The Fenvalerate(Fen) concentration in synthetic and assembling shop air of Fenpesticide plants were 0.023, O.122mg/m~3 res-pectively. The workers operated manuallyand without preventive measures. The majorsymptom of the exposed was skin itching,and was aggravated on every monday. Thevisual-response time of the exposed workerswas prolonged, which may relate to prolong-ation of the motor conduction latency rate(MCLR) of rat sciatic nerve. The animal ex-periment showed that Fen could reduce theability, in the Y-maze test, of learning andmemory and the faculty, in the former limbhanging test, of nerves and muscles coordin-ation and of muscle stamina. The results ofmicronucleus test showed that Fen make themicronucleus rate in blood cells of workersand mice rise. It revealed that Fen perhapswas harmful to the human genetic effect. It issuggested that local ventilation installationswere set up in shops, especially in pouringFen into ampoule and sealing ampoule shopsections. The skin of the exposed workersated with Yi-Ling cream.

江苏激素研究所Fen农药厂合成和分装车间空气中Fen浓度分别为0.023和0.122mg/m~3,分装工人手工操作,室内和工人均缺乏防护设备。接触者的主要症状是皮肤瘙痒,并有“星期一加重现象”,同时可使工人的视觉-运动反应时延长,这也许与动物实验中Fen使大鼠坐骨神经运动传导潜速率的延长有关。动物实验还提示Fen使大鼠“y迷宫”达标所需训练次数增加,前肢悬挂耐力时间缩短(呈现一定的剂量-效应关系)。即Fen可影响大鼠的记忆、学习能力和神经肌肉协调性及肌耐力。Fen还使小鼠及工人血细胞中的微核发生率明显升高,说明Fen对人类遗传效应存在一定威胁。建议车间中特别是灌药和封口工段加用局部密闭通风罩等防护措施,接触者皮肤抹用益灵霜。

Three object functions of local ventilation in mine are optimized,these are localventilating class whole-pressure efficiency, local-ventilatingnoisy acoustical power and combined object functions of theabove combination. A combination of the whole-pressure efficiency and the noisyacoustic power of local ventilating classare proposed to optimize the combined object functions by comparatively analyzing itsresults. Hence, the main paremeters are obtained for desinging hi-efficiency and low-noisy...
