SUMMARY:

Organochlorines and nitroaromatics are organic compounds that are relevant in terms of environmental risks due to their toxicity and persistence. These compounds are resistant to chemical or biological oxidation and hydrolysis. The increase in industrialization, population growth, and agricultural activities has contributed to the contamination of the environment by these compounds. Contamination is linked to the disposal of agricultural products, drugs, polymers, and pigment residues. Therefore, finding tools for the treatment of contaminated environments has become increasingly necessary. One of these tools is the use of constructed wetlands, which have the ability to improve the quality of contaminated water through biological, chemical, and physical processes. The first chapter systematically reviewed the literature on the use of constructed wetlands in the bioremediation of organochlorine and nitroaromatic compounds. Articles selected by inclusion and exclusion criteria obtained from the Web of Science and Scopus databases were analyzed. 24 indexed journal articles that evaluated different ways of using wetlands were selected. Information on the construction patterns of the systems (species used, construction material, dimensions, and achieved treatment efficacy) was compiled. The second chapter presents a report of the results of a knowledge co-production with the productive sector. A pilot system of constructed wetlands in a deactivated industrial site with environmental liability of groundwater contamination was monitored for the growth of plant species and contamination of plant tissues. The report aimed to evaluate the vigor of plant populations and the ecological risk of plant use. It was concluded that the plants used established vigorous populations in the treatment systems and that some contaminants, especially anilines/chloroanilines and nitrochlorobenzenes, present considerable ecological risk in real treatment systems and should be evaluated in plant tissues to ensure environmental safety in the application of these systems.
