Article Abstract
This study aimed to identify the effects of major metal components present in particulate matter (PM)2.5 on the reproductive system, sperm function, and embryo development. Through intratracheal instillation, male mice were exposed to various concentrations of metal components, including calcium oxide (Ca), iron oxide (Fe), aluminum oxide (Al), zinc oxide (Zn), lead oxide (Pb), and a mixture of these metals, in PM2.5 collected from the porcine farm. After 14 days, testicular inflammation and abnormal sperm morphology were observed in the exposed mice. These results indicate that such metal exposure enhances inflammatory cytokines in the testis and oxidative stress-induced apoptosis. Moreover, the exposure influenced sperm deformation, capacitation status, testosterone levels, and testosterone biosynthesis. Importantly, embryo development was also found to be impacted due to decreased sperm fertility. This study demonstrates that major metal components of PM2.5 derived from porcine farm pose adverse effects on the male reproductive system.

Lithium metal batteries (LMBs) offer exceptional energy density and output voltage. However, their practical application remains hindered by sluggish ion transport and uncontrolled lithium dendrite formation, particularly under fast-charging conditions. Here, we report a facet-engineered anion-regulating separator based on zeolitic imidazolate framework-8 (ZIF-8) with preferentially crystal-exposed (110) facets.

Excessive fossil fuel combustion has accelerated renewable energy development, with hydrogen energy emerging as a promising alternative due to its high energy density and environmental compatibility. Photocatalytic hydrogen production through solar energy conversion represents a viable approach for sustainable development. Metal-organic frameworks (MOFs) have garnered significant research interest owing to their structural tunability, well-defined catalytic sites, and post-synthetic modification capabilities.

This exploratory study surveyed seven contaminated brownfields and Superfund sites in Southern California to identify locally adapted species tolerant of mixed organic and metal contamination under arid and semi-arid conditions. Five novel native plants, including Brickellia californica, Baccharis salicifolia, Baccharis sarothroides, Eriogonum fasciculatum, and Heterotheca grandiflora were identified as hyperaccumulators of copper (Cu), alongside a non-native species from the Asteraceae family, Helminthotheca echioides. Additional metal-accumulating plants (including native plants) for lead (Pb), chromium (Cr), arsenic (As), and nickel (Ni) were identified, and warrant further evaluation for their phytoremediation potential.
