The food security needs to assess in an all-round way " many experts discuss " Reasonable
Have centred on all sorts of disputes of the food security recently, strive a common understanding to happen: Need " many experts discuss " . To the same concrete problem, the experts of different trades such as chemistry, medical science, public health, agriculture, there are words that can say, but because of professional limitation and this or that " interests connection " ,It is impossible " It is complete to speak the words " ,Still give tit for tat each other sometimes. All sorts of statements appear on the media separately, ordinary people feel " a statement, a statement of tomorrow of today " ,At a loss as to what to do, to " expert's view " gradually Grow the doubt out. The such one is entangled with pointing out us: Reporter and reader, professional background and possible interests background all looked out for him while listening to expert's view, understand this is " The statements of a school " Not " A speech is decided " ; It is set up that the media is necessary " Many experts discuss " The platform, present many kinds of sounds in front of readers at the same time. Different visual angles, different views Get, mould, take pharmaceutical from pairs of feeding bottle, A of phenol, plastics and chemistry have encountered " trust crisis " again recently ,This makes professor of Fudan University department of chemistry Liu Dan very worried at the beginning: "I listen to a lot of people shouting, ' chemistry don't injure us again! ' how is chemistry in the inflictor woolen cloth? Without plastics, human life is not so excellent! " He says, the plastics are a piece of good things, the birth of a series of macromolecule synthetic material, have brought a great deal of advantages to mankind. Say the feeding bottle, the high temperature resistant glass feeding bottle, but fragile, the weight is heavy, it is worried that children hold, the plastic feeding bottle is better. In his view, so long as popularize some general knowledge, can let everybody rest assured to enjoy the facility of the plastics, for example " don't put any plastic products into the microwave oven forever " . Because the microwave oven heats the irregularity frequently, it is too high at some position temperature, some plastics will be softened, deformed, and precipitate to get some poisonous harmful substances. But the chemist's view, public medical and health experts do not approve very much. "The plastics have really facilitated our life, but how is it to healthy influence, can't do optimistic to comment on, remain, study easily. Certainly this could draw a conclusion through a large number of animals, human experiments. " The nutrition of Fudan University and strict dawn professor of teaching and research chief of the office of food hygiene say to reporters like this. Have studied and moulded and melted pharmaceuticals already for 16 years in strict dawn. He say, hot steamed bun, corn being excellent to put plastic bag into, scribble perfume, nail polish, hair finalize the design ink, the ones that may all be exposed to appearing mould and melt pharmaceuticals. Though seen from present research, the quantity of moulding and melting pharmaceutical of appearing in the plastics package is very low, and can discharge with the human supersession; But if someone abuses the food of the long-term edible plastics package, it is difficult for his consequence to play the final conclusion. Will the rice add preservatives? Some experts object to clearly: "So long as rice controls the good moisture can keep fresh - -Control the moisture about 12%, it is out of question to eat within quality guarantee period. Why spoil the effect by adding what is superfluous with any preservative? " This is a public medical and health expert's view, they pay close attention to the health. But some agricultural experts are disapproving: "Certainly put some preservatives. Most rice, from afford to plant, some pile a couple of months in warehouse, how can it be carried on if not putting? " Professional background, interests connection " explosion water-melon " After appearing, the agricultural expert claims, can not " devilize " Bear fruit clever expanding pharmaceuticalling,etc., " if suitable time and place plant the intersection of vegetables and melon and fruit, will borrow them to assist and grow, guarantee ripely soon, in this way people could be limited and enjoyed all kinds of vegetables and fruits by season, region. " In their mind, this can be rated as " great progress of agricultural technology " . But a doctor's words are refuted fiercely: "Is it still the deficient times of material now? Dining table of us already very abundant, go, produce in a large amount, violate natural law against the season food and then, responsible for human health no, will bury the hidden danger in the body! " The doctor's words, agriculture studies the family and does not like hearing: You said you pursued the natural food, did organic agriculture for the health, but the land is limited, " some experts' romantic view is not geared to actual circumstances " . The meaning between the lines, it is essential for agriculture to increase the production of technology. The chemist Liu Dan says too at the beginning, the macromolecule synthetic material is a very meaningful invention, the natural resources is limited because of population explosion on the earth, the mankind have to try to reply; Just, people should take care of some side effects while using. For example some plastics will appear " Pair of phenol A " , initiate the sexual precosity, our country has already too recently stipulated that forbids including" a pair of phenol A " Feeding bottle list; For example fitting up the house should use the panel again, but forest and natural timber are limited, the intersection of someone and the intersection of invention and conglutination and wood-based plate that become, binder will release formaldehyde - -The experiment proves, formaldehyde has certain release period, so our country stipulates the wood-based plate just made should be put for some time and just used through measuring. "Can't say carelessly chemistry is not good. It is unrealistic to pursue simply pure naturely. " He says. The expert can not see eye to eye, visual angles that leads to the fact except the professional background are different, represent different interests too sometimes. Public medical and health experts have given reporter an example: We often criticize the feeding for abusing antibiotic, much pharmacology family says this causes the human body to produce a great reason why antibiotic is able to bear nature. But antibiotic gets the recommendation of some agricultural organizations, they stand in the angle protecting agricultural development and peasant's interests, pay close attention to the fact even more " if domestic animal, chiken and duck, fishes and shrimps are ill and dying, what are peasants to think that grow? " Assess in an all-round way, clarify pros and cons "Discussing the question of food security, we should invite the experts of different fields to together, scrutinize with more visual angles, clarify pros and cons, presume more scientific norm. " The experts have had a common understanding in disputing gradually. The reporter knows, " Committee of Experts of risk assessment of the food security " of the national aspect Have already introduced " Many experts discuss " . "For carry on overall intact assessment to some the intersection of food security and issue, must assemble blow relevant in various fields expert. The risk assessment panel of the food security has medical science, food, chemistry, toxicologic expert to participate in. " The food chief of research institute Ma ZhiYing in Shanghai introduces, all parts including Shanghai have already set up such a local group correspondingly. But the expert points out, present " many experts discuss " Generally " Set up if have any further problems " ,This is not enough, need " moving in front of the pass " : "Such as some examination and approval links related to food security, should ask the expert from various places to participate in together.
