In order to assess risks the natural environment from microplastics, it is necessary have reliable information on all potential inputs and discharges. This relies stringent quality control measures ensure accurate reporting. Here we focus wastewater treatment works (WwTWs) complex sample matrices these provide. Composite samples of both influent effluent were collected over a 24 h period two se...

Meat industry waste waters are 5 to 10 times as strong (BOD)as domestic sewage and contain much higher nitrogen, phosphorus and grease concentrations. Conservation measures and pretreatment facilities are aimed principally at blood (or blood water), casing slimes, wet rendering (tank water), paunch manure, yard drainage and hog hair.

The fate of 14 antidepressants along with their respective N-desmethyl metabolites and the anticonvulsive drug carbamazepine (CBZ) was studied in 5 different sewage treatment plants (STPs) across Canada. Using two validated LC-MS/MS analytical methods, the concentrations of the different compounds were determined in raw influent, final effluent and treated biosolids samples. Out of the 15 compo...
