The existence of metals indicates pollution in environment and its toxicity is due to non-degradable substance which tends to accumulate in water, sediment and fish. The presence of heavy metals in water body (i.e. river, stream) is becoming a threat to aquatic animals thereby making them unfit for human consumption. Thus, this study was to investigate the concentration of heavy metal pollution status in sediments of Lapindo Mud, Sidoarjo, East Java in its current condition. Samples were taken from six different locations of Lapindo mud. Heavy metal concentration in mud sediments was analyzed from Lapindo mud in the month of March to June 2015. Physico-chemical analysis was carried out as per standard methods at Laboratory of Soil and Chemistry, University of Brawijaya. The results show that there are eight heavy metals were found. The heavy metal concentration in the sediments is in order B > Fe > Mn > Co > Mo > Cd > Cu > Zn. These results indicated that for the meantime there were no environmental effect of these heavy metals resulted of mud, unless when these metals are associated with other elements. However, the presence of elevated levels of Fe, Mn, and Cd in the sediments is a serious matter of concern and the potential for human exposure to heavy metals. © 2015, Sphinx Knowledge House.
