Indoor air concentrations of formaldehyde, furfural, benzaldehyde, and 11 aliphatic aldehydes (C -C ) were measured in residences of 639 participants in the German Environmental Survey for Children and Adolescents 2014-2017 (GerES V). Sampling was conducted using passive samplers over periods of approximately seven days for each participant. The most abundant compounds were formaldehyde and hexanal with median concentrations of 24.

Benzene and acrylamide are carcinogenic substances contained inter alia in tobacco smoke. The mercapturic acid metabolites of benzene, N-acetyl-S-phenyl-L-cysteine (SPMA), and of acrylamide, N-acetyl-S-(3-amino-3-oxopropyl)-cysteine (AAMA) and N-acetyl-S-(3-amino-2-hydroxy-3-oxopropyl)-cysteine (GAMA), were analysed in 2260 first-morning void urine samples from children and adolescents aged 3-17 years, participating in the population-representative German Environmental Survey on Children and Adolescents, GerES V 2014-2017. SPMA was detected in 98% of the participants with a geometric mean (GM) of 0.

Synopsis of recent research by authors named "Robert Bethke"

  • - Robert Bethke's research primarily investigates the exposure of children and adolescents to hazardous indoor air pollutants and chemical metabolites, highlighting the significance of environmental health in youth populations.
  • - One study measured indoor air concentrations of formaldehyde, furfural, benzaldehyde, and various aliphatic aldehydes across 639 residences, revealing that formaldehyde and hexanal were the most prevalent compounds.
  • - Another study focused on the urinary metabolites of benzene and acrylamide in over 2,200 children and adolescents, finding that SPMA, a benzene metabolite, was detected in 98% of participants, emphasizing the widespread exposure to these carcinogenic substances.
