Kontaminasi Logam Berat (Pb, Cd, Cu, Zn) Pada Air Dan Sedimen Sebagai Indikator Pencemaran Di Perairan Selat Lalang, Kabupaten Siak
This research was conducted from November 2019 to March 2020 which took
place at the Chevron Duri Laboratory and Marine Chemistry Laboratory, Department of
Marine Sciences, Faculty of Fisheries and Marine, Riau University. The purpose of this
study was to analyze the concentration of heavy metals (Pb, Cd, Cu, Zn) and to determine
the relationship between heavy metal concentrations in water and sediments in the coastal
ecosystem of the Selat Lalang of Siak District. This research method uses a survey
method, the Selat Lalang as a location for observation and sampling for analysis and
discussion descriptively. The results of the analysis of heavy metal concentrations in
water with Pb values 0.0091 - 0.0097 mg / l, Cu 0.0093 - 0.0098mg / l, Cd 0.0090 -
7.6500mg / l and Zn 0.100 - 0, 2700mg / l. Meanwhile, the analysis results of heavy metal
concentrations in water with Pb values 11.18 - 17.02 (μg / g), Cu 2.20 - 3.83 (μg / g), Cd
0.39 - 0.99 (μg / g ) and Zn 49.64 - 70.38 (μg / g).
Key words: Heavy Metal Contamination, Pollution Indikator, Selat Lalang
