摘要

Tukad Mati is one of the ten rivers has decreased due to the development of water quality screen printing and textile industries. Monitoring of the waters of the Tukad Mati has so far been confined to the Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) only. Whereas monitoring should be carried out thoroughly considering the heavy metal content is also harmful to users of water resources in Tukad Mati. One of the natural buffer of heavy metals in sediments of mangrove waters is a final media gathering all kinds of heavy metals waters, while mangrove itself is a natural sediment trap.Therefore, the heavy metals in the waters will experience the highest accumulation in mangrove sediments. The purpose of this study is as early monitoring to detect the chromium metal in waters and sediments in Tukad Mati estuary. In this study conducted in on-site data measurements in the form of data pH, temperature, salinity, disolved oxygen (DO) and discharge water. measurement of chromium content in the water and sediment of Tukad Mati estuary using AAS method.The study showed that from the results of on-site data measurements in estuary of Tukad Mati showed that the average value of salinity, pH, temperature and Dissolved Oxygen still meet quality ministerial decree of the environment of Indonesian Republic no 51 in 2004 for biota and marine tourism. The measurement results also showed that chromium content in water an average of 0.19 (mg/l) and exceed the ministerial decree of the environment of Indonesian Republic no 51 in 2004. Mangrove and non-mangrove sediments in Tukad Mati estuary have been exceed the Lowest Effect Level for organism and some sediment contaminated with chromium and passed the quality standards According to Canadian Council of Ministers of Environmental in 2000. Chromium concentration in sediment higer than water allegedly caused by heavy metals that tends to bind and fall to the bottom waters along the process of sedimentation.
