Assessment of the anthropogenic influence on contamination level present in Vitória's bay - Espírito Santo, Brazil

Abstract

This work propose research evaluation of the estuarine system in Vitória's port, Espírito Santo - Brazil, which is located on Vitória's bay, within the estuarine system comprising rivers Santa Maria da Vitória, Bubu, Itanguá and Aribiri, which are of economic importance for the local riverside community. The research proposed the evaluation of water quality and sediment used for physical, chemical, microbiological and bioassay analyses, thought evaluation anthropogenic impact derived of port implementation and expansion port process. The monitoring network created consisted of 21 sampling stations numbered from BVP1 to BVP7 and from BVC1 to BVC14. Among the Physico-chemical parameters to be assessed are pH, flow, depth of the vessel transition system, turbidity and salinity. Additionally, highly carcinogenic metals (arsenic, chromium, nickel, copper, lead and zinc), organic parameters and zoobenthos level research in port square thus quantification were important quantified through ecotoxicological tests, chemical analyses, and other organic parameters studies, however quantification total organic carbon (TOC), precipitated carbonate, total nitrogen, total phosphorus, redox potential and flow capacity, which were assessed to better understand the cause of their accumulation and to assess and purification capacitation at estuarine system.
