Air Pollution In The Bronx: Uncovering The Root Causes

The Bronx, particularly the South Bronx, is one of the most culturally vibrant communities in New York City. However, it is also one of the most polluted areas in the city, with residents suffering from a range of illnesses, including asthma, heart disease, and diabetes. The South Bronx is circled by highways and dotted with truck depots, waste transfer stations, power plants, and landfills, which emit harmful pollutants and attract polluting diesel trucks. The constant presence of diesel trucks and the lack of green spaces in the community contribute to the high levels of air pollution, which disproportionately affect low-income people of color.

Diesel trucks and other vehicles

The Bronx, particularly the South Bronx, has some of the worst air pollution in New York City. The area is dotted with truck depots, waste transfer stations, and power plants, making it a dumping ground for pollution. Diesel trucks and other vehicles are a significant contributor to this issue.

Diesel trucks are attracted to the South Bronx due to the presence of warehouses, waste transfer stations, and power plants. These facilities create a high demand for diesel trucks, which emit harmful pollutants such as nitrogen dioxide and fine particulate matter. Nitrogen dioxide is a key traffic-related air pollutant that contributes to 21,000 new cases of childhood asthma every year in the New York metro region. The thousands of trucks that pass through the South Bronx each day pollute the air and contribute to the development of chronic health conditions such as asthma, heart disease, and diabetes.

The South Bronx has some of the highest childhood asthma rates in the country. While air pollution exposure is not the only factor, research indicates that more childhood asthma cases in the South Bronx are attributable to traffic-related air pollution than elsewhere in the city. The lack of tree cover and green space in the area also makes the South Bronx hotter than other parts of the city, and extreme heat can worsen air pollution and trigger asthma attacks. Living near truck traffic is a major public health concern in the South Bronx, and experts have warned that children who attend school close to major roads are at an increased risk of developing serious health conditions.

The pollution from diesel trucks and other vehicles has detrimental effects on the health of residents, most of whom are low-income people of color. The area has been nicknamed "Asthma Alley", and residents suffer from a range of illnesses due to toxic air exposure. The air quality in the Bronx can reach unhealthy levels, particularly for sensitive groups who may experience symptoms such as difficulty breathing and throat irritation.

Efforts to address this issue include a research project by South Bronx Unite and environmental health scientists from Columbia Mailman School of Public Health. They plan to install 25 air pollution monitors in strategic locations throughout the neighborhoods of Mott Haven and Port Morris to better understand the sources of pollution and work towards clearing the air. Additionally, New York State's cumulative impacts law, S8830, aims to prevent the approval and re-issuing of permits for actions that would increase inequitable pollution burdens on disadvantaged communities.

Power plants and warehouses

The South Bronx has been targeted by industries that emit harmful chemicals into the air, including power plants and warehouses. The area is also a dumping ground for pollution, with circled highways and dotted truck depots, waste transfer stations, and landfills. These facilities attract thousands of polluting diesel trucks that emit harmful pollutants, such as nitrogen dioxide and fine particulate matter, which contribute to the development of chronic health conditions like asthma, heart disease, and diabetes.

Power plants, in particular, have been identified as a major source of air pollution in the South Bronx. The area has four waterfront "peaker" power plants installed in the early 2000s as a temporary solution for short-term periods of high energy demand. Today, these power plants are used regularly and have become a permanent fixture in the community.

Warehouses, such as the Fresh Direct warehouse, have also been identified as significant contributors to air pollution in the South Bronx. The constant traffic of diesel trucks coming in and out of these warehouses spews exhaust and emits harmful pollutants into the air. The South Bronx has some of the highest childhood asthma rates in the country, and research indicates that more than 30% of these cases are attributable to traffic-related air pollution.

The lack of tree cover and green space in the community also makes the South Bronx hotter than other parts of the city, and extreme heat can worsen air quality and trigger asthma attacks. The residents of the South Bronx, mostly low-income people of color, are suffering from a range of illnesses due to toxic air.

To address these issues, South Bronx Unite, an environmental justice group, is working to improve local air quality monitoring and create tools to tell the stories found in monitoring data. They have also installed air pollution monitors in strategic locations throughout the neighborhoods to track particle pollution and gases that cause health issues. Additionally, New York State lawmakers introduced the Clean Deliveries Act, which aims to review the negative impacts of "mega-warehouses" and establish emissions reduction plans.

Lack of green spaces

The South Bronx has a significant lack of green spaces, which has contributed to the air pollution problem in the area. The neighbourhood is crowded with industries, such as waste transfer stations, warehouses, power plants, and printing presses, which attract thousands of diesel trucks that emit harmful pollutants. The constant presence of these trucks on the streets of the South Bronx is a major source of air pollution and has led to the area having some of the highest childhood asthma rates in the country.

