Abstract
The work examined sediments from the adjacent area to the Pium estuary (Pirangi Beach), in the municipality Parnamirim - RN. The main objective of the study was to assess the degree of pollution of the regions, bases upon foraminiferal associations and their responses to abiotic factors (temperature, depth, salinity, and sediment characteristics including grain size, % calcium carbonate and % organic matter). Abiotic parameters were measured and 12 sediment samples were collected from the coastal zone, adjacent to Pirangi Beach. Areas closer to Pium estuary were more affected by anthropogenic. The dominant species in this area is Quinqueloculina lamarckiana.
Keywords: Foraminifera, environmrntal indicators, abiotic data, sedimentology
