The effect on the rate of tumor induction of a group of chlor-compounds which reversibly inhibit the glycolyric process of cells has already been described (5, 6). The compounds used were soluble in water and fats, and were nonhydrolyzable under physiological conditions of pH and temperature. The chemical reactivity of their chlorine atoms was the factor which determined the potency of their bi...

Former industrially contaminated sites are a burden from the past that still pose environmental risks. During second half of 20th century, Pavlodar region in North Kazakhstan had been part Soviet Union’s industrial system operated chlor-alkali plant (CAP). The former CAP discharged approximately 135 t Hg into nearby Lake Balkyldak with total losses to water, soil, and air estimated around 1000 ...

In situ air concentrations of gaseous elemental mercury (Hg(0)) and vegetation–atmosphere fluxes were quantified in both high (Cala Norte, CN) low-to-moderate (Alcochete, ALC) Hg-contaminated saltmarsh areas the Tagus estuary colonized by plant species Halimione portulacoides (Hp) Sarcocornia fruticosa (Sf). Atmospheric Hg(0) ranged between 1.08–18.15 ng m−3 CN 1.18–3.53 ALC. CN, most levels oc...

The emission of inorganic divalent reactive gaseous mercury (RGM) from a mercury cell chlor-alkali plant (MCCAP) cell building and the impact on near field (100 km) dry deposition was investigated as part of a larger collaborative study between EPA, University of Michigan, Oak Ridge National Laboratory, Chlorine Institute, and Olin Corporation in February 2000. Measurements in the cell building...

This study focussed on a comparison of the extractability of mercury in soils with two different contamination sources (a chlor-alkali plant and mining activities) and on the evaluation of the influence of specific soil properties on the behaviour of the contaminant. The method applied here did not target the identification of individual species, but instead provided information concerning the ...

The previously widespread mercury cell technology in chlorine production has now been replaced by more environmentally friendly membrane electrolysis which is a Best Available Techniques (BAT) technology. However, this requires much cleaner brine containing contaminants (Al, Ca, Mg, etc.) the order of ng/g at most. For reason, it’s very important to detect trace amounts aluminum concentrated sa...

Brines generated from oil and natural gas production, including flowback water and produced water from hydraulic fracturing of shale gas, may contain elevated concentrations of bromide (~1 g/L). Bromide is a broad concern due to the potential for forming brominated disinfection byproducts (DBPs) during drinking water treatment. Conventional treatment processes for bromide removal is costly and ...

In this study, an electrochemical sensor for the monitoring of Hg (II) at trace levels by using differential pulse anodic stripping voltammetry has been reported. Basically is a Phanerochaete chrysosporium-based carbon paste electrode. Here, chrysosporium played new vital role in detection heavy metal apart from its known contribution their removal. Optimal voltammetric response was observed −0...
