The use of lowlands for refuse collection point (dumpsite) is a very common practice in Nigeria. However, people cultivated the areas within vicinity dumpsites, without knowledge risk these heavy metals. Therefore, this study was done to evaluate metals pollution soils an active dumpsite. Four (4) soil samples (from 4 locations) at depth 0–20 cm were collected from (e.g. iron lead, nickel and c...

Water and sediment samples were collected from 20 location of the Buriganga river of Bangladesh during Summer and Winter 2009 to determine the spatial distribution, seasonal and temporal variation of different heavy metal contents. Sequential extraction procedure was employed in sediment samples for the geochemical partitioning of the metals. Total trace metal content in water and sediment samp...

Human activities like mining, transport, agriculture, industrial waste disposal and military actions release inorganic pollutants in high concentrations that are toxic to natural ecosystems. Heavy metal pollution causes potential ecological risk. Heavy metals like Cadmium (Cd), Lead (Pb) and Chromium (Cr) when present in high concentrations in soil exert potential toxic effects on overall growt...

Marine ecosystems worldwide are threatened by aquatic pollution; however, there is a paucity in data from the Caribbean region. As such, five heavy metals (arsenic, cadmium, copper, zinc, mercury) were measured in tissues of the scleractinian corals Porites furcata and Agaricia tenuifolia and in adjacent sediments in the Bocas del Toro Archipelago, Panama. Samples were collected from five reef ...

BACKGROUND Environmental justice research suggests that inequalities in the distribution of environmental exposure to chemical pollution systematically disadvantage the lower social strata of society. The effects of these inequalities on the human exposure to pollution are however to a large extend unknown. The purpose of this study is to assess social gradients in human biomonitoring results o...

Nowadays, the entrance of pollutants including heavy metals in environment threatens the life of aquatic animals. In this study, the effect of zinc chloride (6 mg/l) and cadmium chloride (5 mg/l) exposure were studied on the activity of some metabolic enzymes in the liver, gills, brain and muscle in Snow trout (Schizothorax zarudnyi). The results showed that zinc caused a significant increase i...

Background and Aims: The environmental pollution induces rapid development of new technologies cases problems such as pollution of soil, water and air. Heavy metals contaminated can disturb Biodiversity soil. Phytoremediation is one of them new techniques in cleared of heavy metals in soil. A Phytoremediation method enables leaving a contaminated soil from the elements with accumulation of heav...
