Home environmental standards

1. What is home improvement in environmental protection?
Eco-friendly home improvement is the decoration after the indicator of indoor air formaldehyde, benzene and total ** volatile organic compounds (TVOC) content in line with or better than State regulations, such as the various environmental testing standards.
2. the decoration ring standard did they?
Environmental protection standards. The Ministry of construction promulgated the code for indoor environmental pollution control of civil building engineering (GB50325-2001), the State administration of quality supervision, inspection and quarantine issued the standards of indoor decorating and refurbishing materials-limitations of harmful substances.
3. called "decoration pollution" what does it mean?
Indoor decorating and refurbishing materials distributed harmful toxic pollutants, pollution of indoor environment. The pollution of indoor pollution from the decoration itself is called home improvement. If renovated high levels of pollutants in the indoor air, and long unsolved, **** body discomfort, affect health.
4. decoration pollution the most harmful substances is?
According to the construction, decoration and furniture material usage, indoor home pollutants mainly include the following categories:
Formaldehyde
BTex: benzene, toluene, xylene
** Total volatile organic compounds (TVOC)
Fat-free toluene diisocyanate (TDI)
** Soluble lead, cadmium, mercury, arsenic and other heavy metals
5. interior decoration pollution mainly comes from what material?
Formaldehyde is mainly from man-made materials, adhesives and coatings.
Benzene comes mainly from paint thinner, waterproof paint, latex, and so on.
(TVOC) total main ** volatile organic compounds from paints, latex paints, and so on.
(TDI) toluene diisocyanate resin comes mainly from polyurethane coating.
Heavy metal pollution mainly comes from painting, adhesives and other materials.
6. home pollutants are the root cause of disease?
Home pollutants inside the newly renovated housing, higher if exceed national standards, and was not resolved for a long time, will affect human health, and can lead to disease.
However, experts pointed out that there is still no scientific evidence shows that certain diseases are caused by indoor air pollution. Therefore, prevention of air pollution, more important than ex-post accountability and more effective.
7. What are the hazards of formaldehyde pollution?
Formaldehyde is a colourless, soluble irritant gases. Inhalation can cause liver and lung function, immune system decline, formaldehyde or by the International Agency for research on cancer (IARC 1995) identified as a suspected carcinogen.
8. the benzene pollution is what?
Benzene (including benzene, toluene, xylene) is a colorless gas with a special aroma. Absorption through the skin contact and cause poisoning, can cause drowsiness, headache and vomiting. Benzene is recognized by the International Agency for research on cancer as a toxic and carcinogenic substances.
9. the TVOC pollution is what?
(TVOC) total volatile organic compounds are room temperature, the gas of various volatile organic compounds collectively. Main gas composition are alkanes, aromatics and alkenes, alkyl halide, esters, aldehydes, etc. Irritation of the eyes and respiratory tract, can hurt the liver, kidney, brain and nervous system.
10.TDI toluene diisocyanate pollution hazard what?
(TDI) toluene diisocyanate, lipids are organic compounds with strong pungent odour, have a strong stimulus to the skin, eyes and respiratory tract, chronic exposure to TDI or inhalation of high concentrations may cause bronchitis, asthma, pneumonia, pulmonary edema.
11. What is the damage of heavy metal pollution?
Soluble heavy metals including lead, cadmium, mercury, arsenic, etc. Long-term exposure can cause contact dermatitis or Eczema of the skin. Nerves, organs systems can cause hazard to the human body, particularly significant impact on child development.
12. you mentioned false concept of environmental protection, environmental protection is the matter?
False concept of environmental protection and environmental protection which was a fraud in the marketplace, the consumer and the quality of their products seriously irresponsible. Many companies are launched home decoration environmental protection, but in order to do a real home environment, starting with only the most basic materials, strict control to ensure all materials meet the national environmental indicators (or higher environmental standards), are the fundamental way to solve the problem.
13. the false concept of environmental protection, environmental protection: is there any difference?
False green, communications used in a variety of ways to prove their use of environmentally friendly materials, but in practice does not use eco-friendly materials and uses only a few eco-friendly materials and, worse, using a fake environmentally friendly materials. BACK
