ResumoCurrently, the increase in the environmental radioactivity levels was due to anthropic activities, such as the oil industries that produce around 2.5x104 to 2.25x105 tons of contaminated materials per year. Thus, the study aimed to determine the 210Pb concentrations in the estuarine region of the SUAPE industrial complex in the state of Pernambuco. The 210Pb concentrations were determined in soil, sediment, fish, and leaf samples, using ion exchange and gamma spectrometry methods. 210Pb concentrations in soils, sediments, fish, and mangrove leaves ranged from less than LD (Detection Limit) to 992.35 Bq.kg-1. The results showed that the area related to the preoperational situation found values above those estimated for regions considered natural, presenting anthropogenic interference.
