  skos: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'. PCB 24 and PCB 27 is a mixture of two compunds and belongs to the group of persistent organic pollutants known as polychlorinated biphenyls (PCBs)."@en ;
