| Determination of the Level of Sulphur Deposition in Istria by Means of Bioindication pdf HR EN | 487 | |
| SUMARY: Concentration of S02 in the air is elevated near oil refineries and power plants burning coal, as well as in other industrial and urban areas. It has already been proven that the concentration of sulphur in plants is higher when the atmosphere is S0: -polluted. TE Ploniin 2 was put in operation at the end of year 1999. Diferrent to TE Plomin 1, it uses coal with substantially lower percentage of sulphur, which should, in addition to desulphurization, lead to considerably lower emissions of smoke gases. One of the ways to establish deposition of chemical compounds into ecosystems is using certain plant species as bioindicators. In this investigation black pine fPinus nigra Arn.) was chosen as bioindication species for several reasons: black pine stands can be found throughout Istria, it does not shed needles in the autumn, and the needles are kept for several years. The aim of this investigation was to determine the load of sulphur in forest vegetation at various distances to TE Plomin 2. 1- and 2-year-old black pine needles from years J 999 and 2000 were collected and analysed for total sulphur (St) using Leco S-analyser, and subsequently the results were combined for statistical analysis. The results are compared with the tables of critical St values proposed by several authors. Key words: bioindication; critical loads; desulphurization; Pinus nigra; S02 emissions; TE Plomin 2 | ||
