TEMPERATURE-DEPENDENCY AND HUMIDITY-DEPENDENCY OF PESTICIDE BEHAVIOR IN INDOOR SIMULATION

From a view point of safety assessment of pesticides applied within a room, three kinds of Fugacity models had been developed: aerosol space spraying (SPRAY-MOM), electric vaporizer (VAPOR-MOM) and broadcast sp raying model (CARPET-MOM). In the present study, these models were imp roved so as to trace the pesticide behavior when room temperature and humidity are varied. The sensitivity analysis clarified that temperatu re entirely influenced the concentrations and amounts of a pesticide i n the three models, while humidity only affected those in the broadcas t spraying model. Thus, the modified models now describe time-dependen t aerial concentrations and amounts of pesticides on floor, wall and c eiling under various room temperature and humidity conditions.
