Green teams are frequently considered in the state-of-the-art literature as an essential factor for companies aiming to implement and improve environmental management approaches and practices. However, most of the available literature on green teams is conceptual and theoretical by nature. Therefore, the main purpose of this article is to evaluate the main characteristics of green teams in Brazilian companies and to analyse the relationships between green teams and the maturity level of environmental management in those companies. Based on a conceptual background on corporate environmental management and green teams, a research was done in two complementary phases: a survey of 94 companies with ISO 14001 certification; and a multiple case study of four industrial companies. Survey results suggest that 82% of the studied companies have cross-functional green teams, i.e. involving various companies' departments; and 65% have functional green teams, i.e. individual department teams. The results of the case study suggest that the use of green teams is an instrument to the greening of companies with ISO 14001 in Brazil. The company with the most proactive and advanced environmental management is the same company which uses green teams more intensely. Green teams are especially necessary for implementing more technical environmental management practices, e.g. Life Cycle Assessment. Since this is one of the first studies analysing green teams, the results presented can be useful for companies and public policies aiming to implementation of environmental initiatives. © 2012 Elsevier Ltd.

Water pollution found in major rivers in Brazil has its origin from urban sewage discharges and industrial effluent, carried out by small streams and rivers crossing cities. Therefore, studies related to hydrographic micro-basins offer the opportunity to establish environmental management strategies for restoring water resources, based on diagnosis of the water quality. Despite this understanding, few studies in urban and rural areas have been performed in a systematic manner in Brazilian micro-basins. The main goal of this research was to diagnose the water resources in micro-basins in the region of the district of Americana, São Paulo state, Brazil, through the quantification of metals in water and sediment. The methodology was based on the investigation of metals (Ba, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn), in four micro-basins, determined by inductively coupled plasma optical emission spectrometry (ICP-OES). The most significant result showed high concentration levels of chromium (969 μg L-1), downstream of the discharge of sewage from the city of Nova Odessa. This concentration in the river was above the allowed limit of Brazilian regulation agency (50 μg L-1 for Cr). Also high levels of Cr were found in the sediment (98.9 μg g-1) collected at the same monitored site. These results are important indicators of environmental performance and anthropogenic activities to help the government establish environmental management strategies aimed at the reduction of water pollution. © 2013 WIT Press.

Santos-São Vicente Estuarine System is a highly populated coastal zone in Brazil and where it is located the major port of Latin America. Historically, port activities, industrial and domestic effluents discharges have constituted the main sources of contaminants to estuarine system. This study aimed to assess the recent status of sediment quality from 5 zones of Port of Santos by applying a lines-of-evidence approach through integrating results of: (1) acute toxicity of whole sediment and chronic toxicity of liquid phases; (2) grain size, organic matter, organic carbon, nitrogen, phosphorus, trace metals, polycyclic aromatic hydrocarbons, linear alkylbenzenes and butyltins; (3) benthic community descriptors. Results revealed a gradient of increasing contamination for metals and organic compounds, alongside with their geochemical carriers. Sediment liquid phases were more toxic compared to whole sediment. Low number of species and individuals indicated the impoverishment of benthic community. The use of site-specific sediment quality guidelines was more appropriate to predict sediment toxicity. The integration of results through Sediment Quality Triad approach and principal component analysis allowed observing the effects of natural stressors and dredging on sediment quality and benthic distribution. Even with recent governmental efforts to control, pollution is still relevant in Port of Santos and a threat to local ecosystems. © 2013 Elsevier Ltd.
