definition: Mass concentration means mass per unit volume and is used in the construction mass_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 4 and PCB 10 is a mixture of two compunds and belongs to the group of persistent organic pollutants known as polychlorinated biphenyls (PCBs).
