Mangrove soils have unique properties, able to transform and sequester chemical compounds of biogeochemical and ecological importance, including heavy metals. The degeneration of mangrove soils shows the risk of releasing these metals to the environment. We search for improve the knowledge about how disturbance affects the metal fixation and microbial of mangrove soils. This study characterized a mangrove soil along the Graciosa River estuary (Bahia, Brazil), according to selected physical, chemical and microbiological properties. In 2002, soil was collected from an anthropic and from an adjacent natural site. Both sites were re-sampled in 2007, after a vegetal regeneration on the anthropic site. Significant differences between the natural and anthropic surface layers were observed for chemical and physical soil properties. In particular, heavy metals (Co, Cr, Cu, Zn, Ni, Mn and Fe) showed significant differences with depth and lower concentrations were found in the anthropic site, exception to Cd (moderately high). Between 2002 and 2007, the disturbed site showed a decrease for all observed metals, except for Ni. The data also suggest that microbial populations may be favored in the layers of the soil profile most influenced by high and low tides, C1 (0-20 cm) and C5 (99-125 cm). |

The monitoring of pesticide residues in rice grain is a mandatory requirement under the Integrated Rice Production (PIA), the official instrument of the Brazilian Government for certification of this cereal. This study aimed to determine the concentration of pesticides in grain, husk and rice bran produced in three PIA areas in the states of Rio Grande do Sul and Tocantins. |
