Thallium (Tl) is widely used in various industries, which increases the risk of leakage into the environment. Since Tl is highly toxic, it can do a great harm to human health and ecosystem. In order to explore the response of freshwater sediment microorganisms to sudden Tl spill, metagenomic technique was used to elucidate the …

The most studied case of coal ash damage occurred at Belews Lake in North Carolina in the 1970s, when coal ash-contaminated water from an ash pond at Duke Energy's Belews Creek Steam Station caused a long-term catastrophic toxic event. Selenium poisoning killed 19 of the 20 fish species in 3800-acre Belews Lake.

Hexavalent chromium, or Chromium VI, is a carcinogen if inhaled and can result in an increased risk of lung cancer. Total chromium is regulated by the Safe Drinking Water Act and has a Maximum Contaminant Level in drinking water of 0.1 milligrams per liter (mg/l) or 100 parts per billion (ppb) . 3. What about Ann Arbor's drin king water?

Thallium, cadmium, lead and copper. Using voltammetric measurements in DCs, the thallium peak was anticipated of ca. 30 mV, in comparison with non-saline solutions, as a consequence of thallium chlorocomplex formation (log K f = 0.52). 24 Similarly, anticipations of ca. 60, 50 and 150 mV were observed by individual measurements in the …

Preliminary analysis indicates a change with time in nickel (Ni), chromium (Cr), and lead (Pb) concentrations in sea bottom sediment samples which were collected during the falls of 2009, 2010, and 2011 along the continental shelf of the Eastern Gulf of Mexico. These samples bracket the Deepwater Horizon Oil Spill which occurred during …

6. Application of Chromium, Arsenic, Antimony, and Thallium Speciation Analyses in Bottom Sediment Samples. The high chromium content in bottom sediments is often caused by the close vicinity of tanneries, steelworks, or galvanic shops. The tanning industry is a typical source of Cr(III), including mainly sulphates . Under the redox and ...

Chromium is one of the most popular metals in the world. Chromium is a silvery, lustrous, hard, and brittle metal known for its high mirror polish and corrosion resistance. It has a melting point of 1,857°C, a density of 7.2 g/cc, and a vapor pressure of 10-4 Torr at 1,157°C. Its name comes from the Greek word "chroma", which means color, due ...

Thallium, a soft, bluish-gray, malleable heavy metal, was discovered by Sir William Crookes in 1861 while he was making spectroscopic determinations for tellurium on residues from a sulfuric acid plant. Although the metal is reasonably abundant in the Earth's crust at a concentration estimated to be about 0.7 part per million, it exists mostly in …

Chromium. Chromium is a grayish-white metallic element commonly occurring in nature. Chromium is used in electroplating, alloy metals, and as a corrosion inhibitor in the textile, glass, and photographic industries. Potential sources of contamination in drinking water include discharge from steel and pulp mills and erosion of natural deposits.
