On site determination of Sulfotep air levels in a fumigating greenhouse.
Sulfotep air levels in a greenhouse were monitored continuously in real time, for 4-40 hours after fumigation, using a trace atmospheric gas analyzer system. Sulfotep air levels were below the threshold limit value of 15 ppb following overnight ventilation but, when ventilation was stopped to conserve heat, the Sulfotep air levels exceeded the threshold limit value. This study also showed that worker activity in the greenhouse significantly increased Sulfotep air levels. It is recommended, therefore, that ventilation of a greenhouse following Sulfotep fumigation should continue during the entire day and workers exposed to such conditions should wear appropriate protective equipment.
