Cometabolism of Trihalomethanes by Nitrosomonas europaea [PDF]
Applied and Environmental Microbiology, 2005 ABSTRACT The ammonia-oxidizing bacterium Nitrosomonas europaea (ATCC 19718) was shown to degrade low concentrations (50 to 800 μg/liter) of the four trihalomethanes (trichloromethane [TCM], or chloroform; bromodichloromethane [BDCM]; dibromochloromethane [DBCM]; and tribromomethane [TBM], or bromoform ...

PLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 792-810, May 2026.Contaminants of emerging concern (CECs) in agriculture represent a growing global challenge for food safety and public health. In this review, we synthesized evidence on how substances such as pharmaceuticals, microplastics, and per‐ and polyfluoroalkyl substances (PFAS) enter soils, accumulate in crops, and affect ecological and human health. We found
