To this, after 96 h-LC50 determination, the fish were exposed to 10% of LC50 concentration (4.3 mg / l) and after 21 days of exposure, the blood, gill and kidney were taken. The results showed that flonicamid intoxication decreased chlorine and increased potassium concentrations in fish blood, but had no effect on sodium and calcium levels. In addition, the flonicamid exposure was caused numerous damages to the gills and kidney. In the gill, the secondary lamellar edema, secondary lamellar fusion and primary lamellar hyperplasia were observed in the gill. Also, the exudate and melanomacrophage accumulation and degeneration of renal tubules were observed in kidney of the pesticide-exposed fish. The results showed that flonicamid has serious effects on the gill and kidney tissues of carp. These injuries are responsible for some of the ionic changes in fish blood. Therefore, it is recommended that this pesticide is used in farms, care should be taken to prevent the pesticide from entering the water resources in order not to threaten fish health.}, keywords = {Health,pesticide,histopathology,Blood}, title_fa = {بررسی اثر مسمومیت مزمن با سم فلونیکامید بر غلظت یون های خون و آسیب های آبشش و کلیه در ماهی کپور معمولی (Cyprinus carpio)}, abstract_fa = {با توجه به فعالیت کشاورزی در نزدیکی مزارع پرورش ماهی و منابع آبی، احتمال مسمومیت با سموم کشاورزی در ماهی­ ها زیاد است و به همین دلیل، این تحقیق به هدف بررسی اثر مسمومیت با فلونیکامید بر غلظت یون­ های خون و آسیب­ های بافتی آبشش و کلیه ماهی کپور بود. به این منظور، پس از تعیین LC50 96 ساعته، ماهی­ های در معرض 10 درصد غلظت LC50 (4/3 میلی­ گرم در لیتر) قرار گرفتند و پس از 21 روز مواجهه با سم، نمونه خون و بافت آبشش و کلیه از ماهی­ها گرفته شد. نتایج نشان داد که مسمومیت با فلونیکامید باعث کاهش معنی­ دار (0/05
