Effects of lithium nickel manganese cobalt oxide exposure on biological age acceleration: Insights from metabolomics.

The Lithium nickel manganese cobalt oxide (NCM) is a representative new energy material widely used in industry and daily life, but the systemic health influence of exposure to NCM remained largely unknown. This study aimed to reveal the impacts of NCM exposure on biological age acceleration (BAA) and metabolic alteration, as well as the mediating roles of metabolites. NCM exposure was assessed through three methods: external exposure, biomarker of exposure to NCM mixture (Li, Ni, Co, and Mn), with a particular focus on Li exposure.

Metabolomic machine learning predictor for arsenic-associated hypertension risk in male workers.

Arsenic (As)-induced hypertension is a significant public health concern, highlighting the need for early risk prediction. This study aimed to develop a predictive model for occupational As exposure and hypertension using metabolomics and machine learning. A total of 365 male smelting workers from southern regions were selected.

Associations of occupational exposure to micro-LiNiCoMnO particles with systemic inflammation and cardiac dysfunction in cathode material production for lithium batteries.

Micro-LiNiCoMnO (MNCM), a cathode material with highest market share, has increasing demand with the growth of lithium battery industry. However, whether MNCM exposure brings adverse effects to workers remains unclear. This study aimed to explore the association between MNCM exposure with systemic inflammation and cardiac function.
