현재의 농업에서 농약의 사용은 불가결한 것이다. DDT의 등장으로 농약만능시대의 막이 열린 이래 세계에서 10만종 이사의 농약이 탄생했다. 현재 전세계의 생산량은 매년 1천만 톤을 넘어섰고 일본의 경우 등록되어 있는 농약수는 원체(화합물종류)로서 367종, 상품명으로서는 약 5800 종류가 판매되고 있다. 년간 일본의 농약생산량은 약 60만 톤으로 농약의 수출량과 수입량이 거의 같기 때문에 생산량이 사용량에 상당하는 것으로 본다. 농약의 식품오염의 측면에서 보면, 단위 면적당 세계 제 1위의 농약 사용국인 일본은 시장에 유통되고 있는 농작물에도 상당한 양의 농약이 잔류하는 것으로 본다. 물론 식품위생법에 26종의 농약에 대해 53작물을 대상으로 하는 잔류농약기준이 있지만, 농약성분이 400종 이상이며 산포 대상이 되는 작물은 53작물보다 훨씬 많다. 또한 한 두 종류의 작물밖에 대상이 되지 않는 농약도 많아서 잔류농약기준은 식품의 안전성 확보면에서는 부족한 것이 많아. 따라서 농산물 생산자 스스로가 농약사용기준을 정확하게 지켜주기를 바랄 뿐이다. 한편으로는, 이러한 현실에 비추어서 농약사용이 일상화된 농업자에게 있어 농약으로 인한 건강상의 문제 또한 적지 않다. 농업자의 건강관리 대책의 일환으로 실시하는 건강진단 및 조사에 따르면, 만성적인 질환뿐만 아니라 농약산포작업후에 나타나는 증세(기침, 피부이상, 불쾌감, 두통, 인후염, 구토)를 경험한 작업자는 예방의학적인 견지에서 농업자의 농약폭로실태파악 및 교육을 해오고 있으나 그다지 설득력을 얻지 못하여 보다 확실한 인체내 흡수량을 측정하는 방법을 생각하게 되었다. 즉 뇨중 농약 대사물을 폭로지표로 하는 생물학적 모니터링(biological monitoring)을 시도, 농업현장에 있어서의 그 실증과 유용성에 대한 검토를 하고자 하였다. 농작업 가운데서 가장 위험하다고 보는 농약산포작업 (수동식 분무기를 이용한 하우스작물 및 동력분무기를 사용한 노지작물)을 대상으로 생물학적모니터링을 실시한 결과 업자의 뇨로부터 농약의 체내흡수를 반영하는 농략의 뇨 분비성 대사물을 측정할 수 있었다. 즉 뇨나 혈액등의 생체시료를 이용한 생물학적모니터링의 농약에의 응용은 서구와는 달리 대부분이 규제가 없는 소규모 자가영농으로 정해진 농약사용지침보다 많은 농약을 사용한다거나, 또는 개인의 습관이나 작업환경에 따라 폭로조건이 달라서 실질적인 폭로-흡수의 정도가 불분명한 경우등에도 충분히 대응할 수 있어 농약사용자 개개인의 농약 폭로-흡수의 정도를 분명하게 밝힐 수 있다. 게다가 평가의 결과를 농약사용의 일선에 있는 농업자에게 피드백 하여 주므로서 농약에 대한 인식을 새롭게 하고 농약취급시의 건강장해예방행동을 촉구하는 등의 효과도 높은 것으로 예방의학적인 유용성이 크다고 볼 수 있다.

We tested for residual pesticide levels in school foodservice agricultural products in Seoul, Korea from 2010 to 2012. A total of 316 samples of 23 different types of agricultural products were analyzed via gas chromatography-nitrogen phosphate detector (GC-NPD), an electron capture detector (GC-${\mu}ECD$), a mass spectrometry detector (GC-MSD), and a high performance liquid chromatography-ultraviolet detector (HPLC-UV). We used multi-analysis methods to analyze 185 different pesticide types. Among the selected agricultural products, residual pesticides were detected in 26 samples (8.2%), of which 6 samples (1.9%) exceeded the Korea Maximum Residue limits (MRLs). We detected pesticide residue in more than 65% of the Chwinamul, while 6 among 9 analyzed samples contained pesticide residue, and 1 sample exceeded the Korea MRLs. Among the 185 kinds of pesticides that we have tested, 18 were detected, while 7 of them were detected more than twice. Data obtained were then used for estimating the potential health risks associated with the exposures to these pesticides. The most critical commodity is carbofuran in the perilla leaves, which has contributed 3.8% to the hazard index (HI). These results showed that the detected pesticides could not be considered as a serious public health problem. Nevertheless, constant supervision is recommended.

