“…Endosulfan (total) is the non-systemic agrochemical and has been known to be mainly present within 10 cm in depth of soil layer [27,28] with its value of Koc of 7100~12,100 to soil that corresponds to the non-mobile class (Koc > 4000) in the standard of classification of mobility specified by the SSLRC (Soil Survey and Land Research Center, Cranfield, UK). It also corresponds to the immobile class (Koc > 5000) in the standard of classification of mobility specified according to values of Koc by McCall, Swann, Laskowski, Unger, Vrona, and Dishburger [29] which is typically regarded as one of the most immobile agrochemicals [28]. Therefore, by the low immobility of endosulfan (total) owing to its high adsorption to soil [28,30,31], the probability of direct translocation of endosulfan (total) to crops would be low.…”

However, according to previous studies examined the translocation of endosuflan in soil to crops, the cases of translocation of endosulfan to crops were reported [14,27,32].…”

This study was conducted to examine the translocation of highly residual agrochemical in soil, the endosulfan (total), to ginseng (Panax ginseng C. A. Meyer). The soil with the level of the amount of 5.0 mg kg −1 of endosulfan (total) was prepared in a Wagner pot into which the seedling of ginseng was transplanted and then the specimens of ginseng (root, leaf, and stem) were collected quarterly and analyzed through GC-MS. The level of residual of endosulfan (total) in the soil has decreased from 4.28 mg kg −1 (April 2013) to 1.94 mg kg −1 (December 2014) while the level in the specimens of leaf and stem of ginseng respectively sampled according to its growth phase in June and September from 2013 and 2014 showed an increase from 0.56 mg kg −1 (June 2013) to 2.46 mg kg −1 (September 2013) and decrease from 0.29 mg kg −1 (June 2014) to 0.18 mg kg −1 (September 2014). For the case of the root of ginseng, the level of the amount of 10.77 mg kg −1 of endosulfan (total) was detected in June 2013 and then, the level has decreased to the level of 4.88 mg kg −1 in December 2014. The translocation of residual endosulfan (total) in soil to ginseng with time was identified. The amount of residuals of α-endosulfan and β-endosulfan was also decreased with time however, the ratio of endosulfan-sulfate, the main metabolite, was gradually increasing. The retention of metabolite (endosulfan-sulfate) in soil identified thereby thus suggests the potential of its translocation to plants in the case of the soils containing the residual of endosulfan (total).

“…우리나라에서는 시설재배 작물을 제외한 대부분의 밭작물 이 경사지에서 재배되고 6~9월 사이에 강우 집중시기와 농 약 사용시기가 겹쳐지게 되므로 집중강우에 의하여 농약이 수계로 유출될 가능성이 높을 것으로 예상된다. 그러나 농 약에 의한 수계오염의 중요한 경로인 표면유출에 대한 연구 결과는 국내의 경우 소수 (Moon et al, 1993;Kim et al, 1997;Kim et al, 2006) (Kim et al, 2007).…”

The field lysimeter study was undertaken to investigate influence of agricultural practice and topography on runoff and erosion loss of fluazinam from the sloped land grown pepper. The WP type formulation was applied on July in 2003~2005. The wash-off rates were from 1.4% to 8.4% of the applied fluazinam. The runoff losses of fluazinam from a series of pepper grown-lysimeter plots were 0.14~0.90% in the first year, 0.01~0.04% in the second year and 0.16~0.37% in the third year for the mulched contour ridge plots, 0.47~1.59% for the mulched up-down direction ridge plots and 0.07~1.05% for the no-mulched contour ridge plots as the control, and they increased with slope degree. Concentrations of fluazinam in runoff water ranged mostly to 10 µg L − 1 at the first runoff event. Erosion rates from plots except the mulched up-down direction ridge plots was 0.00~0.21% for 10% and 20% slope-plots and 0.15~1.05% for 30% slope-plots with different slope degrees. Erosion rates from the mulched up-down direction ridge plots were 0.47~1.59% for 10% slope-plots and 0.75~1.05% for 20% slope-plots. Residues of fluazinam in soil at ten days after the application ranged from 0.007 mg kg

BACKGROUND:To evaluate residues of environmentally concerned pesticides in water system, this monitoring was conducted over three rivers. The residual characteristics and discharging condition of these residues on water system was investigated. METHODS AND RESULTS: Total twenty nine sampling sites were selected through main streams and branch streams of Keum, Mangyung and Dongjin rivers, and the water samples from them were regularly collected one month interval, especially biweekly from May to August in 2002. Of the pesticides monitored, six fungicides which include hexaconazole, isoprothiolane and iprobenfos were detected with frequencies of 0.3-50.9% and in their residue level of 0.1-4.7 g/L. Sixteen insecticides which include μ nine organophosphoruses, three carbamates, endosulfan, cypermethrin, buprofezin and fipronil were detected with frequencies of 0.3-32.5% and in their residue level of 0.01-2.8 g/L. Nine herbicides which include alachlor μ molinate, anilofos, butachlor, dimepiperate, metolachlor, oxadiazon, pretilachlor and thiobencarb were detected with frequencies of 0.8-22.9% and in their residue level of 0.01-9.07 g/L. μ CONCLUSION: Detection frequencies and residue levels of insecticides and herbicides were the highest in waters sampled in May and June. Almost pesticides detected were for the paddy rice and their residue levels were very low to compare with standard values.
