Respiratory, hepatic, renal, and hematological disorders among adolescent females environmentally exposed to pesticides, Menoufia governorate, Egypt.

Adolescent females are often environmentally exposed to pesticides by living near agricultural fields, by using pesticides at home, or by having contact with contaminated clothes and pesticide application work tools. This study assessed respiratory, hepatic, renal, and hematological health disorders that might arise due to environmental exposure to pesticides among adolescent females. A cross-sectional study was conducted with 100 adolescent females environmentally exposed to pesticides that had one or more of their family members working as seasonal pesticide applicators and 50 nonexposed (control) adolescent females from Menoufia governorate, Egypt. The studied period of pesticide application season of the cotton crop was from May 1 to September 1, 2017. Participants completed a self-administered questionnaire about pesticide exposure and respiratory, hepatic, renal, and hematological disorders. In addition, serum acetylcholinesterase (AChE), spirometry, complete blood count, and liver and kidney function tests were measured pre and post-pesticide application season. The control adolescent females had a higher AChE activity, a lower prevalence of respiratory symptoms, and higher means of spirometric measurements than the exposed group. During the pre- and postseason, the exposed group presented a prevalence of (6%, 24%) for cough, (4%, 11%) for rhinitis, and (6%, 26%) for dyspnea during the pre and postseason, respectively. In addition, there was a decrease in means of spirometric measurements (FEV%, FEV/FVC%, FEF %, and PEF%) in the postseason compared to preseason among the exposed group. Also, there were significant associations between (AChE) activity and both the prevalence of respiratory manifestations and spirometric measurements among the exposed females. On the other hand, there was a statistically significant increase in red blood corpuscle (RBC) and lymphocyte counts, and a statistically significantly lower mean hemoglobin level among the exposed group (postseason) than each of their pre-season values and the control group (P < 0.05). AChE level, total protein, albumin, and albumin/globulin (A/G) ratio levels were statistically significantly lower, while SGPT, SGOT and globulin, blood urea, and serum creatinine mean levels were statistically significantly higher among the exposed group (postseason) than either of their preseason or the control group (P < 0.05). There was a positive correlation between the AChE level and all studied CBC parameters for the exposed group reaching a statistically significant level with basophils (P < 0.05). Also, there was a negative correlation between the AChE level and each of SGPT, SGOT, ALP, globulin, blood urea, and serum creatinine for the exposed group reaching a statistically significant level with each of SGPT and SGOT (P < 0.05). At the same time, a nonsignificant positive correlation was found between AChE level and each of total protein, albumin, and A/G ratio (P > 0.05). So, environmental exposure to organophosphorus pesticides has a detrimental impact on respiratory, hepatic, renal, and hematological systems of adolescent females living in rural districts at the Menoufia governorate. Educational and training intervention programs on pesticide handling and safety precautions are recommended for protecting both pesticide workers and their family members who might be exposed.
