Background and Objective: Population explosion and human ever-increasing demands has been resulted in industrialization which its mismanagement led to land pollution and consequently irreversible harm to nature and living organisms. Thus, it is an important measure to investigate the role of industrial centers in soil pollution. Materials and Methods: We studied Mobarakeh Steel Industrial Comp...
Background and Aim: Agricultural and industrial activities, as well as population growth, have resulted in increases in the amounts of pollutants in the environment, the human body, and other organisms. Cadmium is one of the common heavy metals entering the biological cycles through different paths causing disease in humans, animals and plants. This study aimed at determining cadmium levels and...
Heavy metals including cadmium produced as a result of urban, industrial and agricultural activities lead to the water pollution. Also, considering the growing need for silviculture in Iran, it is necessary to conduct a comprehensive research on fast growing and evergreen species of Eucalyptus and their role in heavy metals' absorption. To achieve this goal, Eucalyptus occidentalis seedlings we...
Background and Aim: Lead and cadmium are as main environment pollutants, and even in low concentrations have harmful effects on human health. Baby teeth are efficient indicators of environmental exposure of children to heavy metals. The aim of the present study is to determine the concentration of lead and cadmium in deciduous teeth of 5-12 year old girls and boys in Birjand in 2010. Materials ...
This study evaluates the potential of Arthrobacter nicotiniae to preferentially remove lead, cadmium, silver and zinc from contaminated soil Amaonye-ishiagu Agricultural Forest, Ebonyi State, Nigeria using standard methods. The revealed optimum values factor as 8ml nutrient volume, 5g organism, 30oC temperature, pH 8 stirring frequency 4pw. showed 79.78% removal 61.50% 48.59% arsenic 7.04% on 3...
A large amount of agricultural land is located in close proximity to the metropolitan areas, it means near industrial enterprises and highways which giving rise inevitable soil pollution by heavy metals, most toxic them are cadmium, mercury lead. The plant products harvested from such areas frequently contains metals make unsuitable for human or animal consumption. Studies have shown that pre-s...
phytoremediation is a biological method by which plants are used to remove environmental pollution caused by toxic elements such as the accumulation of cadmium, copper, lead, chromium, etc. from soil. the arbuscular mycorrhizal fungi (amf) help the plant to increase uptake and translocation of low mobility nutrients and also micronutrients. in this research, arbuscular mycorrhizal inoculant was...
Exponential industrialization and rapid urbanization have resulted in contamination of soil by metals from anthropogenic sources in Dongguan, China. The aims of this research were to determine the concentration and distribution of various metals (arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn)) in soils and identify their potential heal...
Purpose. Knowing and evaluating the degree of pollution caused by elements under study, Statement potential environmental hazards index. in Samarra city-Iraq to know limits mineral pollution, because an increase them is harmful humans. Methodology. The first step starting work for current as modeling was carried out a field tour November each region depth, concentrations heavy approved study (m...
Anthropogenic pollution poses a threat for the environment and wildlife. Trace metals (TMs) are known to have negative effects on haematological status, oxidative balance, and reproductive success in birds. These pollutants particularly increase in concentration in industrialized, urbanized and intensive agricultural areas. Pollutants can also interfere with the normal functioning of the immune...
