[en] Plant protection products play a very important role in agriculture. However, their misuse can have serious negative impacts both on human health and environment. A study was carried out to identify the plant protection products used in the Niger River valley and to observe the local pesticide management practices. Ten active substances were identified as the most used chemicals by farmers. Their toxicological properties were characterized and their respective Potential Dermal Exposures (PDE) was evaluated in order to assess the risk level for the local small growers. The UK Predictive Operator Exposure Model was used to quantify the PDE during mixing/loading and application according to the local practices. The survey shows that the most common active substances are organophosphate or pyrethroids insecticides. In addition, some other prohibited and counterfeit pesticides cocktails are also used. All active substances used in Niger River valley are highly toxic. When sprayed without personal protective equipment (PPE) they could induce significant harmful impacts on the human health after exposure. The predictive exposure levels vary from 0.0013 mg/kg bw/day to 0.4125 mg/kg bw/day, several times higher the Acceptable Operator Exposure Level (AOEL) for all actives substances. The survey also revealed that 76% of operators do not use any PPE during mixing/loading or spraying. Other bad practices observed in study area can increase the exposure of operators. Moreover, local consumers could also be exposed through intake of pesticide residues on harvested products.
