AbstractAbstract
[en] Seawater samples were collected from the Atlantic Ocean, in the vicinity of Ubatuba (Sao Paulo State - Brazil), acidified to pH 1 and stored in polyethylene containers. Cesium was precipitated with ammonium phospho molybdate (AMP), synthesized in our laboratory. The elements potassium and rubidium present in the seawater are also coprecipitated by AMP and adequate decontamination of the cesium is made by preparing a column by mixing Cs-137 AMP precipitate and asbestos. The interfering elements were eluted with 1.0 M ammonium nitrate solution whereas cesium was eluted with 1.0 M sodium hydroxide solution. Cesium was reprecipitated by acidifying the solution with concentrated hydrochloric acid. The overall chemical yield of cesium was of 75%. (author)

AbstractAbstract
[en] Fine and coarse particles in suspension in the atmosphere were collected on two teflon filters using a dichotomous sampler. The concentration of Al, Br, Ca, Ce, Cl, Co, Cr, Fe, K, La, Mn, Na, P, Pb, S, Sb, Sc, Se, Si, Sm, Th, V, and Zn was determined by ED-XRF and INAA. The elemental concentration was analyzed using linear correlation coefficients, enrichment factors and principal factor analysis, in order to identify the aerosol sources. The main sources of the aerosol particles were the marine one, re-suspended soil, fuel oil combustion, phosphatic rocks, refuse incineration and residual high temperature processes.
