Monitoring the Quality of Water, Air and Noise

Date started: 2004 

We carry out environmental monitoring contemplating the quality of water resources and atmospheric areas of Porto and Mines, according to environmental constraints. The main objective is to mitigate the possible interference of the activities developed by the company on the at

Currently, the network monitoring water quality has sampling points distributed throughout the enterprise.

In this work, and monitoring of physico-chemical and microbiological do the limnological and fish fauna (fish). The water monitoring also includes the study of density, species richness and diversity of fitoplantons (algae, etc.) and zooplankton (microscopic animals). These analyzes can be used as indicators of the quality of water as small organisms existing therein indicate changes in the middle. The ichthyofauna and limnological monitoring is done in partnership with the Federal University of Rio de Janeiro (UFRJ).

Since the atmospheric monitoring program is divided into monitoring air quality and environmental noise. The first is monitored weekly for 09 stations that analyze the concentration of suspended particles (TSP) and inhalable particles (IP). Noise, in turn, evaluates the environmental sound pressure generated by the equipment in operation in the mines during the daytime and nighttime periods. The noise data generated are obtained by monitoring points.

As part of the atmospheric monitoring, MRN monitors air emissions generated by drying the ore and power plant, as well as greenhouse gas emissions from automobiles and industrial diesel.

The work of monitoring surveys are made with field data and laboratory tests, and all parameters compared with the standards established by specific legislation.

Therefore, all activities in Porto Trombetas, whether commercial, residential or industrial action which could result in environmental impacts are monitored.​
