title: Industrial side-products as possible soil-amendments.
abstract: The protection of our environment is a common task. All pollution that expose our soils, plants or in the narrower and wider sense environment will appear sooner or later in the food chain and in human beings who are at the top of the food-chain pyramid. The aim of our work is to give a brief overview about the effects of some industrial wastes on the physiological parameters of plants. Compost, black soot, sewage sludge and lime sludge dust was examined. Sunflower seeds were used in the experiments. The filtrates of examined materials were added to the nutrient solution in different quantities because of different solubility. The contents of sample elements and uptake of the element were measured by ICP, the relative chlorophyll contents by SPAD 502. Disadvantageous and advantageous physiological effects of compost, black soot, sewage sludge and lime sludge were proved. Larger concentrations of aluminium were measured in the roots than in the shoots. The concentrations of chrome were below the control value in the shoots when black soot, compost, lime sludge and sewage sludge were added to the nutrient solution. The concentrations of zinc, phosphorous, magnesium and copper were very low when black soot was used, and it was lower than the control. The dry matter of shoots increased when compost and sewage sludge was used, but the growth of roots remained under the control level.
