A recent University of Toronto study, in collaboration with Parkdale Queen West Community Heath Center and the Healthy Nail Salons Network, shows that nail technicians in discount salons are exposed to several chemicals widely used as plasticizers and flame retardants.

The study, to be published Feb. 14 in the journal Environmental Science and Technology, found that exposure to some was higher among nail technicians than among electronic waste workers.

"We were very surprised to find exposures for some chemicals up to 30 times higher among nail salon workers relative to exposures in homes, and up to 10 times higher than in e-waste handling facilities," said Miriam Diamond, co-author and professor at the University of Toronto's Department of Earth Sciences.

The study reported higher exposures of several phthalate plasticizers, which was expected given the use of these chemicals in personal care products. One phthalate plasticizer, DEHP, which is not allowed for use in cosmetics under the Canadian Environmental Protection Act, was found at low levels. "The finding of low exposure to the plasticizer DEHP is important—it shows the current regulations for this compound are working," Diamond said.

However, what was unexpected was the finding of some high levels of flame retardants that are not known to be used in personal care products.

Several of the chemicals studied have some restrictions on their use (or restrictions are proposed) under the Canadian Environmental Protection Act. However, most of these chemicals are not explicitly regulated in Ontario workplaces. The specific source of these chemicals in nail salons was not determined in this study.

These chemicals have been associated with including neurological and reproductive effects, with some evidence that in utero exposure may be important.

"Nail technicians have been raising concerns about the impact of their work on their bodies, including worries about reproductive, respiratory, skin and musculoskeletal health for many years now," said Victoria Arrandale, co-author and assistant professor at the University of Toronto's Dalla Lana School of Public Health.

Despite these concerns, nail technicians enjoy the artistry and that their work entails.

"This research shows us that our needs to pay attention to making the products that are used in nail salons safer, for both customers and nail technicians."," said Van Tran, nail technician and Nail Salon Outreach Worker at Parkdale Queen West Community Health Center.

This study points to the need to consider the wide range of workplace settings when regulating use in Canada. Study authors urge government and product manufacturers to make safer and safer spaces for workers and customers in the personal services sector.

The study was a joint effort of researchers at the University of Toronto, Occupational Cancer Research Center, Center for Research Expertise in Occupational Disease, and the Parkdale Queen West Community Health Center. The aim of the study was to better understand workplace hazards in discount salons.
