Study Claims Occupational Exposure to Engineered Nanomaterials May Be Possible

Lynn L. Bergeson

On September 23, 2009, EHP-in-Press posted an article entitled “Potential for Occupational Exposure to Engineered Carbon-Based Nanomaterials in Environmental Laboratory Studies,” which states that laboratory workers may be at increased risk of exposure to engineered nanomaterials. The goal of the study was to assess the release of carbonaceous nanomaterials into the laboratory atmosphere during handling and sonication into environmentally-relevant matrices. The authors concluded that engineered nanomaterials can become airborne when mixed in solution by sonication, especially when nanomaterials are functionalized or in water containing natural organic matter. EHP-in-Press articles have been peer reviewed and accepted for publication in Environmental Health Perspectives.
