Superacid-promoted synthesis of polychlorinated dibenzofurans [PDF]

Tetrahedron Letters, 2016
Abstract Polychlorinated dibenzofurans have been prepared in one step by the condensations of o -chloranil with arenes in triflic acid. A mechanism is proposed involving formation of a monoprotonated quinone (carboxonium ion), electrophilic attack at the arene, and cyclization of a carbocation intermediate.

Nontargeted biomonitoring of halogenated organic compounds in two ecotypes of bottlenose dolphins (Tursiops truncatus) from the Southern California Bight. [PDF]

, 2015
Targeted environmental monitoring reveals contamination by known chemicals, but may exclude potentially pervasive but unknown compounds. Marine mammals are sentinels of persistent and bioaccumulative contaminants due to their longevity and high trophic ...

Impact of Environmental Exposure on Infant Sleep : The Exposome Approach

Journal of Sleep Research, EarlyView.
This review explores how exposure to environmental pollutants during the first 1000 days of life may affect infant sleep. Evidence suggests potential links between chemical exposures and sleep disturbances, underscoring the need for more research on early‐life vulnerability and the impact of pollutants in air, diet, and breast milk.
