BIOINDICATION WITH GARDENPLANTS, A METHOD TO CONTROL AIR-POLLUTION IN INDUSTRIAL WORKS

Pollution control in industrial works is usually carried out by means of analytical measuring methods at the pollution sources. Additional investigations by means of bioindication carried out during 19 years have brought forward many important information which could not have been gained with analyses only. The advantage of bioindication is that plants record pollutants continuously. Using this method it was possible to find even minute and unexpected pollution sources. Damage symptoms and growth rates of plants can be easily determined and recorded, even by non professionals. The described method has been successfully used for years. The arising difficulties are also emphasized.
