Object Of Interest: PCB 200
Observation Matrix: gas and particle phase
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). The chmical formula for PCB 200 is C12H2Cl8. It belongs to the group of persitent organic pollutants (POPs) known as polychlorinated biphenyls (PCBs). The IUPAC name is 2,2',3,3',4,5,6,6'-Octachlorobiphenyl
