SUMMARY:

Organic pollutants have bioaccumulating effects and cause ecosystem toxicity, aquatic species are highly susceptible to these toxic effects. The objective of this study is to evaluate the bone tissue and estimate osteodensitometric values of eight free-living tortoises (Phrynops geoffroanus), from the Capibaribe river hydrographic basin, which is known to be contaminated by heavy metals and solid waste. Clinical and tomographic evaluation of the tortoises was performed to assess the degree of health for subsequent release. An analysis for bone anatomy revealed that all tortoises had bone changes, among the findings identified bone demineralization, coarse trabecular pattern, subperiosteal bone resorption, dorsal vertebra deformity and hoof fracture. Considering that tortoises are considered biomarkers of water quality, the high incidence of bone alterations suggests an association with environmental pollution in the studied region, this being an alert factor for the conservation of the ecosystem of the Capibaribe basin
