دراسة تأثير تراكيز من الزئبق على المحتوى البروتيني والكلوروفيل الكلي والكاروتين في بعض النباتات المائية

Abstract

The current study was conducted to investigate the effect of different concentration of mercury on physiological state for same aquatic plant by study accumulation of mercury within tissues and determine concentration of total chlorophyll , carotene and protein through exposure of four aquatic plants (Potomogeton perfoliatus, Phragmitus australis Myriophyllum verticillatum , Ceratophyllum demersum ) for three concentration of mercury (1,2,3) mg/l as mercury chloride mixed with wastewater discharge from The Al- Furat Company For Chemical Industries in Sadat Al – Hindiyah-Iraq for 13days ,The results of study demonstrated height various in concentration of mercury in tissue of the plant in the end of experiment and assume arranged as following P. australis > P. pectinatus > C. demersum > M. verticillatum and the aquatic plant response the through determine of concentration of total chlorophyll , carotene and protein were studied the result show decrease concentration of total chlorophyll , carotene and protein for the aquatic plant .
