[COTONOU, SciDev.Net] Une étude publiée dans la revue Science Direct met en garde contre la présence de résidus de pesticides dans le maïs stocké au Bénin, dépassant les limites fixées par l’Union européenne.

Par exemple, « le phosphure d’aluminium a été détecté dans 40 à 100 % des échantillons, selon les localités, mais toujours à des niveaux supérieurs aux normes », explique Olivier Tonato, chercheur en entomologie agricole et en protection des végétaux, premier auteur de l’étude.

AlphaGalileo has helped us more than double our reach at SciDev.Net. The service has enabled our journalists around the world to reach the mainstream media with articles about the impact of science on people in low- and middle-income countries, leading to big increases in the number of SciDev.Net articles that have been republished.
