Hexavalent chromium (Contaminants)

open access: yesFood Safety, 2019
The Food Safety Commission of Japan (FSCJ) conducted a risk assessment of hexavalent chromium, hereinafter referred to as Cr (VI), related to the amendment of the standards for beverages established by the Ministry of Health, Labour and Welfare. Major toxicities induced by Cr (VI) were damages to small intestine and anemia in experimental animals.

Electrocautery Alters the Near‐Surface Microstructure, Phases, Composition, and Hardness of Ti‐6Al‐4V

open access: yesJournal of Biomedical Materials Research Part A, Volume 114, Issue 1, January 2026.
ABSTRACT Despite the high success rates of total joint arthroplasty procedures, including total knee and hip replacements, implant failures still occur. This study investigated a potential, yet underrecognized, cause of implant failure: unintentional damage from the contact of electrosurgical blades with metal implant alloys.
