Analisis Kandungan Pencemar Logam Berat (Pb Dan Zn) Pada Air, Sedimen Dan Siput Hisap (Cerithidea Obtusa) Di Desa Tanjung Pasir Kecamatan Tanah Merah Kabupaten Indragiri Hilir Provinsi Riau
The Nyiur and Enok Rivers merged and form a single river mouth in the Tanjung Pasir Village. Around the river mouth, however, many industrial and shipping activities may produce Pb and Zn pollutant that enter the water, accumulated in the sediment as well as in the meat of benthic organisms such as Cerithidea obtusa. To understand the concentration of Pb and Zn in the water, sediment and the snail, a research has been conducted on March 2017. There are 3 stations, around 3 km before the outlet of PT Sambu, in the outlet of PT Sambu and 3 km of PT Sambu. Samplings were conducted 3 times, once/ 2 days. Results shown that the highest concentration of Pb and Zn in water (0.0543 ppm and 0.1767 ppm), sediment (1.7469 ppm and 3.2720 ppm) and C. obtusa (4.9085 ppm and 8.1990 ppm) was in the station II.
