Figure 4From: Combustion of dried animal dung as biofuel results in the generation of highly redox active fine particulates Time dependent loss of ascorbate associated with incubation of DC at 50 μg/ml at varying concentrations of DTPA. Each trace represents the mean of three separate experiments. The SDs on each mean value are not illustrated for graphical simplicity but were less than 5% of the mean values in all cases.Back to article page
