A Study on Parasitic Eggs in Soil in Rural Area

一部 農村地域의 寄生蟲卵 土壤 汚染度에 관한 調査硏究

Going to the studies on parasite control carried out in the past. Infection rate among the rural population is contineously decreasing, however, it is still high in Korea. The most important reason for this high infectious rate is the use of manure as fertilizer. This study was aimed at finding the relationship between the infection rate and manure through analizing 83 samples of soil collected from Sa Am-Ri, Kangwon-do in June and July, 1983. The major findings of the study are as follows: 1. 60 cases out of the total sample were carry in at least one or more parasitic eggs, thus revealing 72.3% of positive rate. 2. A total number of 131 parasitic eggs were detected from total sample with an average of 1.6 eggs per 10 g of soil. 3. Asearid eggs more frequently appeared than other parasitic eggs occupying 68.7% or 1.2 eggs in average per 10g of soil. 4. There was revealed positive relationship between infectious rate and frequency of use of manure. (P > 0.05). 5. Infectious rate and average number of parasitic eggs detected were less in the fertilizer mixed with manure and ash than in the soil where only manure was used. (P > 0.05).
