Pollution's Impact: Nyc's Affected Organisms

New York City's air pollution is a significant environmental threat that affects the health of its residents. The dense population and low automobile dependence contribute to high levels of mass transit use, making New York one of the most energy-efficient cities in the United States. However, the concentration of pollution in certain areas, particularly in communities of colour, leads to a high incidence of asthma and other respiratory conditions. The Bronx, for example, has the highest rate of asthma-related emergency room admissions in the city and state.

The main sources of air pollution in New York City include vehicle traffic, industrial emissions, and power plants. Fossil fuel-powered cars, trucks, and buses emit harmful pollutants such as nitrogen dioxide and particulate matter. Additionally, industrial and construction activities release pollutants such as volatile organic compounds and particulate matter, which contribute to the formation of ground-level ozone, a respiratory irritant.

To address these issues, New York City has implemented regulations and policies to control emissions, such as the Clean Heat programme, and promoted the use of public transportation and bicycles. The introduction of electric buses and taxis has also helped reduce air pollution. Despite these efforts, air pollution in New York City remains a concern, particularly during the summer months when high temperatures and intense solar radiation increase the formation of ground-level ozone.

Ozone and PM2.5 cause about 2,400 deaths per year in NYC

Ozone and PM2.5 are two of the most harmful air pollutants in New York City. Ozone is a gas that forms when other pollutants in the air react with sunlight. It can cause coughing, throat irritation, and other serious respiratory problems. PM2.5, on the other hand, is a fine particulate matter that comes from sources such as smoke from fires, vehicle emissions, and industrial operations. These pollutants have serious health impacts on New Yorkers, particularly children, older adults, and people with pre-existing health conditions.

Health Impacts of Ozone and PM2.5

The health impacts of ozone and PM2.5 are far-reaching and affect a significant number of people in New York City. According to the New York City Department of Health and Mental Hygiene, ozone and PM2.5 cause about 2,400 deaths per year in the city and thousands more emergency department visits and hospitalizations for asthma, heart, and lung problems. The people most at risk from these pollutants include older adults, children, and individuals with pre-existing health conditions.

Ozone-Related Health Impacts

Ozone is a major respiratory irritant and can trigger coughing, throat irritation, and other serious respiratory problems. It is of particular concern during the summer months when warm weather and strong sunshine lead to higher levels of ground-level ozone. Children, people with lung diseases such as asthma, and even healthy adults who work or exercise outdoors are vulnerable to the effects of ground-level ozone.

PM2.5-Related Health Impacts

PM2.5, or fine particulate matter, can have serious health impacts, especially when exposure occurs over an extended period. It can worsen existing heart and lung diseases and contribute to more hospitalizations and emergency department visits. PM2.5 has also been linked to a shortening of life expectancy.

Reducing Ozone and PM2.5 Pollution

To reduce the health impacts of ozone and PM2.5, it is important to take measures to improve air quality. This includes reducing energy use at home and work, choosing cleaner forms of transportation, and supporting city initiatives to reduce pollution and promote energy conservation. Additionally, individuals can check air quality forecasts and limit time spent outdoors when air quality is poor.

Ozone and PM2.5 are significant contributors to the approximately 2,400 deaths that occur in New York City each year due to air pollution. These pollutants have far-reaching health impacts, particularly on vulnerable populations such as children, older adults, and people with pre-existing health conditions. By taking measures to improve air quality and reduce emissions, we can work towards creating a healthier environment for all New Yorkers.

Children and older adults are most at risk

Air pollution in NYC is a major environmental health problem, causing about 2,400 deaths per year, and thousands more emergency department visits and hospitalizations for asthma, heart and lung problems. Those most at risk include older adults, children, and people with pre-existing health conditions.

The lungs are negatively impacted by air pollution, and exposure over time can worsen serious health problems, including heart and lung diseases. This can lead to more hospitalizations and emergency department visits and shorten life expectancy.

Ozone, a component of smog, is more prevalent during the summer and can trigger coughing and throat irritation, leading to other serious respiratory problems. Children and people with lung diseases, such as asthma, are most vulnerable to ground-level ozone. It is also a risk for healthy adults who work or exercise outdoors.

Fine particulate matter, or PM2.5, is the most harmful urban air pollutant in NYC and is caused by smoke from fires, including building fires, wildfires, and even fireworks. Exposure to PM2.5 can worsen asthma, lung diseases, and heart conditions.

According to the NYC Department of Health and Mental Hygiene, the neighborhoods with the greatest levels of pollution-attributable hospital emergency department visits are all Environmental Justice (EJ) Neighborhoods. These neighborhoods have higher percentages of Black and/or Hispanic or Latino residents than NYC overall, and most are home to a majority of Black and Hispanic or Latino residents.

Additionally, communities of color are disproportionately exposed to emissions from heavy-duty diesel vehicles due to the location of arterial highways, commercial waste routes, and parking facilities for medium and heavy-duty fleets. These vehicles are major sources of nitrogen oxide and PM2.5 emissions in NYC.

The impact of air pollution on the health of children and older adults in NYC has been the subject of various epidemiological studies. One study found that exposure to various outdoor air pollutants, including particulate matter, ozone pollution, and nitrogen oxide, has significantly increased asthma, chronic obstructive pulmonary disease, lung cancer, and respiratory infections and illnesses in children and older adults.

Another study in NYC examined the effects of air pollution on the health of children and older adults in low-income communities and communities of color. It found that adverse health outcomes related to pollution were concentrated in these communities, partly due to exposure to airborne pollutants and higher baseline rates of health conditions, lower-quality housing, and less access to healthcare.

