Kandungan Logam Berat Pb Dan Cd Pada Muatan Padatan Tersuspensi Di Perairan Sungai Sail Kota Pekanbaru
Many anthropogenic activities are conducted along the watershed of the Sail River
and thus producing pollutant that may enter the water. As the pollutant may contain
heavy metals, the metal trace might be found in the water’s suspended solid. A
research aims to understand the Pb and Cd content in the suspended solid from the
river has been conducted in February-March 2019. Sampling were conducted 3
times, once/ 10 days and samples were taken from 3 stations, namely upstream
(Station I), middle part (Station II) and downstream (Station III). Results shown that
the average of suspended solid in the upstream was 149 mg/L), in the middle part
was 237 mg/L and in the downstream was 114 mg/L. The average of Pb and Cd
content in the suspended solids from the upstream was 0.00046 mg/L and 0.0364
mg/L respectively, from the middle part was 0.0030 mg/L and 0.0303 mg/L. While
the average of Pb and Cd content in the TSS from the downstream was 0.0024 mg/L
and 0.0248 mg/L respectively. Based on data obtained, it can be concluded that
the Sail River waters has been contaminated by Pb and Cd.
