With the rapid pace of urbanization and the improvement of living standards, indoor environments have seen significant enhancements. However, excessive decoration has led to increased indoor air pollution, which remains a major threat to public health. It is now more urgent than ever to implement effective measures to control and reduce such pollution.
In one case, Mr. Zhang moved into a newly renovated luxury apartment in Longcheng, but soon after, he noticed that insects were being killed by the fumes inside. The air quality test conducted by Qingxiu District Quality Supervision Station revealed that formaldehyde levels were over six times higher than the national standard.
Similarly, Ms. Zeng’s family experienced symptoms like dizziness, memory loss, irritability, and sore throats after moving into their new home. A medical report suggested that indoor air pollution might be the cause. The monitoring results shocked them: not only was formaldehyde significantly above the limit, but benzene and TVOC (Total Volatile Organic Compounds) were also severelyè¶…æ ‡. This left Ms. Zeng in disbelief.
Data shows that indoor pollution from decoration can lead to serious health issues, including leukemia caused by substances like formaldehyde and benzene. These pollutants are often invisible but extremely dangerous.
The root cause of this problem lies in the use of substandard building materials. According to Qingxiu District Quality Supervision Station, over 330 new homes were tested, and it was found that formaldehyde, benzene, ammonia, and radioactive materials were the main sources of pollution. Materials like particleboard, furniture, wall paints, adhesives, wallpapers, and carpets release harmful substances that contribute to indoor air contamination.
Environmental pollution can cause brain hypoxia, nerve damage, dizziness, nausea, and even death in severe cases. Formaldehyde and benzene are particularly dangerous as they act as silent killers in indoor spaces, leading to chronic poisoning and long-term health effects, including impacts on the immune system, respiratory system, and even fetal development.
To tackle this issue, experts recommend stricter regulation of the construction material market, better enforcement of environmental testing, and the development of more effective pollution control methods. Consumers should also take proactive steps, such as using photocatalysts and ensuring that their home improvement contracts include clauses related to indoor air quality.
As winter, a peak season for renovations, approaches, it's essential for people to be aware of the complexity of indoor pollution sources. Before moving in, it’s wise to have the indoor environment tested by a professional agency. Only when the results meet national standards should residents feel confident about their new living space.
Aluminum single hung window is a relatively new type of window. Here is a detailed introduction about it:

Opening method: The window sash is opened and closed by pulling in the vertical direction. This opening method is different from traditional sliding windows or casement windows. It does not occupy the horizontal space indoors or outdoors and is particularly suitable for installation in locations with limited space, such as kitchens, bathrooms, narrow corridors, etc.
Advantages:
Good ventilation:Aluminum single hung windows can be opened to a large extent, so that indoor and outdoor air can circulate fully, effectively improving the indoor ventilation effect. In addition, some aluminum single hung windows can also realize multi-sash linkage to further increase the ventilation area.
Wide field of vision: Due to the particularity of its opening method, aluminum single hung windows will not be blocked by window frames like casement windows when opened, which can provide a wider field of vision and make the indoor space more transparent and bright.
High safety: When the window sash is closed, it fits tightly with the window frame, and with high-quality sealing strips, it can effectively prevent rain, dust, wind and sand from entering the room. At the same time, some aluminum single hung windows are also equipped with safety locks and other devices to enhance the anti-theft performance of the windows.
Easy to clean: The window sash can be tilted inward or outward, which is convenient for users to clean the inside and outside of the window, solving the problem of difficult cleaning of high-rise windows.
