Description:
Eight species of plants were exposed to nitrobenzene in a hydroponic solution. our species experienced no depression of either transpiration or photosynthetic rates, while one was rapidly killed and the other three were temporarily affected but recovered from the treatment. ptake of nitrobenzene was passive and was shown to be proportional to the rate of water flux in each species. he transpiration stream concentration factor (TSCF) was 0.72. he root concentration factor (RCF) was variable between the species and was higher than expected, presumably due to deposits of insoluble metabolic products. ll of the species examined displayed a capacity to chemically alter nonpolar nitrobenzene into both polar and insoluble products. olatilization of nitrobenzene from the leaves was a major route of chemical loss.
