Preterm birth (PTB) rates (11.4% in 2013) in the United States (US) remain high and are a substantial cause of morbidity. Studies of prenatal exposure have associated particulate matter <2.5microns in diameter (PM2.5) and other ambient air pollutants with adverse birth outcomes, yet, to our knowledge, burden and costs of PM 2.5-attributable PTB have not been estimated in the US.

Electronic cigarettes (e-cigarettes) generate an aerosol by heating a solution (e-liquid) with a metallic coil. Whether metals are transferred from the coil to the aerosol is unknown.

Phthalates and bisphenol A (BPA) are widely used industrial chemicals that may adversely impact human health. Human exposure is ubiquitous and can occur through diet, including consumption of processed or packaged food.

Disparities in exposure to air pollution by race-ethnicity and by socioeconomic status have been documented in the United States, but the impacts of declining transportation-related air pollutant emissions on disparities in exposure have not been studied in detail.


Prior research has reported disparities in environmental exposures in the United States, but, to our knowledge, no nationwide studies have assessed inequality in noise pollution.

Green, natural environments may ameliorate adverse environmental exposures (e.g. air pollution, noise, and extreme heat), increase physical activity and social engagement, and lower stress.

The Florence Statement on Triclosan and Triclocarban documents a consensus of more than 200 scientists and medical professionals on the hazards of and lack of demonstrated benefit from common uses of triclosan and triclocarban. These chemicals may be used in thousands of personal care and consumer products as well as in building materials. Based on extensive peer-reviewed research, this statement concludes that triclosan and triclocarban are environmentally persistent endocrine disruptors that bioaccumulate in and are toxic to aquatic and other organisms. Evidence of other hazards to humans and ecosystems from triclosan and triclocarban is presented along with recommendations intended to prevent future harm from triclosan, triclocarban, and antimicrobial substances with similar properties and effects. Because antimicrobials can have unintended adverse health and environmental impacts, they should only be used when they provide an evidence-based health benefit. Greater transparency is needed in product formulations, and before an antimicrobial is incorporated into a product, the long-term health and ecological impacts should be evaluated.

There are over 7,000 e-cigarette flavors currently marketed. Flavoring chemicals gained notoriety in the early 2000’s when inhalation exposure of the flavoring chemical diacetyl was found to be associated with a disease that became known as “Popcorn Lung.” There has been limited research on flavoring chemicals in e-cigarettes.

Globally pollen allergy is a major public health problem, but a fundamental unknown is the likely impact of climate change. To our knowledge, this is the first study to quantify the consequences of climate change upon pollen allergy in humans.
