Atmospheric Particulate Analysis and Impact of Highway Runoff on Water Quality in Texas

摘要

This experiment was designed to monitor water quality, air quality, traffic, and meteorology along an elevated, impervious section of interstate highway in Dallas, Texas, with a closed storm sewer system. Volume of flow, rainfall, and pollutants discharged were monitored automatically during rainstorms. Particulate was sampled at three locations and subjected to X-ray fluorescent analysis. Particulate levels varied substantially and appeared to decrease sharply after rainshowers. All elements sampled followed the same general pattern of variation with some individual differences. It was difficult to establish a relationship between particulate levels and wind direction. Precipitation seemed to be the most significant factor with a rapid buildup in particulate levels following shower activity.
