The risk imposed upon society by consumption of foods contaminated with metals and metalloids is an environmental problem attributed to the increasing number of mining extraction activities currently underway in Colombia. The aim of the current study was to determine concentrations of mercury (Hg), lead (Pb), cadmium (Cd), and a metalloid arsenic (As) found in the species of most consumed fish ...

background: the aim of this study was to determine bioavailability heavy metal concentrations of cu, cd, cr, co and zn and health risk assessment in different types of klang district, selangor (malaysia) urban surface soil using in physiologically based extraction test in vitro human digestion model. methods: a total of 76 urban surface soil was sampled based on seven different types of land us...

Heavy metal contamination of soils resulting from mining and smelting is causing major concern due to the potential risk involved. This study was designed to investigate the heavy metal (Cu, Zn, Pb and Cd) concentrations in soils and food crops and estimate the potential health risks of metals to humans via consumption of polluted food crops grown at four villages around the Dabaoshan mine, Sou...

AIM The aim of the study was to investigate antitumor activity of thymoquinone (TQ) and thymohydroquinone (THQ) in vitro and in vivo. MATERIALS AND METHODS In the in vitro experiments, L929 mouse broblasts and two tumor cell lines (squamous cell carcinoma (SCC VII) and fibrosarcoma (FsaR)) were used. The cells were cultured with 0.1 or 0.01 mg/ml TQ or THQ for 24 h, and cytotoxicity assay was...

Purpose To develop a head and neck hyperthermia phased array system compatible with 1.5 T magnetic resonance (MR) scanner for noninvasive thermometry.Methods We designed dielectric-parabolic-reflector antenna (DiPRA) based on printed reflector backed dipole studied its predicted measured performance in flat configuration (30 mm thick water bolus muscle equivalent layer). Thereafter, we applicat...

Health risk assessment of heavy metal contamination in humans through consumption Albula vulpes from Benin River, Koko Town (Southern Nigeria) was studied. Assessment concentrations conducted the liver, kidney and muscles fishes using Atomic Absorption Spectrophotometer. Mean for Zn, Cd, Pb, Mn, As Ni A. were 0.69, 0.20, 0.04, 0.16, 0.13 0.23mg/kg 0.29, 0.08, 0.02, 0.06, 0.05 0.09mg/kg muscle, ...

Heavy metal pollution from industrial wastewaters has become an issue of global concern. These are frequently used for inland irrigation which possess a serious risk heavy contamination both soil and cultivated crops. The problem is more common in developing countries like India where often discharged without appropriate treatments. Therefore, this study aimed at assessing the impact paper mill...

With the occurrence of recreational and small scale subsistence fishing activities at the Vaal Dam, South Africa, consumption of fish from this dam may result in health risks associated with trace elements and metals. The Vaal Dam is one of the largest dams in South Africa, located between the Gauteng Province and Orange Free State, and supplies water to approximately 11.6 million people. A tot...

This study estimated the non-carcinogenic health risk of Pb, Cu, Cd, Zn via dietary intake in urban and rural areas Baia Mare city, northwestern Romania, a former mining area. A total 230 food items grouped ten categories (meat animal organs, meat-derived products, fat, eggs, dairy, bread, corn flour, potato, vegetables, fruits) 32 water samples were collected analyzed for Cd using atomic absor...
