The hottest xylene catches up with formaldehyde an

  • Detail

Xylene "catching up" with formaldehyde has become a new pollution of Shenyang home decoration

the over standard rate of formaldehyde and benzene has a downward trend, while toluene and xylene have an upward trend due to the large application of wood coatings and wall paint wallpaper

instead of cabinets at home, solid wood furniture is used. Instead of ceiling, wallpapers of various styles are posted in the living room

originally thought that such decoration could reduce formaldehyde pollution, but Ms. sun, a citizen, did not expect that her physiological disorder was related to the solid wood furniture in her home, because the furniture contained excessive toluene

learned a set of data released by the indoor air testing center of Shenyang Environmental Monitoring Center. The data showed that among 230 newly decorated households in Shenyang, 51 households had toluene exceeding the standard, 74 households had xylene exceeding the standard, and exceeded formaldehyde for the first time

after living in her new house, she often had headaches

in early 2011, Ms. sun, a citizen, bought a new house. It is said that the more man-made board materials are used, the more serious indoor formaldehyde pollution will be, and the "decoration smell" will not evaporate. At the suggestion of her friends, Ms. sun didn't decorate the closet and partition in the traditional way, but spent more than 30000 yuan in the market to buy some solid wood furniture, even the ceiling was saved, and wallpaper of different styles was posted in the room

after the decoration, Ms. sun moved in as soon as she could smell the house in the future. Due to the cold weather, the air circulation was also very poor. After check-in, Ms. sun often had headaches and couldn't sleep. The monthly super accurate physiological period didn't come, and her body began to dry, desquamate and even itch, causing dermatitis

this situation lasted for half a year. Ms. sun found a professional department to carry out indoor air detection. Only then did she know that toluene and xylene in her home exceeded the standard by more than ten times. The hospital examination results also showed that Ms. sun's symptoms did not rule out chronic toluene poisoning caused by home decoration

in Ms. sun's house, the inspectors found that the chemical reagents of her wallpaper glue, bright paint on solid wood furniture, tapestries and other decorations contain high toluene

the rate of toluene and xylene exceeding the standard increased

according to a set of data released by the indoor environmental monitoring center of Shenyang Environmental Monitoring Center, from 2011 to 2012, in the environmental testing of more than 230 households and indoor public places, 35 households exceeded the standard of formaldehyde; 51 households exceeded the standard for toluene, with an increase of 4.73% compared with 2010; Xylene exceeded the standard in 74 households, an increase of 8.11%

it is noted that from the perspective of the average value and over standard rate of major indoor air pollutants in Shenyang, formaldehyde and benzene show a downward trend, while toluene and xylene show an upward trend. The exceeding standard rate of xylene also exceeded that of formaldehyde for the first time. In 2011, the overall exceeding standard rate of air pollutants in Shenyang indoor operation convenience accounted for 44.3%

wall paint and wallpaper are widely used

why does toluene and xylene "catch up" with formaldehyde

environmental protection experts said that according to the current situation, the general public's concept of decoration has changed, most people began to favor solid wood furniture, and the consumption of artificial boards has decreased. At the same time, with the extensive application of wood coatings and wall paint wall vacuum insulation board, which not only has high tightening strength, but also paper decorative materials, toluene and xylene gradually "catch up" with formaldehyde and become a new home decoration pollution

in addition, formaldehyde has a strong irritant taste, and citizens are very sensitive to its harm. Toluene is relatively cheap, and most manufacturers are optimistic about toluene, a low-cost additive, which makes toluene and xylene become the main indoor air pollutants, followed by formaldehyde and benzene

with the arrival of spring, many citizens move to new houses. The temperature in northern spring gradually rises, the indoor environment is dry, and the temperature changes greatly, and the indoor ventilation is less. The residual pollutants after decoration will volatilize with the increase of temperature. This indoor condition catalyzes the generation and accumulation of residual pollutants in indoor decoration (such as formaldehyde, benzene, toluene, xylene, etc.)

environmental protection experts said that the current situation of indoor air quality in Shenyang is not optimistic, and the cases of immune system, respiratory system and blood system diseases indirectly caused by indoor environmental pollution are increasing year by year. If exposed for a long time, these main polluting gases will cause varying degrees of harm to the human body, especially to infants, pregnant women, the elderly and other vulnerable groups with weak physique and low resistance, and the harm caused is irreparable

symptoms of exposure to polluted gases include these formaldehyde: dizziness, insomnia, fatigue, memory loss, abdominal pain, nausea, vomiting, chest tightness, asthma, etc., which can cause nasopharyngeal carcinoma, high-pressure lung cancer, skin cancer, leukemia, colon cancer, etc. Benzene: headache, pale complexion, decreased vision, red and swollen skin, dryness, etc. Toluene: eye conjunctiva and pharynx congestion, limb weakness, convulsions, coma, hepatomegaly, dry skin, abnormal menstruation. Xylene: irritating to eyes and upper respiratory tract, neurasthenia, dermatitis, blurred consciousness, etc

eight suggestions for home decoration

■ when purchasing furniture, let the merchants provide formal and qualified test reports. If conditions permit, it is best to let the furniture be placed under ventilated conditions for a longer period of time before use

■ family decoration should be simplified as far as possible. Look at Shandong with national new materials

■ if the decoration time is more than one year and there is no obvious odor in the room, the biodegradation method can be selected. For example, cultivating aloe, Cymbidium, Chlorophytum, green pineapple and other plants at home, and opening windows for ventilation for one to two hours a day when weather conditions permit, can effectively volatilize indoor pollutants

■ ensure the ventilation rate and lighting rate of the room

■ pay attention to the construction quality to prevent unreasonable construction procedures or construction processes from affecting the normal volatilization and diffusion of pollutants and causing indoor environmental pollution

■ when living, if you obviously feel that there is a peculiar smell in the room and are accompanied by adverse reactions (tears in the eyes, poor breathing, red and swollen skin, etc.), after the indoor air detection by the authoritative department, the values exceed the standard, you can choose a professional indoor environmental management company for treatment

■ choose decorative materials with superior environmental protection indicators, and pay attention to asking for test reports from manufacturers or sellers

■ strictly check the decoration acceptance. 2~4 weeks after the decoration, please have a professionally qualified testing organization test the indoor environment. If the test results exceed the standard, corresponding treatment measures can be taken, and check in after passing the standard
