Prediction study on the exposure of coal mine fuel vehicle exhaust and lung function damage
Objective The aim of this study was to observe the relationship between exposure to coal mine fuel vehicle exhaust and the respiratory system of the organism,with a particular focus on lung function damage,and to explore the risk factors for the occurrence of lung function decline in coal miners.Methods The current situation study was used to select the study subjects from the coal miners who un-derwent physical examination in northern Shaanxi in 2021 by cluster sampling.The subjects were divided into two groups based on their lung function:a normal group and an abnormal group.The relationship be-tween lung function abnormalities and exposure to coal mine fuel vehicle exhaust was then examined using multifactorial logistic regression.Results A total of 564 study subjects were included,and the differ-ences in age,gender,and length of service between the normal and abnormal lung function groups of coal miners in northern Shaanxi were statistically significant(all P＜0.05).The differences in carbon dioxide(CO2),nitric oxide(NO),nitrogen dioxide(NO2)and polycyclic aromatic hydrocarbon(PAH)expo-sure between the two groups were statistically significant(all P＜0.05).After adjusting for potential con-founding factors such as age and seniority,miners exposed to high levels of NO(OR=2.01,95％CI:1.43-3.04,P＜0.001)and PAH(OR=1.81,95％CI:1.01-4.18,P＜0.05)exhibited a heightened risk of developing lung injury.Injury risk was observed among coal miners with high CO2 exposure(OR=1.24,95％CI:0.71-2.36)and NO2 exposure(OR=1.43,95％CI:0.54-4.17),but no significant difference was noted between these groups(all P＞0.05).Conclusions Among coal miners,males,older,and seniority,exposure to NO and PAH from fuel vehicle exhaust are risk factors for lung function impairment.It is suggested that targeted protective measures should be taken to reduce lung function injury in coal miners.
