Abstract

This study was conducted to monitor the current status of pesticide residues and to calculate the correlation between monthly price fluctuation and distribution of pesticide residues in leafy vegetables at the whole market in Gyeonggi-do from 2009 to 2013. From the result, the maximum residue limit (MRL) were frequently exceeded in 5 leafy vegetables which were 48 cases of crown daisy (5.8%), 28 cases of chard (5.1%), 28 cases of spinach (3.4%), 25 cases of perilla leaves (3.4%) and 24 cases of chamnamul (3.7%). The high rate of monthly pesticide residues exceeding MRL showed on crown daisy and chard observed in June and September, spinach in October to November and December to January, perilla leaves in July to August and January, and chamnamul in August to September. To calculate the correlation between monthly price fluctuation and distribution of pesticide residues, we performed the Pearson's correlation analysis. From the results, there were significant differences between monthly price and pesticide residues detected in chamnamul, spinach and perilla leaves (p < 0.05). There were also significant differences between monthly price and pesticide residues exceeding MRL in chamnamul and crown daisy (p < 0.05). Although the small number of leafy vegetables and short period were analyzed in this study, the consolidation monitor of pesticide residues according to the season and price will be needed to acquire the safety of agricultural products.

2009년부터 2013년까지 경기지역 농산물도매시장으로 유입된 채소류에 대해 농약 잔류량을 조사한 결과 허용기준초과 빈도가 높은 5개 품목은 엽채류 중 쑥갓 48건(5.8%), 근대 28건(5.1%), 시금치 28건(3.4%), 깻잎 25건(3.4%), 참나물 24건(3.7%) 순으로 나타났다. 쑥갓과 근대는 6~9월에 높게 나타났고 시금치는 10~11월과 12~1월에 높게 나타났다. 깻잎은 7~8월 사이와 1월에 높게 나타났으며 참나물은 8~9월에 허용기준초과율이 높게 나타났다. 월별 단가와 잔류농약 검출률 간의 상간관계를 분석하고자 Pearson's correlation을 수행한 결과 참나물, 시금치, 깻잎의 경우 양의 관계(Pearson r = 0.337, 0.316, 0.297)를 나타내어 통계학적으로 유의적 차이를 나타내었다. 품목별 월별 단가와 잔류농약 허용기준초과률율 간의 상호관계를 분석하고자 Pearson's correlation을 수행한 결과 참나물, 쑥갓은 양의 관계(Pearson r = 0.259, 0.256)를 나타내어 통계학적으로 유의적 차이를 보였다(p < 0.05). 5종의 엽채류 중 참나물, 시금치, 깻잎, 쑥갓에서 월별 단가와 잔류농약 검출률 또는 허용기준초과율 중 한 가지 이상에서 상관관계를 나타내었다. 향후 월별 단가와 농약 잔류에 대한 전국단위의 연구조사가 필요할 것으로 판단되며 잔류농약 허용기준초과 빈도를 저감화하기 위해서는 각각 농산물에 대한 농약 안전사용기준 준수와 수확 전 농약 사용 금지 기간을 준수하여야 할 것으로 판단되었다.
