 abstract={Sulphur dioxide, fluoride compounds and nitrogen oxides are considered to be gaseous pollutants which are most toxic to plants. Depending on concentration and duration of exposure, they can cause visible injuries to leaves (such as chlorosis and necrosis) or hidden injuries. Dusts containing heavy metals are also toxic to plants and can affect animals too, even at minimum concentrations. Air pollution occurs usually as a mixture of dust and phytotoxic gases, composition of which implies the degree of harm done to living organisms. Biological monitoring involves regular application of biological assessment techniques and methods, to gather information about quality and condition of biological systems. In case of two groups of pollutants that are of importance in Poland: heavy metals and sulphur compounds, the method of bioindication using higher plants (alfalfa, ryegrass and two species of clover) may be applied. The method allows assessment of range, dynamics and character of environmental disturbances caused by industrial emissions.},
