Abstract—This study was conducted to investigate the impacts of red soil contamination in the mangrove area around Matafa’a Mangrove Conservation Area in Samoa. Ten soilsamples were collected from December 2011 – August 2012 on the monthly basis. The pH, Fe, Olsen P and nitrogen (N) contents were determined. Results showed a significant level of Fe content (4.50-41.3 mg/kg), Olsen P (0.03-0.44 mg/L) and nitrogen (0.02-0.29 mg/L), while the pH ranged from 1.40 to 8.90. The results demonstrated that all sites are contaminated with acidic soil which is a common characteristic of red soil contamination which poses a threat to the health of coastal ecosystem including mangroves in Samoa.

Index Terms—Environment, iron, nutrients, toxicity, red soil.
