Risk Assessment and Management Strategies
摘要
Emerging contaminants (ECs) are a burgeoning class of pollutants which include pharmaceutical drugs, personal care products (PCPs), home care products, pesticides, and industrial chemicals that are finding their way into water bodies because of improved technologies and population growth. Such pollution would not be considered “recently developed” since ECs are not a spillage or emission from a singular source but rather a concoction of micropollutants that enter the environment through various trajectories but can be extremely damaging due to their characteristics and distributions in the ecosystem. ECs pose a threat to ecosystems or human health due to their permanence, potential factories or bioaccumulation, and ability to disrupt the ecological niche. ECs can leach through the food chain caused by environmental contamination which leads to long exposure effects. It is important that global management strategies be adopted. Numerous studies have pointed out that conventional wastewater treatment methods such as filtration, sedimentation, and activated sludge systems do not treat nor eliminate all ECs and their residue levels. Advanced removal methods, including advanced oxidation processes (AOPs), adsorption, hybrid membrane bioreactors (MBRs), and integrated bioremediation systems, have shown a remarkable impact. By integrating technological innovations with appropriate policies and regulatory frameworks, it is feasible to mitigate the risks linked to ECs and safeguard water resources and ecosystems.
