definition: Number concentration means number of molecule per unit volume, and is used in the construction molecular_concentration_of_X_in_Y, where X is a material constituent of Y. A chemical species denoted by X may be described by a single term such as 'nitrogen' or a phrase such as 'nox_expressed_as_nitrogen'. The chmical formula for p,p-DDD is C14H10Cl4. It is a member of the group of persistent organic pollutants (POPs). The IUPAC name is 1-chloro-4-[2,2-dichloro-1-(4-chlorophenyl)ethyl]benzene
