From page 216... ... Sulfur as a macronutrient has an optimum concentration, and deficiencies or excesses can be deleterious for plant growth. Extensive studies conducted by the PAN Botanical Garden have identified the normal, physiological requirement of sulfur for pine needles (fin us Read the entire page →
From page 217... ... A comparison is made of four distinct zones of air pollution in Poland and approximate SO2 content in air in micrograms per cubic meter. These data indicate a relationship between the expected and experimentally determined level of toxic effects and the sulfur content in pine needles. Read the entire page →
From page 218... ... The distribution of different zones of pollution presented in terms of sulfur content in pine needles is shown in Figure 3a. Only a small part of Poland has air relatively low in sulfur. Read the entire page →

From page 225... ... The normal lead content of plants ranges from 2 to 10 ppm; concentrations of 30 to 300 ppm is considered toxic (Kabata-Pendias and Piotrowska, 1984~. In Poland, lead content in pine needles is very low, with a background level below 10 ppm. Read the entire page →
From page 226... ... consider zinc content in plants to be toxic between lOO and 400 ppm, with normal levels ranging from 20 to lOO ppm in uncontaminated areas. In this study, the background concentration of zinc found in pine needles was below 70 ppm. Read the entire page →
From page 227... ... CONCLUSION Chemical analysis of pine needles and pollutant content transported by air allow the production of maps which document air pollution impact on vegetation. These maps can be produced on differentlevels: for a large region, e.g., Poland (312,000 km2) Read the entire page →
From page 228... ... Zinc content is rather low; only in the area of an old zinc industry does the content of zinc in pine needles exceed 100 ppm. The results presented in this chapter provide a basis for further research in the area of air pollution impacts on vegetation. Read the entire page →
