Description The group of persistent organic pollutants (POPs) contains so called polycyclic aromatic hydrocarbons (PAHs). Due to their physico-chemical and environmentally-chemical properties and resistance to degradation processes, PAHs accummulate both in the abiotic part of the environment and in living organisms. Most of them are potential carcinogenous, mutagenous and teratogenous. Through the vegetation they can reach the food chains. After the uptake by plants, PAHs can (with respect to the exposure period, concentration or transformation stage) cause acute, chronic or latent injury of plants especially in combination with another environmental factors. Metabolic, growth and developmental changes in plants give a proof of an effect to biochemical and physiological processes, driving the growth and development of plants. The main attention is focused to processes which can be used as early indicators of the effect. One of good indicators could be photosynthesis.
