  This study investigated the presence of four pesticides (carbaryl, methomyl, carbofuran and chlorpyrifos) and two personal care products (PCPs) i.e., triclosan (TCS) and caffeine in River Kabul, upper River Indus and Kalpani stream receiving untreated wastewater from major towns in northern Pakistan. PCPs were also examined in domestic wastewater in Mardan district, Pakistan with untreated sewage disposal as common elsewhere in the country. Analysis were performed using liquid chromatography with a triple quadrupole tandem mass spectrometry (LC-MS/MS). All the target pesticides were detected in surface water bodies and in domestic sewage in various concentrations. Methomyl in River Kabul at maximum concentration of 8.3 μg/L was found above its reported LC50 for water fleas. PCPs level in sewage were comparable to other countries but in the absence of any treatment practice, environ.. Read More»
