Long Beach Air Pollution: Causes And Concerns

Long Beach, California, has been dubbed Asthma Alley due to its poor air quality, which is said to be the worst in the United States. The city's air pollution is caused by a combination of factors, including vehicular emissions, low rainfall, and its proximity to two of the country's largest seaports. The high levels of nitrogen dioxide, sulfur dioxide, ozone, and particulate matter in the air contribute to respiratory issues, particularly for sensitive groups such as children and individuals with asthma.

Vehicular pollution

Nitrogen dioxide (NO2), a major pollutant emitted from vehicle engines, is of particular concern. NO2 is released in large quantities from car and truck engines and contributes to the formation of ground-level ozone, a harmful pollutant that can cause respiratory issues and damage lung tissue.

The impact of vehicular pollution on Long Beach's air quality is exacerbated by the city's geographical location. Sitting between two of the largest seaports in the country, Long Beach experiences additional pollution from ship emissions, including sulfur dioxide (SO2) released from ship fuels due to differences in fuel regulations. The combination of vehicular and ship emissions creates a challenging environment for residents, particularly those living in areas like "Asthma Alley," close to Interstate 710.

To address vehicular pollution in Long Beach, it is crucial to implement measures that reduce emissions from vehicles. This can include promoting public transportation, electric vehicles, and active transportation options like walking and biking. Strict emission standards and regular vehicle maintenance checks can also help lower pollution levels. Additionally, creating green spaces and urban forests can mitigate the effects of pollution by absorbing and filtering harmful particles.

Overall, the high levels of vehicular pollution in Long Beach have significant impacts on the health and well-being of its residents. By taking steps to reduce emissions and improve air quality, the city can create a healthier and more sustainable environment for its community.

Nitrogen dioxide from vehicle engines

Nitrogen dioxide is a significant contributor to air pollution in Long Beach, California. The city, which is situated between the two largest seaports in the country, has been dubbed "Asthma Alley," and ranks among the worst in the U.S. for air quality. Vehicular pollution is a primary concern, with exhaust fumes from tens of thousands of cars and motorcycles on the road at any given time contributing to the poor air quality.

Nitrogen dioxide (NO2) is released in large quantities from vehicle engines, particularly those of older, less fuel-efficient models. This pollutant is a major irritant to the eyes, nose, and respiratory system, and can aggravate heart and lung diseases over time. People living in areas with poor air quality, such as Long Beach, are advised to avoid outdoor activities during rush hours and to exercise away from heavily trafficked roads.

The impact of nitrogen dioxide from vehicle engines on Long Beach's air quality is exacerbated by the region's weather patterns. From about March through October, there is little rainfall, allowing emissions to accumulate in the atmosphere and be baked by the abundant sunlight, forming harmful ground-level ozone (O3) or smog. This combination of factors results in elevated levels of nitrogen dioxide and other pollutants, adversely affecting the health of residents, particularly those with respiratory conditions such as asthma.

To address the issue of nitrogen dioxide pollution from vehicle engines, Long Beach and surrounding areas may need to implement measures to reduce vehicle emissions. This could include promoting public transportation, electric vehicles, or other alternative forms of transportation, as well as implementing stricter emissions standards and regulations for vehicles. Additionally, increasing awareness about the impact of vehicle emissions on air quality can empower individuals to make more informed choices and take actions to reduce their contribution to nitrogen dioxide pollution.

In summary, nitrogen dioxide from vehicle engines is a significant contributor to Long Beach's air pollution problem, leading to adverse health effects on residents. Addressing this issue will likely require a combination of policy changes, infrastructure improvements, and community education to reduce vehicle emissions and improve overall air quality in the area.

Sulphur dioxide from ship fumes

Sulphur dioxide (SO2) is a health-damaging air pollutant that is released in large quantities in the fumes from ships due to the high sulphur content of marine fuel. The sulphur content of marine fuel is much higher than the levels permitted on land, and this contributes to between 19,000 and 91,000 premature deaths each year in coastal regions.

