Characterisation of pollutants washed off from road surfaces during wet weather
This paper presents the results of a monitoring programme carried out to study the washoff of various pollutants from impermeable road surfaces by the runoff produced under artificial and real rainfall conditions. Among the pollution parameters analysed are solids (total, suspended and total volatile), COD (chemical oxygen demand), ammonium and heavy metals (lead, copper, zinc and iron). Analysis of the results indicates a linear relationship between the mass loading rate of total solids, volatile solids and COD. The effect of runoff rate on the magnitude of pollution washed off has also been investigated. Particle size analysis, of the washoff solids shows that the predominant size fraction is < 50 μm. The average diameter of solids has been found to increase with an increase in the runoff rate.