"안전한 작물보호제"라는 말이 있다. 그렇다면 "안전"이란 어떠한 성질을 말하는 것일까. 신문 등에 과거 DDT의 이야기가 실릴 때에는 "독성이 강한 농약 DDT${\cdots}$"등과 같이 "독성이 강한"이라는 표현을 붙이는 경우가 많다. "독성이 강하다"라는 것은 어떠한 성질을 말하는 것일까. 올해 전, 모 신문은 '식염수를 마시고 사망한 소녀의 이야기"를 전했다. 구내염(口內炎)으로 아파하는 소녀에게 부모가 식염수로 양치를 시키자 더욱 괴로워했다. 그래서 엄하게 꾸짖으며 억지로 마시게 했더니, 염분의 농도가 짙어서 사망했다고 한다. 식염은 과연 "독성이 강한"것일까. 쉽게 사용해서는 안 되는 "안전"이나 "독성"이란 말은 어떤 의미를 갖는 것일까. 먼저 작보제에 대해서 약간의 문제점을 정리해보기로 하겠다. 그리고 작보제 안전성에 대해서 구체적이고 정석적인 이야기보다는 기본적인 개념을 주로 다루어 보고자 한다.

The data on pesticide poisoning death toll during 2000-2005 was obtained from Korean National Statistical Office and analysed to find out any precautionary measures against pesticide poisonings. Pesticide poisoning death toll showed slightly increasing trend with year up to about 3500 in 2005. Most of the pesticide poisoning death cases were intentional self-poisoning accounting for more than 80% of total pesticide poisoning death. The pesticide most often implicated in poisoning death were paraquat dichloride, a non-selective herbicide and organophosphate/carbamate insecticides. The regional distribution of pesticide poisoning death showed urban 21.6% and rural area 78.4%. As for the occupation of the dead, agricultural, forestry and fishery workers accounted for 27.4% and non-agricultural workers was 72.6% of pesticide poisoning death. Therefore, government need to take some precautionary measures to reduce the number of pesticide poisoning cases. It is strongly recommended that pesticide regulatory authorities encourage and train the agricultural workers to use safe storage boxes and enforce strict regulation for the prevention for the prevention of highly toxic pesticides sales to non-agricultural workers.

Purpose : The aim of this research was to clarify the difference in awareness of food safety and what they feel as dangerous among parents in Japan, China, and Korea and how they are different among the nations. Methods : Research subjects were 250 parents in Japan, 181 parents in China, 166 parents in Korea whose children attend a child institution or a day care center. We conducted a questionnaire survey that was self-written and anonymous. Results : Parents in Japan feel safer than Korea and China, and parents in Korea feel safer than China about food that are sold generally. Especially, in China, the average of 5 level scale was lower than the median so it shows that people do not trust food that are sold in the market. All 3 countries tend to have the awareness that "pesticide that is over the standard amount is detected from vegetables in China" and "vegetable grown without pesticides and organic produce are safe" and showed no significant difference. Also, there was a significant difference statistically for the awareness that "it makes it easier to get cancer if you eat food that contain radiation" and "there is a possibility that seafood caught near Japan contain radiation". Parents in Japan emphasize that "the price is low" the most and it was significantly higher than in China and Korea. Also, similar to parents in Japan, parents in Korea tend to emphasize that it is "domestic". On the other hand, it verified that parents in China emphasized "the meat or fish is grown without antibiotics" and "it uses vegetable grown without pesticides".

This study investigated pesticide residues in 7,069 agricultural products distributed in the city of Incheon from 2019 to 2021. Ingestion of pesticides can cause serious carcinogenic, endocrine, neurological, and reproductive problems. Pesticide residues in the samples were analyzed using various multi-residue methods (GC-MS/MS, GC-ECD/NPD, LC-MS/MS, and HPLC-UVD) on the Korean Food Code. The violation rate of the samples exceeding the maximum residue level (MRL) of pesticide residues for the years 2019, 2020, and 2021 was 1.0%, 1.4%, and 1.1%, respectively. Diazinon, flubendiamide, procymidone, fluxametamide, and fluquinconazole were the most frequently reported violative pesticide residues. Most commonly encountered agricultural products exceeding MRLs were coriander leaves, chamnamul, chwinamul, welsh onion, and crown daisy. Agricultural products and pesticides frequently exceeding MRLs should be continuously inspected for food safety. Continuous monitoring of pesticide residues in agricultural products is indispensable to improve consumer safety by preventing the distribution of agricultural products exceeding MRLs.

Objectives: The purpose of this study was to measure the symptom prevalence of acute pesticide poisoning among farmers in Gyeong-gi province and to investigate the occupational risk factors. Methods: The subjects were 663 farmers using pesticide directly or indirectly and the survey was performed during 2013. 7. 11 - 2014. 8. 27. The data were analyzed by SPSS 21.0. Results: The prevalence of acute pesticide poisoning was 6.63% and dizziness was the most common symptom. Acute pesticide poisoning was related with 'days of pesticide use per year', 'lifetime pesticide application days', 'the number of pesticide mixture' and 'type of farming'. Conclusions: It is necessary to manage and educate the pesticide poisoning-vulnerable group more systematically. Afterward additional study is needed to investigate the farming safety behavior and delicate amount of pesticide exposure.

