    Particulate pollution is pollution of an environment that consists of particles suspended in some medium. There are three primary forms: atmospheric particulate matter, [1] marine debris, [2] and space debris. [3] Some particles are released directly from a specific source, while others form in chemical reactions in the atmosphere.

    en.wikipedia.org/wiki/Global_dimming

    v. t. e. Global dimming is a decline in the amount of sunlight reaching the Earth's surface. [2] [3] It is caused by atmospheric particulate matter, predominantly sulfate aerosols, which are components of air pollution. [4] Global dimming was observed soon after the first systematic measurements of solar irradiance began in the 1950s.
