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...

Tailings dams in mining areas frequently experience the phenomenon of haphazard dumping and stacking a large amount tailings waste. Under influence surface runoff groundwater infiltration, heavy metals from waste can migrate to surrounding underground soil, resulting extensive metal pollution. To analyze pollution level ecological risk an abandoned lead–zinc mine dam, this study first employed ...

The purpose of the study is to assess reliability sampling results concentration tailings at experimental site Tereklikan Kanjol deposit (Tajikistan). involves description dredging waste and dumps under investigation. total length sampled interval 12 m. It was divided into two local intervals 4 6 m long according geological features (amount veined quartz material). Each type component process i...

pomegranate is an ancient edible fruit with various pharmaceutical bioactivities such as antioxidant, lipid regulation and anti-inflammation. in this study the effectiveness of pomegranate pith and carpellary membrane (ppcm) extract in treatment of experimental lead intoxication was assessed in rats. female wistar rats were exposed to 1000ppm lead acetate in drinking water for 35 days and treat...

Wilson's Disease (WD) is an autosomal recessive disorder of copper metabolism resulting in a pathological accumulation of this metal, initially in the liver and later in other organs, mainly brain. Treatment with copper chelating agents and zinc salts results in a depletion of copper deposits and prevents or reverses the clinical manifestations. Copper deficiency may cause haematological and ne...

The present study aimed at investigating the effects of copper and zinc in Vigna mungo (L.) growth and metabolism. Physiological parameters decrease consequently with increasing copper and zinc concentration in nutrient medium. Copper at 0.2mM concentration led to 32.12% and 47.82% reduction in fresh weight and dry weight respectively whereas, zinc at 1.50mM concentration resulted in 23.83% and...

in this study, the performance of electro-coagulation in combination with aluminum sacrificial anode, in removal of zinc and copper has been investigated. several parameters, such as pollutant concentration, ph, electrical potential, cod, turbidity and contact time were studied to achieve a higher removal capacity. variable concentrations (5-50-500 ppm) of zinc and copper solutions were prepare...

Cobb 500 broilers were fed diets that were zinc deficient (35ppm), supplemented with 70ppm zinc sulfate, or 70ppm zinc sulfate + 35ppm organic zinc (MINTREXTM Zn or zincmethionine). Half the birds were given a coccidiosis vaccine (ADVENT® coccidiosis control) at day of age, and challenged with all three species on day 24. MINTREX Zn and zinc-methionine both significantly increased intestinal br...

Gossan ore is typically abandoned after mining, which not only increases mining production costs but also wastes mineral resources, and its long-term accumulation can easily lead to environmental pollution hazards. Therefore, this paper takes zinc-containing gossan as the research object and, based on high content of zinc iron minerals in ore, study conducts a roasting experiment prepare ZnFeO4...
