Coal dust risk

A study has found that concentration of coal dust can quickly kill coral on Australia’s Great Barrier Reef. Australian Institute of Marine Science discovered coal dust could also slow the growth rate of seagrasses and fish, Xinhua news agency reported. “Corals exposed to the highest concentrations of coal dust died within two weeks,” author Kathryn Berry said. “Corals exposed to lower concentrations of coal lasted longer, but most of them also died after four weeks of exposure.”  She noted that while some fish and seagrass died from coal dust exposure, it mostly stunted their growth.
