Ubiquitous phthalates are common chemicals humans encounter through multiple daily exposure routes
In short: A review of environmental data found that phthalates, or phthalic acid esters, are nearly universal in the environment due to their widespread use in plastics and consumer goods. Because people spend the majority of their time indoors, these chemicals are highly concentrated in indoor air. The study highlights that humans may ingest or inhale up to 70 μg/kg/day of these substances through food, water, dust, and skin contact.
The research synthesizes existing literature to show how phthalates move through air, water, soil, and sewage systems. They are known to act as endocrine disruptors, affecting reproductive health in various fish and mammal species, while also impacting broader ecosystem functions.
This review compiles data from many different environmental matrices to assess global contamination. However, as a synthesis of existing literature, it does not provide new primary data from original experiments.
Why it matters: Understanding how common chemicals like phthalates move through our environment is key to assessing their impact on human and ecosystem health.
