Environmental and Molecular Mutagenesis, Volume 67, Issue 5-7, June‐August 2026.ABSTRACT Exposure to air pollution is associated with adverse health effects such as asthma, lung cancer, and cardiovascular diseases. Children are especially vulnerable due to their developing organs, immature immune systems, and higher ventilation rates relative to their body size.

Influence of Phenanthrenes on Microalgal Growth
, 1995 The presence of potential algicides in Juncus effusus was studied. Sequential Et2O and MeOH exts. were made of dried plants that had been collected in spring and summer, and phenanthrenes were purified from the exts. All the free dihydrophenanthrenes and