In Long Beach, California, the air quality is generally good, but there are times when the air pollution is high enough to be unhealthy for sensitive groups, who may experience symptoms such as difficulty breathing or throat irritation. While data on the specific causes of air pollution in Long Beach is limited, sulphur dioxide from ship fumes is likely a contributing factor. As a busy port city, Long Beach is likely to be exposed to significant ship fumes, which are a major source of sulphur dioxide.

The International Maritime Organization (IMO) has introduced regulations to reduce the sulphur content of marine fuels, which has successfully lowered global SO2 emissions. The new rules, implemented in 2020, decreased the maximum percentage of sulphur allowed in marine fuel from 3.5% to 0.5% for all ships worldwide. This followed an earlier, more limited restriction that was in place between 2010 and 2015, which only applied to ships operating around the coasts of North America and the North Sea.

While the shift to low-sulphur shipping fuel has had positive health impacts, it has also had an unintended consequence on global warming. Sulphur particles in ship exhaust fumes have been counteracting some of the warming effects of greenhouse gases. By reducing the sulphur content of marine fuel, this masking effect has been weakened, leading to a potential boost in global warming. Some researchers have proposed that the drop in SO2 emissions due to the IMO's clean air regulations could be a factor in the recent spike in global sea surface temperatures.

Low rainfall

Long Beach, California, has been dubbed "Asthma Alley" due to its poor air quality. The city has good air quality for just 10% of the year, and in 2019, it was ranked last in air quality out of the 100 largest cities in the U.S. One of the main causes of this is low rainfall.

Vehicular pollution is a significant contributor to the poor air quality in Long Beach. With a large population and many commuters, there are substantial amounts of exhaust fumes released from cars and motorbikes. Nitrogen dioxide, a common vehicle emission, is a major pollutant that can cause inflammation of the respiratory tract and damage lung tissue.

The city's proximity to two of the country's largest seaports also impacts air quality. Ship fumes contain high levels of sulfur dioxide due to the larger amounts of sulfur in ship fuels. This pollutant further contributes to respiratory issues and can cause lung damage.

The combination of low rainfall and high emissions from vehicles and ships creates a challenging environment for residents of Long Beach, particularly those with respiratory conditions such as asthma.

Proximity to seaports

Long Beach, California, has been dubbed "Asthma Alley" due to its poor air quality, which is caused by a combination of factors, including its proximity to seaports. The city is located between the two largest seaports in the country, which contributes significantly to the air pollution in the area.

The use of fossil fuels by ships, such as those in the seaports near Long Beach, releases a large amount of sulfur dioxide into the atmosphere. This is due to the larger amounts of sulfur often found in ship fuels, which can vary in composition and quality due to differing fuel regulations. Sulfur dioxide is a major contributor to acid rain and can cause inflammation of the respiratory tract and damage to lung tissue.

In addition to sulfur dioxide, ships also emit nitrogen oxides (NOx), which are another class of air pollutants. These compounds are formed during the combustion of fossil fuels and can be released into the atmosphere as a result of ship engine exhaust. Nitrogen oxides play a significant role in the formation of ground-level ozone, a harmful pollutant and component of smog. Ground-level ozone is formed when NOx is exposed to solar radiation, which is abundant in Long Beach, and it can irritate the eyes, nose, and respiratory system.

The impact of seaport emissions on air quality in Long Beach is further exacerbated by the lack of rainfall in the region. From March through October, there is little to no rainfall to flush or purge the atmosphere of accumulated emissions. As a result, these emissions remain in the air and are baked by the sunlight, contributing to the formation of harmful pollutants.

The poor air quality in Long Beach, influenced by seaport emissions, has significant health implications for its residents. The high levels of pollutants can aggravate respiratory conditions, such as asthma, and increase the risk of heart and lung disease. It is advised that people living in areas with poor air quality, like Long Beach, minimise their outdoor activities during rush hours and exercise caution when in close proximity to major roadways.
