Application of factor analysis in geochemical fractions of heavy metals in the surface sediments of the offshore and intertidal areas of Peninsular Malaysia

Application of factor analysis in geochemical fractions of heavy metals in the surface sediments of the offshore and intertidal areas of Peninsular Malaysia

In this study, heavy metal data (including four geochemical fractions) from offshore and intertidal sediments collected off the west coast of Peninsular Malaysia were analyzed using factor analysis. A similarity was found when comparing between offshore and intertidal sediments, where out of the 20...
