Avoid These Air Pollution Mistakes In Mexico

Mexico City has been notorious for its poor air quality for decades, with the United Nations declaring it the most polluted city in the world in 1992. While air quality has improved significantly since then, it still has a long way to go. This paragraph will discuss the actions that have not yielded the desired results in tackling air pollution in Mexico.

Avoid indoor air pollution: don't cook with solid fuels like wood, use improved stoves with chimneys

Mexico City was once labelled the world's most polluted city by the United Nations in 1992. While air pollution has significantly improved since then, it is still a major issue. The Mexican government has implemented policies to combat air pollution, but the effectiveness of these policies has been questioned.

One way to reduce air pollution in Mexico is to avoid indoor air pollution by not cooking with solid fuels like wood. Solid fuels, such as wood, crop residues, agricultural waste, and dried animal dung, emit substantial amounts of toxic pollutants when burned in simple cooking stoves. These pollutants can cause eye and throat irritation and are a major risk factor for lung cancer, cardiovascular disease, and respiratory disease. Women and young children, who spend more time indoors, are especially vulnerable to the effects of indoor air pollution.

To reduce indoor air pollution, improved stoves with chimneys can be used. Chimneys help to lower peak levels of indoor pollution and reduce exposure to smoke. However, it is important to note that chimneys do not intrinsically reduce emissions, but rather move them to the surrounding household and village environment. Additionally, chimneys require regular maintenance and proper use to function correctly.

Low-emission biomass stoves with features such as secondary combustion, insulated combustion chambers, and fans can also help to improve combustion efficiency and lower emissions. While not all "improved" biomass stoves meet World Health Organization (WHO) guidelines, they can still serve as an important transitional technology. It is also recommended to install ventilation, such as chimneys or hoods, to reduce smoke exposure indoors. However, smoke that is vented outdoors can re-enter the home and contribute to outdoor air pollution, so it is best to pair ventilation with cleaner fuels and low-emission stoves.

It is important for individuals to transition to clean household energy and stop using polluting fuels and devices. Clean energy devices should be designed with the user in mind to facilitate household use. Behavior changes, such as opening windows and doors while cooking or cooking outside, can also help reduce exposure to harmful air pollutants.

Avoid outdoor air: stay inside when air quality is poor, especially if you have lung issues

Mexico City has long struggled with air pollution. In 1992, the United Nations declared it the most polluted city in the world. The situation has improved since then, but the city still ranks 48th for air pollution out of 98 cities.

Air pollution in Mexico City is caused by industrial growth, a sharp increase in population, and the proliferation of vehicles. The topography of the city also does not help, as it is located in a basin where air pollutants tend to be trapped.

To protect yourself from the harmful effects of air pollution, it is advisable to stay inside when air quality is poor, especially if you have lung issues. On days when the air quality is poor, the Mexican government may issue environmental risk alerts, urging people to stay indoors. Schools may be closed, and citizens are recommended to stay home until the levels decrease.

You can monitor the air quality in Mexico City through the IMECA index, which measures the level of pollution and the risk it poses to human health. When the index falls between 101 and 150, the air quality is considered "poor," and some contaminants could have moderate health effects, especially for those with high sensitivity to contaminants.

Additionally, the Mexican government has implemented policies such as "Hoy No Circula," which restricts vehicles from circulating on certain days of the week based on their emissions performance. By staying informed about such policies and following the government's recommendations, you can better protect yourself from the harmful effects of air pollution.

Avoid driving: don't use a car, instead walk, cycle, or use public transport

Mexico City has long been infamous for its poor air quality, with the UN declaring it the world's most polluted city in 1992. The city's high altitude, industrialisation, and proliferation of vehicles have all contributed to this issue. To tackle this problem, it is essential to reduce emissions from transportation, which is currently the main source of air pollution in the city centre.

One effective strategy is to avoid driving and using private cars. Instead, opt for walking or cycling, which are forms of active transport that do not produce emissions. Mexico City has recognised the importance of this approach and has invested in building bike lanes and expanding bicycle accessibility. This not only improves air quality but also promotes a healthier lifestyle for the population.

Public transportation offers another viable alternative to using private cars. The Mexican government has acknowledged this by investing significant sums in public transport, aiming to prioritise electric transport options. This includes the expansion of public transportation options and the creation of incentives for purchasing cleaner vehicles. By encouraging the use of public transport, the number of vehicles on the road can be reduced, leading to lower emissions and improved air quality.

