The distribution of heavy metals in earthworms has been widely studied, highlighting the importance of the fate of these metals. However, little information is available on the distribution of hydrophobic organic contaminants (HOCs) within earthworms. The aim of this study was to propose a hierarchic method to study the distribution of phenanthrene (PHE), a typical HOC, in Eisenia fetida at several...
Acid sulfate soils are normally not suitable for crop production unless they are appropriately ameliorated. An experiment was conducted in a glasshouse to enhance the growth of rice, variety MR219, planted on an acid sulfate soil using various soil amendments. The soil was collected from Semerak, Kelantan, Malaysia. Ground magnesium limestone (GML), bio-fertilizer, and basalt (each 4 t ha −1 ...
Enzyme activities have the potential to indicate biological functioning of soils. In this study, soil urease, dehydrogenase, acid phosphatase and invertase activities and fluorescein diacetate (FDA) hydrolysis were measured in two red soils spiked with Pb 2+ ranging from 0 to 2 400 mg kg −1 to relate the enzyme activity values to both plant growth and the levels of available and total...