Ginseng has a unique production system that is different from those used for other crops. It is subject to the Ginseng Industry Act., requires a long-term cultivation period of 4-6 years, involves complicated cultivation characteristics whereby ginseng is not produced in a single location, and many ginseng farmers engage in mixed-farming. Therefore, to bring the production of Ginseng in line with GAP standards, it is necessary to better understand the on-site practices of Ginseng farmers according to established control points, and to provide a proper action plan for improving efficiency. Among ginseng farmers in Korea who applied for GAP certification, 77.6% obtained it, which is lower than the 94.1% of farmers who obtained certification for other products. 13.7% of the applicants were judged to be unsuitable during document review due to their use of unregistered pesticides and soil heavy metals. Another 8.7% of applicants failed to obtain certification due to inadequate management results. This is a considerably higher rate of failure than the 5.3% incompatibility of document inspection and 0.6% incompatibility of on-site inspection, which suggests that it is relatively more difficult to obtain GAP certification for ginseng farming than for other crops. Ginseng farmers were given an average of 2.65 points out of 10 essential control points and a total 72 control points, which was slightly lower than the 2.81 points obtained for other crops. In particular, ginseng farmers were given an average of 1.96 points in the evaluation of compliance with the safe use standards for pesticides, which was much lower than the average of 2.95 points for other crops. Therefore, it is necessary to train ginseng farmers to comply with the safe use of pesticides. In the other essential control points, the ginseng farmers were rated at an average of 2.33 points, lower than the 2.58 points given for other crops. Several other areas of compliance in which the ginseng farmers also rated low in comparison to other crops were found. These inclued record keeping over 1 year, record of pesticide use, pesticide storages, posts harvest storage management, hand washing before and after work, hygiene related to work clothing, training of workers safety and hygiene, and written plan of hazard management. Also, among the total 72 control points, there are 12 control points (10 required, 2 recommended) that do not apply to ginseng. Therefore, it is considered inappropriate to conduct an effective evaluation of the ginseng production process based on the existing certification standards. In conclusion, differentiated certification standards are needed to expand GAP certification for ginseng farmers, and it is also necessary to develop programs that can be implemented in a more systematic and field-oriented manner to provide the farmers with proper GAP management education.

최근 안전한 먹거리 생산과 치유, 교육 등 다양한 목적으로 도시농업에 참여하는 인구가 늘어남에 따라 도시텃밭의 농약, 비료 사용 등으로 인한 환경오염과 해충 피해, 농산물의 건강성 등 다양한 문제가 제기되고 있다. 따라서 도시텃밭 작물의 생육 증진, 잔류농약 문제 해결 등 농산물 안정성 증가에 기여하고자 식물추출물을 활용한 엇갈이 배추의 생육특성을 조사하였다. 선행연구 결과를 바탕으로 자원식물류 5종(쇠비름, 소리쟁이, 명아주, 박주가리, 환삼덩굴)과 허브류 5종(메리골드, 서던우드, 캐모마일, 애플민트, 로즈마리), 식용작물류 5종(양파, 마늘, 부추, 차즈기, 들깨) 등 추출 대상 식물 15종을 60℃에서 3일간 건조시켜 마쇄하였다. 이후 각 식물체 100g을 35% 에틸알코올 1,000ml에서 7일간 추출하였다. 추출물은 30%로 희석하여 주 2회씩 총 3주간 배추에 엽면살포하였다. 엽면적, 엽수, 지상부 및 지하부 생체중 등 생육특성을 7일 간격으로 조사하였으며 그 결과는 다음과 같다. 엽면적과 엽폭은 환삼덩굴 처리구에서 104.58cm²와 9.80cm로 가장 넓었고, 엽장은 박주가리 처리구에서 25.24cm로 가장 길었으며, 지하부 생체중은 메리골드 처리구에서 6.24g으로 가장 높았다. 엽수는 애플민트와 마늘 처리구에서 6.4개로 가장 많았고, 지상부 생체중과 엽록소는 집단 간 유의한 차이가 나타나지 않았다. 전반적으로 무처리 대비 엽면적 22%, 엽폭 18%의 유의한 생장 차이를 보인 환삼덩굴 추출물과 엽면적 12%, 엽장 17%의 생장 차이를 보인 박주가리 추출물, 엽면적 10%, 엽폭 9%의 생장 차이를 보인 양파 추출물이 엇갈이 배추 생육에 효과적인 것으로 나타났다. 본 연구결과 환삼덩굴, 박주가리, 양파 등 일부 식물추출물이 엇갈이 배추의 생육을 증진시킬 수 있는 것으로 나타나 주말농장 등 도시텃밭에 활용할 수 있을 것으로 사료되었다. 향후 식물추출물의 효과성을 증진시키기 위해 추출 방법과 적정 농도, 보관 시기 등에 대한 연구와 함께 도시텃밭 해충방제 효과를 알아보기 위한 약해검정과 살충효과를 분석할 필요성이 있다.
