Title Real time monitoring of methomyl air levels during and after spraying in a greenhouse
Bibliographic information Mar. 1982, Vol.43, No.3, p.190-195. Illus. 8 ref.
Abstract Methomyl concentration levels were monitored before, during and for 24h after the spraying of aqueous solutions of the insecticide in a commercial greenhouse containing roses. All measurements were made in real-time using a mobile atmospheric pressure chemical ionisation mass spectrometer system. Concentrations detected in the gas phase were in the range <1-7ppb. After spraying, the methomyl concentrations correlated directly with temperature, degree of air circulation and worker activity within the greenhouse. Methomyl was present in the aerosol phase in the greenhouse air for 24h after spraying.
