Heavy metals exposure in animals can lead to profound effects in growth and development. Heavy metals can target all protein metabolisms in the body, and are capable of disturbing most of the functions in animals where proteins are involved. Heavy metals primarily cause biochemical lesion and effects in altering protein metabolism. Chronic heavy metal exposure resulted in decrease in hepato-pancreatic weight, hepato-somatic index and embryonic length with subsequent reduction and length and...

Plants have mechanisms for accumulation, tolerance or alleviation of high levels of heavy metals in contaminated soil. Some contaminants can be absorbed by the plants and are then broken down by plant enzymes. The objective of this particular study was measure the potential activities of three enzymes (dehydrogenase, protease and phosphatase) in the alfalfa rhizospheres under the stress at different concentrations of cadmium salts, and inoculated different biofertilizers strains of S. meliloti...

Soil contamination by heavy metals is a worldwide environmental problem. Hence determining the chemical forms of a metal in soils is important to evaluate its mobility and bioavailability. This study determined the distribution and speciation of some heavy metals (Fe, Cu, Zn, Pb and Cd) in soils around some selected auto repair workshops in Oghara, Delta State, Nigeria. Soil samples were collected with the aid of soil Augar within a depth of 0 – 15 cm from the vicinity of the four selected...

Vegetables play key role in maintaining the nutritional status of humans. The dominant elements in vegetables are calcium, potassium, iron and sodium etc. which provide alkalizing effects, neutralizing the acidity produced by other foods, especially those of animal origin. Heavy metals in vegetables accumulate through uptake from soil, water and atmosphere. The intake of heavy metals through diet leads to several disorders such as kidney damage, nervous disorder, bone disease and tubular...

The determination of total metal content is usually insufficient to fully assess the environmental impacts of contaminated sediments. In order to differentiate metals of lithogenic from those of anthropogenic origin and assess their bioavailability and potential toxicity, detail information on their partitioning to various geochemical fractions of the sediment is necessary. In recent times there has been a lot of concern on the rate at which River Delimi ecosystem deteriorate as it passes...

Heavy metals such as Zinc, Nickel, copper, Manganese, cadmium, chromium Iron and lead, are major (heavy metal) pollutants in the environment, particularly in areas with anthropogenic activities and industrial activities. Heavy metal accumulation in soils is of great concern in agricultural production due to the adverse effects on food safety and crop growth. The amount of consumption of fresh water is equal to the amount of discharge of wastewater as effluent. In this aspect the present study...

Heavy metals were determined in columnar sediment samples of the Yalu River estuary watercourse. The environmental status was assessed by using the pollution load index, geologic cumulative index, potential ecological harm index and Nemerow index. It is shown that the geologic cumulative index and Nemerow index show a low level of heavy metal pollution indicating that the pollution of K1 columnar samples is not serious. The results of the ecological risk index and the pollution load index are...
