摘要

Assessment of atmospheric pollution and environmental hazards. Email: wukong6106@163.com Abstract: The presence of heavy metal fine particles in the atmosphere has a negative impact on the early growth of terrestrial plants. By establishing a reasonable exposure scenario and simulating different levels of atmospheric pollution conditions during the early growth stage of plants, evaluate the effects of heavy metal fine particles containing Pb and Cd on the biomass of rice and potato, including seedling emergence, seedling growth, and fresh weight (both terrestrial stems and leaves and underground tubers). The results showed that the concentrations of Cd and Pb elements in the artificial soil of the exposure treatment group increased at the end of the experiment, with Cd element concentration increasing by about 8.8 times compared to the background value, while the increase in Pb element concentration was not significant compared to the background value. The enrichment levels of Cd and Pb in the stems and leaves of rice on land were 0.0020 mg · kg-1 and 0.054 mg · kg-1, respectively; The enrichment levels of Cd and Pb in the underground tuber of potatoes were 0.185 0 mg · kg-1 and 0.074 mg · kg-1, respectively. After exposure treatment, the inhibitory effect on the various biomass endpoints of rice was not significant, while the inhibitory rate on the fresh weight of potato underground tubers reached 27%. It can be seen that under simulated exposure conditions, the concentration of Cd pollution elements in artificial soil changes significantly, and the underground tubers of potatoes have a significant effect on Cd enrichment. Compared with the blank control group, the combined pollution of Pb Cd heavy metals caused by exposure treatment significantly inhibited the biomass of potato underground tubers
