Chlorinated pesticide occurrence in the Uruguay River (Argentina-Uruguay)

Distribution and ECo-Toxicological Risk Assessment of Legacy Persistent Organic Pollutants in Surface Water of Talar, Babolrood and Haraz Rivers

“…Lindane concentration in this study was lower than Karun River (1585 ng/L) [44], Lake Parishan (58 ng/L) [45], Lake Tashk (82 ng/L) [46], Anzali wetland (20 ng/L) [47] and Shahid Rajaei Dam (<LOQ to 170 ng/L) [48] in Iran. Compared with studies across the world, lindane concentration were observed to be lower than Ibadan streams (100 ng/L) and Lagos Lagoon (182 ng/L) [58][59][60][61]; however, the average concentration was higher than River Nile and Moscow River [50,53], Yongding River (0.16 ng/L) [54], Chenab River (0.85 ng/L) [55], Ravi River (0.73 ng/L), Uruguay River (2.2 ng/L) [56], Hooghly River (26 ng/L) [49], Pearl River Estuary (13.01 ng/L) [51] and Iberian Peninsula (39.23 ng/L) [52].…”

Temporal and spatial variations of organochlorine pesticides in the suspended particulate matter from Lake Chaohu, China

“…It was reported that OCPs were widely distributed in freshwater bodies, including ponds, rivers, lakes, reservoirs and estuaries (e.g., Dua et al, 1996;Janiot et al, 1994;Maskaoui et al, 2005;Tao et al, 2007;Zhou et al, 2008;Yamashita et al, 2000;Xu et al, 2013). OCPs could enter an aquatic environment through ways such as surface runoff, wastewater discharge from pesticide factories, dry and wet atmospheric deposition, and washing of pesticide containers and agricultural equipment (Ali et al, 2014).…”

Pesticides Reaching the Environment as a Consequence of Inappropriate Agricultural Practices in Argentina

“…As in De La Plata River, HCH isomers were the most commonly detected compounds, with concentrations ranging from the detection limits to 10 ng/L. Heptachlor, Heptachlor-epoxide, Aldrin, Dieldrin, p-p´DDE and p-p´DDT were occasionally encountered while o-p´DDE, p-p´DDD, o-p´DDD and o-p´DDT were never detected (Janiot et al 1994). In the lower Paraná River's Delta the concentrations of chlorinated pesticides in water were low and similar between sites (3.9±5.1 ng/L), as informed by Cataldo el al.…”
