Mixture Effects of Metals, PCBs, Dioxins, and Furans on Liver Function [PDF]

Toxics
Quantifying the mixture effects on humans exposed remains challenging because mixture components are correlated and may act bidirectionally by exhibiting nonlinear dose-response relationships, which may contribute to subclinical organ dysfunction.

Polychlorinated biphenyls and breast cancer: evidence, mechanisms, and risk management [PDF]

Frontiers in Cell and Developmental Biology
Epidemiological inconsistencies currently obscure the causal link between polychlorinated biphenyls (PCBs) and breast cancer. This review synthesizes multi-disciplinary evidence to characterize PCBs not as passive exposure correlates but as active ...

Mixture of organic pollutants is associated with cognitive aging [PDF]

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Environmental organic pollutants impact brain function and cognitive aging, but the effect of real‐world complex mixtures of these pollutants is unexplored. METHODS Using data collected at two time points from 170 cognitively normal adults, we used hierarchical Bayesian kernel machine regression to examine the association between ...
