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. "Gas and particle" means a system consisting of both gas and suspended liquid or solid particles in air (except cloud droplets). PCB 163 and PCB 138 is a mixture of two compunds and belongs to the group of persistent organic pollutants known as polychlorinated biphenyls (PCBs).
