Article Synopsis
- There are significant gaps in research about adults' hand-to-mouth touching behavior, which is important for understanding health risks from accidental ingestion of harmful substances.
- The study observed 14 participants performing various tasks to analyze how often and where they touched their faces, focusing on hand contact surfaces.
- Findings showed that during most tasks, participants frequently touched their faces, with an average of 27.7 face touches during non-installation tasks, primarily with their palms, suggesting specific health implications based on what their hands might be carrying.

To our knowledge, no risk assessment studies using exposure data from historical exposures or chamber simulations have been published. We conducted activity-based sampling with cosmetic talcum powder samples from five opened and previously used containers that are believed to have been first manufactured and sold in the 1960s and 1970s.

Methods: The meta-analysis included 11 case-control studies and one cohort study. We evaluated heterogeneity across studies and conducted sensitivity and influence analyses.
Work-related exposures potentially associated with a cluster of brain tumors at a petroleum exploration and extraction research facility were evaluated in a nested case-control study. Fifteen cases were identified in the original cohort and 150 matched controls were selected. Odds ratios (ORs) for occupational exposure to petroleum, radiation, solvents, magnetic fields, and work activities were near or below 1.
