The expert of Chinese Academy of Sciences claims the hormone content of fish of the Changjiang River is not enough to endanger the health
A few days ago, the international environmental group " green peace " Release the survey report and claim, in taken from the Changjiang Rivering, downstream when the carps and Nian's fish of 4 cities of Chongqing, Wuhan, Nanjing, Maan Mountain cook and measure, measure, known as" Environmental hormone " Ren base phenol and it is hard base phenol,and can last sexual precosity waiting for development and reproductive system issues female these two kinds of materialses. To report this, yesterday, Chinese Academy of Sciences aquatic so and the intersection of Central China University of Science and Technology and environmental relevant expert of institute respond one after another: Some wild fish really have a hormone situation, but the hormone content is not enough to be detrimental to health. Survey report: Two kinds of fish of the Changjiang River include environmental hormone and cause the sexual precosity This share reports the question is <<" poisonous " Latent in the river - -The poisonous harmful substance is investigated in the body for the fish of the Changjiang River >>,Paper of 24 pages in total. "From January of this year to March, the investigator gathers wild carp and Nian's fish in the Changjiang River in four cities along the Yangtze River, fresh living river fish that all samples offer by local fisherman. The sample is frozen and kept in shade by the tinfoil paper wrapper after collecting, transported to the research laboratory located in Britain Exeter university subsequently. " Test reveals these fish have accumulated noxious substances such as phenol, hard base phenol of Ren's base,etc. in the body in various degree. The reporter, " phenol and hard base phenol of Ren's base is extremely common chemical raw materials in detergent, textile products and leather are covered, with paints, it is environmental hormone, can interfere with endocrine interferon of endocrine and influencing development level. "These materials have accumulating nature in the organism, can enter the human body through the food chain, form the hidden danger of the health. " It is said that the person who releases report is military and firm and beautiful, " because these materials have enormous negative effects on environment and health, a lot of developed countries and regions have already classified it as chemical material forbidden or exercised restraint in using. " The expert responds: Researcher, ecotoxicology expert Zhou BingSheng verifies while giving an interview yesterday that there is hormone but not enough detrimental to health Chinese Academy of Sciences is aquatic, the domestic fresh-water fishes include living in the fish of the rivers, lake, reservoir, because of the influence of the water pollution, it is more common to contain phenol and hard base phenol of Ren's base in the body. Measuring the instrument at present can detect fish's very slight phenol and hard base phenol content of Ren base in the body, but domestic not to presume the relevant standard to phenol of Ren's base and hard base phenol upper limit of content in the food yet. Zhou BingSheng says, phenol of Ren's base and hard base phenol impact on health exist in theory, but what intensity is influenced, remain to further study, there is not a clear conclusion at present. Basic president of medical college, amynologic expert Professor Tan JinQuan of Wuhan University expresses hormone content of 85.0 micrograms / kilogram in the report, will not cause and obviously endanger the human body. Environmental institute's associate professor Wu XiaoHui of Central China University of Science and Technology points out, are " known as Ren's base phenol and hard base phenol of ' environmental hormone ', it is ' poisonous ' in the river fish whether to cause or not, it depends on how much the content of harmful substance is, only when accumulating to a certain amount, it is sure to damage to cause the human body " . The person who releases report: The noxious substance is being accumulated qualitative change yesterday constantly to cause, military and firm and beautiful that reporters were bringing the queries from all walks of life and interviewing the persons in charge of this organization, person who releases report. Reporter: There are environment and medical treatment expert that think, the environmental hormone that the river fish include is not enough to produce greater danger to the human body at present, have you exaggerated and endangered? Wu YiXiu: Will have danger getting instant result on human body if not explaining and taking the fish which contains environmental hormone in the report. The basis reported is that it is harmful to human body to already confirm phenol, hard base phenol and the whole Fluorine hard alkane sulfonic acid of Ren's base in the world. How much be harmful to human body as for concrete content, there is not a unified standard yet in the world at present, but the one that can affirm is, as the constant accumulation of the harmful thing quality certainly will cause the qualitative change, just question of morning and evening. Reporter: Is the sampling method that the sample that the survey report takes measures scientific? Wu YiXiu: Before determining to take the detection method of sampling, our organization had consulted a lot of experts in environment protecting mode, they show, enough to support and report contents talked about by way of sampling and measuring, report finally that hopes to prove a fact - -The fish of the Yangtze River valley contain some noxious substances in the body, but not want proving every fish in the body, every section and have. How does the expert give an idea to take precautions against environmental hormone So-called " environmental hormone " ,Mean that releases on the environment, influences the chemical material of people and animal endocrine system because of human production and living to move about, because it has " Similar " The function of estrogen, call it " other source endocrine interference thing " on academy . How to come to take precautions against the danger of environmental hormone, the expert provides some suggestions: For example, don't steep the instant noodles with the foamed plastics container and facilitate the face device 90% are the foam styrene products, it is a kind of carcinogenic environmental hormone; Don't put the polyvinyl chloride packaged food in the microwave oven and heat, because under the high-temperature condition, a pair of phenol A of environmental hormone will be oozed out from it; Use to containing medicine of hormone carefully; Edible brown rice, buckwheat, spinach, turnip,etc., it is apt to make Great Britain of environmental hormone two discharge from the body; Drinking more tea helps environmental hormone in the viscera to discharge outside the body too.
