Green Design: Xxl City Pollution Solution

While decoration can cause indoor pollution, such as from formaldehyde and benzene in wood-based panels, glue, paint, and leather, trees can help combat air and ground pollution in cities. Trees filter pollutants, absorb carbon dioxide, and release oxygen into the atmosphere, helping to cool homes. They also block noise pollution and increase land value. However, in video games like Cities: Skylines, trees are reported to be purely decorative, while in SimCity, they are said to have a positive impact on the environment.

Interior decoration can cause indoor air pollution, which is harmful to health

Interior decoration can contribute to indoor air pollution, which poses a serious threat to human health. While it is important to note that the game Cities: Skylines primarily focuses on outdoor pollution, it is worth discussing the impact of indoor air pollution caused by interior decoration in real-world scenarios.

Indoor air pollution caused by interior decoration processes has become a growing concern. As people prioritize their physical health and the quality of the air they breathe, reducing air pollution during renovation or remodelling becomes essential. According to statistics, approximately 2.8 million people die each year due to decoration pollution, either directly or indirectly. This issue has been recognized as one of the five most harmful environmental problems globally.

The materials used in interior decoration can significantly impact indoor air quality. For instance, Radon, which is released from stone, Formaldehyde, which is commonly found in floorboards and other plate-based products, and Benzene, which comes from paint and glue, can all contribute to indoor air pollution. These substances can release gases that persist in the air for extended periods. When their concentrations exceed safe levels, they can adversely affect physical health. Formaldehyde, for example, is a colorless, flammable gas with a strong odor that can irritate the skin, eyes, nose, and throat. Prolonged exposure to high levels of Formaldehyde may even lead to certain types of cancers.

The impact of indoor air pollution is particularly concerning given that humans spend a significant proportion of their time indoors, whether at home or in office spaces. This prolonged exposure to polluted indoor air can directly harm individuals, especially children, pregnant women, and seniors, who tend to spend more time indoors. Additionally, poor indoor air quality can cause or contribute to infections, lung cancer, and chronic lung diseases such as asthma.

To mitigate the harmful effects of indoor air pollution caused by interior decoration, it is crucial to prioritize the use of non-toxic materials and proper ventilation during and after the decoration process. By raising awareness of this issue and implementing measures to improve indoor air quality, we can create healthier living and working environments while still enjoying the aesthetic benefits of interior decoration.

Poisonous decoration materials can release over 300 kinds of VOCs and cause 30+ diseases

Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. They include a wide variety of chemicals, some of which are toxic and can have adverse health effects. These compounds are emitted by thousands of products, including many household items such as paints, varnishes, waxes, cleaning products, disinfectants, cosmetics, and fuels. The concentrations of VOCs are often significantly higher indoors than outdoors, and they can be released during use or storage.

The health effects of VOCs vary, and some people may experience immediate symptoms such as eye, nose, and throat irritation, headaches, nausea, dizziness, and difficulty breathing. Long-term exposure to VOCs can lead to more severe issues, including potential damage to the liver, kidneys, and central nervous system. Some VOCs are also linked to cancer in both animals and humans. People with respiratory conditions, children, the elderly, and those sensitive to chemicals may be more vulnerable to the impacts of VOCs.

Poisonous decoration materials are a source of VOCs and can release over 300 kinds of these compounds. These toxic compounds can off-gas into the indoor air, affecting the quality of the air we breathe. The specific health effects depend on the type of VOC and the level and duration of exposure. Some common symptoms associated with exposure to VOCs in decoration materials include irritation to the eyes, nose, and throat, as well as headaches, nausea, dizziness, and respiratory issues.

To reduce exposure to VOCs from decoration materials, it is important to increase ventilation during and after the use of such products. Following manufacturer instructions, disposing of unused products, and choosing low-VOC options are also recommended. Additionally, individuals should be cautious when using products containing VOCs, especially those with respiratory conditions or chemical sensitivities.

While the exact number of diseases caused by VOCs from decoration materials may vary, it is clear that these compounds can lead to a wide range of health issues, including short-term irritation and long-term organ damage. Therefore, it is crucial to take precautionary measures to minimize exposure and prioritize the use of safer alternatives whenever possible.

PAEs, used in plasticizers, are significant indoor pollutants, especially in China

While playing the simulation game Cities: Skylines, players often struggle with managing pollution levels. The game reflects real-world challenges, such as the issue of indoor pollutants, specifically phthalic acid esters (PAEs), in China. PAEs are organic chemicals commonly used in consumer products and various industrial and medical applications. They are widely employed as plasticizers to enhance the flexibility of polyvinyl chloride (PVC) resins and other polymers.

