Carbon dioxide solvents such as organochlorides. It is used by some dry cleaners for this reason (see green chemistry). It is used in the preparation of some aerogels because of the properties of supercritical carbon dioxide. Plants require carbon dioxide to conduct photosynthesis. The atmospheres of greenhouses may (if of large size, must) be enriched with additional to sustain and increase the rate of plant growth. At very high concentrations (100 times atmospheric concentration, or greater), carbon dioxide can be toxic to animal life, so raising the concentration to 10,000 ppm (1%) or higher for several hours will eliminate pests such as
Ocean storage of carbon dioxide atmosphere, the resulting change in ocean pH would also be similar as ocean mixing would eventually absorb excess carbon dioxide. Dilute carbon dioxide injection requires injection at depths where carbon dioxide can be dispersed by ocean currents and ocean mixing. Upon injection, waters interact and mix based on density and dilute the concentration of carbon dioxide. Boat based carbon dioxide injection distributes low carbon dioxide concentrations in open waters while moving to increase carbon dioxide dispersal area. carbon dioxide dispersal via boat can also occur by a pipe attached to the ship injecting a dilute carbon dioxide mixture into the
