Our sample of Michigan nail salons shows elevated levels of VOCs that are associated with nail salon products. Exposure to VOCs is associated with a wide range of adverse health effects. Important results for OH&S practitioners from this research include: the demonstration that MMA is used in nearly all salons, despite restriction on this product; estimates that worker exposure to VOCs (determined using personal monitoring) is 1.2 to 2.0 times higher than area measurements; and the presence of low and possibly inadequate ventilation rates in a subset of salons. Some of the methodological findings of interest to OH&S practitioners include: demonstrating how VOCs can be apportioned using chemical mass balance modeling; the identification of products responsible for emissions; and the demonstration that “informal” short-term sampling approaches can facilitate access to salons and provide useful measurements.

For policy-makers and more broadly, the industry, it is important to realize that NSTs represent a large and potentially vulnerable population. The VOC levels found, particularly for MMA and EMA, suggest the need for better controls. VOC exposures can be controlled by many means: appropriate licensing and certification requirements; setting and complying with standards and guidelines that recognize the potential sensitivity of the population; disclosing and translating product safety information for all products (e.g., adopted from material safety data sheets and translated into Korean, Vietnamese, and other languages common in the industry); improving point and area ventilation; and restricting product ingredients. Steps to ensure that salons are healthy and sustainable environments include: coordination and information-sharing among stakeholders (NSTs, salon owners, building managers, engineers, architects, health scientists, policy makers, etc.); outreach, education and training for salon owners and NSTs regarding best practices; and restrictions on nail product formulations.
