Objectives: Oxidative stress and DNA damage have been proposed as mechanisms linking pesticide exposure to health effects such as cancer and neurological diseases. We investigated whether protective measures could significantly reduce the levels of biomarkers for oxidative stress and DNA damage in agricultural workers. Methods: In the present study, the levels of malondialdehyde (MDA) and 8-hydroxy-2'-deoxyguanosine (8-OHdG), biomarkers related to oxidative stress and DNA damage, respectively, were analyzed in urine samples collected from agricultural workers in two provinces of Korea (n=60). The influence of wearing personal protective equipment (PPE) and performing protective behaviors on the levels of these two biomarkers was also evaluated. Results: The median urinary levels of MDA and 8-OHdG were 10.45 nmol/mg creatinine and 14.42 ng/mg creatinine in subjects living in region A, while they were 6.25 nmol/mg creatinine and 24.77 ng/mg creatinine in subjects living in region B, respectively. The levels of MDA and 8-OHdG were higher in male farmers. Farmers wearing greater numbers of PPE and performing more protective behaviors had significantly lower levels of MDA. Greater numbers of protective behaviors was significantly associated with lower levels of 8-OHdG. Conclusion: The results of the present study indicate that pesticide exposure could induce oxidative stress and DNA damage in agricultural workers, and that protective measures are important for mitigating pesticide exposure.

As domestic meat consumption increases, the broiler production industry has been larger and denser. The concentration of particulate matter (PM) and harmful gases generated is also increasing inside livestock house. However, the current research status of PM exposed to farm workers and the health effects are in the early stage. To understand PM concentration affecting workers in the broiler house, field monitoring was conducted according to its size distributions. Concentrations of PM₁₀, PM_2.5, and TD (Total Dust) were monitored using personal air samplers with teflon filter during working and moving periods considering the ventilation systems of 6 broiler houses. The purpose of this study is to monitor the PM concentration in the experimental broiler houses operated by forced ventilation system generally used in Korea and to evaluate the regional concentrations through airflow pattern. The PM concentrations were increased from inlet to outlet vents resulting in 1,872 of TD, 1,385 of PM₁₀, and 209 ㎍/㎥ of PM_2.5, respectively. The TD and PM₁₀ concentrations were increased when the workers and broilers were moving. Among them, the particle size that occupied the largest amount of PM was 13.75 ㎛. These results suggest that personal protection equipments are important to reduce the health effect from PM inhalation.

It is a normal circumstance to have high temperature and high humidity in Greenhouses even though these climates are changed by the area, season, climates, the size of the greenhouse, and the crops being raised. Workers in the greenhouses have complained about their uncomfortable work environment and discomfort from the hot conditions, including sunburn. The farmers' ailments are not significantly different between those working in the in greenhouses and those working in the fields. The Farmers' syndrome was almost two times higher for women than those of men for greenhouse workers. This study was developed for functional fatigue clothes for plastic greenhouses which are known for high temperatures and humidity. The ergonomic function and thermal comforts of fatigue clothes were evaluated in the climatic chamber($30.0^{\circ}C$, 70.0%R.H.). The current fatigue clothes which are made of cotton or nylon were purchased at the market. The developed clothes are made of highly absorbent and high speed drying polyester. And these fabrics have excellent elasticity. In this study, the functional fatigue clothes were designed with longsleeved sport shirts and Full length pants. Tre, Tsk, Hcl, HR and the personal subjective sensations such as heat, humidity, and comfortableness were significantly lower when subjects wore the developed clothes made with polyester than the previous attire.
