The presence of toxic heavy metals such as As, Cd, Pb, Cr, Mn, Ni, Cu, and Zn in nationally representative samples of highly consumed fruits and vegetables was determined by inductively coupled plasma mass spectrometry (ICP-MS). Their concentrations exceeded the maximum allowable concentration (MAC)...

Although fish, crustacean, and shellfish are significant sources of protein, they are currently affected by rapid industrialization, resulting in increased concentrations of heavy metals. Accumulation of heavy metals (V, Cr, Mn, Ni, Cu, Zn, As, Se, Mo, Ag, Cd, Sb, Ba, and Pb) and associated human he...

Soil pollution, influenced by both the natural and anthropogenic factors, significantly reduces environmental quality. In this study, six hazardous elements (Cr, Ni, Cu, As, Cd and Pb) in 12 different land-use urban soils from Bangladesh were assessed. The ranges of Cr, Ni, Cu, As, Cd and Pb in stud...

Heavy metals are known to cause deleterious effects on human health through food chain. Human health risks were evaluated from consumption of heavy metal contaminated fish from Buriganga River in Bangladesh. Whole body of five fish species (Puntius ticto, Puntius sophore, Puntius chola, Labeo rohita...

Trace metals contamination in commercial fish and crustaceans have become a great problem in Bangladesh. This study was conducted to determine seven trace metals concentration (Cr, Ni, Cu, Zn, As, Cd, and Pb) in some commercial fishes and crustaceans collected from coastal areas of Bangladesh. Trace...

Trace metal contamination is a major problem globally, especially in developing countries. In this study, the levels of trace metals (Cr, Ni, Cu, As, Cd, and Pb) in water and sediment of some peripheral rivers of Dhaka City, Bangladesh, were investigated. Huge amount of municipal wastes, industrial ...

Seven food items, namely, meat, egg, fish, milk, vegetables, cereals and fruits were collected from Bogra district, Bangladesh to evaluate the levels of heavy metal and associated health risk to the adults and children. The samples were analyzed for the quantification of selected heavy metals (Cr, N...

Concentrations of six trace elements [chromium (Cr), nickel (Ni), copper (Cu), cadmium (Cd), lead (Pb) and arsenic (As)] were assessed in 'non-piscine protein source' foodstuffs (meat, milk and eggs) to evaluate contamination level and human health risks in Bangladesh. The range of Cr, Ni, Cu, Cd, P...

Concentrations of six heavy metals (chromium, nickel, copper, arsenic, cadmium, and lead) in fish and vegetables were estimated to evaluate contamination levels and health risks for Bangladeshi adults. The analyzed metals varied between different species of fish and vegetables. Metals like Ni, Cd, a...

Acute toxicity of arsenic to tilapia (Oreochromis mossambicus) and its histopathological impacts on gill and liver tissue were evaluated. The median lethal concentration (96 h; LC50) of arsenic (NaAsO₂) was calculated as 28.22 ppm in repeated semi static test method. Fish were exposed to 3 ppm, 28 p...

The objective of this study was to assess the contamination level of trace metals in soil and vegetables and health risk to the urban population in Bangladesh. The range of Cr, Ni, Cu, As, Cd, and Pb in agricultural soils was 158-1160, 104-443, 157-519, 41-93, 3.9-13, and 84-574 mg/kg, respectively....

Arsenic (As), particularly of its inorganic form (iAs) is highly toxic, and its presence in food composites is a matter of concern for the public health safety, specifically in Bangladesh which is regarded as the most arsenic affected country throughout the world. This study was carried out to inves...
