Yes,because the dust in rice mill is small can towards respiratory. Today’s focus on the study on respiratory morbidity in the rice mill employees between the group sample and the control group. If you don’t mind,we’ll leave questions till the end.
From Table 1 talk about “Distribution of respiratory symptoms in 120 rice mill worker by duration of employment” found respiratory symtoms find more duration of employment. For example : Eye burning in less 10 years from 47 peaple have the symptoms 21,more than 20 years have the symptoms 38 peaple . and If you look at Table 2 you can see duration of exposure to rice dust even more exposure group have respiratory illness more ,when comparision between exposure group and control group you can see exposure group have respiratory illness more than control group. From 2 table show that duration of employment and respiratory symptoms there is a significant correlation.
