The importance of the Santa Cruz Environmental Protection Area is attributed to its biodiversity and primary and secondary productivity, representing an ecological unit of great environmental and socioeconomic significance for the state of Pernambuco. The Santa Cruz Canal Estuarine Complex is recognized as an ecosystem quite vulnerable to pollution and contamination caused by improper land use and occupation. The analysis of heavy metals in soils (Arsenic, Cadmium, Chromium, Copper, Nickel, Lead and Zinc) was used to make situation graphs of the environmental liabilities in which the Santa Cruz APA is located. The results were compared with CONAMA resolution 420/2009 as a guiding model for the reference values of contaminated soil quality. Thus, it was observed that for the arsenic and cadmium elements there were values above the allowed values, suggesting that there is an environmental impact registered in the Santa Cruz EPA probably resulting from agricultural activities and local urban expansion. It can be concluded that there is a need for increased environmental monitoring in both soil sample quantity and environmental parameters, as evidence of environmental disturbances in areas of strategic interest such as APAs has been the result of research. that are in line with the needs of public management.
