Assessment of Total Hydrocarbon Soil Content of <i>Rhizophora mangle</i> and <i>Nypa fruticans</i> at Onne and Eagle Island

The assessment of total hydrocarbon soil (THC) content Rhizophora mangle and Nypa fruticans was investigated. Plant part the studied plants (leaves, root, stem) were collected from forest. In each study area a 20 x 20m plot delineated. Within 10 trees sampled randomly using stratified systematic analyzed sampling method. For analysis, fresh samples insitu with augur weighed placed in sterile polythene bags sent to laboratory, location 3 replicates used for both locations. leaves, pieces root stem red mangrove harvested similar techniques adopted Nypa palm cooler taken laboratory analysis. THC plant parts, physicochemical parameters water. result generated showed significant variation accumulation more than roots. leaves bark Mangle accumulated high concentration THC. This that higher productivity litter fall is mechanism counter effect pollution polluted rain forest environment. could be referred also as hyper accumulator due its ability accumulating amount leaves.