Overall, children and older adults are most at risk of the adverse health effects of air pollution in NYC, with communities of color and low-income communities bearing a disproportionate burden.

NYC has its own neighbourhood air quality monitoring network

New York City has its own neighbourhood air quality monitoring network, the New York City Community Air Survey (NYCCAS). The NYCCAS was established in 2008 and is the largest urban air monitoring programme in the United States. It collects air quality measurements of six pollutants: fine particulate matter (PM2.5), black carbon (BC), nitrogen dioxide (NO2) and nitric oxide (NO), which together are referred to as nitrogen oxides (NOx), wintertime sulfur dioxide (SO2), and summertime ozone (O3). Measurements are taken from 78 strategically chosen locations to ensure representative coverage across the city, as well as near high-emission locations such as Times Square and the Port Authority Bus Terminal.

The NYCCAS is operated by the Department of Health and Mental Hygiene (DOHMH) in close collaboration with Queens College of the City University of New York (CUNY). The programme was developed to help inform the city's sustainability plans, evaluate poor air quality exposure for health research, and educate the public about relevant topics such as changes in the sources of air pollution, city efforts to improve air quality, and related health impacts across NYC neighbourhoods.

The NYCCAS now has over 13 years of data at the neighbourhood level to track changes over time. Since the first year of monitoring in 2009, the NYCCAS has recorded steep decreases in annual average levels of all measured pollutants, except for O3, which largely results from emissions outside of the city. Annual average levels of PM2.5 have been reduced by 43%, NO2 by 39%, NO by 56%, and SO2 by 98%.

The NYCCAS data has helped drive targeted initiatives to improve air quality throughout the city. For example, neighbourhood-level PM2.5 data from NYCCAS was used in the selection of 200 schools for the Mayor's "Leading the Charge" plan—a $4 billion effort to electrify New York City schools and end the use of highly polluting No. 4 heating oil at all schools, starting with communities most impacted by air pollution-related health impacts.

High temperatures and solar radiation increase the formation of tropospheric ozone

Tropospheric, or ground-level, ozone is a harmful air pollutant that is particularly dangerous during hot, sunny weather. Ozone is a gas composed of three oxygen atoms, which can exist both in the Earth's upper atmosphere (the stratosphere) and at ground level (the troposphere). While stratospheric ozone is beneficial as it shields us from the sun's harmful ultraviolet rays, tropospheric ozone is a harmful air pollutant and the main ingredient in smog.

Tropospheric ozone is not directly emitted into the air but is formed by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOCs) in the presence of sunlight. These chemical reactions occur when pollutants from cars, power plants, industrial boilers, refineries, and other sources interact with solar radiation, particularly ultraviolet light. Therefore, high temperatures and solar radiation are key factors that increase the formation of tropospheric ozone.

During hot, sunny weather, the conditions are ideal for the production of ozone pollution. Ozone levels typically peak in the mid to late afternoon, after exhaust fumes from the morning rush hour have had time to react with sunlight. As the sun sets, the production of ozone begins to subside.

The formation of tropospheric ozone is of particular concern in urban areas, where high ozone levels usually occur during warm summer months. New York City (NYC), for example, has been taking steps to reduce emissions from local and regional sources, and its air quality has improved over the past few decades. However, air pollution, including ground-level ozone, still poses a severe hazard to the health of NYC residents.

Ground-level ozone can trigger a variety of health problems, especially for children, the elderly, and people with lung diseases such as asthma. In NYC, it is estimated that ozone and PM2.5 cause about 2,400 deaths per year and lead to thousands of emergency department visits and hospitalizations for respiratory, heart, and lung problems. Certain areas of NYC, known as Environmental Justice (EJ) Neighborhoods, experience higher levels of pollution and consequent health impacts. These EJ Neighborhoods are often communities of color and low-income areas, which face higher health risks due to historic disinvestment and limited access to healthcare.

To reduce the formation of tropospheric ozone and mitigate its health impacts, strategies should focus on cutting atmospheric pollution from cars, power plants, and other sources. Additionally, individuals can play a role by reducing energy use, choosing cleaner commutes, and limiting their time spent outdoors when air quality is poor.

The Bronx has the highest rate of asthma-related emergency room admissions in NYC

The Bronx has the highest rate of asthma-related emergency room admissions in New York City, a problem that is particularly prevalent among children. This is due in part to the borough's poor air quality, which is caused by several sources of pollution.

The Bronx's air pollution is largely a result of its proximity to major highways and industrial facilities, such as the Hunts Point Distribution Center and waste transfer stations. The high volume of truck traffic in the borough also contributes significantly to the poor air quality, as diesel trucks are a major source of nitrogen oxide and particulate matter emissions. In addition, The Bronx has a high poverty rate, with 26% of people living in poverty compared to 11% in the rest of the United States. This has led to subpar housing conditions, exposing residents to various environmental asthma triggers such as rodents, dust, mildew, and second-hand smoke.

The high rate of asthma in The Bronx has led to the creation of the Asthma-Free Bronx program, which aims to reduce asthma-related emergency room visits. The program provides personalized services to children who have been seen in the emergency department or hospitalized due to an asthma attack. It also helps coordinate key services between the hospital and other agencies, such as scheduling follow-up visits with primary care providers and referring children to education programs about asthma management.

The issue of air pollution in The Bronx is not unique, as other areas in New York City also struggle with poor air quality. However, the convergence of several polluting factors in The Bronx, as well as the high poverty rate, has made it particularly vulnerable to the negative health impacts of air pollution, including asthma.
