  • Recently, golf courses have increased over the years because golf became popular leisure sport. Various environmental problems have been then issued by a golf course during constructing and running them. A problem of pesticide, which is serious among various environmental problems, from golf course has harmful effect on surrounding area and makes human suffer from acute and chronic diseases. Pesticides are used for the cost-effective managing of golf course and the amount of pesticides also increases as the number of golf course increase. Since the assessment of pesticides on near-by surrounding has been focused on water and soil media, studies related to atmospheric dispersion have been hardly attempted. The method to assess an impact of pesticide nearby agricultural production by the atmospheric dispersion using AGDISP(AGricultural DISPersal) model was developed and applied to the actual planned golf course located in Hongcheon, Gangwon. For implementing AGDISP, parameters were investigated from the golf course's land use planning map, pesticide spray device, Hong-Cheon weather station and etc. First of all, a kind of pesticide, a form of spraying pesticide, geographical features, weather data, and distance(golf course to plantation) were investigated to understand how to work these parameters in AGDISP. Restricted data(slope angle, droplet size distribution and solar insolation) sensitivity analysis of these parameters to estimate effect of pesticide nearby a plantation and a high relative contribution data of analyzed data was selected for input data. Ethoprophos was chosen as the pesticide used in the golf course and the amounts of pesticide deposition per annual agricultural productions were predicted. The results show that maximum amount of pesticide deposition through atmospheric dispersion was predicted $2.32{\mu}/m^2$ at 96 m where the nearest organic plantation exists. The residues of pesticide were also estimated based on the annul production of the organic and the deposition amount of the pesticide. Consequently, buckwheat, wheat and millet were likely to exceed maximum residue limits for pesticides in foods(MRL) and sorghum, corn and peanut were likely to exceed MRL by organic farming as well.

  • Objectives: This study aims to examine patients who developed acute pesticide poisoning while spraying or using pesticide and presented to the emergency department in hospitals in Chungcheongnam-do Province. Based on the findings, this study will provide implications for safety and health management pertaining to the use of pesticides. Methods: Pesticide poisoning data collected by the Chungnam Center for Farmers' Safety and Health from 2014 to 2018 was cross-sectionally analyzed. A total of 331 patients with pesticide poisoning presented to one of hospitals and four of medical centers in the region(Dankuk University Hospital, Gongju and Hongsung, Cheongyang, Cheonan Medical Center). Seventeen of these patients (15 men and two women) developed poisoning while spraying pesticide. The patients' charts were reviewed to collect data on pesticide poisoning, namely currently working in farming-related occupation, means of transportation to the hospital, place of poisoning, symptoms of acute pesticide poisoning, treatment, pesticide used when poisoning occurred, and classification by technical ingredients. Results: Fifteen out of 17 patients who developed poisoning while spraying pesticide were men. Insecticide was used in 35.3% of the cases, and herbicide was used in 29.4% of the cases, which was different from cases of poisoning from ingestion poisoning. The major symptoms were vomiting (35.3%), nausea (29.4%), dizziness (29.4%), and headache (23.5%). A total 11 ingredients were identified in 12 patients, and the most common ingredient was glyphosate, which is an herbicide. Most patients showed a state of mild toxicity, but two patients showed a state of severe toxicity. These patients respectively used glyphosate and paraquat. Conclusions: Our findings can be useful for suggesting the need for a national healthcare system to manage occupational pesticide poisoning among farmers. Further, these findings can be used to increase the awareness of the risk of acute poisoning during pesticide spraying and suggest the need for a safety health education to increase farmers' awareness of pesticide poisoning.

  • This study was conducted to investigate the residue amount of pesticide on the 41 medicinal herbs in Daejeon area. This study was carried out to monitor the current status of pesticide residues in commercial medicinal herbs for sale of food use in 2012. It was performed using GC/ECD, GC/NPD, HPLC to analyze pesticides residues. Residues of 283 pesticides were analyzed by a simultaneous multiresidue method in 41 medicinal herbs being on sale in Daejeon. The medicinal herbs detected pesticides in 10 of 41 cases, showed a detection rate of 24.39%. The medicinal herbs which exceed the maximum residue limit were five cases as Cnidii Rhizoma, Osterici Radix, Artemisiae Capillaris Herba, Zizyphi Fructus and Alismatis Rhizoma. And pesticide residue of Cnidii Rhizoma and Alismatis Rhizoma exceeds the limit standard presented in only medicine use of KFDA. The residual pesticides which had the high detection rate were Chlopyrifos, Tebuconazole and Endosulfan in the detection of medicinal herbs. For further research, standards of Pesticide Residues in medicinal herbs should be added and more research of pesticide residues in medicinal herbs required. And standards of pesticide residues in medicinal herbs should be applied equally as medicines and food.

  • Although pesticides have increased crop production and controlled disease, they have produced a number of adverse health effects. Pesticides have potential human toxicity and a variety of groups, such as farmers or industrial workers, as well as the general population, are exposed to pesticides. The purpose of this article, therefore, is to provide an overview of pesticide exposure and health through a literature review, focusing on exposure assessment, acute poisoning, chronic health effects, and future research needs. The exposure types and levels of pesticides vary by study subjects and need to be assessed by integrating several methods focused on the epidemiological purpose. Acute pesticide poisoning is a major public health problem in the world. Paraquat is the main causative pesticide for acute poisoning in Korea and should be banned in order to save several thousands of lives every year. Occupational pesticide exposure also causes numerous chronic diseases among farmers and industrial workers, including cancers, respiratory diseases, depression, retinal degeneration, diabetes, and abnormal menstrual cycle. However, controversy exists regarding the long-term effects of low-dose environmental pesticide exposure. The area of pesticide study is relatively new with broad study populations and it has received little academic and policy attention, particularly in Korea. More detailed studies investigating the risk of pesticide-related health effects and intervention efforts to reduce the problems are needed in Korea.

