No cost-benefit study has been made in the sulphur industry. Therefore the real costs of mining of this raw material together with the social costs which include the ecological ones are not known. Meanwhile the latter costs are very high and they include, among others, the degradation of soils under the dumping grounds, pollution of surface and underground waters, air pollution, degradation of natural...
In Poland voices of admiration are often raised because of the excellent legal regulations which control the environmental protection.

The air pollution changes the species composition of plants, decreases the growth of the stand of trees, abates their health and increases the appearance of the secondary...
The results of investigation on the chemical composition of precipitations in the years 1984— 1986 and in 1987 are presented. A clear variability of the macroelement concentrations has been observed — they were twice as high during summertime as during winter. Hydrogencarbonate, sulfate and chloride ions constituted a high fraction of them. Excessive concentrations of sulphur have the most negative...
The common view in the world is that the costs of nuclear power plants cannot be foreseen on account of their constant growth and a tendency to underrate the value of the cost estimation. This is even more so in the case of the first Polish nuclear reactor constructed at Żarnowiec the costs of which have been officially estimated at 110 mld zł. According to the author's view, in Poland which has a...
In the field of environmental protection new forms of international financial co-operation have appeared, such as: proecological credits granted by the World Bank, especially to the developing countries, and operations within the framework of the so called debt trade with the participation of international ecological organizations.
