Introduction: Unsustainable natural resources utilization is on the increase in the developing countries thus the ability of many local communities to meet their basic needs including food, water and shelter is jeopardized. Uncontrolled gold-mining in Sikasso region is one such an anthropogenic activity that is of great environmental concern to the local and national governments of Mali owing t...

Heavy metals widely enter into aquatic ecosystems, and cause various environmental problems due to bioaccumulation and biomagnification in food chains. The accumulation of heavy metals in bivalve tissues is affected by a number of intrinsic and extrinsic factors such as physiological conditions, growth, seasonal changes, pH, salinity, temperature, genera and age. The present study investigated ...

Contamination of the aquatic environment and living things with pollutants is increasing daily. Among these pollutants, heavy metals come to forefront regarding toxicological public health due their widespread use, toxicity, resistance degradation, as well accumulation biomagnification in food chain. The study aimed determine essential (Cr, Cu, Fe, Mn, Ni, Zn) non-essential (As, Al, Cd, Pb) met...

Heavy metal ions are highly toxic for living organisms especially after bioaccumulation and biomagnification, which possess a serious threat to human health ecological environment. The rapid, portable, efficient analytical methods urgently needed the determination of heavy metals in different media. Due unique advantages field-effect transistor (FET) sensors including fast response, easy manipu...

During the Spanish colonial era, ships frequently transported mercury across Atlantic to New World be used in gold mining. As many of those eventually sank, shipwrecks may represent a local source contamination marine environment. In this context, evaluating coastal sediments and magnification food webs is crucial for understanding dynamics estimating exposure life locations where occurred. Thi...

The removal of heavy metals present in water is an issue environmental interest, due to bioaccumulation,
 biomagnification and the carcinogenic mutagenic effects on living beings. objective study was use plantain peel residues Chromium (VI) Nickel (II) continuous system, evaluating effect bedheight, temperature adsorbent particle size process; obtaining a 98.7% 99.71% yield for Cr Ni(II), ...

Hospital wastewater contains heavy metals that threaten environmental and human health through bioaccumulation biomagnification. Each metal contributes a different impact on the environment. Monitoring in is essential to prevent those severe impacts. However, it still rare for study assess obtained from discharge of hospital Indonesia. Therefore, this investigated 14 parameters wastewater. We t...
