Metal-on-metal (MoM) prostheses, in which the bearing surfaces are made of a metal alloy, may release metal ions upon wear and corrosion, potentially inducing both local and systemic toxicity. As the systemic cobalt concentration increases with the degree of implant wear, this concentration needs to be monitored as a means of assessing implant func...
This research focused on the contents of the five most bio-toxic heavy metals, As, Cd, Hg, Cr, and Pb of 26 municipal solid waste (MSW) samples from the Eastern Guangdong Area. To investigate the apportion of the heavy metal source, Pearson correlation and principal component analysis (PCA) were introduced as major approaches. The health risks pose...

China is one of the largest producers, consumers, and emitters of cadmium (Cd). This study applies the methods of material flow analysis and inventory analysis to investigate the flows and stocks of Cd in the industry-environment system in mainland China from 1990 to 2015. Special attention is paid to the identification of emissions and correspondi...
Activated carbon (AC) has the advantage of multi-pollutant control with a high removal efficiency for flue gas purification. It is necessary to determine the oxidation mechanism and oxidation products of hydrogen sulfide (H2S) on AC to simultaneously capture H2S and SO2. A fixed-bed reactor was coupled with a mass spectrometer (MS) to detect the ga...

Lead is a ubiquitous dietary contaminant that occurs in food because of natural and anthropogenic sources and pathways of exposure. Lead adversely affects a number of tissues and organ systems and the severity of effect on each is dependent on the level and duration of exposure. The most sensitive and notable effects are those that occur on the ner...
Mercury (Hg) is a toxic metal subject to several international regulations. The European Water Framework Directive (WFD) established in 2008 an Environmental Quality Standard for biota (EQSbiota) at 0.02 µg.g.
Calorimetric and fluorimetric detection of toxic metal ions such as Hg2+ and Cr3+ has gained tremendous popularity over the conventional methods due to their operational simplicity, high selectivity, and speediness. Although numerous colorimetric and fluorescent receptors for Hg2+ or CO3+ were reported in the literature, boronic acid-based receptor...
