A groundbreaking study has revealed that exposure to phthalates chemicals commonly used to make plastics flexible may have played a major role in over 356,000 cardiovascular-related deaths globally in 2018. The research, conducted by a team at New York University’s Grossman School of Medicine, places a spotlight on a widespread environmental health hazard linked to one of the world’s leading causes of death. According to the study, nearly 13.5% of cardiovascular deaths in individuals aged 55–64 were attributable to di-2-ethylhexyl phthalate (DEHP) exposure. DEHP is a specific type of phthalate widely found in household items such as food containers, PVC products, and even medical equipment. The study’s findings align with earlier research that connected phthalates to around 50,000 premature deaths annually among older Americans many of them resulting from heart-related conditions.

The burden of phthalate-related deaths is not evenly distributed. The study showed that 75% of global deaths linked to DEHP exposure occurred in the Middle East, South Asia, East Asia, and the Pacific regions, highlighting a strong correlation between these chemicals and industrial development. Among all countries, India recorded the highest number of phthalate-related deaths in 2018, accounting for 103,587 deaths a figure driven by the country’s fast-expanding plastics industry and widespread use of DEHP-laden materials in consumer goods. Lead author Sara Hyman, associate research scientist at NYU Grossman School of Medicine, emphasized the gravity of the situation:
“By highlighting the connection between phthalates and a leading cause of death across the world, our findings add to the vast body of evidence that these chemicals present a tremendous danger to human health.”

Dr. Leonardo Trasande, director of the NYU Center for the Investigation of Environmental Hazards, added further context:
“What we know at present is that multiple chemicals used in plastic materials contribute to inflammation, hack our hormones—our natural signalling molecules that underlie basic biological functions including metabolism and cardiovascular function.” He further stressed that this study fits into a much broader body of evidence, including laboratory, animal, and human studies, all pointing toward a direct link between these chemicals and heart disease.

Phthalates are a group of chemical compounds primarily used to increase the flexibility and durability of plastics. They’re found in a vast range of household and industrial products, from food packaging and children’s toys to personal care items like lotions, shampoos, and perfumes. Because of their ubiquity, scientists often refer to them as “everywhere chemicals.” Though widely used, phthalates have been the subject of growing scientific concern. They belong to a class of compounds known as endocrine disruptors, which interfere with the body’s hormone systems. This interference can cause significant health problems ranging from cardiovascular disease and obesity to reproductive and developmental issues.

Exposure to phthalates has been linked to:

• Increased risk of heart attacks and strokes

• Obesity and metabolic disorders

• Attention Deficit Hyperactivity Disorder (ADHD)

• Reproductive health issues including low sperm count and hormonal imbalances

• Pregnancy complications and adverse birth outcomes

Despite widespread documentation of their risks, phthalates continue to be used globally, with regulation varying greatly by country. While some nations have taken steps to restrict phthalate use in products like toys or food packaging, large-scale global exposure remains a pressing public health issue.

The findings of the NYU study urge immediate attention from public health officials and regulators. The link between environmental chemicals like DEHP and serious health consequences calls for stricter global standards on plastic production and usage, particularly in developing regions with high exposure levels. In nations like India, where the plastics sector is booming and consumer goods are heavily reliant on flexible plastics, public awareness and regulatory reform could play critical roles in reducing preventable health risks.

Moreover, the study highlights the importance of monitoring chemical exposure as part of cardiovascular risk assessments, particularly for older adults. Healthcare professionals may soon need to consider environmental factors like phthalate exposure alongside traditional risk factors like cholesterol and blood pressure. This latest research reinforces the growing chorus of experts demanding safer chemical practices, enhanced regulatory oversight, and better-informed consumers. As the world continues to grapple with plastic pollution and its far-reaching consequences, recognizing the invisible threat of phthalates is a vital step toward creating a healthier, safer future.
