The Effect Of Exposure to Pesticides on Immnunolgical Indicators of Qat Farmers (Lahj Governorate – Yemen)

Abstract

The aims of this study was to evaluate the health status of pesticides spray workers of Qat farmers in some areas of Lahj governorate-Yemen through testing the immune indicators related to the body cellular defense system in IgG, IgA, IgM and number WBC, lymphocytes and nitrophilic. The study was conducted on 30 male volunteers of pesticides spray workers, (randomly chosen), in addition to 20 male volunteers who didn’t work in pesticides spray (as a control group). The range age of the volunteers was 15-57 years. , and the period of work of the 30 volunteers ranged in spraying pesticides from 3 to 32 year. The volunteers were divided according to age into four experimental group and the normal persons who did not expose to pesticides spray were also divided according to age into four control groups.                                                                            The results showed that the mean age of all the groups working in the spraying was lower than the mean age of  all the four control groups and it was not statistically significant . it was found  that the average level of  lgG ,  lgA  and  lgM groups  antibodies in all working  in the spray was higher than its average level in the all the four control groups and this increase is statistically significant.  The results also showed that the average number  of WBC  ,lymphocytes and neutrophils  in all groups working  in the four sprays  was higher  than the average  of their  numbers in all four  control groups with statistical  significance . we conclude from our study that pesticides affect immune system dysfunction through significant elevation of some immunological indicators such as lgA and WBC.
