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 dibenzo(a,l)pyrene is C24H14. It belongs to the group of polycyclic aromatic hydrocarbons (PAHs). The IUPAC name is hexacyclo[10.10.2.02,7.08,24.015,23.017,22]tetracosa-1(23),2,4,6,8,10,12(24),13,15,17,19,21-dodecaene