The "Hoy No Circula" policy, introduced in 1989, is a notable example of the government's efforts. This policy requires all vehicles in Mexico City and the state of Mexico to undergo emissions testing every six months. Based on their performance, vehicles are assigned a verification label, with underperforming vehicles prohibited from being driven one weekday per week and two Saturdays per month. While the effectiveness of this policy has been questioned, it demonstrates the government's commitment to reducing vehicle emissions.

By implementing these measures and encouraging citizens to avoid driving private cars, Mexico is taking important steps towards improving air quality and creating a healthier and more sustainable environment for its population.

Avoid open fires: don't burn firewood, charcoal, or other solid fuels

Mexico City has long been infamous for its poor air quality, having been named the world's most polluted city by the United Nations back in 1992. While the city has since dropped to 917th place in global rankings, air pollution remains a pressing issue.

One of the key contributors to air pollution in Mexico is the burning of organic matter, including forest fires, firewood, and other solid fuels. In May 2019, the Mexican government declared an "extraordinary atmospheric environmental contingency," citing the excessive levels of harmful particles in the air, largely caused by a series of fires in regions near the capital.

To address this issue, it is imperative to avoid open fires and refrain from burning firewood, charcoal, or other solid fuels. Here are some specific measures to consider:

• Opt for alternative sources of cooking fuel: Instead of relying on solid fuels like firewood or charcoal for cooking, consider switching to cleaner alternatives such as gas or electric stoves. These options produce fewer toxic emissions, especially when used with proper ventilation.
• Practice fire safety: While it may be tempting to start a bonfire or use charcoal grills for outdoor activities, these practices can contribute to air pollution. Be mindful of local fire safety guidelines and avoid open burning whenever possible.
• Support reforestation and fire prevention initiatives: Get involved with local organisations or volunteer groups that focus on reforestation and fire prevention efforts. By supporting the restoration and protection of green spaces, you can help reduce the impact of wildfires and promote sustainable ecological practices.
• Advocate for policy changes: Join or support campaigns that push for stricter regulations on the use of solid fuels and open burning. Encourage the government to implement and enforce environmental health standards that align with the guidelines set by the World Health Organization (WHO).
• Promote public awareness: Educate others about the harmful effects of burning solid fuels and the alternatives available. Community engagement and collective action are crucial in fostering a cultural shift towards more sustainable and environmentally friendly practices.

By taking these proactive steps, individuals can play a significant role in reducing air pollution caused by open fires and the burning of firewood, charcoal, and other solid fuels in Mexico.

Avoid industrial areas: don't live near factories or industrial processes that emit pollutants

Mexico has the second-largest economy in Latin America, and industry plays a significant role in the country's GDP. In 2022, 65% of Mexico's industrial space construction was concentrated in just four cities: Mexico City (20%), Monterrey (19%), Ciudad Juarez (16%), and Tijuana (10%). These cities are major industrial hubs, with Monterrey known as the country's industrial capital, contributing about 23% of its GDP.

However, industrialization has had a significant impact on the environment and air quality in these cities. Mexico City, in particular, has been a concern for health officials for decades due to its poor air quality. The city's high altitude of 7382 feet above sea level causes its oxygen levels to be 25% lower, and carbon-based fuels do not combust completely, leading to increased pollution. The rapid industrialization and urbanisation of Mexico City in the 20th century, coupled with a population boom, have resulted in severely poor air quality. In 1992, the United Nations even labelled Mexico City as the world's most polluted city.

To combat air pollution, the Mexican government has implemented various policies and taken several actions. They required the reformulation of gasoline, closed or moved polluting factories, and prohibited driving one day per week. The government has also invested in public transportation and expanded bicycle accessibility. These efforts have shown results, as Mexico City is no longer the most polluted city in the world, dropping to 917th place in 2021 according to IQAir.

However, air pollution remains a concern, and it is essential to take precautionary measures. When visiting or living in Mexico, it is advisable to avoid industrial areas and not live near factories or industrial processes that emit pollutants. The Northern Industrial Corridor, comprising states such as Baja California, Nuevo León, Chihuahua, Sonora, Tamaulipas, Coahuila, and Durango, is a vital part of the supply chains for sectors like construction, mining, aerospace, and automotive. While these areas are essential for the country's economy, they may have higher levels of air pollution due to industrial activities.

Therefore, if you are concerned about air quality and its potential impact on your health, it is best to choose residential areas away from these industrial zones. Additionally, staying informed about air quality indices and following local guidelines during periods of high pollution can help minimise the negative effects of air pollution on your health.
