Anthropogenic environmental changes are hypothesized as main reasons for animal species population declines. Heavy metals contamination is one of the worst threats to animals among human-caused threats. As most of the heavy metals bioaccumulate in organisms, analyzing concentrations of heavy metals in long living animals, such as turtles, would be very useful for biomonitoring of environmental ...

Background and purpose: Exposure to heavy metals can cause neurological, respiratory and cardiovascular disorders, imbalance of hormones, hair loss, infertility, and abortion. Kohl containing heavy metals can lead to such complications due to long-term contact with the lining of the eye. The aim of this study was to investigate the contamination level of Kohl by heavy metals (cadmium, zinc, nic...

Introduction: Uncontrolled and improper landfilling of solid waste increases the concentration of heavy metals in the soil. Therefore, this study aimed to investigate soil contamination with heavy metals in the landfill of municipal and hospital waste in Sabzevar city by compiling a map of the severity of heavy metal pollution in the soil. Materials and Methods: Concentrations of heavy metals ...

Lead, cadmium, mercury and arsenic are the most important heavy metals which may cause health risks following consumption of contaminated foods. Table salt is one the mostly used food additive with unique place in food consumption. Although purified table salt is expected to have lower level of contamination, some Iranians still prefer to use rock salt. Use of rock salt for food purposes has be...
