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 detect...
متن کاملSnowmelt Runoff: A New Focus of Urban Nonpoint Source Pollution
Irregular precipitation associated with global climate change had been causing various problems in urban regions. Besides the runoff due to rainfall in summer, the snowmelt runoff in early spring could also play an important role in deteriorating the water quality of the receiving waters. Due to global climate change, the snowfall has increased gradually in individual regions, and snowstorms oc...
متن کاملMineral and Anthropogenic Indicator Inorganics in Urban Stormwater and Snowmelt Runoff: Sources and Mobility Patterns
Inorganic chemicals in urban stormwater and snowmelt runoff originate from catchment geology and anthropogenic activities. The occurrence, partitioning and mobility of six minerals and six trace metal (TM) indicators of anthropogenic activities were studied in stormwater, snowmelt and baseflow in four urban catchments, and the sampling of inorganics was supplemented by measurements of electrica...
متن کاملEffects of suburbanization upon snowmelt runoff
The influence of suburbanization upon runoff response to snowmelt and rain-on-snow inputs was examined for a small drainage basin in south-central Ontario. Modification of more than 50% of the basin area over a 14 year period led to a six-fold increase in the spring quickflow response ratio and an increase in the number of snowmelt events that generate appreciable quickflow. Anticipated changes...
متن کاملPossibilistic uncertainty analysis of a conceptual model of snowmelt runoff
This study presents the analysis of predictive uncertainty of a conceptual type snowmelt runoff model. The method applied uses possibilistic rather than probabilistic calculus for the evaluation of predictive uncertainty. Possibility theory is an information theory meant to model uncertainties caused by imprecise or incomplete knowledge about a real system rather than by randomness. A snow domi...
