在冶金、电镀、制革、水泥等行业以及煤和石油燃烧的废气中,含有颗粒状铬烟雾,将其吸入呼吸道有刺激和腐蚀作用,引起咽炎、支气管炎,长期接触甚至发生慢性铬中毒。我国职业卫生标准GBZ2.1—2007规定工作场所铬及铬化合物职业接触限值(以铬计):时间加权平均容许浓度PC-TWA为0.05 mg/m3,短时间接触容许浓度PC-STEL为0.15 mg/m3。职业卫生检测目的是能反映劳动者在工作场所接触空气 In the metallurgy, electroplating, leather, cement and other industries as well as coal and petroleum combustion emissions, containing particulate chrome smoke inhalation of the respiratory tract irritation and corrosion, causing pharyngitis, bronchitis, chronic exposure and even chronic chromium poisoning. Occupational Health Standard GBZ2.1-2007 in our country stipulates the occupational exposure limits of chrome and chromium compounds in the workplace (calculated as chromium): the time-weighted average allowable concentration PC-TWA is 0.05 mg / m3 and the short-term exposure allowable concentration PC-STEL is 0.15 mg / m3. The purpose of occupational health testing is to reflect that workers are exposed to the air in the workplace
