Resumo
The objective of the present work is to determine 210Po activity concentration in estuarine sediments from
Baixada Santista. The area comprehends nine cities in the Brazilian coast (Bertioga, Guarujá, Santos, São
Vicente, Cubatão, Praia Grande, Mongaguá, Itanhaém and Peruíbe). It is one of the most important industrial
areas in Brazil due to the large number of industries operating in Cubatão, such as steel, petrochemical and
fertilizer industries. That, together with a large population, causes a negative impact on marine biota. The cores
were obtained from São Vicente and Bertioga by extracting profiles up to 1 meter depth with a Piston core
sampler. The samples were prepared and treated with both physical and chemical processes. The physical
processes include drying, grinding and sieving. The chemical preparation consists of a series of acid digestion
till total dissolution and destruction of organic matter. After the acid digestion, the samples were filtered and
evaporated till dryness. The residue was then dissolved in HCl 6.25 M. Po was spontaneously deposited in
mirror finished silver disc, for 2 hours at 90 °C and constant agitation. The disc was then counted in a surface
barrier alpha detector for 200,000 seconds. Three cores were analyzed so far, two from São Vicente and one
from Bertioga.
