Lead-210 and Beryllium-7 fallout rates on the southeastern coast of Brazil
Total 210Pb and 7Be fallout rates were measured on the coastal region of Niteroi, Brazil. The monthly depositional flux of 210Pb and 7Be varied by a factor of 26, from 1.7 to 43.3 mBq cm −2 year −1 and ∼27, from 7.5 to 203.5 mBq cm −2 year −1, respectively. The relatively large oscillations in the d...

210Pb and
7Be fallout rates were measured on the coastal region of Niteroi, Brazil. The monthly depositional flux of
210Pb and
7Be varied by a factor of 26, from 1.7 to 43.3 mBq cm
−2 year
−1 and ∼27, from 7.5 to 203.5 mBq cm
−2 year
−1, respectively. The relatively large oscillations in the depositional flux of
210Pb at this study site were likely due to variations in air mass sources, while the
7Be fluctuations may be driven by a combination of weather conditions. Local geology could support the periodic high fluxes of
210Pb from continental air masses, as shifting oceanic wind sources were affirmed by the uncorrelated
210Pb and
7Be fallout activities and
7Be/
210Pb ratios. The
210Pb atmospheric deposition was found to be in agreement with local sediment inventories, an important consideration in geochemical studies that estimate sedimentation processes.
► Fallout rates of
210Pb and
7Be indicate depositional flux during a 12-month period. ► Oscillations in
210Pb and
7Be fallout are driven by geology (
210Pb) and weather. ► Regional trends in
7Be and
210Pb fluxes used in geochemical processes. |
