Title : Lumbricus terrestris Linnaeus 1758 and Pheretrima sp as a Bioremidiator in Cooper and Cadmium Polluted Soil

Abstract :

The aim of this study was to determine the BCF and the TF value of heavy metals in Oligochaeta. This study obtained data on heavy metal Cu and Cd pollution that affect soil quality and the potential of Oligochaeta L. terrestris and Pheretrima sp as bioremidiator for Cu and Cd in Jatibarang Landfill. The research method used is field experiment. Samples were then prepared for heavy metal analysis using the ICP MS. The BCF and TF value were calculated using formulas; the BCF value was calculated as the content of heavy metals in oligochaeta divided by the concentration of heavy metals in soil. This study measures and analyzes the concentration of two types of heavy metals, Cooper (Cu) and Cadmium (Cd) from 2 Oligochaeta species in Jatibarang Landfill Semarang Indonesia. The BCF value is the concentration ratio of heavy metals concentration in the organs of the esophagus or the dermis with heavy metals concentration in the soil) and the TF value is the ratio of heavy metals concentration in the dermis and esophagus) Cu on Lumbricus terrestris (3.596 ppm) is higher than Pheretrima sp (1,333 ppm), as well as Cd concentration in L. terestris (0.239 ppm) is higher than Pheretrima sp (0.079 ppm). Based on this research, the BCF and TF value for heavy metals in L. terrestris and Pheretrima sp were > 1 that means that those species are bioaccumulators. The results of the analysis of Cd in soil show the concentration of Cd in soil at site 5 exceeds the limit of the concentration of available metals. The TF values for Cu and Cd the dermis of Pheretrima sp were 0.663-2.072 and 0.185-1.668, and in the esophagus were 0-45.824 and 0-13.5 respectively. The TF values for Cu and Cd in the dermis of L. terestris were 0.103-12.568 and 0-0.598, and in the esophagus 0.355-16.758 and 0-1.307 respectively. The heavy metals from soil were absorbed, transported and accumulate in dermis and esophagus, therefore, L. terestris and Pheretrima sp are good bioremediator particularly Cu and Cd that can be apllied to remediate soil contamination with heavy metals
