在餐厅的不同位置（在厨房抽油烟机和大量吸烟的区域），研究了暴露于商业废气废水中的各种金属的行为。暴露时间从4周到60周不等。调查采用化学程序和常规技术进行，包括x射线和金相研究。结果表明，所研究的废水会对某些材料造成污染和腐蚀。在大多数情况下，沉积物在用有机溶剂清洗时被清除。引文:研讨会，ASHRAE交易，1983年，第89卷，pt。华盛顿特区2B。

The behavior of various metals exposed to commercial exhaust effluents was studied in different locations in restaurants (at kitchen hoods and in areas of heavy cigarette smoking). The durations of exposure ranged from 4 to 60 weeks. The investigations were performed using chemical procedures and conventional techniques, including x-ray and metallographic studies. The results show that the effluents studied cause fouling and corrosion of some materials. In most cases, the deposits were removed during washing by organic solvents.
