Terms for subject Environment (23140 entries)
chloride (A compound which is derived from hydrochloric acid and contains the chlorine atom in the -1 oxidation state) cloruro
chloride-containing drilling muds and wastes fanghi di perforazione e rifiuti contenenti cloruri
chlorinated emulsions emulsioni contenenti composti organici clorurati
chlorinated engine, gear and lubricating oils oli esauriti da motore, trasmissioni ed ingranaggi contenenti composti organici clorurati
chlorinated hydrocarbon idrocarburi clorurati
chlorinated hydrocarbon (A class of persistent, broad-spectrum insecticides that linger in the environment and accumulate in the food chain. Among them are DDT, aldrin, dieldrin, heptachlor, chlordane, lindane, endrin, mirex, hexachloride, and toxaphene. In insects and other animals these compounds act primarily on the central nervous system. They also become concentrated in the fats of organisms and thus tend to produce fatty infiltration of the heart and fatty degeneration of the liver in vertebrates. In fishes they have the effect of preventing oxygen uptake, causing suffocation. They are also known to slow the rate of photosynthesis in plants. Their danger to the ecosystem resides in their rate stability and the fact that they are broad-spectrum poisons which are very mobile because of their propensity to stick to dust particles and evaporate with water into the atmosphere) idrocarburi clorurati
chlorinated hydrocarbons idrocarburi clorurati
chlorinated paraffins cloroparaffina

chlorination clorurazione
chlorination (The application of chlorine to water, sewage or industrial wastes for disinfection or other biological or chemical purposes) clorurazione

chlorinator cloratore
chlorine (A very reactive and highly toxic green, gaseous element, belonging to the halogen family of substances. It is one of the most widespread elements, as it occurs naturally in sea-water, salt lakes and underground deposits, but usually occurs in a safe form as common salt (NaCl). Commercially it is used in large quantities by the chemical industry both as an element to produce chlorinated organic solvents, like polychlorinated biphenyls (PCBs), and for the manufacture of polyvinyl chloride plastics, thermoplastic and hypochlorite bleaches. Chlorine was the basis for the organochlorine pesticides, like DDT and other agricultural chemicals that have killed wildlife. The reactivity of chlorine has proved disastrous for the ozone layer and has been the cause of the creation of the ozone hole, which was first detected in the Southern Hemisphere over Antarctica and then over the Northern Hemisphere) cloro
