Brazilian harbours are expanding rapidly during the past years. In order to develop strategies to mitigate environmenmtal risks resulting from this economic development it is imparative to identify the potential sources and pathways of pollution. Especially open cargo handling of soy bean products results in an increasing input of organic matter to the marine environment. Another site-specific source of pollution with organic and inorganic nutrients is the fertilizer throughput inside the harbour.

In addition, a considerable amount of untreated sewage water deriving from the harbour and city of Paranaguá is discharged into the bay. Only 20 % of the municipal sewage water is subject to wastewater treatment. The input of untreated sewage water constitutes an hygenic risk and several cholera outbreaks have been reported from the area. For this reason bacterial investigations, too, were part of the investigations.