  • Background: Occupational end users of pesticides may experience bodily absorption of the pesticide products they use, risking possible health effects. The purpose of this paper is to provide a guide for researchers, practitioners, and policy makers working in the field of agricultural health or other areas where occupational end use of pesticides and exposure issues are of interest. Methods: This paper characterizes the health effects of pesticide exposure, jobs associated with pesticide use, pesticide-related tasks, absorption of pesticides through the skin, and the use of personal protective equipment (PPE) for reducing exposure. Conclusions: Although international and national efforts to reduce pesticide exposure through regulatory means should continue, it is difficult in the agricultural sector to implement engineering or system controls. It is clear that use of PPE does reduce dermal pesticide exposure but compliance among the majority of occupationally exposed pesticide end users appears to be poor. More research is needed on higher-order controls to reduce pesticide exposure and to understand the reasons for poor compliance with PPE and identify effective training methods.

  • Water quality contamination issues are of critical concern to human health, whilst pesticide release generated from irrigated land should be considered for protecting natural habitats and human health. This paper suggests new method for evaluation and analysis using the GIS technique based on integrated spatial modeling framework. The pesticide use on irrigated land is a subset of the larger spectrum of industrial chemicals used in modern society. The behavior of a pesticide is affected by the natural affinity of the chemical for one of four environmental compartments; solid matter, liquid, gaseous form, and biota. However, the major movements are a physical transport over the ground surface by rainfall-runoff and irrigation-runoff. The irrigated water carries out with the transporting sediments and makes contaminated water by pesticide. This paper focuses on risk impact identification and assessment using GIS technique. Also, generated data on pesticide residues on farmland and surface water through GIS simulation will be reflected to environmental research programs. Finally, this study indicates that GIS application is a beneficial tool for spatial pesticide impact analysis as well as environmental risk assessment.

  • Objective: This study aimed to test the accuracy of self-reported information used in indirect estimation of pesticide exposure. Methods: To do so, self-reported values on the duration of pesticide application per day were compared with observed values. The number of days of pesticide application per year as recorded in self-administered logs was compared with recalled values. Results: It was found that participants underestimated the duration and frequency of actual pesticide use. High correlations were found between self-reported values and observed values, as well as between recalled values and recorded values. Conclusions: The reason might be that farmers unconsciously under-recall the application of pesticide since many customers prefer eco-friendly agricultural products. Farmers thought the task of applying pesticides to be essential, and this may explain why the participants in this study tended to accurately recall their pesticide-related work.

  • 우리나라에서 가장 널리 재배되는 토마토 과종인 방울토마토와 완숙토마토를 시설하우스에서 재배하여 두 과종 간에 비표면적을 측정하였으며, 농약의 잔류량을 분석하여 비표면적과 농약 잔류량과의 상관 관계를 조사하였다. 완숙된 토마토의 비표면적은 방울토마토가 $2.15cm^2g^{-1}$, 완숙토마토가 $1.00cm^2g^{-1}$로써 방울토마토의 비표면적이 약 2배 더 컸다. 농약의 물리화학적 성질과 제형이 다른 4종의 농약(타로닐 수화제, 크로로타로닐 액상수화제, 옥사딕실 쿠퍼 수화제, 지오판 수화제)을 선발하여 농약 잔류량을 측정한 결과, 방울토마토의 농약 잔류량이 완숙토마토보다 살포일수 및 살포횟수에 관계없이 $1.4\sim2.4$배 정도 많이 잔류되었다. 이러한 결과로 토마토 과종간의 비표면적의 비와 농약 잔류량이 상관성이 있는 것으로 확인되었으며, 농약살포 후 최종 수확 때까지 토마토의 비대생장이 없었기 때문에 농약 잔류량은 비표면적이 주된 인자로 작용한 것으로 보인다.

  • Background: Sister chromatid exchange (SCE) in human peripheral blood lymphocytes is one of the most extensively studied biomarkers employed to evaluate genetic damage subsequent to pesticide exposure. Objective: To estimate the pooled levels of SCE in human peripheral blood lymphocytes among population exposed to pesticide. Materials and Methods: Meta-analysis on the association between SCE frequency and pesticide exposure was performed with STATA 10.0 software package and Review Manager 5.0.24 in this study. Results: The overall means of SCE were 7.88 [95% confidence intervals (95%CI): 6.71-9.04] for exposure group and 6.05 (95%CI: 5.13-6.95) for controls, respectively. There was statistically significant difference in the SCE frequency in human peripheral blood lymphocytes between pesticide-exposed groups and control groups, and the summary estimate of weighted mean difference was 1.69 (95%CI: 1.01-2.38). We also observed that pesticide-exposed population had significantly higher SCE frequency than control groups among smokers, nonsmokers, pesticide applicator, pesticide producer, other exposure population and Asian population in stratified analyses. Conclusions: Data indicate that the SCE frequency in human peripheral blood lymphocytes might be an indicator of early genetic esffects for pesticide-exposed populations.
