Predicting Event-Based Sediment and Heavy Metal Loads in Untreated Urban Runoff from Impermeable Surfaces

Pollution loads in urban runoff and sanitary wastewater.

While more attention has been paid in recent years to urban point source pollution control through the establishment of wastewater treatment plants in many developing countries, no considerable planning nor any serious measures have been taken to control urban non-point source pollution (urban stormwater runoff). The present study is a screening analysis to investigate the pollution loads in ur...

Suspended Solids In Stormwater Runoff From Various Urban Surfaces

Suspended Particle Characteristics in Storm Runoff from Urban Impervious Surfaces

Spatial distribution and degree of heavy metal pollution in urban roadside dusts from Sanandaj, Iran

Industrial activities and high traffic density are the most important heavy metal pollution sources in urban areas. Roadside dust created by atmospheric deposition can be one of the best indicators for heavy metal contamination levels. The present study reports the spatial distribution patterns and degree of heavy metal pollution (Cd, Cr, Ni, Pb, Zn, and As) in 50 roadside dust samples from urb...

An Innovative Method for Spatial Quantification of Contaminant Buildup and Wash-off from Impermeable Urban Surfaces

A method was developed that employs thin boards (0.56 m) comprising different paving materials (2 asphalt types and concrete) typically used in urban environments. Boards can be placed at various locations of interest within an urban catchment to investigate accumulation of contaminants over specified periods of time. Boards are then placed under a rainfall simulator in order to generate runoff...
