Researchers at Washington University in St. Louis published a paper late last year that found carcinogens present in the air of the St. Louis metropolitan area to be highly concentrated in Black and poor neighborhoods. They found that approximately 14% of the census tracks in the city had elevated cancer risk due to exposure to toxic chemicals in the air and that these air toxic hots spots were independently associated with neighborhoods with high levels of poverty and unemployment, and low levels of education. Census tracks with the highest levels of both racial isolation of Blacks and economic isolation of poverty were more likely to be located in air toxic hot spots than those with low combined racial and economic isolation.
This paper is important because the authors used an innovative geospatial approach developed by other researchers to identify spatial patterns of residential segregation in their study area. This approach captures the degree of segregation at the neighborhood level and identifies patterns of isolation of different metrics, which in this study was black isolation and poverty isolation. This approach differs from tradition methods that looked at the percentage of blacks or poverty in a neighborhood.
The authors used these two segregation measures – Black isolation and poverty isolation – to identify neighborhoods segregated by race and income in the St. Louis metropolitan area and evaluated the risks of exposure to carcinogens in the air in these areas. The cancer risk data came from the Environmental Protection Agency’s National Air Toxics Assessment and the census track sociodemographic data came from the American Community Survey. All spatial analyses were conducted using Arc GIS software.
These researchers found that census track levels of poverty, undereducation and unemployment were associated with toxic hot spots, while factors such as per capita income and median household income were inversely associated with toxic hot spots. These findings support other studies that identified disparities in exposures to ambient air emissions of toxic chemicals and that raised questions about whether residential segregation leads to differential exposure to air pollutants.
While the authors discuss a number of possible pathways connecting segregation and health, the relationship between segregation and exposure to air toxics is unclear. They discuss various factors that result in segregation leading to the “cycle of segregation” that includes neighborhoods with low social capital, few community resources and low property values which tends to attract more low income and minority residents and exposures to unhealthy air toxics.
The authors concluded that this study provides strong evidence of the unequal distribution of carcinogenic air toxics in the St Louis metropolitan area and that residential segregation leads to differential exposure to chemicals in the air that cause cancer.

As movements for racial and environmental justice escalate across the US, these struggles – which, as groups like the National Black Environmental Justice Network point out, must be seen as one – have a common foe: the fossil fuel industry. The same companies that drive environmental racism in Black and Brown communities through toxic and climate-changing pollution also fund police power in cities that stretch from Houston and Detroit to New Orleans and Salt Lake City.

Last week marked the 75th anniversary of the two bombings that changed the course of the world, Hiroshima and Nagasaki. Not only did these two bombings obliterate the populations of two Japanese cities, but they also still impose lasting health effects on those residents.
Thousands of people died in both Hiroshima and Nagasaki following the explosions. These immediate deaths were due to the explosion, the fires that followed, and radiation poisoning. Although many people did immediately die from exposure to radiation, there were many survivors of the explosions who faced the health consequences of radiation later in life. A major consequence of this radiation is the mutation and damage of genes, which therefore leads to cancer. For bomb survivors, the risk of cancer, specifically Leukemia, was shown to be 46%. This type of cancer typically appeared a couple years after the bombings. The United States government obviously understood the immediate civilian casualties that would occur from dropping the bombs but did not take into account the suffering and death that would continue decades later.
Similarly, the U.S. also failed to acknowledge the lasting health effects of other chemicals used during wartimes. Specifically, the use of Agent Orange in Vietnam is still poisoning people today. Both U.S. and Vietnamese military forces together used more than 20.2 million gallons of herbicides to destroy trees as a military tactic. These herbicides, and specifically Agent Orange, contain dioxins. Dioxins are a highly toxic group of chemicals that, among other health effects, can cause cancer. U.S. Veterans of Vietnam are still suffering from the effects of Agent Orange and are being compensated for their health issues. On the other hand, Vietnamese citizens who are battling similar consequences have not been awarded the same considerations.
Today, chemical companies in the U.S. are still disregarding human health in the manufacturing, use, and disposal of various chemicals. Many communities are suffering from health complications due to toxins in their air, water, and soil. In order to avoid the lasting health consequences of toxic chemicals, the government must do more to protect residents of these communities. Specifically, the government needs to provide more regulation on industries to avoid long-lasting health complications in sacrifice zones. In addition to this, the government should compensate communities that already have faced these adverse health effects, just as was done for Vietnam Veterans.

Children are oftentimes more vulnerable to the negative effects of environmental injustice. This is because their bodies have not been fully developed to face the harsh health impacts from their environment. Nonetheless, according to the National Vital Statistics Reports done by the CDC, in 2018, infants of a black mother were more than twice as likely to die compared to infants of a white, Asian, or Hispanic mother. This is an issue raised by inequality that has always been around, and yet does not receive enough attention.
There are many reasons that lead to this infant mortality gap based on race. For example, access to health care, access to adequate food, and other socioeconomic factors create differences in children’s health. Most importantly, however, the environment in which the child grows up in plays the greatest role in affecting the child’s health. Environmental injustice is the most significant factor that affects this infant mortality rate gap.
The major causes of infant mortality in the US include asthma, birth defects, neurodevelopmental disorders, and preterm birth. These illnesses are all effects of the surrounding environment, either directly affecting the child or indirectly through the mother.
Families with lower socioeconomic status tend to be disproportionately exposed to areas with more serious air pollution. Thus, children growing up in these communities have a higher chance of getting asthma. Specifically, even among adults, asthma rates are higher in blacks than in whites. This is a clear case of environmental injustice that leads to the infant mortality rate gap.
Besides asthma, the other causes of infant mortality can also be attributed to environmental injustice. Communities with higher exposures to toxic chemicals lead to more infant mortality deaths. Mothers exposed to toxic chemicals may face health effects, thereby causing birth defects leading to infant mortality. At the same time, infants directly exposed to these toxic chemicals face a greater consequence as their immune system have not been fully developed. Families with lower socioeconomic status tend to reside in these communities with higher exposures to toxic chemicals, thereby causing the infant mortality rate gap.
Many of the causes of infant mortality are created by the environment, and environmental injustice plays a huge role in affecting specific communities with lower socioeconomic status. Thus, there is a large racial gap of infant mortality rates as children’s health are more likely to be affected by the negative effects, such as air pollution and toxic chemicals. This issue requires more attention in order for the inequality to be eliminated completely. As a result of environmental injustice, many infant lives are lost without the chance to enjoy their full life.