The lack of green spaces and tree cover in the South Bronx has exacerbated the air pollution problem. Trees help to absorb and reduce harmful emissions, and their absence contributes to the neighbourhood being hotter than other parts of New York City. This extreme heat can worsen air quality and trigger asthma attacks, especially in children, pregnant people, seniors, and those with existing respiratory and cardiovascular conditions. The South Bronx's position, surrounded by highways, further contributes to the high levels of air pollution in the area.

The local community has recognised the impact of the lack of green spaces on air quality and health outcomes. Organisations such as Nos Quedamos in Melrose maintain green spaces to help residents with asthma, providing a place of relief where pollutants are absorbed by trees and plants rather than lingering in the air. Local council member Diana Ayala has also prioritised funding for redesigning the Lozada Playground to include more trees, acknowledging their importance in reducing emissions.

The South Bronx Unite, an environmental justice group, is actively working to address the air pollution crisis in the South Bronx. They have launched an air quality monitoring project, installing 25 air pollution monitors in strategic locations throughout the neighbourhoods of Mott Haven and Port Morris. This project aims to gather data on particle pollution and gases that cause health issues, empowering the community with real-time air quality information.

The lack of green spaces in the South Bronx is a critical issue that contributes to the area's air pollution problem and negatively impacts the health and well-being of residents. Addressing this issue, through initiatives such as increasing tree cover and creating more green spaces, is essential for improving air quality and the overall health of the community.

Industrial sites and construction

The Bronx, particularly the South Bronx, has some of the worst air pollution in New York City. The area is burdened by a large number of pollution-emitting trucks, power plants, waste transfer stations, and warehouses. These industrial sites contribute to the high levels of air pollution in the area, leading to negative health outcomes for residents.

Industrial sites, such as power plants and waste transfer stations, emit harmful pollutants into the air, including nitrogen dioxide and fine particulate matter. These pollutants have been linked to the development of chronic health conditions in residents, including asthma, heart disease, and diabetes. The South Bronx, in particular, has some of the highest childhood asthma rates in the country, with an estimated 20% of cases attributed to pollution, and this figure is likely even higher in communities with the most traffic-related air pollution.

The concentration of industrial sites in the Bronx contributes to the high levels of air pollution in the area. Waste transfer stations, for example, attract a large number of diesel trucks that emit pollutants as they rumble through the community. The constant presence of these trucks is not an accident; the South Bronx, like other low-income areas and communities of color, has been targeted by industries that emit harmful chemicals.

In addition to the negative health impacts, the industrial sites and construction in the Bronx also affect the quality of life for residents. The lack of green space and tree cover in the area, partly due to the prevalence of industrial sites, makes the South Bronx hotter than other parts of the city. Extreme heat can worsen air quality and trigger asthma attacks, further exacerbating the health issues associated with air pollution.

The high levels of air pollution in the Bronx, largely due to industrial sites and construction, have not gone unnoticed by the community. Local activists and scientists are working together to address this issue. Efforts include installing air pollution monitors to gather data and expose pollution sources, as well as advocating for policies like New York State's cumulative impacts law, designed to prevent the approval of actions that would increase inequitable pollution burdens on disadvantaged communities.

Nitrogen dioxide and other pollutants

Nitrogen dioxide (NO2) is a key traffic-related air pollutant in the Bronx, contributing to 21,000 new cases of childhood asthma every year in the New York metro region. It is formed by combustion, which damages lung tissue, causes breathing problems, and contributes to smog and acid rain. The Bronx is circled by highways and dotted with truck depots, waste transfer stations, and power plants, which attract polluting diesel trucks. These trucks emit harmful pollutants like nitrogen dioxide and fine particulate matter, contributing to the development of chronic health conditions like asthma, heart disease, and diabetes.

Road traffic is the principal outdoor source of nitrogen dioxide, and the combustion of fossil fuels, such as diesel, is a significant contributor to this. The South Bronx, in particular, has some of the highest childhood asthma rates in the country, and research indicates that more cases of childhood asthma in the area are attributable to traffic-related air pollution than elsewhere in New York City. The lack of tree cover and green space in the community also makes the South Bronx hotter than other parts of the city, and extreme heat can worsen air pollution and trigger asthma attacks.

In addition to nitrogen dioxide, other pollutants in the Bronx include particulate matter, carbon monoxide (CO), ozone (O3), formaldehyde, and benzene. These pollutants are linked to unwanted health outcomes, including respiratory and cardiovascular diseases. Formaldehyde, for example, is a known carcinogen that can cause irritation to the eyes and lungs and increase the risk of asthma. Benzene, resulting from motor vehicle and industrial emissions, is another known carcinogen that can harm bone marrow and red blood cell function.

To address the poor air quality in the Bronx, South Bronx Unite has launched an air quality monitoring project, installing 25 air pollution monitors in strategic locations throughout the neighbourhoods of Mott Haven and Port Morris. This data will help push for policies that promote clean air and empower the community with real-time air quality information.
