Abstract:

Aim of this study was to have known an effect of inhaled particulate matter coal dust and smoking on hematobiochemical profile of worker in coal analysis laboratory. Twenty nine workers were randomly divided into three groups, one control group (n=5), one group who exposed to coal dust but not smoking (CDNS) (n=15), and one group exposed to coal dust and smoking (CDS) (n=9). Control group are subject who work in administrative division which no one exposed to coal dust. Exposed group are subject who work in coal dust material analysis who divided into smoker and non-smoker. The duration of work is less than 10 years. Mean of eosinofil and monocytes counts were decreased significantly in both of coal dust exposure compared to control group (p)
