Ethylene is a gaseous plant hormone involved in many aspects of the plant life cycle, as well as in response to external stress. In the broadest of terms, ethylene is responsible for signalling changes during seed germination, growth, flower and fruit development, senescence of plant organs, programmed cell death, etc.
Hydrogen Fluoride (HF) is a common industrial compound used in various applications, such as the manufacturing of fluorine, superacids, refrigerants, pharmaceuticals and polymers, in glass etching, stainless steel pickling, silicon semiconductor chip production, the automotive industry, etc. HF is non-flammable, highly corrosive and very toxic and has a strong, irritating odour. To ensure final product quality and reduce waste, the HF concentration...
Everyone is regularly exposed to various levels of ammonia in air, soil, water, and food. Most of ammonia released to the environment comes from the degradation of animal waste and industrial processes (e.g. in chemical plants).It is one of the contributors to soil acidification and 'acid rain', playing an important role in the long range transport of the acidic pollutants and formation of aerosols in the atmosphere.
Nitrous oxide (N2O) plays an important role as greenhouse gas and is involved in the depletion of the ozone layer in the atmosphere. The world wide N2O increase is generally caused solely by the anthropogenic sources.
