چکیده
Determination of environmental pollution in the surface water is very important. So, in this study, determination, and health risk assessment were evaluated. The pollutions such as anions, cations, and heavy metals were analyzed in surface water by photometer spectrometry and atomic absorption spectrometry (AAS). TDS for wet and dry seasons go from ۱۲۲.۱۷±۱.۷۴ mg L-۱ to ۶۳.۸۰±۰.۸۶ mg L-۱. The high phosphate levels in both wet and dry seasons are recorded from ۶۰.۷۴±۰.۶۱ - ۶۰.۲۷±۰.۳۸ mg L-۱ in both seasons. Iron values observed range from ۸.۴۲±۰.۰۶ to ۶.۲۸±۰.۱۱ mg L-۱ in the wet and dry season, Cu was recorded between ۰.۰۸±۰.۰۱ - ۰.۰۷±۰.۰۱ mg L-۱, Mn recorded from ۰.۰۷±۰.۰۱ to ۰.۰۶±۰.۰۱ mg L-۱, Zn recorded between ۲.۲۹±۰.۰۹ - ۱.۱۵±۰.۰۹ mg L-۱, and Pb recorded from ۰.۶۹±۰.۰۹ to ۰.۴۰±۰.۱۸ mg L-۱ while Cd and Ni were not detected in the study. Water quality index (WQI) values were determined as ۵۴۹ for wet and ۳۲۸ for the dry season, the hazard indices for both seasons are below one. The outcomes in this present study showed that the level of Pb in the surface water could present a carcinogenic risk to both adults and children. All heavy metals results were validated by ET-AAS.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
