Plants purify the air of mercury pollution

Pa ∞ ∞ extension 060 for a copy of 2000 China Environmental Health Volume 3 of the total G 3,4 l1, l2 on the growth in Shanghai Commonly found in 22 plant species monitoring. Leaves the highest mercury content was followed by the melon to the magnolia Yellow Yang, Pittosporum,[link widoczny dla zalogowanych], mosquito female,[link widoczny dla zalogowanych], Mexico, cypress and palm. This shows that seeds and other mercury vapor Huang Yang has a strong anti-drug accumulation capacity and performance, it enriched the atmosphere about 100 times the background value of the amount, and growing well. The Magnolia, Platanus, loquat, azaleas and other plants leaf leaves hair mercury content than the end. This may be the surface of plant leaves with different quality and variety of plants on breathing rate. Specific factors still need further study. In this paper, the strongest of the seeds of mercury concentration in air purification boxwood material for passive absorption of plant laboratory simulation experiments can be seen from Figure l, with the mercury vapor inside purification plant, the first 2 days of mercury concentrations fell by 65 %,[link widoczny dla zalogowanych], and then maintained at a low level. Downward trend from the cabinet that the concentration of plant uptake is in line with the principle of gas diffusion 'm]. That is, in a certain range of concentration, diffusion and transfer of the amount of exposure time of plants around the concentration and proportional to the product. Mercury absorption boxwood seeds and c × T showed a linear correlation,, = n980 highly significant, the regression equation Y = bxo boxwood seeds mercury absorption capacity of J for the C × T,[link widoczny dla zalogowanych], b for the regression coefficients, both breathing rate. Seeds used for experiments boxwood leaf area of 0.13 tin, calculated inspiratory rate 0.133mS / h / Ⅲ 2. Mercury pollution in the environment of the purification treatment, in accordance with the contaminated area and breathing rate of the plant to be placed in determining the amount of plant available basis. Laboratory simulation experiments in plant and breathing rate obtained on the basis of site effects were observed, can be seen from Figure 2. Huang Yang melon to be placed in mercury processing plant in the leaf area and interior volume ratio of about 0.55 when the effects of mercury reduction of 60%. Huang Yang melon to be placed in the outdoor yard waste, due to the formation of the mercury pollution around the plant seeds Huang Yang barrier, so ambient air mercury concentrations decreased gradually, although the experiment, the temperature rose to 40 ℃, but the mercury concentration in air has fallen 47%. This further reduces the air concentration of mercury in plants is feasible. Use of plants to reduce mercury concentrations in the air following the conventional physical and chemical methods and then a new approach. Its principle is to disperse the pollutants in the air together. So as to achieve the purpose of reducing mercury concentrations. Indoor and outdoor plants can not only beautify the environment,[link widoczny dla zalogowanych], but also the prevention of pollution of the good material.
