During the last twenty years, this environmental convention sequence has emerged to be come one of many significant overseas boards at the chemical points of environmental professional tection. The discussion board is termed Chemistry for the security of our surroundings (CPE). The sponsors of this CPE sequence have integrated the Chemical Societies of Poland, France, Bel gium, Italy, Egypt, and the america, the yank Institute of Chemical Engineers, the yankee Society of checking out and fabrics, the foreign Ozone organization, the United countries business improvement association, the Ministries of our environment of Poland, France, Belgium, and Italy, U.S. organisation for foreign improvement, U.S. Environmental safeguard service provider, greater than twenty universities and institutes of upper studying, and 5 nationwide academies of sciences. the 1st assembly during this sequence used to be prepared by means of Prof. Pawlowski and Dr. Lacy in 1976 on the Marie Curie-Sklodowska collage in Lublin, Poland. The convention handled numerous physicochemical methodologies for water and wastewater remedy study tasks that have been together subsidized via U.S. EPA and Poland.

The situation is made even more difficult because, once they are in the environment, chemicals spread in a very complex way and may be converted into other substances which have different effects. Until recently, many hazardous wastes were disposed of without proper evaluation of the environmental consequences such as fires, explosions, air, water and land pollution, contamination of food and drinking water, damage to people and harm to plants and animals. In practice, most of the things that could go wrong have indeed occurred, and in * The editors like to express appreciation to Mr Delmar Blasco, Executive Officer, Environment Liaison Centre, Nairobi, who made this report available for readers of this book.
Fossil fuel combustion yields about 20 million tons of nitrogen a year which have already caused environmental problems on a regional and local basis in industrialised countries. Not all the pollution is acid rain, is sulphuric and nitric acid dissolved in precipitation. Some of it happnes when the sulphur and nitrogen oxides themselves fall out on the land, in what is known as “dry deposition”. In general this tends to be the main form of tHe pollution near its source, and the longer the gases stay in the air, the more likely they are to go through the complex changes that will turn them into acid rain (or wet deposition), to fall perhaps thousands of kilometres from where they began their journey.
Nuclear power stations can be a threat to the environment in the case of an accident, as it is possible to get a leakage of radioactive elements to the environment which could not happen with any other kind of power station. Also, it is possible to pollute the environment during processing of the exhausted nuclear fuel if particular care is not taken, and during storage of radioactive waste. Radioactive isotopes of long life are produced by the nuclear reactions which take place. Radioactive waste can hence be of potential harm to the environment for many generations.
