Development of skin diseases following systemic exposure: example of dioxins

Frontiers in Toxicology, 2023
Most skin manifestations of exposure to toxic compounds are a consequence of a direct contact with the toxicants. However, some toxicants may reach the skin following systemic exposure, and promote skin diseases.

Pollutants Transformation During the Regeneration Process of Fluid Catalytic Cracking Catalysts

Angewandte Chemie, Volume 137, Issue 52, December 22, 2025.
Fluid catalytic cracking is the main pollutant source in crude oil refineries due to spent catalyst regeneration. In this work, flue gas pollutants are monitored and coke deposits are identified. Operando and in situ spectroscopy are developed to explore coke species evolution, coupled with online gas infrared spectroscopy to detect pollutant formation.
