Sunscreen Pollution is described as the entrance of sunscreen products into waterways thereby polluting them. Sunscreens have the potential to harm numerous aquatic organisms which have impacts on coastal communities. It is generally accepted that micron-sized inorganic sunscreens are less harmful than other types, however it is unknown to what extent this is recognized by adolescents and whether this knowledge has any relation with their choice of sunscreen. A survey was adapted from Casas-Béltran et al and modified to resolve this. This was administered to 3 high schools on Long Island, New York. Results indicated that adolescents using micron-sized inorganic sunscreens were more knowledgeable about sunscreen pollution than those who used organic sunscreens and those who did not apply sunscreen (p = .046, p = .045). Also a relative minority of participants indicated that they knew sunscreens were harmful to aquatic wildlife (10/62). Additionally, it was estimated 0.0279 tons of sunscreen were discharged yearly during the summertime by adolescents into waterways surrounding Long Island which is a large figure. These findings suggest that further education of the issue of sunscreen pollution and what the least harmful sunscreens are may lead to more micron-sized inorganic sunscreen use and lessen the effects on the environment.
