  • Measurement of cyanide in urban snowmelt and runoff

    Ferrocyanide compounds enter the environment as anti-caking additives to road salts. In illuminated aquatic environments, the salts dissociate and form toxic free cyanide, which can then be lost through volatilization. The most common techniques for analysis of cyanide in environmental samples measure total and free (generally weak-acid dissociable, WAD) cyanide species. Cyanide has been detected ...

  • The influence of particle size on the first flush strength of urban stormwater runoff

    The presence of a first flush (FF) of suspended solids (SS) in stormwater runoff has important implications for the design of treatment facilities, as does the particle size of solids. Whilst numerous studies have examined the FF behaviour of SS, few have disaggregated FF trends by particle size. In this study, the FF behaviour of SS was investigated in five size ranges, sampled from an urban ...
