Contribution of trace metals from atmospheric deposition to stormwater runoff in a small impervious urban catchment.
The contribution of atmospheric deposition to emissions of trace metals in stormwater runoff was investigated by quantifying wet and dry deposition fluxes and stormwater discharges within a small, highly impervious urban catchment in Los Angeles. At the beginning of the dry season in spring 2003, dry deposition measurements of chromium, copper, lead, nickel, and zinc were made monthly for 1 yea...
متن کاملEvaluation of Cancer Risk of Heavy Metals in the Air of a High Traffic Urban Region and Its Source Identification
Background: Sampling was conducted on particles smaller than ten microns (PM10) in a high-traffic urban region once a week for two years in which fifteen heavy metals were measured. Methods: positive matrix factorization (EPA-PMF5), was used for source apportionment and characterization of the collected PM10. Assessment of cancer risk resulting from metals including arsenic, cadmium, chromiu...

متن کاملHeavy metals in bark of Pinus massoniana (Lamb.) as an indicator of atmospheric deposition near a smeltery at Qujiang, China.
GOAL, SCOPE AND BACKGROUND Rapid urbanization and the expansion of industrial activities in the past several decades have led to large increases in emissions of pollutants in the Pearl River Delta of south China. Recent reports have suggested that industrial emission is a major factor contributing to the damages in current natural ecosystem in the Delta area. Tree barks have been used successfu...
متن کاملinvestigating the source of heavy metals in industrial storm basins and atmospheric corrosion
moisture and air pollutions intensify metallic and nonmetallic surface corrosions. corroded surfaces exposed to rain washing cause pollution transportation in water and soil environment, especially in industrial areas. investigation of storm runoff quality in pars special economic energy zone (pseez) has shown heavy metals in storm basins of gas refineries and petrochemical industries.in this p...
