Speciation, reactivity and mobility of toxic elements in soil systems,chanisms, as a result of the type of surface-chemical interaction, on the mobility of toxic chemicals. Specific oxyanion adsorption, metal adsorption and anion exclusion are highlighted. The effects of different physico-chemical parameters on the mobility of arsenic, mercury and nitrate are emphasized.

Spatial distribution and seasonal patterns of aquatic emergent plants in Southeast Brazil: Developmths over 0.2 m depth. Productivity values (2,022 and 2,227 g m. y.) are in the world-wide range for the genus. A classification of the . swamps in different areas according to flooding exposure is proposed.

Hydrogeochemical description of groundwaters from a coastal region of Rio de Janeiro state, Brazil,us: sulphate, ammonia, nitrate and phosphate. Evidence of contamination by domestic sewage and salinization of waters were shown to occur in a localized manner. The occurrence of reduced iron in well waters was generalized. Indices of vulnera-bility of the aquifers of various sub-areas are presented.

Soil-to-plant transfer of 137Cs related to its geochemical partitioning in Oxisols of tropical areaasic oxisol with normal exchangeable K contents presented lower Tf values: 0.06 to 0.11. These values were higher than mean values reported by IUR for .Cs for beans under temperate climate: 0.03. Results of sequential extraction showed .Cs weakly bound to soil components and underline the importance of Fe oxides in the control of .Cs availability.
