O arroz (Oryza Sativa. L) é um alimento básico e, no Paquistão, 5547 mil toneladas de área são dedicadas ao cultivo de arroz. A produtividade do arroz pode ser aumentada com o uso de pesticidas, mas, uma vez que esses produtos quÃmicos tóxicos são aplicados na cultura do arroz, alguns dos seus resÃduos permanecem nas culturas. A presença desses pesticidas pode representar um risco para os seres humanos e também para o ambiente, direta ou indiretamente. Assim, o presente estudo foi realizado para estimar o nÃvel residual de alguns pesticidas organoclorados (OCPs) selecionados em grãos de arroz e amostras de palha coletadas em diferentes áreas de Punjab, no Paquistão. De acordo com o presente estudo, não foi observada variação significativa entre todas as amostras coletadas em diferentes locais de amostragem. No entanto, o nÃvel de OCPs na palha e nos grãos de arroz excedia os limites máximos de resÃduos (MRLs). E o consumo de grãos de arroz por seres humanos pode representar um risco de câncer a longo prazo. Da mesma forma, os animais não estão seguros ao consumir palha de arroz como forragem.
