Microplastics are recognized as common pollutants in aquatic environments that may have adverse effects on human health. A study evaluated the occurrence and removal efficiency of microplastics at different treatment stages in a typical DWTP with pulse clarification, showing good removal efficiency at the sand filtration stage and strong associations with other components in water. The results suggest that DWTPs with pulse clarification systems may have comparable microplastics removal efficiency to advanced DWTPs.
Microplastics are recognized as ubiquitous pollutants in aquatic environments; however, very little study is done on their occurrence and fate at drinking water treatment plants (DWTPs). Though, the toxic effect of microplastics on human health is not yet well established; there is global concern about their possible ill effect on the human. Hence, the present study evaluates the occurrence of microplastics at different treatment stages of a typical DWTP with pulse clarification and its removal efficiency. In the test DWTP, raw water, sourced from river Ganga, was found to contain microplastics 17.88 items/L. Cumulative microplastic removal at key treatment stages viz. pulse clarification and sand filtration was found to be 63% and 85%, respectively. The study also revealed higher microplastic abundance on the sand filter bed due to the screening effect. The most frequently occurring microplastics were fibers and films/fragments with polyethylene terephthalate and polyethylene as a major chemical type. The t-distributed stochastic neighbor embedding machine learning algorithm revealed a strong association between microplastic abundance with turbidity, phosphate and nitrate. The test DWTP with a pulse clarification system was having comparable microplastics removal efficiency with previously reported advanced DWTPs.

Dhruba Jyoti Sarkar, Saswata Goswami, Swarupananda Sahu, Bijay Kumar Behera, Pranaya Parida, Shyamal Chandra Sukla Das, Basanta Kumar Das, Partha Sarkar, Debabrata Pradhan, Subhankar Mukherjee, Souvik Pal, Vipul Bansal

Summary: In this study, polyvinyl alcohol (PVA) capped AgNPs (AgNPs@PVA) were used as a nanocarrier to fabricate an acetylcholinesterase (AChE) biosensor for the detection of organophosphate (OP) pesticides. The AChE enzyme was immobilized onto a drop casted AgNPs@PVA layer on a glassy carbon electrode (GCE) to fabricate the electrochemical biosensor. The biosensor measured the peak current at 0.6 V generated by the AChE-mediated hydrolysis of acetylthiocholine (ATCl) to thiocholine and its subsequent oxidation to dimer through differential pulse voltammetry (DPV). A model OP pesticide, malathion, was used to hinder the AChE hydrolysis activity of the sensor probe, and the inhibition effect was found to be proportional to the concentration of malathion. The fabricated biosensor showed linearity in the range of 0.01 to 1 ng/mL of malathion at optimal conditions, with a detection limit (LOD) of 2.6 pg/mL. The AChE biosensor exhibited good selectivity for OP pesticides and demonstrated efficiency in real sample analysis.
