Nail Salon Air Shows Chemical Spikes in NYC
A week-long study of five New York City nail salons found volatile organic compound levels that varied widely and spiked repeatedly during working hours.

Researchers tracking air quality minute-by-minute in five New York City nail salons found chemical exposure risks for workers greater than previously understood, according to a study published in Risk Analysis. Volatile organic compound concentrations spiked repeatedly throughout the workday.
Why it matters
Full-shift averages can miss short-term peaks, so workers' exposure may be underestimated by conventional measurement approaches. The findings add to concern about chemicals used in nail products in a city with many salons.
The study used continuous photoionization detector monitoring and chemical-specific thermal desorption tube sampling across five salons over one week. Modeled benzene cancer risks exceeded the EPA's 1-in-1-million benchmark in several salons under certain exposure scenarios, though upper-bound noncancer estimates exceeded the benchmark only in the salon with the highest VOC levels.
The players
Risk Analysis
Risk Analysis is a peer-reviewed journal published by the Society for Risk Analysis that covers risk assessment and risk management research.
U.S. Environmental Protection Agency
The U.S. Environmental Protection Agency is the federal agency responsible for setting environmental and public health standards, including the cancer risk benchmark referenced in the study.
The details
Researchers found that the most commonly detected chemicals were ethyl acetate, acetone, n-butyl acetate, and methyl acetate, with benzene present at low concentrations. Methacrylates, associated with artificial nail products, and low-level benzene in some nail products are cited as possible sources.

The Big Picture
The study's benzene findings are measured against the EPA's 1-in-1-million lifetime cancer risk benchmark, a standard the agency uses to judge environmental carcinogen exposure. Applying that threshold to nail salon workers shows that exposure in some scenarios exceeds the level regulators typically treat as acceptable.
Nail salon workers and frequent clients may face short-term chemical peaks that daily averages don't capture, which matters for anyone spending extended time in these spaces. Ventilation and product choice are the practical factors that determine how much exposure occurs in a given salon.
The takeaway
Average air quality numbers can hide brief but intense chemical spikes, so workers and customers in nail salons should consider ventilation and product ingredients when assessing exposure. The findings suggest that measuring peak concentrations, not just shift averages, gives a fuller picture of risk.
