    In addition, atmospheric deposition may be a significant source of environmental contaminants such as trace metals and toxic organic compounds. Results of the National Atmospheric Deposition Program/National Trends Network indicate that Maryland is in or near the region of most acidic precipitation and receives some of the highest

    Assessment of atmospheric trace metal deposition in urban

    The objective of this paper is to assess wet and dry atmospheric depositions on a small urban watershed using two methods to measure dry deposition: 1) the so-called “indirect method”, i.e.the subtraction of wet deposition (collected with an automated rain collector) from bulk deposition determined from a polyethylene container; and 2) the

    The dry Deposition and Resusepnsion of Particle-Associated

    Dry atmospheric deposition represents a potentially large source of trace metal contamination in urban stormwater runoff, yet there is a limited amount of research on the relationship between atmospheric emissions and water quality problems in urban areas. In Los Angeles, which has among the worst air quality in the nation, significant quantities of toxic materials are released into the

    High-mobility graphene on liquid p-block elements by ultra

    The high-quality and low-cost of the graphene preparation method decide whether graphene is put into the applications finally. Enormous efforts have been devoted to understand and optimize the CVD

    Large-Area WS 2 Film with Big Single Domains Grown

    High-quality WS2 film with the single domain size up to 400 μm was grown on Si/SiO2 wafer by atmospheric pressure chemical vapor deposition. The effects of some important fabrication parameters on the controlled growth of WS2 film have been investigated in detail, including the choice of precursors, tube pressure, growing temperature, holding time, the amount of sulfur powder, and gas flow rate.
