Rapid Screening of Substances of Lower Ecological Concern

Substances Covered Under this Assessment

Substances identified for rapid screening under this assessment are those nominated to the DSL (based on quantities imported, manufactured or otherwise in commerce in Canada in 1986) at total quantities ≤ 1000 kg across the country. Since quantities were reported as ranges, the quantity representing the upper boundary of the reported range was used. If the sum from all notifiers exceeded 1000 kg, the substance was not considered as a candidate for this assessment. Therefore, substances reported in the range 0-100 kg by 10 or fewer companies are included, as well as substances reported in the range 100-1000 kg by a single company.

The substances being assessed have also been identified as PiT(eco) or BiT(eco) through the categorization process. Those substances that were identified by categorization as being PBiT (substances that are persistent and bioaccumulative and inherently toxic to non-human organisms) are excluded from consideration under this assessment, due to particular concerns identified for substances having this combination of properties.

Substances that meet the above criteria, but that have already been assessed and managed under CEPA, are not included. Some other substances have not been included as they are either currently undergoing evaluation or have been identified as priorities for assessment from a human health perspective.

This document reports the results of rapid screening of the 1066 substances that meet the above criteria.
