Specific foods such as fish and rice have high concentrations of metals such as arsenic, mercury, lead, cadmium, and cobalt. Many gluten-free diets (GFDs) include these foods, so we evaluated whether a GFD was associated with increased metal bioaccumulation. We performed a population-based, cross-sectional study using data collected from the Nation...
Arsenic, lead, and cadmium are among the EPA’s highest priority hazardous substances for research and remediation. These toxic elements are high priorities due to extensive soil and water contamination, and extreme impact on human health, including increased cancer rates, liver disease, respiratory disorders, and learning disabilities. As part of m...
Heavy metal soil pollution from anthropogenic sources such as historical use of fertilizers, poor waste disposal, and spills from industries are a serious environmental problem. This can be especially damaging in developing countries where incentives are limited to remediate these soils, and some of the poorest regions are the most affected. Soil r...
The San Francisco Bay has the largest concentration of salt marshes in the state of California, representing a diversity of marsh habit. Protecting these environments is critical, as salt marshes provide refuge to endangered species, absorb carbon from the atmosphere, and preserve detailed evidence of past climatic, hydrologic, geomorphic, and ecol...

We investigated the effects of initial pH (2≤pH0≤6) and sewage sludge compost content (5≤[SSC]≤25 g/kg) on leaching characteristics of lead (Pb) and zinc (Zn) in contaminated field soil. pH0 and [SSC] significantly affected the leaching of Pb and Zn in soils contaminated with them. The pH in the solution increased as reaction time and [SSC] increas...

A simple, efficient and cost effective method was developed and optimized for the digestion of fish tissue for the determination of Lead, Cadmium, Mercury, Antimony, Arsenic and Selenium by FAAS, CVAAS and HGAAS. Three of the more common classical open tubed acid digestion procedures were explored with the purpose of optimizing the variables and se...
The present study aims to determine the presence of cadmium and lead heavy metals in the Chone River estuary; Ecuador, during June to September 2014, six water samples and five soil samples were obtained at six sites, with two replications per site giving a total of 66 samples. The analysis was performed according to the protocol of Merck-Millipore...

The ability of nano-ZrO2 and modified nano-ZrO2 with humic acid (ZrO2-H) to remove Cd2+, Cu2+ and Ni2+ from aqueous media has been tested by batch sorption studies varying the contact time, initial metal concentration, initial solution pH, sorbent dosage and temperature to understand the adsorption behavior of these metals through adsorption kineti...

BackgroundHeavy metals, which constitute a major public health concern, are known to accumulate in food and fruits during plants growth. Fruits which are readily consumed because of their characteristic sweet taste and potential health benefits stand a major risk of heavy metal intoxication. Hence, this study assessed some fruits commonly sold in E...
