Mercury (element) polluted water. They arise by a process known as biomethylation. Mercury is used primarily for the manufacture of industrial chemicals or for electrical and electronic applications. It is used in some thermometers, especially ones which are used to measure high temperatures. A still increasing amount is used as gaseous mercury in fluorescent lamps, while most of the other applications are slowly phased out due to health and safety regulations and is in some applications replaced with less toxic but considerably more expensive Galinstan alloy. Mercury and its compounds have been used in medicine, although they are much less common today
Centre for Fire, Explosive and Environment Safety processing and storage dumps and the design, testing and evaluation of safe explosive storage houses. Additionally, it trains armed forces personnel and DRDO scientists in the safe use of explosives and ordnance, and enforces compliance of safety rules. Simulation and risk modeling is also carried out, in order to aid in Disaster Management. Environment Safety - CFEES develops treatment and disposal techniques for hazardous Heavy Metal Wastes, as well as Photodegradable Polyethylene for use as packaging material at high altitudes, which prevents the pollution in mountainous areas where the Indian Army operates, such as Kargil and Siachen. CFEES also plays
