Mercury from chlor-alkali plants: measured concentrations in food product sugar
Mercury cell chlor-alkali products are used to produce thousands of other products including food ingredients such as citric acid, sodium benzoate, and high fructose corn syrup. High fructose corn syrup is used in food products to enhance shelf life. A pilot study was conducted to determine if high fructose corn syrup contains mercury, a toxic metal historically used as an anti-microbial. High ...
متن کاملEstimating distribution and retention of mercury in three different soils contaminated by emissions from chlor-alkali plants: part I.
Mercury emissions from chlor-alkali plants have been past and present sources of soil contamination with Hg. Here we calculate net mercury (Hg) deposition to soils in the vicinity (100-1000-m downwind) of three-chlor alkali plants. Calculations were based on spatial distribution patterns of Hg concentrations in soils, which were extrapolated by kriging. Moreover, we investigated to what extent ...
متن کاملA multidisciplinary and multifactorial integrated approach for the understanding of the problem of the atmospheric mercury pollution
In the last decades the awareness of scientists, decision makers and citizens about the ubiquitous and toxic nature of mercury in the environment has considerably grown. The complexity of the environmental problem related to mercury is increased because of the volatile nature of this metal, which results in global dispersion through the atmosphere and deposition in the sea and freshwater bodies...
متن کاملMercury speciation in highly contaminated soils from chlor-alkali plants using chemical extractions.
A four-step novel sequential extraction procedure (SEP) was developed to assess Hg fractionation and mobility in three highly contaminated soils from chlor-alkali plants (CAPs). The SEP was validated using a certified reference material (CRM) and pure Hg compounds. Total, volatile, and methyl Hg concentrations were also determined using single extractions. Mercury was separated into four fracti...
متن کاملChlor-alkali Plant Contributes to Mercury Contamination in the Savannah River
For many years the Savannah River has suffered fish consumption warnings. While several potential sources of mercury may contribute to this contamination, the chlor-alkali facility in Augusta, which produces chlorine by electrolysis using mercury-cell technology, is a major potential contributor. To examine this possibility samples of sediment were collected from the river above and below the f...
