A laboratory intercomparison of organic carbon (oc) and elemental carbon (ec) measurements of atmospheric particulate matter samples collected on quartz filters was conducted among eight participants of the ace-asia field experiment.
Here, we report the first stage of this intercomparison program, as some laboratories plan to do addi-tional measurements on their own charcoal samples. We intend to extend this program to include other organic remains from chauvet cave (such as bone) and to examine the reliability of dates from.
Currently, a variety of models are available for predicting the uptake, translocation, and elimination of organic contaminants by plants. These models range from simple deterministic risk assessment screening tools to more complex models that consider physical, chemical, and biological processes in a mechanistic manner. This study evaluates the performance of a range of such models and model.
