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 PCB 48 is C12H6Cl4. It is a member of the group of persistent organic pollutants known as polychlorinated biphenyls (PCBs). The IUPAC name is 2,2',4,5-Tetrachlorobiphenyl
