An Estimation of Carbamate Pesticide Exposure in a Rural Area: A pilot study using personal sampler and gas chromatography.: Byung Hae Kim, Yong Sik Kim, Jin Su Choi; Korean J Prev Med. 1990;23(2):201-206.

Abstract PDF: 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.; Summary

A Study on the Distributions of Paraoxonase Activity and the Factors affecting Paraoxonase Activity of a Rural opulation.: Jaecheol Song, Hung Bae Park; Korean J Prev Med. 1990;23(2):194-200.

Abstract PDF: The paraoxonase (E. C. 3.1.1.2.) is a major enzyme to detoxicate the organophosphorus and carbamate which are the most widely used as the agricultural spraying insecticides. To investigate the distributions of plasma paraoxonase activity and the fators affecting the enzyme activity, the plasmas of 945 Korean rural population were analyzed with the modified Krisch's direct sphectro;hotometry method. Three indices of the enzyme activity-basal activity, stimulated activity (by NaCl), % stimulation -were obtained from the analysis. Three indicies suggested unimodal distributions, so we couldn't identify the low activity group; risk group to organophosphorus & carbamate insecticides poisoning. There is no significant relation between 3 activity and the stimulated activity have significant relationship and high coefficient of determination with the activities of their parents (r2=0.30, 0.24; p<0.05), but the % stimulation does not (r2=0.02; p<0.05). These results suggest that the activity of paraoxonase is determined mainly by the genetic factor.; Summary
