Abstract

|
|
This study was carried out to obtain the basic data for the prevention of chronic poisoning by organic phosphorous pesticides and to estimate the normal range of plasma cholinesterase activity level for Korean agricultural workers.
The 285 agricultural workers were randomly selected for the study in Jungup Gun, Jeonbug Province,135 persons of them were tested in the period of pre-exposure of organophosphorous pesticides( April 1981) and rest of them were tested after exposure( August 1981).
Cholinesterase activity levels were measured by the Micro-method of Takahashi liroshi.
Major findings are as following:
1) There is significant difference in plasma cholinesterase activity levels between the pro-exposed and post-exposed group (p 0.01). Mean values of plasma cholinesterase activity levels were 7.60±1.74mM/20μl/ hr. in the pre-exposed group and 6.23±1.59mM/20ml/hr. in the post-exposed group.
2) Plasma cholinesterase activity in Korean agricultural worker could be estimated 7.30 7.90m M/ 20 mlhr. with 95% confidence interval.
