Background: The presence of heavy metals in the environment, especially in the water creates many health problems. Effective technology for the removal of some of the other methods that are attractive from an economic standpoint, the availability and high power in remove the rest of their advantages. The aim of this study was to investigate the uptake of heavy metals ( Cu , Cd and Pb ) by ...

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...

Among the environmental pollutants, heavy metals according to their irresolvable and physiological effects on living organisms at low concentrations, are of special importance These elements due to low mobility are gradually accumulated in soil Being accumulated in soil, they eventually enter the food chains and threaten human health and other creatures Therefore, studying concentration distrib...

Long-term used of sewage sludge and fertilizer causes accumulation of heavy metals in the soil, which may lead to excessive absorption of these elements by plants and consequently entering these toxic metals into the human and animal food chain. Therefore, this study was conducted to investigate the effects of bio-organic and chemical fertilizers application on the absorption of macronutrients ...

Background and Objective:  Polltion of food chain components such as vegetables to heavy metals is one of the important environmental problems. Remediation management of these metals especially Cd is very important. Thus, this research was done to investigate the effect of Arak municipal waste compost enriched with tire rubber ash on decreasing spinach Cd concentration in a Cd polluted soil. M...

abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.

Introduction: Drinking water should be free of any chemical contaminants. One of the important aspects of drinking water pollution is presence of heavy metals that can be hazardous for consumer’s health. This study was carried out to determine the concentration of heavy metals in urban and rural drinking water networks of Hamadan province in 2016. Materials and Methods: This study was a ...
