transboundary transport

There is relatively little evidence of transboundary transport elsewhere in the model domain.

Transboundary transport can result in the creation of pollution problems over which a jurisdiction may have little control since the source is outside its boundaries.

• In eastern Canada, transboundary transport plays a major role during smog episodes.

• Long-range transport or transboundary transport of air pollution is a significant problem in Canada.

Longrange transport does occur, but less often than the more local-scale transboundary transport.

Assessment of transboundary transport of air pollutants, acid rain and global air quality are important tasks.

To gain insight into the impacts of transboundary transport of air pollutants, two emission scenarios were derived from the 2000 base case emissions.

Data from the CAPMoN are used to assess transboundary transport of pollutants.

Determine if significant transboundary transport of air pollution occurs in the GB-PS airshed.

Their activities range from Canada-U.S. transboundary transport evaluations to field study campaigns to focused modeling exercises examining the response of models to changes in emissions.

Due to the combination of geography, nature of emissions, and regional wind flow patterns, there is little longer range transboundary transport evident elsewhere in the model domain.

It was recognized that while some solid waste issues were of federal interest (e.g., transboundary transport), most were primarily of provincial and municipal interest.

Canadian and U.S. scientists conducted joint studies to evaluate the transboundary transport potential of PM and its precursors.

Model-calculated interannual variability of concentration, deposition and transboundary transport of anthropogenic sulphur and nitrogen in Alberta.

Some pollutants that reach the Great Lakes through transboundary transport and atmospheric deposition may require action beyond the scope of COA.

By the late 1970s, concerns lead to international efforts to identify the causes and effects of long-range and transboundary transport of air pollutants leading to acid rain.

Justification In case of transboundary transport and storage sites, all Member-States, and the national public, should be effectively involved in the relevant decision-making.

However, ARQM’s R&D also addresses issues that may only affect a particular region of Canada, especially those involving transboundary transport.

The transboundary transport of PM and PM precursors can be significant enough in some regions to potentially compromise the attainment of national standards.

Steel mills have traditionally been regulated by provincial authorities with some federal regulatory requirements, e.g., PCBs and transboundary transport of hazardous wastes.

Furthermore, the results of computer-modeled simulations confirm that there is significant transboundary transport of air pollution in the southern portions of the Georgia Basin airshed.

Local transboundary transport occurs all along the British Columbia/Washington border, particularly in the vicinity of the GVRD and southern Vancouver Island.

The Assessment is intended to synthesize the current state of knowledge on the transboundary transport of fine inhalable particles, in keeping with the information needs of the bi-national policy community.

ARQM scientists were able to use NAtChem to demonstrate that transboundary transport of sulphate and nitrate from the US into Canada is significant.

Significance of Transboundary Transport The Airshed Characterization found that there is sufficient transboundary airflow to transport airborne pollutants across the international boundary.
