Description
Technical field
The present invention relates to a kind of method of utilizing algae to carry out aquatic monitoring, more particularly, relate to a kind of by observing the photosynthesis that can carry out photosynthetic algae such as green alga come the particularly method of water body environment of monitoring of environmental.
Background technology
Usually, utilize biologies such as fish, shellfish the method as area monitoring nuisance incidents of leakage such as rivers to be called as the method for biological monitoring.Since in the later stage seventies, whether Germany utilizes the method for fish or water flea etc. to be determined to have in the water system that comprises lake, river noxious material to invade, and comprises the biological monitoring system that begins one's study of the many countries of New Zealand, Belgium, France, Switzerland, Austria, Britain or the like.So far, be suitable for measuring the different aquatic organisms whether water system has noxious material to invade, carried out various research at those.Also therefore proposing many abnormal behaviour pattern analysis of aquatic organism or biological natures utilized monitors the method whether water body pollutes.
As in the biological monitoring that utilizes fish to carry out, people are to the behavior pattern of fish, as swim, Ambient, bunch, scatter and move about and carry out observation analysis.If the abnormal behaviour pattern appears in the fish of observing, just indicate the pollution of water system, as being arranged in the water system, noxious material invades.
Yet, influence the environmental factor that not only comprises noxious material of fish behavior pattern, and also have internal factors such as other healthy fish situations or other instinct requirements.Therefore, caused such problem:, the error of measuring usually occurs because the causal relation between behavior pattern of fish and the water pollution is not tight.
Furtherly, only when pollution level exceeded predetermined extent, water polluted the behavior pattern that just can influence fish.Owing to do not reaching under the situation of predetermined extent, the behavior pattern of fish will can not change, and whether this just can not mensuration exist water to pollute.And, even polluting, water goes beyond the limit of degree, and fish can not show the abnormal behaviour pattern immediately yet, and kind and degree according to polluting have certain preclinical delay, just can show unusual.That is to say that fish are less relatively to the susceptibility that water pollutes.
A major subjects of research biological monitoring improves this causal relation and susceptibility exactly.
Although water flea shows stronger this causal relation and susceptibility, but still abundant inadequately.
Effective method is to utilize luminescent microorganism recently.
Korea S 10-0262681 number, of E.I.Du Pont Company (E.I.Du Pont De Nemours and Company) is called the patent of " monitoring of environmental is polluted high responsive method "; Korea S 10-0300445 number, of Ou Shengken (Seong-Keun Oh) is called the patent of " utilizing luminescent microorganism to continue to monitor the Method and kit for of noxious material in the water system "; Ou Shengken (Seong-KeunOh) Korea S 10-0305218 name is called the patent of " utilizing fixing luminescent microorganism to measure the equipment of water toxicity automatically "; The LG company of Korea S's publication publication (Korean Laid-Open PatentPublication) number of the edition 2000-0024847 record (LG Industrial SystemsCo., Ltd.), name is called the document of " utilizing the fixedly method of luminescent microorganism and bio-sensing instrument mensuration noxious material "; Hundred O 'Neills (Bioneer) company of Korea S publication publication number of the edition 2001-0086342 record, name is called the document of " equipment that continues test water toxicity ", and other patent documents all disclose the technology of utilizing the luminescent microorganism monitoring of environmental to pollute.

Influence photosynthetic factor light intensity, gas concentration lwevel and temperature are arranged.That is to say that the photosynthetic total amount of healthy photosynthetic vegetable cell only is subjected to the influence of said external factor, is affected by other factors hardly under the situation of getting rid of the cell health condition.
According to the difference of influence factor, the variation of concrete vegetable cell photosynthesis quantity can be obtained by experiment in advance, and if the quantity of cell enough, then the probability that exists of healthy cell descends to some extent according to the difference of environmental baseline separately under normal distribution.
That is to say, can estimate that under varying environment condition separately, if award compensation according to the variation of influence factor, the photosynthetic total amount of capacity vegetable cell is similar to a steady state value.
Simultaneously, the healthiness condition of metaphyte needs the plenty of time with the variation of environmental factor, and on the contrary, healthiness condition and the metabolism of one-celled plants almost change immediately with environmental factor.

Another object of the present invention provides a kind of method of environmental monitoring of monitoring of environmental pressure of the photosynthesis total amount by observation photosynthesis algae.
In addition, consider each luminous energy that can realize photosynthetic surperficial incident stream, the part of luminous energy at first by each surperficial reflex as catoptrical energy to external radiation, the luminous energy that only retains is absorbed for each individuality.Be the energy of individual bulk absorption, major part is used for photosynthesis; The energy part that is not used for photosynthetic absorption then is converted into heat energy, and to each individual external release successively, energy remaining is converted into light wave to each external body radiation successively.
For body absorb to the light wave of external radiation and incident light or reflected light without any getting in touch, have single-frequency according to the difference of species.This light wave is also referred to as fluorescence.
In luminescent microorganism routine luminous, light wave is in the certain frequency scope, and this scope comprises visible light; This is luminous can not to have spontaneous generation under the situation of extraneous incident light, and to extraneous radiation.Opposite, when incident light disappeared, fluorescence mentioned above disappeared immediately or after the lasting short period, and had a wavelength that exceeds visible-range usually.
Experiment finds that intensity of fluorescence is inversely proportional to photosynthetic total amount.That is to say that when individuality was finished photosynthetic the work, fluorescence intensity died down; Otherwise, when because metabolism and healthiness condition unusual, when the photosynthetic activity of individuality weakens, the fluorescent brightness grow.
Therefore, the method for environmental monitoring according to the present invention utilizes photosynthetic algae, by measuring the fluorescence total amount, observing photosynthetic total amount, and can monitoring of environmental pressure.
