Observational Study of Content of Heavy Metals in Fog Water Relative to Air Pollution in Suburbs of Nanjing

Study is conducted of heavy metals of fog water and air pollution in foggy weather. Results show that foggy weather condition prevents the diffusion of pollutants leading to heavy contamination, with change in pollutant density approximately in phase with fog genesis/lysisiquestone-to-one correlation analysis between densities of heavy metals (Cd, Cr, Cu, Mn and Fe except As) and pollutants shows the coefficients to be above 0.96, with correlation of total weight of heavy metals to CO2 concentration reaches 0.9735, thereby indicating homology.
