Description
Technical field
The invention belongs to environmental monitoring field, disclose a kind of saprobe toxicity on-line monitoring prior-warning device, be specifically related to a kind of fish acute toxicity on-line monitoring analytical equipment.
Background technology
Along with the fast development of industry especially chemical industry, poisonous dangerous material in production, store, Sudden Environmental Pollution Accident enters water body frequently in transportation, the aquatic ecosystem of depending on for existence to the mankind causes serious destruction.In order to ensure the safety of water body especially potable water source district, the various burst water pollution accident of reply fast, exploitation fast, the technology of accurate evaluation each pollutant toxicity seems particularly urgent and important.
Through the development of many decades, the sensitivity of various physico-chemical analysis means is more and more higher, more adequately can assess pollutant to the impact of biology by dose-effect relationship.But these class methods have following several limitation and deficiency: the chemicals (1) touched in our daily life reaches 4-8 ten thousand kinds, these materials have the possibility of polluted-water, and it is very limited to relate to index in routine monitoring, can not monitors one by one each pollutant and identify; (2) mostly pay close attention to Single Pollution thing to the toxic effect of aqueous bio, in fact water body is not unitary system, but each pollutant is worked in coordination with, antagonism, superposition etc. synthesis result; (3) evaluation criterion lacks scientific, even if every physical and chemical index is all up to standard also may not necessarily illustrate that water body is definitely healthy.
In fact, toxicity is a complicated biological phenomenon, and pollutant is harmful or harmless to biology to only have biological test to judge, differentiates the collaborative still antagonism of mixed pollutants performance.Therefore develop sensitive, biological toxicity tests and early warning technology are the Main way of reply burst water pollution accident accurately.
Aquatic toxicity on-line monitoring common at present mainly comprises fish, photogen Daphnia magna, algae etc.
Its Mesichthyes is much more responsive than the mankind to the reaction of water pollution; when occur in water body such as oils, poisonous dangerous material reveal or by people for poison etc. burst accident time; often there is abnormal movement or mass mortality in the short time in fish, can very intuitively open fire matter be polluted suddenly.In toxicity in fish method of testing, because the similarity of zebra fish gene and human gene reaches 87%, generally choose the indicator organism of zebra fish as biological monitoring and early warning.
Simultaneously by monitoring index simple, the test period is long, testing cost is high, be subject to the impact of the shortcomings such as the extraneous factor such as water temperature, bait interference, the range of application of toxicity in fish method of testing is subject to a definite limitation.In fact these shortcomings are main has much relations with the bio-toxicity characteristic manner of current China.Current China adopts 96h or 48h MLC (median lethal concertration) (LC50) characterization method.Its shortcoming is, the water body (as variety classes pesticide wastewater) that differ greatly complicated for water quality, LC50 concentration difference may be very large, is thus difficult to setting one comparatively reasonably concentration limit, larger on the accuracy impact of result.
And the developed country such as the U.S., Germany all adopts extension rate bio-toxicity characteristic manner at present.As U.S. EPA adopts " toxic unit (TU) " to express, acute toxicity unit TUa=100%/LC50.Wherein LC50 water body dilution ratio is expressed, according to TU value, waste water is divided into 5 grades: grade I (TU < 0.4 is nontoxic), grade II (the micro-poison of 0.4≤TU < 1), grade III (1≤TU < 10 is poisoning), grade IV (the high poison of 10≤TU < 100), grade V (TU >=100 severe toxicity); According to the result of parameter in bio kinetic model, based on toxicity grading system, carry out the safety evaluatio of environmental water sample. the method has fully utilized the result of multiple parameter in bio kinetic model, intuitively can characterize the size of water body to bio-toxicity, there is the advantages such as simple to operate, testing cost is low, visual result is sensitive, be worthy to be popularized.

Context of detection: the image processing module Real Time Drive of main control module 1.1 controls the footprint that video camera 5.2 records fish in each cultivation cup 4.3 in sensing range; According to different reaction time and water sample blending ratio, by recording the zebra fish active situation (as travelling, dead etc.) of each cultivation cup 4.3, and then calculate the average T U value of often group cultivation cup 4.3, by contrasting with water body acute toxicity evaluation criterion, the acute toxicity grade of this water body can be determined.
Especially in the burst pollution situations such as noxious material leakage, as unexpected strenuous exercise or long-time without abnormal occurrencies such as motion tracks in the short time appears in the fish cultivated in cup 4.3, then automatic trigger alarm prompt facility, reminds staff to rush for rapidly scene and carries out emergency processing.
Certainly; the parameters such as the pump number set in above-mentioned explanation, cultivation cup group number, often group cultivation cup number, water sample blending ratio are not limitation of the present invention; in essential scope of the present invention, the change made, remodeling, interpolation or replacement, all should belong to protection scope of the present invention.
