Surveillance for the Effects of Carbon Monoxide on Health in a Tianjin Gas Factory

Abstract

This report describes the surveillance over the past 8 years of carbon monoxide (CO) levels in a factory producing gas from coal. Where workers were working in areas of the factory where the air might be polluted by CO we found that measurement of carboxyhaemoglobin (HbCO) levels in their blood was a sufficiently sensitive test of exposure. Measurements on samples taken before and after a shift showed a significant difference. Our measurements of a HbCO blank control in two normal population groups was very close to the biological limit value of that for normal groups in the USA and Germany.

“…[2][3][4][5][6][7] These harmful chemicals can damage multiple organ systems such as the respiratory tract, cardiovascular system and nervous system, and cause cancer and skin damage. [8][9][10][11][12][13][14][15][16] Workers working in semiconductor factories may be exposed to chemical hazards that can cause occupational diseases.…”
