Analysis of Unit Pollution Load on Highway runoff

Assessment of treatment systems for highway runoff pollution control in Portugal.

Treatment systems for highway runoff pollution control are now common structures for environmental impacts reduction in Portugal. Such systems must be monitored and its performance periodically assessed, in order to understand if they are accomplishing the targets for environmental protection. Wise management decisions must incorporate the soundness of the project, the construction and maintena...

Development and Evaluation of Best Management Practices (bmps) for Highway Runoff Pollution Control

The contribution of heavy metal pollution derived from highway runoff to Guanabara Bay sediments--Rio de Janeiro/Brazil.

In this study, geochemical and particle size analyses of thirty-four street sediment samples collected from an urban environment around Guanabara Bay, shows highway run-off to be a potential source of heavy metals for the pollution of near-shore sedimentary deposits. Concentrations of Fe, Mn, Zn, Cu, Pb, Cr and Ni were found to be higher in these sediments when compared to concentrations found ...

Toxicity of urban highway runoff with respect to storm duration.

The toxicity of stormwater runoff during various time-based stages was measured in both grab and composite samples collected from three highly urbanized highway sites in Los Angeles, California between 2002 and 2005. Stormwater runoff samples were tested for toxicity using three freshwater species (the water flea Ceriodaphnia dubia, the fathead minnow Pimephales promelas, and the green algae Ps...

Bacterial Pollution in Runoff from Agricultural Lands

A review of the literature reporting the methods and results of studies concerned with the nature of nonpoint source microbial pollution leads to several conclusions: (i) Comparison f data from different studies may be complicated by variation in the choice of indicator organisms, variation in watershed size and homogeneity, and variation in media and procedures for determining fecal streptococ...
