The Effect of Paved Roads on Organic Carbon Content of Soil in Taham Dam Basin
Background; Contamination of water and soil through non-point sources such as road runoff causes environmental concern. The aim of this study is to determine the effect of Zanjan – Chavarzagh road on the total organic carbon (TOC) content of sediments in tributaries and the river that lead to Taham Lake. Methods; In tributaries and the river 69 soil and sediment samples were taken and the Tota...
متن کاملRegional analysis of the effect of paved roads on sodium and chloride in lakes.
Salinization of surface water from sodium chloride (road salt) applied to paved roads is a widely recognized environmental concern in the northern hemisphere, yet practical information to improve winter road management to reduce the environmental impacts of this deicer is lacking. The purpose of our study was to provide such information by developing baseline concentrations for sodium and chlor...
متن کاملImplementation of resuspension from paved roads for the improvement of CALIOPE air quality system in Spain
Emissions of resuspensed particles from paved roads (RPR) have received an increasing attention in air quality modeling, since chemistry transport models are generally unable to reproduce particulate levels near road traffic. However, among the models operated in the forecasting mode in Europe, there is a lack of systems including the contribution of RPR on an hourly basis. Therefore, this cont...
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 کاملCharacterization of Mud/Dirt Carryout onto Paved Roads from Construction and Demolition Activities
Several urban areas of the country in violation of the National Ambient Air Quality Standard (NAAQS) for particulate matter have identified fugitive dust generated by vehicular traffic on paved streets and highways resulting from mud/dirt carryout from unpaved areas as a primary source of PM-10 (particles ≤ 10 μm in aerodynamic diameter). Since little data are currently available on the amount ...
