Le riz (Oryza Sativa. L) est un aliment de base et, au Pakistan, 5 547 000 tonnes sont cultivées. La productivité du riz peut être améliorée grâce à l'utilisation de pesticides, mais une fois que ces produits chimiques toxiques sont appliqués sur les cultures de riz, certains de leurs résidus restent sur les cultures. La présence de ces pesticides peut présenter un risque pour les humains et pour l'environnement, de manière directe ou indirecte. La présente étude a donc été menée afin d'estimer le niveau résiduel de certains pesticides organochlorés (OCP) sélectionnés dans des échantillons de grains de riz et de paille prélevés dans différentes régions du Pendjab, au Pakistan. Selon la présente étude, aucune variation significative n'a été observée entre tous les échantillons prélevés sur différents sites d'échantillonnage. Cependant, le niveau d'OCP dans la paille et les grains de riz dépassait les limites maximales de résidus (LMR). La consommation de grains de riz par les humains peut présenter un risque de cancer à long terme. De même, les animaux ne sont pas en sécurité lorsqu'ils consomment de la paille de riz comme fourrage.
