The Green Lane: Acid rain - What's New
Between 21 and 75 percent of eastern Canada, continues to receive levels of acid deposition in excess of critical loads ( i.e. the amount of acid deposition that a particular region can receive without being adversely affected). There is potential for acid deposition to affect the long-term sustainability of Canada's ecosystems. It is ...

The Green Lane: Acid rain
For now, forests in affected areas - where acid rain exceeds the critical loads - are using the pool of minerals accumulated during post-ice age times, although some ... acid deposition that a region can receive without damage to its ecosystems is known as its critical load. It depends essentially on the acid-rain neutralizing capacity of the water, rocks, and ...

ESSP CLP - Principles and Practices in Sustainable Development for the Engineering and Built Environment Professions Unit1 Lecture 3
Sulphur Protocol is an example of what could be done for all major pollutants. The environmental objective of the Second Sulphur Protocol - to eventually bring sulphur depositions in Europe within the critical loads of receiving ecosystems - is a fundamental principle of ecological sustainability. The emission reduction required was of the order of a factor of ten, as is the estimated order of ...
