Published in the journal Environmental Pollution, this study measured 24 types of phenols, such as butylparaben and 4-nonylphenol, in urine samples collected from over 3,500 pregnant women during their first trimester. The researchers tracked the health of the women’s children up to the age of four, revealing that high exposure to butylparaben increased the likelihood of asthma development, while low exposure to 4-nonylphenol posed additional risks, particularly for boys.

The study showed that butylparaben, a chemical found in personal care products, was associated with a 1.54-fold increase in asthma risk. Interestingly, exposure to 4-nonylphenol, commonly used in cleaning products and plastics, demonstrated a gender-specific impact: boys exposed to this chemical had a 2.09 times higher risk of asthma, while no such effect was noted in girls. The study raises significant concerns about these phenols, which are widely used as preservatives and antimicrobial agents, and their potential to act as endocrine disruptors during critical developmental periods.
