Frederica Perera (born 1941) is an American environmental health scientist and the founder of the Columbia Center for Children's Environmental Health at the Columbia University Mailman School of Public Health. [1] Her research career has focused on identifying and preventing harm to children from prenatal and early childhood exposure to environmental chemicals and pollutants. [2] She is internationally recognized for pioneering the field of molecular epidemiology, incorporating molecular techniques into epidemiological studies to measure biologic doses, preclinical responses and susceptibility to toxic exposure. [3]
Born in Boston, Massachusetts, Perera received her bachelor's degree in Liberal Arts from Harvard University/Radcliffe College in 1963. She received her DrPH in Environmental Health Sciences from Columbia University in 1976 and a PhD in Environmental and Social Policy from Columbia University in 1981.
In 1982, Perera joined the faculty of Columbia University Mailman School of Public Health in the Department of Environmental Health Sciences. In 1998, she founded the Columbia Center for Children's Environmental Health to conduct community-based research on environmental risks to childhood's health. [4]
Since the late 1980s, Perera has led studies applying molecular and imaging techniques within longitudinal cohort studies of pregnant women and their children in the U.S., Poland, and China, with the goal of identifying preventable environmental risk factors for developmental disorders, asthma, obesity, and cancer in childhood. [5] These exposures include toxic chemicals, pesticides, and air pollution, with particular focus on the adverse effects of prenatal and early childhood exposures. [6] This research has revealed that the prenatal period of development is especially vulnerable to toxic environmental exposures and that prenatal exposures such as air pollutants, chemicals in plastics, pesticides and flame retardants are linked to neurodevelopmental problems, obesity and/or asthma in childhood. [7] [8] [9] The research also found that stress and maternal hardship can increase the harm from chemical exposures. [10] The research has demonstrated the benefits of policies and other interventions to reduce or eliminate such exposures. [11] [12]
In 1982, Perera co-authored a seminal paper that defined the nascent field of molecular epidemiology, which uses biomarkers such as DNA adducts to understand the links between environmental exposures and disease with the goal of prevention—an approach she uses in her own research. [13] Perera was also among the first to report evidence that prenatal exposures to environmental toxicants result in adverse health outcomes in childhood and adolescence. [14] [15]
Perera has written extensively on the multiple threats to children's health and future well-being from fossil fuel combustion emissions, both from climate change and toxic air pollution, and the benefits of government action on health, the economy, and equity. [16]
Research findings by Perera and colleagues have been used to support, pass, and enforce laws that protect environmental and public health. Through a longstanding partnership with WE ACT for Environmental Justice, the center's findings have been used to influence policy in the areas of air pollution, asthma initiatives, secondhand smoke, residential pesticides, and chemical reform. [17]
Perera has received numerous honors, including the 20th Annual Heinz Award in the Environment for her lifetime achievement in research for the protection of children's health. [18] [19]
The Great Smog of London, or Great Smog of 1952, was a severe air pollution event that affected London, England, in December 1952. A period of unusually cold weather, combined with an anticyclone and windless conditions, collected airborne pollutants—mostly arising from the use of coal—to form a thick layer of smog over the city. It lasted from Friday 5 December to Tuesday 9 December 1952, then dispersed quickly when the weather changed.
Environmental health is the branch of public health concerned with all aspects of the natural and built environment affecting human health. To effectively control factors that may affect health, the requirements that must be met to create a healthy environment must be determined. The major sub-disciplines of environmental health are environmental science, toxicology, environmental epidemiology, and environmental and occupational medicine.
Phthalates, or phthalate esters, are esters of phthalic acid. They are mainly used as plasticizers, i.e., substances added to plastics to increase their flexibility, transparency, durability, and longevity. They are used primarily to soften polyvinyl chloride (PVC). Note that while phthalates are usually plasticizers, not all plasticizers are phthalates. The two terms are specific and unique and cannot be used interchangeably.
A polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings. The simplest representative is naphthalene, having two aromatic rings, and the three-ring compounds anthracene and phenanthrene. PAHs are uncharged, non-polar and planar. Many are colorless. Many of them are found in coal and in oil deposits, and are also produced by the incomplete combustion of organic matter—for example, in engines and incinerators or when biomass burns in forest fires.
Polybrominated diphenyl ethers or PBDEs, are a class of organobromine compounds that are used as flame retardants. Like other brominated flame retardants, PBDEs have been used in a wide array of products, including building materials, electronics, furnishings, motor vehicles, airplanes, plastics, polyurethane foams, and textiles. They are structurally akin to polychlorinated diphenyl ethers (PCDEs), polychlorinated biphenyls (PCBs) and other polyhalogenated compounds, consisting of two halogenated aromatic rings. PBDEs are classified according to the average number of bromine atoms in the molecule. The life-saving benefits of fire retardants led to their popularization. Standards for mass transit vehicles continues to increase as of 2021.
Chlorpyrifos (CPS), also known as chlorpyrifos ethyl, is an organophosphate pesticide that has been used on crops, and animals in buildings, and in other settings, to kill several pests, including insects and worms. It acts on the nervous systems of insects by inhibiting the acetylcholinesterase enzyme. Chlorpyrifos was patented in 1966 by Dow Chemical Company.
The National Institute of Environmental Health Sciences (NIEHS) conducts research into the effects of the environment on human disease, as one of the 27 institutes and centers of the National Institutes of Health (NIH). It is located in the Research Triangle Park in North Carolina, and is the only primary division of the NIH located outside of the Washington metropolitan area.
Environmental toxicants and fetal development is the impact of different toxic substances from the environment on the development of the fetus. This article deals with potential adverse effects of environmental toxicants on the prenatal development of both the embryo or fetus, as well as pregnancy complications. The human embryo or fetus is relatively susceptible to impact from adverse conditions within the mother's environment. Substandard fetal conditions often cause various degrees of developmental delays, both physical and mental, for the growing baby. Although some variables do occur as a result of genetic conditions pertaining to the father, a great many are directly brought about from environmental toxins that the mother is exposed to.
Dimethyl phthalate (DMP) is an organic compound and phthalate ester. it is a colourless and oily liquid that is soluble in organic solvents, but which is only poorly soluble in water.
WE ACT for Environmental Justice is a nonprofit environmental justice organization based in Harlem, Manhattan, New York City. The organization was founded in March 1988 to mobilize community opposition to the city's operation of the North River Sewage Treatment Plant, and the siting of the sixth bus depot in Northern Manhattan.
Air pollution is the contamination of air due to the presence of substances called pollutants in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. It is also the contamination of the indoor or outdoor environment either by chemical, physical, or biological agents that alters the natural features of the atmosphere. There are many different types of air pollutants, such as gases, particulates and biological molecules. Air pollution can cause diseases, allergies, and even death to humans; it can also cause harm to other living organisms such as animals and crops, and may damage the natural environment or built environment. Air pollution can be caused by both human activities and natural phenomena.
Air pollution is the introduction of chemicals, particulate matter, or biological materials into the atmosphere that cause harm or discomfort to humans or other living organisms, or damage ecosystems. Health problems attributed to air pollution include premature death, cancer, organ failure, infections, behavioral changes, and other diseases. These health effects are not equally distributed across the U.S. population; there are demographic disparities by race, ethnicity, socioeconomic status, and education. Air pollution can derive from natural sources, such as wildfires and volcanoes, or from anthropogenic sources. Anthropogenic air pollution has affected the United States since the beginning of the Industrial Revolution.
The health of a mother directly affects the fetus during pregnancy. High levels of vehicle pollution where pregnant women reside can have adverse health effects on fetuses.

Children are more vulnerable to the effects of climate change than adults. The World Health Organization estimated that 88% of the existing global burden of disease caused by climate change affects children under five years of age. A Lancet review on health and climate change lists children as the worst-affected category by climate change. Children under 14 are 44 percent more likely to die from environmental factors, and those in urban areas are disproportionately impacted by lower air quality and overcrowding.
