Chemical Composition and Transgenerational Effects on of Seasonal Fine Particulate Matter.

While numerous studies have demonstrated the adverse effects of fine particulate matter (PM) on human health, little attention has been paid to its impact on offspring health. The multigenerational toxic effects on () were investigated by acute exposure. PM and PM samples were collected and analysed for their chemical composition (inorganic ions, metals, OM, PAHs) in different seasons from April 2019 to January 2020 in Lin'an, China.

Reproductive toxicity and underlying mechanisms of fine particulate matter (PM) on Caenorhabditis elegans in different seasons.

Although numerous studies have investigated that atmospheric fine particulate matter (PM) can be toxic to environmental organisms, the research on the reproductive toxicity of PM is limited, and the key toxic components and underlying mechanisms remain unknown. In this work, PM samples of four seasons in Nanjing from March 1, 2021, to February 28, 2022 were collected and the chemical components were analyzed. Caenorhabditis elegans (C.
