POCIS evidence Yaoundé’s rivers pesticides contamination.
Résumé
Yaoundé’s freshwater supply is crucial to the local population and to the production of crops in its humid lowlands [1]. However,
contribution of agricultural activities on water pollution is likely to occur but has never been documented in Yaoundé. Thus, in situ physico-chemical measurements, passive (POCIS) and grab sampling [2][3] was deployed to monitor contamination from 32 polar pesticides in urban and peri-urban tropical watershed.
