PVC tiles and linoleum are dangerous for asthmatics

02.11.2013

Children who sleep in a room with PVC flooring are more likely to develop asthma than children who do not have the material in their rooms. In addition, there is speculation that PVC covering in the parents' bedroom also provokes the development of asthma in unborn children, which indicates exposure to PVC during the prenatal period.

Soft polyvinyl chloride (PVC) is a common material - it is linoleum and PVC tiles that imitate various materials, including natural wood. Outwardly, such material looks attractive, and it is unpretentious in care, which made it very popular among consumers.

But Swedish researchers aren't thrilled about PVC flooring. They believe soft PVC contains phthalates, which are commonly released into the environment. Chemicals from the phthalates group, according to scientists, can provoke endocrine disorders that affect the development of several chronic diseases, such as asthma and allergies.

Swedish scientists conducted a multi-year experiment to determine how PVC coating affects the development of asthma and related disorders. The study began in 2000 and involved more than 14 children aged 000-1 years (at the start of the experiment).

The basic questionnaire contained questions about family health, lifestyle, characteristics of the house or apartment, etc. The scientists conducted control surveys in 2005 and 2010, that is, they traced the dynamics of the development of diseases. The researchers paid the greatest interest in the further study to children who developed asthma and other allergic diseases during the observation period.

The analysis showed that children who had PVC flooring in their bedrooms were more likely to develop asthma - asthma was usually diagnosed by doctors in the first 10 years of life. The incidence of asthma among children who did not have PVC flooring in their bedrooms was much less common. According to scientists, in some cases, the risk of developing allergies and asthma more than doubled.

Scientists have also found evidence that PVC floors in parents' bedrooms also contribute to the development of asthma in unborn children. According to the researchers, this is a sign that the PVC coating affects the baby in the womb.

This study is not the only one that speaks about the unsafety of PVC, more precisely, the phthalates emitted by it. Thus, a previous study showed that PVC materials in the house are dangerous for children aged 2-6 months - phthalates (butylbenzyl phthalate, BBzP) accumulate in their bodies. Scientists point out that people themselves can reduce the risk of developing asthma and allergies in their children, simply by abandoning the PVC coating.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Samsung Wireless: 1,5TB wireless storage, hotspot, offline charging 14.05.2014

Seagate has announced that its Samsung HDD division has begun shipping a new Samsung Wireless device to the market. This drive is aimed primarily at mobile users. And its main feature is the Wi-Fi hotspot function, which allows you to connect up to five users.

Samsung Wireless is positioned as a portable accessory for smartphones and tablets. The novelty has a compact form factor and low weight. You can access the data on the drive wirelessly. Moreover, such streaming file transfer is configured quickly and easily. The manufacturer explains the relevance of his device by the fact that the built-in memory of modern mobile devices is often limited and does not allow you to carry a collection of movies in HD quality.

The capacity of Samsung Wireless reaches 1,5 TB. Supported operating systems include Anroid 2.3 and above, Windows 8, 7, Vista, XP SP2, Ma OS X 10.6 and above. Built-in battery provides up to seven hours of continuous operation.

The device can connect to wireless networks and provide Internet distribution. The USB 3.0 port allows you to use your Samsung Wireless as a portable battery to recharge your mobile devices. In addition, it can be used to connect the HDD directly to the computer without using Wi-Fi.

The recommended retail price of new items in the world market is $179.
