ABSTRACT
Objective To make a passive personal sampler for the determination of the styrene in the air. Methods To make a passive personal sampler for the determination of the styrene in the air. Results Under the condition of wind velocity of 100-600 cm/s, relative humidity of 40%-80% and temperature of 10-40 ℃, the sampling flux of the passive sampler was 61.8 ml/min, the capacity was 5.95 mg, the shortest sampling time was 30 min, the self life was at least 30 days, the storage stability was at least 14 days, the RSDs were 8.07%-9.37%. Conclusion This new kind of passive personal sampler can be used as a new device for the determination of the styrene in the air.
ABSTRACT
The exposures to carbamate pesticides (BPMC specifically) of agricultural workers were estimated by collecting pesticide in air by personal sampler and by analyzing with gas chromatography. Data revealed that the highest BPMC concentration in the aspirated air was 7.7 mg/m3. Concentrations were generally higher in the group whose spray conditions were controlled than the group uncontrolled. Actual concentrations were relatively lower than the values predicted theoretically. These findings suggest that personal sampler be useful in the estimation of pesticide exposure.
