Determination of heavy toxic metals in the environment indicator specimens (water, river sediment and kangkung plant) of Muria terrestrial

Analysis and evaluation contain of heavy toxic metals in the water kangkung plant (Ipomea reptans poir) and river sediment of five rivers sampling location at peninsula Muria region by NAA Instrumental method has been done. The method of sampling. preparation although analysis method according to standard procedure of environmental specimens analysis. Accordingly the quality standard of water group C although group D. the sample from fifth river location sampling was under allowed maximum Cd concentration. Correlation between variable location and kind of indicators to heavy metal concentration was shown by coefficient of Pearson correlation. Interpretation by statistic correlation was obtained. Correlation between kind indicators was indicated that river water has significant correlation with the kangkung plant about Cd concentration. (author)
