Risk Assessment of Priority Substances |
|
Environment Canada, 1997-2000 |
|
In the years of 1989 and 1995, Environment Canada and Health Canada established
two lists of priority substances for assessment of their associated risk to human
health and the environment. Crechem was given a number of tasks to assist Environment
Canada in risk assessment of four priority substances included in the second list (PSL2),
acrylonitrile, ethylene oxide, ethylene glycol, and textile mill effluents. Crechem
developed a process-based engineering approach to release estimation. The approach was
validated with industry data and provided an independent source of release data
for cases where direct measurements were not possible.
