Change according to the season the clothes and dry-clean and bring the hidden danger of the health
After 11, a lot of may be tidying up the wardrobe, send the laundry to dry-clean the clothes changed according to the season summer, autumn. What is the composition that you know the clothes dry-clean pharmaceutical, as to the environment which kind of influence and will health be produced?
The high density dry cleaning solvent damages the nerve, liver, kidney, skin
Analyze from the sample investigation result, 85% of the laundries use four chlorine ethylene to dry-clean in the whole world, 90% of the laundries of our country use four chlorine ethylene.
Four chlorine ethylene is also called ethylene of the whole chlorine, it is colourless, there is liquid of a kind of smell of ether at room temperature. Mainly is used as the organic solvent, defat oil pharmaceutical, is used as the synthetic intermediate of chemical industry tooes industrially. Because four chlorine ethylene is apt to volatilize at room temperature, can absorb, enter the human body through respiratory tract, digestive tract and skin. Four chlorine ethylene of high density has part stimulating and anaesthesia function of central nervous system, can produce the liver, kidney to damage. The skin keeps in touch repeatedly, may cause dermatitis and eczema.
Foreign literature report, half the number fatal dose of four chlorine ethylene is 13 grams kilogram that the big mouse takes orally, the little mouse is 8.4 grams kilogram. The big mouse's respiratory tract lasts 5 weeks, can observe the fat of liver changes the sex to suck 1.35 grams one cubic meter of four chlorine ethylene. The big mouse's respiratory tract sucks 1.35 grams - 2.71 grams one cubic meter of four chlorine ethylene, 6 hours of every day, 5 days of every week, lasts 103 weeks, it is obvious renal tube cell tumour and monocytic leukemia morbidity increase.
Relevant research shows, the infant and pre-school children in development are extremely sensitive to four chlorine ethylene poisonous side effects; A research card of U.S.A. has really found four chlorine ethylene in person's milk. So, in terms of safe precaution, infant and pre-school children and enclosing the invasion that perinatal women should be far away from four chlorine ethylene as much as possible.
There are no ideal substitute products yet at present
Except bring the hidden danger to people's health, four chlorine ethylene can pollute the groundwater, destroy the atmospheric ozone layer. Germany, U.S.A. and Japan have generally investigated more than one hundred wells, has found the pollution of the groundwater of four chlorine ethylene. In U.S.A., four chlorine ethylene has already distributed one of the 5 kinds of most extensive pollutant as groundwater.
At present, have ideal products can substitute four the intersection of chlorine and ethylene yet, because relative toxicity its low and heat stability fine going the intersection of greasy dirt and the intersection of ability and better and recoverable characteristic that reuses, the dry-cleaning industry has already using for more than 60 years, the countries all over the world usually take and strengthen the way in which the clothes dry-clean the procedure to deal with their side effects.
Have not dry-cleaned the residual sanitary standard of four chlorine ethylene of the clothes yet both at home and abroad. Determine to four chlorine ethylene in the air in 30 domestic clothes laundries the result show, the clothes laundry is with the clear dreg (mao) The process is the tallest in density, secondly in order to fetch the clothing, throw the clothing and dry the process, four chlorine ethylene density reach several hundred milligrams cubic meter in some laundry air. Studies have suggested after clothes dry-clean, encapsulate with plastic bag, apt remaining more 4 chlorine ethylene. So consumers need to utilize the characteristic apt to volatilize of four chlorine ethylene, ventilate and dry in air, the dry-cleaning clothes fetched from the laundry wear, the clothes next to the skin, especially need paying attention to.
