  • Background: Ammonia and hydrogen sulfide are harmful gases generated during aerobic/anaerobic bacterial decomposition of livestock manure. We evaluated ammonia and hydrogen sulfide concentrations generated from workplaces at livestock farms and determined environmental factors influencing the gas concentrations. Methods: Five commercial swine farms and five poultry farms were selected for monitoring. Real-time monitors were used to measure the ammonia and hydrogen sulfide concentrations and environmental conditions during the manure-handling processes. Monitoring was conducted in the manure storage facility and composting facility. Information on the farm conditions was also collected through interview and walk-through survey. Results: The ammonia concentrations were significantly higher at the swine composting facilities (9.5-43.2 ppm) than at other manure-handling facilities at the swine and poultry farms, and high concentrations of hydrogen sulfide were identified during the manure agitation and mixing process at the swine manure storage facilities (6.9-19.5 ppm). At the poultry manure-handling facilities, the ammonia concentration was higher during the manure-handling processes (2.6-57.9 ppm), and very low hydrogen sulfide concentrations (0-3.4 ppm) were detected. The air temperature and relative humidity, volume of the facility, duration of manure storage, and the number of animals influenced the gas concentrations. Conclusion: A high level of hazardous gases was generated during manure handling, and some levels increased up to risk levels that can threaten workers' health and safety. Some of the farm operational factors were also found to influence the gas levels. By controlling and improving these factors, it would be possible to protect workers' safety and health from occupational risks.

  • Background: Occupational hazards in crop farms vary diversely based on different field operations as soil management, harvesting processes, pesticide, or fertilizer application. We aimed at evaluating the immunological status of crop farmers, as limited systematic investigations on immune alteration involved with crop farming have been reported yet. Methods: Immunological parameters including plasma immunoglobulin level, major peripheral immune cells distribution, and level of cytokine production from activated T cell were conducted. Nineteen grape orchard, 48 onion open-field, and 21 rose greenhouse farmers were participated. Results: Significantly low proportion of natural killer (NK) cell, a core cell for innate immunity, was revealed in the grape farmers (19.8±3.3%) in comparison to the onion farmers (26.4±3.1%) and the rose farmers (26.9±2.5%), whereas cytotoxic T lymphocyte proportion was lower in the grape and the onion farmers than the rose farmers. The proportion of NKT cell, an immune cell implicated with allergic response, was significantly higher in the grape (2.3±0.3%) and the onion (1.6±0.8%) farmers compared with the rose farmers (1.0±0.4%). A significantly decreased interferon-gamma:interleukin-13 ratio was observed from ex vivo stimulated peripheral blood mononuclear cells of grape farmers compared with the other two groups. The grape farmers revealed the lowest levels of plasma IgG1 and IgG4, and their plasma IgE level was not significantly different from that of the onion or the rose farmers. Conclusion: Our finding suggests the high vulnerability of workplace-mediated allergic immunity in grape orchard farmers followed by open-field onion farmers and then the rose greenhouse farmers.

  • 본 연구는 취나물, 고춧잎, 열무를 대상으로 건조에 따른 procymidone, diazinon의 잔류량의 경시적 변화를 연구할 목적으로 수행되었다. 실내풍건 방법으로 건조하는 경우, procymidone, diazinon의 잔류량이 증가하지만 수분함량의 감량을 고려하여 보정하면 $10{\sim}83%$ 감소하였고, 열풍건조 방법으로 건조하는 경우도 농약 잔류량은 증가하여도 수분함량의 감량을 고려하여 보정하면 $44{\sim}71%$ 감소하였다. 이 결과에 의하면, 건조에 의하여, 수분 보정한 농약잔류량이 대부분 감소하므로 건조농산물을 판정함에 있어 단순히 신선농산물의 기준에서 수분함량의 감량을 고려하여 기준 적용할 것이 아니라 건조과정 중 농약잔류량에 영향을 미치는 여러 요인을 고려한 추가연구가 필요하다고 판단된다.

