The lead exceeds standard the child is injured most
The expert calls upon, the lead is taken in ubiquitously, must hold " the entry is closed " in life
At the beginning of August, the media reports, two villages and 615 children in Shaanxi Fengxiang county suspect the environmental pollution that is caused by the fact that the local east mountain range group smelts the company, cause the lead of blood to exceed standard. At present, 166 children have hospitalized for treatment successively, 449 go on the non- medicine at home and drive the lead treatment.
A few days ago, Shaanxi Province the intersection of Baoji and the intersection of city and department in environment protecting mode announce, ordered the east mountain range in Shaanxi to smelt Co., Ltd. and stop smelting and producing, the company should comment the requirement and implement the measure of rectification and improvement in an all-round way according to the ring, guarantee the discharge up to standard of pollutant; Supervise the green for a long time town polluted to accelerate the relocation progress, will also cooperate with the drawing room in environment protecting mode of the province to assess the blue and green industrialized country of county magistrate of Fengxiang after launching environmental impact at the same time. The incident that lead of this blood exceeds standard, cause the enormous response in the whole country at once. People while the anxious child, pay close attention to the fact the intersection of lead and issue of exceeding standard in the life even more too for these, reporter has interviewed " life Times " thoroughly for this.

Several hundred child blood lead exceeds standard
It is reported emergence of thing want, trace back to will it be March this year, blue and green the intersection of town and the intersection of horse and the intersection of road junction and one 6 year old girl of village, county magistrate of Fengxiang, call, have a stomachache, display agitated always. After being taken and checked to the hospital of Fengxiang county by parents, come out " lead poisoning gastritis " . Later, many villager bring preschool child go the intersection of Baoji and the intersection of city and maternity child care center, the intersection of Baoji and the intersection of city and central hospital, the People's Hospital, Baoji carry on the physical examination too, found finally, all children were in the body the lead content was above standard.
After the incident happens, initiate every concern rapidly. A lot of common people have said to this greatly angrily, and query; Governments at all levels and medical department take the counter-measure rapidly. At the night of August 15, the local department in environment protecting mode announced the investigation of pollution sources monitors the result in this incident, think " Shaanxi east mountain range it smelts Co., Ltd. to be to cause the the intersection of children and the intersection of blood and the intersection of lead and ultra the intersection of target and main cause, do not get rid of the factor with other respects either. "
Why allow to exist for a long time there are smelteries of pollution, endanger to it but is nobody alert? Beijing the public environmental research center director Ma Jun analyzes about " life Times " reporter, two respect problems exist inside: First of all, it is too near that this factory selects site from common people's residence. It is reported, this factory once reached an agreement with the local counties, town governments before founding the factory, government promise points of 3 within the 3 year until 500 ring comment household in the standard range, all move around the factory. However, according to green for a long time chief of town Pu YiMing, because the green for a long time industrial Planning of Expo Garden is adjusted, move and tow it till now all the time. Jun Ma point out lead whom zinc smelt pollute often very much serious while being potential, since so many common people live there, should consider selecting site separately when the ring of this project is commented. Secondly, the situation in violation of rules and regulations of smelting the company and examining finding and exceeding standard three times by oneself of east mountain range, but confiscate and been any penalty note, this comes from being strict in enforcing the law, supervise and do one's best, it monitors and records and clarifies at ordinary times to need relevant department's announcement. On low developed areas such as the Midwest of our country,etc., really some local governments reduce the standard in environment protecting mode, regard this as the favorable condition of inviting outside investment.
Ma Jun still shows, the relevant department claims discharge such as waste water of this enterprise, waste gas accord with the national relevant standard, but not defined this standard is pollutant density standard, or total amount standard. The total amount standard should be set up on the basis of local environment and pollution emission which the crowd can bear, watch from enterprise this to the intersection of perimeter and enormous injury that health brings of community, it discharges total amount and obviously already goes beyond the local environmental capacity. The lesson that this lead pollutes, brief on all parts to need to implement the overall control based on environmental health urgently again.
What plumbous pollution influenced is a colony
In fact, in recent years, Gansu the intersection of emblem and county, the intersection of Fujian and Jianyang, state, Chengde of Hebei and Pi of Jiangsu appear the intersection of children and the intersection of lead and incident of exceeding standard. "It has actually still been the iceberg corner that these have already exposed the incident! " Shanghai the intersection of pediatrics and medical the intersection of face and high the intersection of the Huaihe River and Professor, chief of research office of environmental medicine, children of research institute, engaged in children for a long time lead poisoning prevent from and the clinical treatment is studied, he tells reporters, the main reason that industrial pollution has already exceeded standard as lead at present, once this kind of incident happens, that was influenced is not often one or two people, but a colony.
