  abstract = {{U}rban agriculture is crucial to local populations, but the risk of it contaminating water has rarely been documented. {T}he aim of this study was to assess pesticide contamination of surface waters from the {M}efou watershed ({Y}aounde, {C}ameroon) by 32 selected herbicides, fungicides, and insecticides (mainly polar) according to their local application, using both grab sampling and polar organic compounds integrative samplers ({POCIS}). {T}hree sampling campaigns were conducted in the {M}arch/{A}pril and {O}ctober/{N}ovember 2015 and {J}une/{J}uly 2016 rainy seasons in urban and peri-urban areas. {T}he majority of the targeted compounds were detected. {T}he quantification frequencies of eight pesticides were more than 20% with both {POCIS} and grab sampling, and that of diuron and atrazine reached 100%. {S}patial differences in contamination were evidenced with higher contamination in urban than peri-urban rivers. {I}n particular, diuron was identified as an urban contaminant of concern because its concentrations frequently exceeded the {E}uropean water quality guideline of 0.200 mu g/{L} in freshwater and may thus represent an ecological risk due to a risk quotient > 1 for algae observed in 94% of grab samples. {T}his study raises concerns about the impacts of urban agriculture on the quality of water resources and to a larger extent on the health of the inhabitants of cities in developing countries.},
