TOP 1, poisonous land
The so-called toxic land refers to the land that once engaged in the production, storage and stacking of toxic and harmful substances, or caused soil, groundwater and air pollution and human health and ecological risks or hazards due to its migration and unexpected accidents. For example: chemical plants, infectious disease hospitals, pesticide plant, pharmaceutical factories, mines and smelters. According to media reports, a large number of toxic sites in China are being developed as residential land, many of which are "normally used" without treatment. Even some plots were photographed as land kings because of their superior geographical location. According to some data, Beijing Guangqumen 15 was originally a chemical plant. Auctioned in the market and became the king of Beijing in 2009. After renovation, a mansion was built. It is reported that the treatment of poisonous land in China is still in the backward stage of finding and treating one piece. Even more poisonous places are quietly threatening people's health even without the government's knowledge. And the harm of poisonous land to human body often takes ten years or decades to appear.
The most famous case in history is the Ralph Canal, which used to be an industrial waste yard in the United States. 1953 was covered by landfill and developed into a large number of houses and a school. Twenty-four years later, during the period of 1977, local residents frequently suffered from diseases such as abortion of pregnant women, premature death of children, infant malformation, epilepsy, rectal bleeding, etc., and only after investigation did the truth come out. This incident directly led to the establishment of the US government's "super reserve fund", which is the first time in history to use federal funds to clean up leaked chemicals and toxic garbage dumps.
Therefore, when we pay attention to a real estate project, past lives, that is, the project land, must do a good job of investigation.
TOP2, High Voltage Power Grid
According to authoritative experts' research, the diameter of high-voltage towers within the range of 1.6 km will have different degrees of influence on human body, especially on children and pregnant women! The proportion of deformed children is four times (compared with the proportion that does not live under high voltage). The impact within 300 meters is very serious, which will lead to the increase of cancer, leukemia and childhood leukemia several times. 1979, Wertheimer and Leeper of Sweden published for the first time that children living near power lines have a higher probability of leukemia than children living in other places, which led to extensive research on whether power frequency magnetic fields can cause cancer.
Tian Xiang, an expert published in Family Traditional Chinese Medicine, said that medical clinical practice shows that electromagnetic radiation generated by high-voltage transmission lines will cause insomnia, irritability, dizziness, rapid heartbeat and other symptoms to people in nearby houses, and even lead to neurasthenia, even cerebral infarction or cancer.
The problem of high voltage power grid has attracted the attention of domestic developers. Many projects with similar situations are also actively taking measures such as burying high-voltage lines or changing lines. However, in order to avoid unnecessary disputes after occupancy, it is necessary to clearly confirm the reconstruction plan and specific completion time recognized by relevant departments when buying a house.
TOP3, noise pollution
The noise pollution mentioned here refers to the situation that some projects are close to main roads, large supermarkets, office buildings, large stadiums and nearby airport stations. Noise has many effects on human health. Noise acts on people's central nervous system, making people's cerebral cortex excited and inhibited unbalanced, leading to abnormal conditioned reflex and damaging cerebrovascular tension.
These physiological changes can be recovered in the early stage, but they will lead to pathological changes over time, causing headaches, brain swelling, tinnitus, insomnia, memory loss, general fatigue and other symptoms. At night, projects adjacent to noise sources such as main roads will be more directly affected by noise pollution, which will seriously affect the rest of some owners. More seriously, living in such an environment for a long time will damage people's hearing and health. The greater the noise intensity, the higher the frequency, the longer the action time, the smaller the personal tolerance and the more serious the harm.
TOP4, light pollution
In recent years, similar light pollution reports have been frequently reported in major cities across the country. The main pollution sources are some giant electronic display screens, large light boxes, tall glass curtain wall buildings and commercial streets around or inside the project. Light pollution is a new type of environmental pollution that has not been fully recognized by people. Light pollution is everywhere and exists in various forms, which is harmful to organisms and their environment, as well as to human health. Common injuries are eyes and skin, followed by mental and nervous system, which can cause cardiovascular and cerebrovascular diseases in severe cases.
