However, several MPs are poorly biodegradable and toxic to the microbial consortium in wastewater treatment systems. In practice, MPs exist at only small quantities in wastewater, they cannot participate in the catabolic and anabolic processes of microbes. That is, bacteria are unable to consume ...
The present review article summarizes the recent findings reported in the literature with regard to the use of molecularly imprinted polymers for the removal of arsenic from water and wastewater. MIPs are polymers in which a template is employed in order to enable the formation of recognition sites...
Plain provides saffron to much of the world, no regional groundwater quality (GQ) assessment has yet been undertaken. Given the region's potential for saltwater intrusion and heavy metal contamination, it is important to assess the GQ and determine its main probable source of pollution (MPSP)....

1.3. Plastic Particle Sources The life cycle stages of plastic particles are in the following order: manufacture, transportation, use, recycling, and treatment [48]. They cannot be effectively collected and removed at wastewater stations due to the small particle sizes involved, resulting in those ...
