dc.description.abstractABSTRACT: Fogo island (Cape Verde), has an active volcano that last erupted in 2014-15, with melts mainly alkaline, of basanitic to tephritic composition. Dwellings dust composition is the result of natural and anthropogenic interactions. Nineteen house dusts were collected, in representative dwellings all over the island. Fractions < 2 mm was analyzed by ICP-MS, XRF and XRD and SEM for chemical, mineralogical, and morphological characterization. Mineral phases revealed several minerals linked to the volcanic origin. Iron mean concentration in soils, is above the 2014-105 eruption lava mean. Potentially toxic elements were below Acceptable Values (AV), e.g., As 0.6 to 3.3 mg/kg, except once sample 111 mg/kg (AV = 20 mg/kg); Cd, 0,5-3.6 mg/kg (AV = 3 mg/kg). Elements Ni and V presented concentrations above AV in all samples. But is Ti with concentrations much above AV. Risk assessment (USEPA) found As and Ni over the car cinogenic target Risk in most samples, while systemic toxicity in children is mostly due to Fe, V and Zr concentrations. Higher particles concentration is > 50 µm in diameter, suggesting that bioaccessible fraction might not be high, thus, reducing risk.pt_PT
