在工农业生产中,生产环境经常会发生高温与化学毒物两种职业危害同时存在的情况。加之我国大部分地区夏季炎热且持续时间较长,高温与化学毒物的联合作用就显得更为突出。充分认识二者联合作用的危害性,加强职业病的预防,对于保护职业人群的身体健康至关重要。任何一种化学物质只有在一定条件下才会出现毒作用,其中温度就是一个重要条件。例如:有机氟聚合物在加热时会发生热裂解,而产生多种无机和有机氟的混合物。铅、汞被加热时逸出的蒸气可成倍增加。高温作业可使苯、二甲
In industrial and agricultural production, the production environment often occurs at high temperature and chemical occupational hazards of both occupational hazards exist. Coupled with the hot summer in most parts of China and the longer duration, the combined effect of high temperature and chemical poisons is even more prominent. A full understanding of the dangers of the combined effect of the two and strengthening the prevention of occupational diseases are of crucial importance in protecting the health of the working population. Any kind of chemical substances only under certain conditions will appear toxic effects, of which temperature is an important condition. For example, organic fluoropolymers pyrolyze upon heating to produce a mixture of various inorganic and organic fluorides. Lead, mercury is heated to escape the vapor can be doubled. High temperature operation can benzene, dimethyl
