Tourism activities (Marina, Tj. Pinggir)
Domestic activities (Tj. Riau)
Tanker accident & tank cleaning
Reclamation (Sekupang, Tj. Uncang)

3. Objective of Study
To evaluate the environmental status of Coast Batam, Riau Island based on levels of heavy metals in seawater and sediment.

4. Sampling Site

5. Method sampling preparation analyze Sea water sediment
Cd: SNI :2009
Cu: SNI :2009
Pb: SNI :2009
preparation
AAS of Shimadzu AA-7000
analyze

6. Result
Moderate level pollution

7. Conclusion
Cadmium was not detected in seawater from coast Batam, but the level of Cu and Pb in seawater have exceeded environmental quality standard for biota set by Indonesia Ministry of Environment.
Level of heavy metals Cd, Cu and Pb in sediment still meet with quality standard of sediment set by United States EPA, except the level of Cu in sediment from Sekupang was polluted in the moderate level.
