Marilyn Howarth, MD
PHILADELPHIA— Marilyn Howarth, MD, an adjunct associate professor of Emergency Medicine and Systems Pharmacology and Translational Therapeutics in the Perelman School of Medicine at the University of Pennsylvania, has been honored by the community organization Chester Environmental Partnership for her longstanding involvement with its efforts to protect the environment and safeguard the health of members of the Chester community.
Howarth, who is director of community outreach and engagement at Penn’s Center of Excellence in Environmental Toxicology (CEET), was honored along with four others at the Partnership’s annual awards dinner last month for their commitment to environmental stewardship.
CEET works to determine how harmful environmental exposure can lead to disease. Understanding these processes is crucial for early diagnosis, intervention, and prevention strategies. Penn CEET is one of 17 federally designated Environmental Health Science Core Centers in the United States.
Chester has a number of environmental problems stemming from numerous current and abandoned industrial sites, two major chemical manufacturers, municipal and infectious medical-waste treatment facilities, a trash-to-steam incinerator, and heavy automobile and truck traffic. The city has a 64-percent higher rate of ovarian cancer, a 24-percent higher rate of lung cancer, and three times the rate of asthma than the rest of Pennsylvania, according to statistics from the Southeastern Pennsylvania Household Health Survey.
Among the activities Howarth was recognized for providing environmental health expertise on a range of health and environmental justice issues to the Partnership, meeting with industry and regulatory agencies on setting permit standards for emissions, and working with medical providers on advising patients on how to avoid exposures to toxicants. She also emphasizes the importance of social factors such as poverty, crime, and housing quality in affecting health. For example, she has counseled residents that home maintenance problems such as dust and moisture can cause or aggravate asthma. In these efforts Howarth focuses on the concept of the exposome: the total environmental exposures of a lifetime and how they cumulatively affect individual and community health.
As a physician-researcher Howarth has extensive experience evaluating and treating patients with exposure to heavy metals, solvents, mold, and respiratory allergens and irritants. She is a founding professor of Penn’s Master in Public Health environmental and occupational-health track and provides educational sessions on environmental health topics to community and employee groups. She joined the Penn faculty in 1995. Howarth earned her medical degree from the Robert Wood Johnson School of Medicine and her undergraduate degree in biology from Swarthmore College.
