MedicalResearch.com: What is the background for this study? What types of particles, ie where do they come from?
Response: This work is a continuation of my research on nanoparticles in consumer products. We have investigated and published on the release of particles from nano-enabled consumer products, such as cosmetic powders, various sprays and clothing.
In this project, we were interested in potential resuspension of particles once nano-enabled consumer sprays are used. The particles are added into consumer products to provide them certain desired properties, like antimicrobial protection, odor reduction or protection against UV (sunscreen). Once the products are used, the particles are released and we could be exposed to them.

MedicalResearch.com: What is the background for this study? What is the significance of tritan?
Response: Bisphenol A (BPA) is used widely in the manufacturing of consumer plastic goods. Researchers and the general public increasingly recognize the potentially harmful effect of BPA. These days BPA-based polycarbonate plastic water bottles have all but disappeared in most US stores, replaced by various BPA-free bottles including Tritan bottles.
Tritan is a plastic that is not based on BPA or BPA analogues. In earlier studies, we unexpectedly found transient release of BPA from some Tritan bottles. Similar results have been reported in a past study. We wanted to figure out why the BPA release from Tritan bottles, and how consumers can best clean their bottles.
