Heavy metals bioaccumulation in fish of southern Iran and risk assessment of fish consumption
Background: This study purposed to assess the health risks of heavy metals including nickel (Ni), chromium (Cr), mercury (Hg), and lead (Pb) in three widely-consumed fish from the coast of Bandar Abbas (Persian Gulf) and to determine the maximum amounts allowed for consumption according to the degree of contamination. Methods: This cross-sectional study was conducted in the summer and fall of ...

15 صفحه اولToxicity and Bioaccumulation of Heavy Metals in Spinach (Spinacia oleracea) Grown in a Controlled Environment
The impact of heavy metal toxicity on the shoot and root lengths, total protein, fiber characteristics, moisture content and nutrient composition of spinach (Spinacia oleracea) was evaluated. Plants were grown in pots containing soil and treated with different concentrations (mg/kg) of lead (Pb; 300, 400 and 500), cadmium (Cd; 0.5, 1 and 1.5) and zinc (Zn; 250, 500, and 700) as well as mixtures...
متن کاملAcute Toxicity and Bioaccumulation of Heavy Metals in Red Tilapia Fish
Juvenile hybrid tilapia (Oreochromis sp.) was tested with different concentration of heavy metals under varying exposure time to examine acute toxicity effect on their survival rate and bioaccumulation in fish tissues. Copper (Cu), cadmium (Cd) and zinc (Zn) was used at rates 0.0, 0.50, 1.0, 3.0 and 5.0 mg L-1. The medial lethal concentration of Cu, Cd and Zn (96h LC50) was determined to be 0.4...
متن کاملHeavy Metals Toxicity
A heavy metal is a member of a loosely defined subset of elements that exhibit metallic properties. It mainly includes the transition metals, some metalloids, lanthanides, and actinides. Many different definitions have been proposed based on density, atomic number or atomic weight, and some on chemical properties. Heavy metal toxicity can result in damaged central nervous function, lower energy...
