Lock the pollutant of characteristic in several minutes
It is reported ' Reporter's ginger splashes the reporter Fang ShuFen) The environmental pollutant looks like the enemy coming to stalk frequently, should identify, often need to take a sample through the material object, go on than to the experiment again and again, could learn which kind of pollution it is on earth. This cycle, it is even longer to usually take one week. But the fast detection system which East China University of Science and Technology Professor Long YiTao,etc. developed, let this course not become complicated any more: Collect all " Unidentified enemy " Set up huge database in identity characteristic, can be within shortest several minutes, longest hour, lock the goal and take the effective measure rapidly.
Professor Long YiTao presided over the subject, " fast detection technique system of pollutant scene of the great environmental contamination accident characteristic " by name . It is introduced, the environmental contamination accident of pollutant of characteristic has characteristic such as being sudden, unknown, so must in most short time, the main enemy - -The pollutant of characteristic is locked, then take out the corresponding countermeasure.
Calculate according to a report of Chinese Academy of Sciences, though our country has about 10% of economic growth rate every year, but the losses arising from environmental pollution and ecological disruption have already accounted for 15% of GDP total value. Need the intersection of pollutant and about more than 60 kinds that pay the utmost attention to in the of our country environment at present, the characteristic is measured fast at pollutant scene, but the one that take place in pollution is as soon as possible, to these " The unidentified enemy " Arrange to check, measure the pollutant kind, pollute range, biological toxicity and extent of injury, offer technical support for environmental risk assessment and decision of meeting an urgent need, if accomplish this, it is significant to protecting the environmental security. However, this kind of technological products is still basically the blank in our country. Once happen environmental incident, great majority can only take a sample, send laboratory to pollutant, measured with the large-scale instrument by professional personnel.
The reporter learns, the fast detection technique system of scene that East China University of Science and Technology develops is one examined by synthesis that portable high sensitive integrated checkout equipment and an intelligent analysis software form Examine the analyticl system. "The portable instrument case is of the same size of first-aid kit, even can draw and point out operating with several cartoons. " Such as many passway biology sensors, specially direct against the fast detector of organic phosphorus, amino first acid ester pollutant, so long as it can measure the result in 10 minutes, accuracy is more than 90%. Give out light bacterium, spend acute biological toxicity of pollutant on measure. Because of microbial toxicity and the intersection of fish and toxicity and even exist, concerned with while being a certain among the human toxicity of chemicals, therefore can replace other toxicity to test with microorganism's toxic test, its advantage is that a cheap and toxic effect of the expenses is quick, test period shortens several times and even thousands of times than the regular toxic test of fish.
"Our ' the enemy ' is fuzzy, therefore it needs many kinds of different professional backgrounds such as environment, analytical chemistry, electrochemistry, information, mathematics, nanometer to set up this technological system. Cross, permeate the characteristic that is our subject multi-disciplinarily. " Dragon's professor says, " we should have independent intellectual property right, characteristic thing, the goal is the industrialization, because the actual using value of this kind of product is very big, to this subject, the country has more than 10 million yuan to allocate the fund. "
