    en.wikipedia.org/wiki/Emissions_trading

    An early example of an emission trading system has been the sulfur dioxide (SO 2) trading system under the framework of the Acid Rain Program of the 1990 Clean Air Act in the U.S. Under the program, which is essentially a cap-and-trade emissions trading system, SO 2 emissions were reduced by 50% from 1980 levels by 2007.

    en.wikipedia.org/wiki/Organic_peroxides

    The general structure of an organic peroxide. In organic chemistry, organic peroxides are organic compounds containing the peroxide functional group (R−O−O−R′).If the R′ is hydrogen, the compounds are called hydroperoxides, which are discussed in that article.

  5. Homolysis (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Homolysis_(chemistry)

    The O-O σ bond in dibenzoyl peroxide is cleaved homolytically, distributing a radical to each benzoyloxy. Heat Certain intramolecular bonds, such as the O–O bond of a peroxide, are sufficiently weak to spontaneously homolytically dissociate near room temperature. Most bonds homolyse at temperatures above 200°C. [4]

    en.wikipedia.org/wiki/Acid_Rain_Program

    The Acid Rain Retirement Fund (A.R.R.F) is an all-volunteer, non-profit environmental educational organization, incorporated in Maine, dedicated to reducing pollution by purchasing and "retiring" marketable sulfur dioxide emissions allowances issued by the U.S. Environmental Protection Agency’s Acid Rain Program. A.R.R.F. was created in 1995 ...

  7. Acid rain - Wikipedia

    en.wikipedia.org/wiki/Acid_rain

    Acid rain can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Acid rain has been shown to have adverse impacts on forests, freshwaters, soils, microbes, insects and aquatic life ...