PAEs, used in plasticizers, have been identified as significant indoor pollutants, particularly in China. PAEs are semi-volatile organic compounds (SVOCs) that can adversely affect human health. They are known to be harmful to the endocrine, reproductive, and respiratory systems. In China, PAEs account for 90% of the plasticizer usage in PVC production, and the country also has the highest production and consumption quantities of plasticizers globally.

Studies have been conducted in various Chinese cities, such as Hangzhou and Tianjin, to assess the pollution levels and characteristics of PAEs in indoor and outdoor environments. The results showed that PAEs were more prevalent in indoor sites, with higher concentrations in newly decorated residences, ordinary residences, and offices compared to outdoor air. The industrial sites exhibited the highest PAE values, and the concentrations were higher in winter than in spring and summer.

The excessive use of PAEs has raised concerns about their potential health and environmental impacts. They can be easily dispersed during the manufacturing, storage, use, and disposal of plastic materials. It is important to determine the concentrations and sources of PAEs in fine particles, as they can be inhaled and pose risks to human health.

While the game Cities: Skylines does not directly address the issue of PAEs, it highlights the importance of managing pollution levels. Players can implement strategies such as separating industrial zones from residential areas and utilizing road decorations and highway sound barriers to minimize noise pollution. These measures can help create healthier and more sustainable virtual cities, reflecting real-world challenges and potential solutions.

Outdoor air pollution in cities is a major health problem

Air pollution is a mix of hazardous substances from both human-made and natural sources. Natural sources of air pollution include smoke from wildfires, ash and gases from volcanic eruptions, and gases such as methane. In cities, air pollution is caused by residential energy use for cooking and heating, vehicles, power generation, agriculture/waste incineration, and industry.

The health impacts of outdoor air pollution are well-established. Exposure to fine particulate matter, such as sulfates, nitrates, ammonia, sodium chloride, black carbon, mineral dust, and water, can cause oxidative stress and inflammation in human cells, which may lead to chronic diseases and cancer. Short-term exposure to higher levels of outdoor air pollution is associated with reduced lung function, asthma, cardiac problems, emergency department visits, and hospital admissions. The International Agency for Research on Cancer of the World Health Organization (WHO) has classified air pollution as a human carcinogen.

The WHO has developed guidelines and interventions to address outdoor air pollution and protect public health. The WHO Global Air Quality Guidelines (AQG) provide thresholds and limits for key air pollutants that pose health risks, as well as interim targets to promote a gradual shift to lower concentrations. The organization also promotes initiatives for healthy sectoral policies, including energy, transport, housing, urban development, and electrification of healthcare facilities.

To reduce exposure to outdoor air pollution, the National Institute of Environmental Health Sciences (NIEHS) supports community-engaged research and citizen science. NIEHS grant recipients have developed community-level tactics and public policies, such as using high-efficiency particulate air (HEPA) filtration, building land-use buffers, improving urban design with green spaces, and creating active travel options like bicycling and walking paths. Additionally, noise pollution, which is even more inevitable than regular pollution, can be mitigated by using road decorations and highway sound barriers, keeping residential zones away from central routes, and separating industrial zones from residential areas.

Trees can help combat ground pollution

Trees are a natural remedy to combat ground pollution. They act as the earth's purification system by absorbing toxic chemicals and releasing oxygen. Trees absorb harmful toxins through their stomata or 'pores', filtering the air and reducing pollution levels. This process also helps to mitigate the greenhouse gas effect by trapping heat and reducing ground-level ozone.

Trees play a crucial role in protecting people from the harmful effects of air pollution, which is a global crisis. According to the World Health Organization, nine out of ten people breathe polluted air, leading to approximately seven million deaths annually. Air pollution increases the risk of strokes, lung cancer, heart disease, and immune system damage. It also contributes to environmental damage, causing global warming and acid rain, which further harms trees and ecosystems.

By absorbing pollutants, trees help reduce the impact of air pollution on human health. They protect against respiratory disorders, asthma, allergies, and skin problems. Trees also improve the surrounding land, creating a healthier and more appealing environment for people to live in. Additionally, trees can help reduce power consumption by absorbing carbon dioxide from vehicle emissions, thereby reducing the need for energy used for transportation.

While trees cannot stop air pollution at its source, they are effective in minimising its effects. Computer simulations have shown that trees and forests in the contiguous United States removed 17.4 million tonnes of air pollution in 2010, with corresponding health benefits valued at 6.8 billion dollars. This pollution removal improved air quality, prevented mortalities, and reduced acute respiratory symptoms.

In conclusion, trees are a vital natural solution to combat ground pollution. They absorb toxins, release oxygen, and provide numerous health and environmental benefits. To effectively address ground pollution, it is essential to preserve existing forests and plant more trees, especially in areas affected by high levels of air pollution.
