Fugitive dust emissions from paved road travel in the Lake Tahoe basin.
The clarity of water in Lake Tahoe has declined substantially over the past 40 yr. Causes of the degradation include nitrogen and phosphorous fertilization of the lake waters and increasing amounts of inorganic fine sediment that can scatter light. Atmospheric deposition is a major source of fine sediment. A year-round monitoring study of road dust emissions around the lake was completed in 200...
متن کاملVehicle-Based Road Dust Emissions Measurements
TRAKER is a vehicle-based method for measuring road dust emissions. Particulate matter is sampled in front and behind a vehicles tire and the difference in PM concentration (TRAKER signal) is used to infer the airborne flux of particles from the roadway. Two independent tests indicated that the TRAKER signal increases as the cube of the speed for a given road dust loading. Simultaneous measure...
متن کاملMeasurement of PM10 Emission Factors from Paved Roads Using On-Board Particle Sensors
Based on emission factors derived from the AP-42 algorithm, particulate matter from paved roads has been estimated to be a major source of PM10 of geologic origin. This is an empirical formula based on upwind-downwind measurement of PM10 concentrations and is dependent solely on the silt loading of the pavement and the weight of vehicles. A number of upwind-downwind studies conducted in urban a...
متن کاملA comprehensive assessment of PM emissions from paved roads: real-world Emission Factors and intense street cleaning trials.
Compliance with air quality standards requires control of source emissions: fine exhaust particles are already subject to regulation but vehicle fleets increase whilst the non-exhaust emissions are totally uncontrolled. Emission inventories are scarce despite their suitability for researchers and regulating agencies for managing air quality and PM reduction measures. Only few countries in Europ...
متن کاملLong-Term Efficiencies of Dust Suppressants to Reduce PM10 Emissions from Unpaved Roads.
A 14-month study was undertaken to assess the long-term efficiencies of four dust suppressants (i.e., biocatalyst stabilizer, polymer emulsion, petroleum emulsion with polymer, and nonhazardous crude-oil-containing materials) to reduce the emission of PM10 from public unpaved roads. PM10 emission rates were calculated for each test section and for an untreated section for comparison purposes. E...
