长期接触低浓度一氧化碳(CO)对人体的危害如何是一个有争议的问题。为此对我公司选矿厂竖炉车间长期接触低浓度CO的工人进行健康调查,其结果报告如下: 车间一般情况 该车间有竖式焙烧炉16座,炉内燃烧高炉煤气,由于设备缺陷,经常有CO逸出。在车间内选测了空气中CO浓度(对磺酰胺苯甲酸比色法)11处48次。每次测定均取两个平行样
Long-term exposure to low levels of carbon monoxide (CO) on the human body how to be a controversial issue. To this end, the company’s mineral processing plant shaft furnace long-term exposure to low concentrations of CO workers to conduct a health survey, the results are reported as follows: Workshop General There are 16 vertical roasting furnace, furnace blast furnace gas, due to equipment defects, often There CO escape. In the workshop, the concentration of CO in the air (for sulfonamidobenzoate colorimetric method) was selected at 11 locations 48 times. Take two parallel samples for each determination
