Further Considerations
A release scenario using European monitoring data to determine the effects of concentrations of DNOC in precipitation released to Canadian rivers indicated that there is a low likelihood of risk. This is believed to be a conservative scenario; however, there is significant uncertainty. Studies are in progress in Europe to improve understanding of the extent and mechanisms of formation of DNOC in the atmosphere. As the science evolves or Canadian monitoring data become available, this information could be used in setting priorities on the need for further assessment.
