The unique set of physical and chemical properties of asbestos has led to its many industrial applications, such as roof coverings, textiles, rope, cord and yarn, paper, friction and composition materials, household product, acid-resistant filters, packing, insulation, and certain types of lagging, amongst others. In Poland asbestos-containing products were manufactured from raw materials imported mainly from the former Soviet Union, with production launched at the beginning of 20th century. According to Annex 4 to the Act of 19 June 1997 on the prohibition of the use of asbestos-containing products, there were 28 asbestos manufacturing plants in Poland located in 11 provinces throughout the country. The current survey was undertaken to enable asbestos manufacturing plants to be arranged, described and divided in order to contribute to further surveys.
Asbestos and asbestos containing products are harmful to human health, and therefore its use has been legally forbidden in the EU. Since there is no adequate data on the amount of asbestos-cement roofing in Poland, the objective of this study was to map asbestos-cement roofing with the use of hyperspectral APEX data (288 bands at the spatial resolution of 2.7 m) in the Karpacz area (southwest Poland). A field survey constituted the basis for training and verification polygons in the classification process. A SAM classification method was performed with the following classification results: 62% producer’s accuracy, 73% user’s accuracy and an overall accuracy of 95%. The asbestos-cement roofing for buildings may be discriminated with a high classification accuracy with the use of hyperspectral imagery. The vast majority of the classified buildings were characterised by their small area (i.e. residential type buildings), which reduced the overall accuracy of the classification.
Because of its harmfulness to human health, asbestos has been banned in 55 countries, including the EU. In Poland, the use and production of asbestos and asbestos-containing products has been forbidden since 1997. However, there is no precise data about the amount of asbestoscontaining products to be eliminated from the territory of Poland. This survey aims to identify characteristics that have a significant impact on the estimation of asbestos-containing products used in Poland. Statistical correlation between the results of the physical inventory count done in 155 municipalities was examined. As a result of the survey it was found that the amount of asbestos-cement roofing depends on the following factors: the number of individual farms in the village, the distance from the asbestos manufacturing plants, the age of the buildings and the economic situation of municipality. The results obtained may contribute to the ability to predict the amount of asbestos-containing products used in other municipalities.
On January 1, 2005 the use of asbestos-containing products was banned in the European Union. According to the Act of 19 June 1997 banning the use of these products, their usage in Poland should be abated by the end of 2032. The whole process is being monitored by the Electronic Spatial Information System for the Monitoring of Asbestos Products Removal. The system design was based on a geodatabase. The research area of the study is the whole territory of Poland at the national, provincial and local level of detail. The monitoring process embraces spatial analysis through the preparation and interpretation of a range of maps. The results obtained from the deployed methods proved that the system has been useful for decision making purposes during the monitoring process. The proposed solutions were appreciated by the EU.
Celem artykułu jest identyfikacja zmian w międzynarodowym handlu azbestem na podstawie analizy eksportu i importu w latach 2002-2018. Źródłem danych statystycznych dla badanego okresu była baza danych handlowych TrendEconomy. Uzyskane wyniki pokazują, że w latach 2002-2018 światowy eksport i import azbestu wzrósł odpowiednio o 203,88% i 130,91%. Kraje transformujące się w głównej mierze zaspokajały światowy popyt na azbest, w tym Rosja, której udział w 2002 r. stanowił 62,0%, natomiast w 2018 r. 60,8%. Import azbestu przez kraje rozwinięte cechował się wyraźną tendencją zniżkową. W 2002 r. głównymi importerami okazały się kraje rozwijające się: Tajlandia i Chiny. W 2018 r. takimi krajami były Indie i Indonezja.

The purpose of the article is to identify changes in international trade of asbestos. The article analyses the export and import in the period 2002-2018. The source of statistical data for the analysed period was the TrendEconomy commercial database. The results show that in the years 2002-2018 the worlds export and import of asbestos increased by 203,88% and 130,91%. The transformation countries mainly exports of asbestos, including Russia, whose share in 2002 to 62,0%, while in 2018 60,8%. Import of asbestos by developed countries showed a downward trend. In 2002, the main importers were developing countries: Thailand and China. In 2018, such countries were India and Indonesia.
