Abstract
The present invention utilize to belong to the biological monitoring thing of the Nostoc commune of cyanophyte as the monitoring atmospheric pollution, and the present invention has that the monitoring distribution of material is wide, life span is long under the drying regime, can carry out long term monitoring to the atmospheric pollution situation.Monitoring result can be unified the advantage of comparison.
Description
The present invention relates to a kind of biological monitoring thing that is used to monitor atmospheric pollution, utilize this biological monitoring thing to adsorb pollutant in the atmosphere, final test analyzes the adsorbed pollutant of biological monitoring thing, determines the contaminated situation of atmosphere.
The best atmospheric pollution biological monitoring thing that is now adopted is bryophyte (this method is at first proposed in 1969 by G.T.Goodman and T.M.Roferts).Bryophyte does not have taproot, is not subjected to the interference of material in the deep soil matrix, plants the surface and does not have cutin membrane, and pollutant enters in the plant easily.Because above advantage, it is more extensive that bryophyte is used in the atmospheric surveillance field.But, liver moss is not long in the following time-to-live of drying condition, and is limited with a kind of distribution region, and this makes utilization produce the difficulty of drawing materials when material is monitored with a kind of the monitoring, and when carrying out atmospheric surveillance with liver moss not of the same race, be difficult for the pollution condition of different contaminated areas is compared.For example, the bog moss that Efficiency in Buildings in Tianjin Area is distributed more widely, it is the used a kind of monitoring thing of Efficiency in Buildings in Tianjin Area, and this liver moss does not distribute in the NORTHWEST CHINA area, when carrying out air monitoring adopt local certain liver moss distributed more widely, as being to adopt the high-quality green tea moss in the Baiyin area as the monitoring material in the northwest more.Obviously, the test result of two places atmospheric pollution can't compare.
Task of the present invention provide a kind of overcome the prior art deficiency, wide as a kind of region that distributes, gather easily, life span is long, measured result can compare under the drying condition biological monitoring thing.
The used biological monitoring thing of the present invention is for belonging to the Nostoc commune (Rostoc commune vacucher) of cyanophyte.Nostoc commune all has distribution all over the world, it plants the differentiation of body unrooted, stem, leaf, is not subjected to the interference of deep soil matrix thing in growth, plants the surface and does not have cutin membrane, and have sponge shape structure gelatinous sheath, assembles the pollutant in the atmosphere easily.Test factually and show, Nostoc commune still long-term surviving, not characteristic of misconvergence collection atmosphere pollution under drying regime.
When Nostoc commune is used to monitor atmospheric pollution, can adopt following method: with air-dry after Nostoc commune water, distilled water and the washed with de-ionized water of gathering, taking out a part uses as the test background values, other gets a part and packs in plastics mesh bag or the metal mesh bag, hang on the suitable height of monitored point, behind certain hour, will in drying baker, dry behind Nostoc commune taking-up water, distilled water and the deionized water rinsing in the bag, use conventional method assay determination pollutant load then, the content of being measured deducts background values, is the accumulated value during the monitoring.
Great advantage of the present invention is that the monitoring distribution of material is extremely wide, and distribution is all arranged all over the world, gathers easily, is convenient to various places and gathers materials on the spot.Because the result after the monitoring can compare, help carrying out unified on a large scale monitoring and to the appraisal of various places pollution condition.It is documented that Nostoc commune can be survived 87 years under drying regime.Therefore, Nostoc commune also can be used for the long term monitoring to monitored point.
Below provide one with the example of Nostoc commune to the somewhere fluorine pollution monitoring:
The fluorine-containing background values of used Nostoc commune is 0.65-0.85ppm.With the mid-3 gram Nostoc communes of sampler bag (nylon net bag), place 32 days post analysis, its fluorine content is 60.05ppm.To have compared conspicuousness relevant with placing lime filter paper in the same time and place for its result, hangs bag with liver moss and be in a ratio of height correlation.
Utilize the monitoring of Nostoc commune, also have in the experiment and the similar result of last example similar heavy metal and inorganic pollution in the atmosphere.
