Ecotoxicology and Environmental Safety

Triclosan (TCS) is widely applied to daily necessities as a chemical bacteriostatic agent. Environmental TCS levels have increased significantly following the coronavirus disease 2019 pandemic, posing a potential threat to humans and ecosystems. Epidemiological investigations and toxicological studies have shown that long-term TCS exposure can damage human tissues and organs and induce neurodevel…

Persistent synthetic dyes such as crystal violet pose substantial challenges to environmental remediation due to their high structural stability and toxicity. Here, we report a natural photobioelectrocatalytic strategy for dye removal by coupling the photosynthetic bacterium Rhodopseudomonas palustris K7 with natural volcanic lava. Characterization results demonstrated that the lava is an N-type …
