ABSTRACT: The construction of vertical gardens and the study involving species of insects and plants biomonitoring technique a relatively new topic in the environmental sciences. Thus, the objective of this article was to carry out active biomonitoring of air quality using plant and insect species in a vertical suspended garden system. For this, five bioindicator plants were used: T. pallida, T. zebrina, J. brandejeana, L. Câmara, and R. nasturtium aquaticum. Growth measures were taken; quantification and characterization of stomata; determination of visiting insect orders and determination of heavy metal concentrations. The results indicated that the stomata of the bioindicator plant species R. nasturtium aquaticum presented stomata in both epidermises, but preferably in greater numbers on the adaxial surface regardless of the place of cultivation, differently from other species, which due to the species itself or due to plasticity, presented higher amounts of stomata on the abaxial surface, justifying protection for the gas capture system of atmospheric pollutants so that photosynthetic rates can occur normally. It is possible to conclude that the plants used in this study showed adaptations and are bioindication sources of environmental pollution. As for the visiting insects, the orders identified showed variations in the concentrations of heavy metals, however, specific Brazilian pollution indexes in invertebrates do not yet exist, therefore, in this research, comparisons were made with other studies related to the country.
KEYWORDS: Ecological Indicators, Air Pollutants, Heavy Metals.
