Resumo: 	ABSTRACT It is known the fact that the mining causes huge damages on the environment having negative biologic effects extremely severe on some groups of organisms of the food chain. The pollutants causes major damages at the level of leaves' cuticles, the vegetation reacting through irreversible modifications at the tissue's level and at substances and energy metabolism, like a riposte to the apparition of the stress induced by the ROS, stress that creates real disturbances on physiological and biochemical processes. Considering the fact that, on the one hand, the activity of oxidoreductases is strongly influenced by the presence of the pollutants factors, with direct effect on the oxidative's stress production, and on the other hand that the plants react at ROS accumulation, through self-protection and adaptability mechanisms, the aim of this study consisted in monitoring the activity of some oxidoreductases in the leaves of plantain and mint species harvested in 2015 from different mining areas of Suceava County. In parallel was determined the dehydrogenase activity of the soil, the samples being collected from the same areas subdued to anthropic pollution, using like reference swatch, samples from Putna. The obtained results signalize the accumulation of some quantities highly arisen by free radicals of oxygen at investigated species, the enzymatic activity being significantly higher in the mining plant comparatively to the control areal. The microbial dehydrogenases from the soil samples were remarked through different activities based on the types of heavy metals that pollute each harvesting area and on the deepness profile.
