Deriving a Health-Based Guidance Value for 9,10-Anthraquinone via integrating PBTK modeling-based reverse dosimetry and In Vitro bioassays.

Anthraquinones, both naturally occurring and synthetic, are widely distributed in the environment. Recent years, human exposure to 9,10-anthraquinone (9,10-AQ) through contaminated food has been raising significant health concerns due to its potential toxicity upon chronic exposure. Among these, 9,10-AQ has been studied in traditional toxicology, with few of established Points of Departure (PoDs) and Health-Based Guidance Values (HBGV).

Comet Assay Evaluation of Lanthanum Nitrate DNA Damage in C57-ras Transgenic Mice.

Due to the wide application of rare-earth elements (REEs) in the last decades, lanthanum has increasingly entered the environment and has gradually accumulated in the human body through the food chain. Lanthanum is worth paying attention in terms of food safety. Although the genotoxicity of lanthanum has been studied in vitro, data on its DNA damage in vivo rodent are limited, moreover, which have also presented some controversy.
