Research
Interest
The mobility, “bioavailability”,
of trace hazardous metals(loids) such as cadmium, a soil contaminant,
is largely controlled by adsorption reactions at the mineral/water
interface, forming surface complexes and precipitates. Bioavailability
is a dynamic property mainly influenced by temperature, pH, redox
potential ability, mineralogy, organic matter composition, bacterial
activity, and climatic conditions.
To understand the relationship
between cadmium bioavailability in soil and cadmium accumulation
in plants we have to know the chemical mechanisms of cadmium in soils.
This knowledge will advance an understanding of the benefits for
both preventing and solving the problems of cadmium contamination in
soils and plants.
My research is focused on the problems of cadmium
contamination in tropical soils, and uptake in rice grown in Thailand
and other areas of Asia.
I am interested in studying the various
conditions and environments that affect mobility of cadmium in
soils and plants, concentrating on kinetics, adsorption, and
desorption. In
addition, my research shall address the influence of soil microorganisms
on cadmium speciation in soils. The final goal is to obtain
a kinetic model of cadmium sorption/desorption processes in
soils, and to identify cadmium speciation and distribution
in soils and plant tissues.
