The specific breast milk sample in Zhejiang measures and finds the residues of pesticides
Want to examine hormone of breast milk originally, but find " pesticide " The baby's perfect food - -The breast milk has a potential risk too. Hangzhou have mother peddle fresh breast milk on the net, claim " pure people's milk " ,Healthy nutrition. Recently, in province Center for Disease Prevention and Control, staff members but finds in detection impressively: In more than 20 copies of breast milk sample, among them find the residues of pesticides individually. Become the doctor measuring and say too that feel it very together " Startled" ,Furthermore let people feel a surprised one is, composition of this pesticide is to stop using DDT (an organic chlorine pesticide) for the past 30 years at home . Consider babies are healthy, staff members have already proposed the hosts of these samples - -Several mothers had better stop the breast milk and feed the baby, use the milk power instead and fill a prescription to feed manually. These hosts who measures the sample, the reporters knows, all come from Zhejiang countryside. Want to examine hormone of breast milk originally, but find " pesticide " According to the introduction of staff member in the centre, the reason why cooked the breast milk to measure, originally wanted to examine " hormone " in the normal breast milk Content, cooked a reference for the milk power on the market. In in not measuring make staff member by residues of pesticides by the way test, it is there is breast milk really to never expect " " . What situation is it on earth? No matter put down a professor after the reporter has asked the province diseases to accuse of the central physics and chemistry. Let, put down professor engaged in more than 30 years such as monitoring such as medicines such as food, especially good at the detection of food additive, it is the expert. Tie any say have micro- pesticide in the ordinary human body, what news it is not, so long as not the exceeding amount, does not have anything that influence to people's health. In the world, the situation with extremely micro- pesticide is not rare in the breast milk. It is decomposed, can enter the human body from the food chain that DDT is difficult The reporter knows, our country has already forbidden DDT to use in the crops as pesticide as far back as 1983. Why already stop using pesticide for the past 30 years, will enter the human body? Let, equal Professor, give reporter last time popular science course: Though DDT is out of use in agriculture already, the shape of this kind of material is stable, it is generally acknowledged that will not decompose in 50, so remain as before in the soil, water body. Take the post as the professor and say, not only our country, a lot of countries in the world face DDT and remain the problem. 20 years ago, he once went to Germany to exchange and study, there were scientists in Germany to find DDT in the breast milk to remain at that time. The regulation for a time of some cities in Germany, the breast milk of first is not fed first, let the lying-in woman cook breast milk once to measure, see whether there is pesticide DDT that remains. Pesticide of detection in the breast milk, there are reports early both at home and abroad Breast milk no " Safe " ,Return detection " Pesticide " ,The reporter surfs the Net to inquire, find this phenomenon is not rare, as early as more than 20 years ago at once, the domestic and foreign literature has relevant report and research, the domestic and foreign media has similar reports that is found in recent years, the detection in the breast milk " Chemical composition " . " scientific Times " has reported, researchers detect " fire-retardant pharmaceutical composition of bromine " in animal food and breast milk ,Perhaps have toxic effect on hepatocyte; China Center for Disease Prevention and Control Wu would rather seminar,last 12 more than 1000 breast milk samples of province, find it in the breast milk sample " Six bromine ring 12 alkane " Level of pollution,similar to Europe, American and other countries in Asia; U.S.A. " association of environmental protection of California " Carried on an experiment regarding the breast milk pollutes in 2005, measured 40 women's breast milk samples of area of the northwestern part of the Pacific Ocean, in the breast milk of woman of 30% of result " Much bromine unites benzene ether " The content is a bit high The reporter has interviewed relevant experts for this, they say: Measure similarly and only direct against some samples, for most people, the breast milk is still baby's safest food, parents needn't feel panic to this. How did pesticide enter the human body? DDT also calls DDT, the Chinese name is from the English abbreviation DDT (transliteration) And come, white crystal, insoluble in water, soluble in the kerosene, can make emulsions, it is the effective insecticide. Will it be first half the 20th century, prevent agricultural plant diseases and insect pests from, lighten the intersection of malaria and typhoid fever, wait for disease that mosquitos and flies travel play much role while endangering. But because it too serious to environmental pollution, steady to decompose while being difficult in environment, a lot of countries and regions have already forbidden using at present. How did it enter the human body? Pesticide enters the human body, there are such a food chains: DDT that exist in water body perhaps density very low, but planktonic organism, alga in the water body will take, stock DDT as " nutrition " ; Subsequently, the fish eat up alga and planktonic organism in the centre, the content of pesticide concentrates on fish's body. Finally, the intersection of people and terminal station in food chain, take, enter after the fish, fish residual pesticide right away enter the human body in the body, deposit. Pesticide in the soil, can reach in the human body with terminal food chain finally through the similar food chain too. DDT enter food chain is can in the intersection of animal and rich collection in the body finally, not only mankind, falcon, bald hawk and osprey have too in the these birds. Can DDT be discharged outside the body? The reporter knows, DDT is extremely apt to accumulate in the fat of human body and animal's body, accumulate it in the course, DDT accumulating in the adipose tissue is very big at first, slow down to some extent gradually later, been reaching a kind of steady density all the time. Because DDT is difficult to discharge outside the body through the supersession, so is just easy to understand, why present DDT in breast milk.
