Kandungan Logam Berat Pb Pada Organ Ikan Gabus (Channa Striata) Dan Ikan Barau (Hampala Macrolepidota) Di Waduk Plta Koto Panjang Kabupaten Kampar Riau
Abstract Snakehead fish (Channa striata) and barau fish (Hampala macrolepidota) are commonly found in the Koto Panjang Dam. As heavy metal containing pollutans such as domestic and plantation wastes enter the water, the remains of the heavy metals may be accumulate in tissue of fish living in that area. A study aimed to determine the content of Pb in the gills, kidneys, and muscle of those fishes was done from May 2020- January 2021. Samplings were conducted twice, once/2 months. The tissues were removed and analyzed for heavy metal content. The gill was processed for histological study (alcohol series, paraffin embedded, and Hematoxylin Eosin stained). The heavy metal was analyzed using an AAS method. Results showed that Pb content in the snakehead fish tissue was 0.1118-0.1349 mg/kg (gill), 0.0618 0.1163 mg/kg (kidney), and 0.0644-0. 1170 mg/kg (muscle). In the barau fish organ the Pb content was slightly lower, which was 0.0540-0.0786 mg/kg (gill), 0.0687-0.0840 mg/kg (kidney), and 0.0687-0.0881 mg/kg (muscle). Based on data obtained it can be concluded that the heavy metal content in the organs of both fish species was relatively low and those fishes might be consumed safely. Histological study showed that there was light abnormality such as hyperplasia and hypertrophy in the gills of both fishes. Results of Pb content and gill histological structure study indicate that the snakehead and barau fish from the Koto Panjang Dam was healthy.
