Environmental mercury contamination around a chlor-alkali plant

Chlor-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...

Mercury speciation in the hair of pre-school children living near a chlor-alkali plant.

Exposure to mercury species was assessed in the hair of 130 Spanish children (age 4) from the general population in two areas. Both areas are exposed to different sources of mercury: a point source in Ribera d'Ebre (northeastern Spain) and a diffuse source on the island of Menorca (northwestern Mediterranean). The median MeHg values in the hair of children from Ribera d'Ebre (RE) were nearly tw...

Effects of Mercury in Brine on the Performance of the Membrane-Type Chlor-Alkali Plant

of high quality at high concentration (2,3). The performance of the membrane-type chlor-alltali plant mainly depends on the cell design, the membrane, the quality of feed brine, and operating conditions. Of these, the brine quality is the key factor affecting the service life and the performIn the case of conversion from amalgam to membrane process, it is important to elucidate the effects of m...

Health effects associated with long-term occupational exposure of employees of a chlor-alkali plant to mercury.

This study aimed to evaluate possible health effects associated with long-term occupational exposure to low levels of mercury vapors. Forty-six subjects exposed to mercury and 65 healthy unexposed employees were studied. The subjects were administered a questionnaire on experienced symptoms and underwent clinical examinations as well as routine biochemical tests. Atmospheric and urinary concent...
