The concentration of lead heavy metal (Pb) in the sediment of Tantui coastal area, Hative Kecil Village, Outer Ambon Bay

Abstract

The pollution of lead-heavy metal (Pb) not only harmfully towards aquatic organisms, but also to a human directly or indirectly. The objectives of this study were to analyze the concentration of lead-heavy metal (Pb) accumulated in the sediment, to identify human activities potentially increase the lead-heavy metal in the sediment, and to recommend management strategy to minimize lead heavy metal concentration in the sediment surround Tantui coastal area, Outer Ambon Bay. The research was conducted in January 2020. Data on lead heavy metal were sampled purposively from 5 sites along the coastline of Tantui. Samples obtained were then analyzed using Atomic Absorption Spectrophotometry (AAS). Data on human activities were obtained through field observation and interviews using a close questionnaire against respondents taken randomly. Problem tree analysis was used to analyze human activities and produce management strategies. The result shows that lead heavy metal concentration at 5 sampling station range between 0.0975 - 0.1631 ppm. This concentration was not over the standard value allowed. Source of lead-heavy metal identified were marine transportation and domestic waste. Management strategy consent recommended are monitoring on marine transportation, provide littering and sanitation facilities permanently, and beach clean-up as a routine agenda.
