Chromium: Origin, products, applications and health implications

Chromium, which is used in stainless steel, colorants and corrosion management in cooling systems, has been regulated for its potential health implications.

Ingestion health issues

Chromium became an issue again in the 1990s resulting from local groundwater contamination caused by uncontrolled discharges of cooling water containing chromium (VI) from an electrical generating facility in California. Total chromium, and chromium (VI) have been regulated in drinking water since 1946 in the U.S. Public Health Service (PHS) standards at 50 µg/L (50 ppb). Chromium (III) is considered to be innocuous and a possible essential nutrient. The PHS concluded that although there was agreement that ingested chromium VI was probably not carcinogenic, the regulations assumed that the standard and water concentration could even be all chromium (VI).

Wastewater disposal requirements for pharmaceutical manufacturing

Pharmaceutical chemicals are designed to be biologically active, so the disposal of their waste products receives regulatory scrutiny in many countries.

January 4, 2019 (Water Tech)

About 10,000 pharmaceuticals with about 3,000 active ingredients are approved and marketed in the U.S. These and their reaction byproducts, reactants and solvents can be present in waste streams that require treatment prior to direct or indirect discharges. Pharmaceutical production is a major portion of the chemicals manufacturing industry — in value and product diversity, if not in gross tonnage. Because pharmaceutical chemicals are designed to be biologically active, it is not surprising that disposal of their production waste products into the environment receives particular regulatory scrutiny in many countries. That could be one of the reasons why many pharmaceuticals are now manufactured outside the U.S., usually in Asia under less stringent regulatory conditions; fewer regulatory controls contribute to lower production costs as well as additional contamination.
