Philip John Landrigan is a prominent American pediatrician and epidemiologist. A pediatrician is a doctor who specializes in the care of children. An epidemiologist is a scientist who studies how diseases and health issues spread through large groups of people. Landrigan has dedicated much of his career to public health advocacy. He focuses on protecting children from environmental hazards. These are substances in the air, water, or food that can cause harm. His work aims to identify and reduce exposure to dangerous materials.

Landrigan has focused extensively on the dangers of lead exposure. In the early 1970s, he conducted research near an ASARCO smelting plant in El Paso, Texas. A smelter is a factory that processes metal. He tested the blood of children attending nearby schools. He discovered that 60% of children living within one mile of the plant had elevated blood lead levels. Landrigan concluded that even small amounts of lead exposure can lower a child's IQ. In 2002, he linked childhood lead exposure to lifetime earning potential. He estimated that lead exposure in the United States causes an aggregate income loss of over $40 billion every year.

His scientific findings led to significant changes in government policy. Landrigan’s research played a key role in mandates to remove lead from the environment. The government began phasing out lead components from gasoline in 1975. A federal ban on lead paint followed in 1978. These changes had a massive impact on public health. By 2005, lead levels in American children had dropped by 88%. This shows how scientific evidence can lead to safer living conditions for entire populations.

Landrigan has also worked to protect children from pesticides. Pesticides are chemicals used to kill insects or other pests. In 1988, Senator Patrick Leahy of Vermont requested a five-year study. Landrigan led this study for the National Academy of Sciences. He wanted to see if safety standards for pesticides were adequate. At the time, standards were designed to protect a 150-pound adult. In 1993, his committee released a report called "Pesticides in the Diets of Infants and Children." The report showed that children are uniquely susceptible to the adverse effects of these chemicals. It recommended standards ten times more stringent than the ones used at that time.

Another area of his expertise involves the health impacts of asbestos. Asbestos is a mineral that can form tiny fibers. These fibers can be dangerous if inhaled. Following the destruction of the World Trade Center on September 11, 2001, Landrigan testified before the House Committee on Education and the Workforce. He addressed the presence of asbestos particles in the air. He noted that research shows smaller fibers can penetrate most deeply into the lungs. He argued that even low-level exposure in early childhood could have long-term consequences. This work highlighted the importance of monitoring air quality after major disasters.

Landrigan's academic and professional journey is extensive. He graduated from Boston Latin School in 1959 and Boston College in 1963. He earned his medical degree from Harvard Medical School in 1967. He also completed an internship at Cleveland Metropolitan General Hospital and a residency at Boston Children's Hospital. He earned a Master of Science in Occupational Medicine from the University of London with distinction. Throughout his career, he held many leadership roles. He was the Director of the Children's Environmental Health Center at Mount Sinai Medical Center. In 2018, he became the founding director of Boston College's Global Public Health Program.

He has also served the military through the United States Naval Reserve. From 1996 to 2005, he served in the Medical Corps and retired as a Captain. He has received many honors for his service and research. These include the Meritorious Service Medal from the U.S. Public Health Service. He also received the Child Health Champion Award from the U.S. Environmental Protection Agency. The World Health Organization noted that his work was instrumental in passing the Food Quality Protection Act of 1996. Landrigan has published over 500 scientific papers to help advance the field of global health.
