Abstract
Anthropogenic activity in coastal areas cause environmental pollution by heavy metals. One of the heavy metals that polluted sea waters is iron (Fe), which is contributed from fishing boats and tourism activities. Monitoring and assessments of Fe are important to protect of environment. In order to assessment, we need develop method quickly. This study used a microwave optimized Bureau Community of Reference (BCR) method with variations in solvent concentration and pH to attack Fe at fraction 2. The sample used was sediment from the Pasir Putih Situbondo waters at 5 m below sea level. The results showed that increasing the concentration of solvent at fraction 2 reveals the leaching process of Fe more optimally. In the analysis of the level of Fe pollution to the environment around the Pasir Putih Beach did not indicate the potential for Fe pollution due to anthropogenic activity. Most of the Fe sources in the Pasir Putih Beach area were Fe sourced from nature.
