Comparative analysis of physical-chemical water variable at Rio Itapanhaú estuary – Bertioga – São Paulo – Brazil Deborah Ribolli Ferraz, Roberto Pereira Borges

Abstract

 Even thougth the mangrove importance and the impacts from the anthropic activities in the last decades above those ecosystems are known, there are no management or monitoring policies relationing the biotic and abiotic parameters for them. So, this project aimed analyze comparatively seven water variable in 4 sites at Itapanhaú river, considering de anthropic activities level. It was noticed that all of the studied variables showed significantly differences between the sites, especially the both gradient extremes. However, deeper researches are needed, with temporal comparisons, other chemical characters and other environmental matrixes, to conclusive results.
