4%双唑草腈悬浮剂施用人员健康风险评估

Health risk assessment of pyraclonil 4%SC on operators

对4%双唑草腈悬浮剂进行了施用人员初级健康风险评估。分别在直播田和移栽田2种不同工作场景下,评价了4%双唑草腈悬浮剂对施用人员在配药和施药过程中的综合风险系数。试验结果表明:在较差防护及中等防护下,2种工作场景的综合风险系数RQ为2.9467~6.6659,风险超出可接受范围;而在较好防护下,2种不同工作场景的综合风险系数RQ均小于1,风险可控。

The primary health risk assessment of pyraclonil 4%SC on operators was carried out.At two different work scenarios of transplanted rice and direct-seeding rice,the comprehensive risk coefficients of pyraclonil 4%SC to the operators were evaluated in this report.The results showed that at the two work scenarios,the comprehensive risk quotients of pyraclonil 4%SC to operators were 2.9467-6.6659 under poor protection and medium protection conditions,which indicated that the health risk was out of the acceptable range.However,under better protection condition,the comprehensive risk quotients at two different work scenarios were less than 1,and the health risk was acceptable.
