Background: Given the importance of vegetables in the food pyramid, their safety is very important from view point of public health. Vegetable contamination by heavy metals can lead to bioaccumulation of these toxic and disease-causing elements in the body of consumers. Therefore, in this study, the concentration of some heavy metals, including lead (Pb), cadmium (Cd), zinc (Zn) and copper (Cu)...

recreational waters should be considered as risks for enterococcal infections in regions with high utilization and long exposure periods. the aim of this study was to investigate the resistance of enterococci to selected antibiotics and some heavy metals [pb+2, fe+2, zn+2 and cr+2]. a total of 75 enterococcal isolates was obtained from 54 bathing and fishing water samples from 9 bathing and fis...

dust pollution has become a serious environmental problem especially in recent decades. the present study aim was the investigation of the levels of pm10 concentration in kermanshah, western iran and also measured five important heavy metals (pb, cd, as, hg and cr) in some samples during 2005 to 2011.a total 2277 samples were collected from air pollution measurement station belonging to the dep...

Many of mushrooms species from the forest area of Bucegi Mountains are consumed by the native population without thinking about the heavy metals uptake in the human body. From all the edible species we choose eight mushrooms, part of them considered edible and part with uncertain edibility. Heavy metals concentration in the fruiting body of mushrooms are different from one species to another an...

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...

abstract mine excavation, concentration and transportation of minerals make southern esfahan municipality and suburb of sepahanshahr vulnerable to pollution and endanger their people by heavy metals. nowadays, spectrophotometers and spectral reflectance of soils in different parts of spectrum are applied for estimating soil characteristics and pollutants. this research was conducted to study th...

Background & objectives: Since many plants have high efficiency in absorbing heavy elements, the use of phytoremediation is of great importance. The purpose of this study is to identify native plants that absorb heavy metals. Also, the possibility of using them in phytoremediation technology in soils contaminated with heavy metals (around the petrochemical industry of Razi fertilizer in Tehran ...
