摘要：

Occupational exposure safety remains a major issue during greenhouse spray applications in China. Herein, we tested the safety of 2 protective clothing types to be used in cucumber greenhouses: 100% cotton hooded coveralls and non-woven fabric hooded coveralls. A hand-operated knapsack sprayer was used for chlorothalonil application (75% WP). The whole-body dosimetry technique was used to collect dermal exposure samples, including gloves and socks. In the absence of any personal protective equipment (PPE), chlorothalonil application resulted in a total dermal exposure of 5759.5g/h. When 100% cotton hooded coveralls (including single-layer gloves) and non-woven fabric hooded coveralls (including rubber gloves) were used as protective measures, the total dermal exposures of the applicators were 5759.5 and 2511.3g/h, representing deflection rates of 88.7 and 95.1% of the total dermal exposure in the absence of PPE, respectively. Next, dermal exposure when using 2 cotton garment layers (100% cotton hooded coverall as the outer-layer garment and 85% cotton underwear as the inner-layer garment) was analyzed. The penetration rate of the outer-layer garment was first estimated; the penetration rate for the left lower leg section was 1.8% (the lowest), and that of the chest section was 12.1% (the highest), with a mean penetration rate of 6.3%. When a single-layer 100% cotton coverall (including 100% cotton gloves) and a non-woven fabric coverall (including rubber gloves) were used as protective measures, the main exposure site among the applicators was the face (including the neck). Thus, to reduce the exposure risk of farmers during chlorothalonil application, it is essential to strengthen protective clothing and improve protection for the face (including the neck), which is often exposed. Moreover, it is essential to improve knowledge on occupational safety and self-protection measures among farmers. These findings may provide useful information for risk mitigation and management and epidemiological studies in China.
