PG - 546 LID - 10.1007/s10661-020-08452-6 [doi] LID - 546 AB - Seven pesticides, profenofos, metalaxyl, lambda-cyhalothrin, 4,4'-DDT, 4,4'-DDE, and alpha- and beta-endosulfan, were determined in vegetables (tomato, onion) from 20 locations and surface waters from 12 locations in the Central Rift Valley (CRV) of Ethiopia. Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) and solid phase extraction (SPE) methods were used for the vegetables and water, respectively. In 2.5% of the tomato samples, profenofos was detected above European maximum residue limits (MRLs), in 12.5% of the samples metalaxyl, and in 2.5% alpha- and beta-endosulfan. In 5% of the onion samples, profenofos was detected above European MRLs, in 7.5% of the onion samples metalaxyl, and in 5% lambda-cyhalothrin. In surface water, profenofos was detected at the highest concentration of 2300 mug/L in the Bulbula River, 890 mug/L near the agricultural land north of Lake Ziway (ANLZ-1), 1700 mug/L in the floriculture effluent (FE-1), and 900 mug/L in tap water at the Batu Drinking Water (BDW) supply. These results show that the levels of pesticides are in several cases substantially elevated, and emphasize the need of regular pesticide monitoring programs for surface waters and vegetables in the Ethiopian CRV.