  • BACKGROUND: Increase of heavy metals in agricultural ecosystem has become a social issue nationwide as it is related to public health. This review was performed to find out more systematic and integrated future researches on heavy metals using up to date articles published in the Korean journals related to agricultural environment. METHODS AND RESULTS: Researches on heavy metals in agricultural soils and plant uptake were categorized by the establishment of criteria, analytical methods, monitoring, management of source, characteristics and behavior in soil, plant uptake, bioavailability affecting physico -chemical properties in soil, risk assessment and soil remediation. In the early 1990s, the monitoring for heavy metals in soil has been widely performed. Accumulation of heavy metals in contaminated soil and availability to plants has also attracted interests to study the soil remediation using various physico-chemical methods. The phytoavailability and phytotoxicity of heavy metals have been mainly studied to assess the safety of agro-products using risk assessment techniques in the 2000s. CONCLUSION: Future direction of research on heavy metal in agricultural environment must be carried out by ensuring food safety and sustainability. A steady survey and proper management for polluted regions should be continued. Law and regulation must be modified systematically. Furthermore, studies should expand on mitigation of heavy metal uptake by crops and remediation of polluted fields.

  • 현재까지 한국 벌화분 잔류농약 함량 조사는 벌이 농약에 노출된 정도를 파악하기 위한 목적으로 분석되어 왔고, 식품의 관점에서 벌화분의 잔류농약 함량 연구는 보고된 바 없었다. 본 연구는 화분가공품으로서 식용으로 판매되는 벌화분 제품의 잔류농약 함량 모니터링을 통해 한국에서 유통되는 벌화분에서 잔류농약이 얼마나 검출되는지를 파악하였다. 조사 결과 다양한 농약 성분들이 벌화분에 잔류되어 있었고, 그 중에서 Chlorfenvinphos, Chlorpyrifos 같이 식용작물에서 사용금지된 농약들이 포함되어 있었다. 벌의 활동범위는 식용작물에 국한되어 있지 않기 때문에, 식용작물에만 제한적 농약사용 등의 인위적 관리만으로는 식용 벌화분의 유해물질로부터 안전성을 확보하는 것이 불가능하다는 것을 파악할 수 있었다. 따라서, 식용 벌화분의 잔류농약 안전성에 대한 연구 및 기준 설정이 필요할 것으로 보인다. 또한, 벌화분 원료와 완제품의 성상적 차이가 미미하고 주로 완제품 형태로 유통된다는 것을 고려하였을 때, 원료에만 기준을 두어 잔류농약 검사를 하는 것이 아니라 벌화분의 완제품에서도 잔류농약 검사가 필요할 것으로 보인다.

  • 인천광역시에서 유통 중인 농산물을 대상으로 2019년부터 2021년까지 최근 3년간 잔류농약 모니터링을 실시한 결과 총 7,069건 중 83건(1.2%)이 잔류허용기준을 초과하였다. 농약 잔류허용기준을 초과한 부적합 농산물의 비율은 1.0%, 1.4%, 1.1%으로 매년 유사한 수준으로 나타났으며 잔류농약 검출율은 8.2%, 8.4%, 7.4%를 보였다. 최근 3년간 diazinon, flubendiamide, procymidone, fluxametamide, fluquinconazole, hexaconazole 등의 순서로 부적합 검출빈도가 높았으며 농산물 분류별로는 전체 농산물 중 엽채류와 허브류에서 매년 83% 이상 발생하였다. 부적합 발생빈도가 높았던 농산물은 고수(잎), 참나물, 취나물, 파 등이었으며 고수(잎)은 3년 연속으로 부적합 건수가 가장 많았다. 농산물 생산지역별로는 경기, 인천, 충남, 전남 순으로 부적합 건수가 많았으나 지역별 출하 농산물의 검사건수 대비 부적합율은 1.5% 내외로 큰 차이는 없었다. 일부 농산물에서 농약 잔류허용기준의 최대 250배까지 잔류농약이 검출되는 사례도 발생하므로 부적합이 자주 발생하는 농산물, 부적합 검출빈도가 높은 농약 성분들의 철저한 관리가 요구된다. 특히, 농약 사용량 및 사용법 준수, 출하시기 조절 등 농민들의 교육 및 인식 개선이 필요할 것으로 보인다. 안전이 확보된 농산물의 생산과 유통, 소비자의 안전한 식생활을 보장하기 위해서는 농산물에 대한 잔류농약 모니터링을 지속적으로 실시하여 부적합 발생 농산물의 유통을 사전에 차단하는 것이 무엇보다 중요할 것으로 판단된다.
