AB  - Pesticides in the environment can pose serious risks to aquatic ecosystems. This 
      study focused on the existence of 27 pesticides, including 13 pesticides 
      regulated by the Stockholm Convention as persistent organic pollutants (POPs) and 
      14 commonly used pesticides in three urban rivers in Beijing that receive 
      effluents from three municipal wastewater treatment plants (MWTPs). Among the 27 
      pesticides, 12 were detected at least once over a period of 4 seasons. Atrazine, 
      aldrin and dieldrin were universally found in the three rivers, with the highest 
      concentrations being 311, 163 and 23.3 ng/L, respectively. HCHs, DDTs, heptachlor 
      and endosulfan, which are POPs, were detected at lower concentrations (ND-16.7 
      ng/L). Most of the insecticides and some of the herbicides in the rivers 
      originated from MWTP effluents. The risk assessment results showed that aldrin 
      posed medium risk (0.1 </= RQ < 1) to fish, and atrazine exhibited medium risk to 
      both fish and algae. Despite the implementation of the Stockholm Convention and 
      the upgrades of MWTPs emitting ozone, high loads of aldrin, atrazine and dieldrin 
      were discharged to the rivers. Efforts should be devoted to identifying POP 
      pesticide sources and upgrading MWTPs with other technologies to ensure the 
      ecological safety of rivers.