In his view, there are factories of plumbous pollution, there is risk that lead exceeds standard. It was storage battery trade that stood in the breach. Our country is the big producing country of storage battery, much developed countries do not produce but import from our country. The storage battery exploits from the initial lead ore, smelting, storage battery production, to retrieve finally, will all produce the lead to pollute. Secondly, it is coloured metal smelt, shipbuilding industry,etc.. Live in these " Endanger high " The children around the industrial area, the exceeding standard rate of lead of blood is the most serious.
But Ma Jun points out worriedly, the pollution of heavy metal faces severe reality, especially while the metallic ore exploits and smelts, the poisonous harmful heavy metal is often discharged with waste gas, waste water, waste residue, pollution soil and groundwater, cause the direct damage to peripheral community masses healthily. "The pollution of heavy metal is different from other pollutant, the organic pollution of life can be through degrading naturally, and the heavy metal is not only difficult to degrade, even will collect richly through ground of hundreds and thousands of times of living beings, and then enter the human body through the food chain. " Horse's army calls upon the related departments to review and pay close attention to the fact actively the heavy metal pollutes the question. He thinks, the pollution of heavy metal removes the cost extremely high, the key of solving the problem is to reduce discharge, control the pollution sources completely.
The food, toy have lead " Hide "
Except industrial pollution, a lot of routes may increase plumbous absorption in daily life. Yan ChongHuai says, the exceeding standard rate of lead of children of our country (namely the lead content of blood is greater than 100 micrograms per liter) Had already dropped to 3%-5% from side to side from 40% of the 1990s. But have clinically, still many parents hold children to let him see the doctor very worriedly.
Children have lead to study articles, food, toy, household articles, cosmetics,etc. " Hide " . For example, pencil, oil colour, imitative porcelain tableware, some puffed rice with toy, lime-preserved egg, inferior tin, working out by the traditional method of the coating,etc. sold on cigarette, roadside stand. If disqualification of and the coating of oil color used while fitting up, there is plumbous existence. Especially what deserves to be mentioned is, the electronic rubbish becomes a serious pollution sources day by day in the past few years, the circuit board of the computer is lead welding, the lead content of a computer may be up to 3- 5 kilograms. A lot of are not there are a layer of radiation -proof materials inside the display screen of the liquid crystal TV, may contain the lead about 2 kilograms.
Then, what danger does lead exceed marking? Face Professor say it endanger to 0- 6 children of year old biggest. Have research indicate children the intersection of blood and the intersection of lead and level rise 100 microgram each each time, IQ value will lower 3- 7. When the lead content of blood exceeds each liter for 200 micrograms, how will children move, absent minded etc. to behave; While exceeding each liter for 400 micrograms, will present serious anaemia; Greater than 700 micrograms by each liter and know belly angina, such symptoms as the serious appearance goes into a coma, pulls a muscle. And for adult, the poisoning the standard by the job of national regulation, when namely the lead content of blood exceeds each liter for 400 micrograms, need to observe medical science, it is lead poisoning to be greater than 600 micrograms by each liter and will present symptoms such as limb numbness, anaemia,etc..
Hold " the lead is entered from the mouth " This barrier
"Three major reasons cause the lead to exceed standard and is far greater than adults to children's danger, this just reminds parents in daily life, especially need to pay attention to. " Occupational disease of Beijing Chaoyang hospital and poisoned medical head of the department Hao FengTong and explaining, first, children's gastrointestinal tract have strong absorbability to lead and inorganic compound, the proportion that the adult absorbs is 10% of the intaking amount on average, and the proportion which children absorb can be up to 50%. Second, the lead dust in the air is gathered in 1 meter of overhead spaces more, this is exactly a child main activity space. Third, children are used to using and holding the things in hand, like giving or sucking the finger to the mouth after catching the things, it is apt to cause the lead to enter from the mouth.
The face professor reminds parents, must hold " entry " for the child This barrier. 90% of the lead is from entering stutteringly, the child gnaws the habit of biting the things, eating the finger to give up at will. Must supervise children to trim the nails hardworkingly, wash hands conscientiously before a meal. It can touch the dust in the position to clean children with the clean wet rag to wash toy for children and articles frequently, children's food and tableware should be added and covered dustproofly. In diet, should guarantee nutrition is balanced, often eat and include calcium sufficient dairy products and soyfood, and the liver of animal, blood, meat, eggs, marine product with abundant iron, zinc, there are fresh vegetables, fruit enriched with vitamin C,etc..
The face is high the Huaihe River is reminded finally, can't use medicines to arrange the lead blindly. In each liter for 100- 250 micrograms, adopt nutrition to intervene the means as to the lead content of blood, for example let the child drink more milk, eat the egg, supplement more calcium, protein, vitamin,etc.. And while exceeding each liter for 250 micrograms, after needing to drive the plumbous test in hospital, determine that use 2 sulfhydryl- man 2 sour etc. and rank lead medicines.
