A substance that increases the hydrogen ion concentration in a solution.
Industry:Natural environment
The fan-shaped area at the mouth or lower end of a river formed by eroded material that has been carried downstream and dropped in quantities larger than can be carried off by tides or currents.
Industry:Natural environment
A gaseous molecule that contains three oxygen atoms (O3), instead of the usual two (O2). Ozone can exist either high in the atmosphere (stratosphere), where it shields the Earth against harmful ultraviolet rays from the sun, or close to the ground (troposhere), where it is the main component of smog. Ground-level ozone is a product of reactions involving hydrocarbons and nitrogen oxides in the presence of sunlight. Ozone is a potent irritant that causes lung damage and a variety of respiratory problems.
Industry:Natural environment
A molecule that is capable of reacting with free radicals and neutralizing them; a compound that slows the rate of oxidation reactions.
Industry:Natural environment

Industry:Natural environment
A metal having a specific gravity of 5.0 or greater. Heavy metals are generally toxic to organisms in relatively low concentrations, and tend to accumulate in the food web. Examples include arsenic, cadmium, chromium, lead, and mercury .
Industry:Natural environment
In genomics, a key component of DNA and RNA molecules. Four different bases are found in DNA: adenine (A), cytosine (C), guanine (G) and thymine (T). In RNA, uracil (U) substitutes for thymine; also known as nitrogenous bases; a base, a phosphate molecule and a sugar joined together constitute a nucleotide.
Industry:Natural environment
