A chemical factory accidentally releases 1000 kg of naphthalene into a nearby river. The river has an average flow rate of 1,000,000 m/day, and the naphthalene is assumed to be uniformly distributed to water, soil and air. The default volumes for the air, soil, and water compartments in the volumetric model are 10^6 m^3, 10^6 m^3, and 10^6 m^3, respectively. Naphthalene's half-life in water is 1-2 days due to photolysis and 2-3 days due to biodegradation.Naphthalene's half-life in soil is 3 months due to biodegradation. Naphthalene evaporates from the water surface and affects the air, with a half-life of 7 days due to photolysis. Report the mass and concentration of the contaminant in each environmental media calculated by the model (Tables, figures generated by the model)
