SOURCE:
Environment Canada 2001. The National Pollutant Release Inventory
(NPRI) 2000. NOTES: In 1996, NPRI included by-products resulting
in more pollutants being included in the inventory than previous
years. In 1998, changes in reporting techniques for electrical utilities
increased reported releases from previous years. Newly reported
substances include 73 substances added to the inventory in 1999
and 4 new substances in 2000. The 2000 analysis does not include
mercury and 19 new substances added in 2000, because they were reported
at alternate thresholds. Acetone was removed from the inventory
in 1999. NPRI on-site toxic waste releases is not an indicator of
all pollutants entering the environment. Other substances such as
greenhouse gases or pesticides and substances scheduled for ban
or phase-out (e.g., chlorofluorocarbons and PCBs) are not included
on the list. In addition, not all sources of NPRI pollutants are
captured by the inventory.
