Assessment of environmental pesticides exposure of farmers living nearby the paddy fields using mathematical modelling
Paddy farmers can be exposed to pesticides while handling pesticides, but they may also be indirectly exposed to applied pesticides in the fields, by living nearby the agricultural fields. This study investigates how pesticide usage of the farmers in the paddy field may affect pesticide exposure and...
