The Low Emission Zone(LEZ) was introduced in 2008 to encourage the most polluting heavy diesel vehicles driving in the Capital to become cleaner. The LEZ covers most of Greater London. To drive within it without paying a daily charge these vehicles must meet certain emissions standards that limit the amount of particulate matter(a type of pollution) coming from their exhausts. 3, record 1, English, - low%20emission%20zone

In September 1994, new regulatory amendments under the Canadian Environmental Protection Act came into force to prohibit ocean disposal of radioactive waste and the ocean disposal of industrial waste. In 1995-96, the development of a National Programme of Action for the Protection of the Marine Environment from Land-Based Activities was initiated. It addresses land-base sources of marine pollution and coastal zone management(Environment Canada and Department of Fisheries and Oceans lead respectively). 1, record 2, English, - National%20Programme%20of%20Action%20for%20the%20Protection%20of%20the%20Marine%20Environment%20from%20Land%2Dbased%20Activities

Zones of Water Pollution. Discharge or mixing zone is where pollutants enter the stream or the river. If the waste is dark, it will make the water dark, increase its temperature and subsequently oxygen levels will drop. The rate of discharge should not be stronger than flow of the stream. In zone of degradation oxygen levels drop from BOD(biological/biochemical oxygen demand). Zone of active decomposition is characterized by the following changes : 1) dissolved oxygen(DO) will be at its absolute minimum; 2) odors and gases bubbling up. In the zone of recovery the river will slowly restore its oxygen through aeration process. The anaerobic conditions will disappear. Nitrites will be converted into nitrates and stimulate growth of algae, which will produce oxygen through process of photosynthesis. In zone of clean water oxygen levels are really elevated. And BOD is almost satisfied. 1, record 4, English, - zone%20of%20degradation
