Effects of heavy metals salts on the prollin synthesis in Lemna minor L

Assessment of the level of water pollution is an important component of pollution monitoring. Rivers are polluted by sewage from enterprises and it is often difficult to assess the level of pollution and toxicity of the surface waters. Usually chemical methods of research are time-consuming and expensive. Methods of biotesting and bioindication can give a quick and accurate answer about the toxicity of waters. Nowadays, integrated methods are needed to assess the level of water pollution and water toxicity, especially in regions with a well-developed industry, where there are rivers that experience anthropogenic pollution. In many researches special attention is given to the study of low-molecular antioxidants as biochemical indicators of environmental pollution as well as biomarkers of the physiological condition of the plants growing under stressful environmental conditions. Lemna minor is an interesting plant which is available as a bioassay. It is widely spread, can be easily cultivated and is sensitive to contamination by heavy metals...
