Archives of toxicology

Wrobel SA, Bury D, Hayen H, Koch HM, Brüning T, Käfferlein HU.
PMID: 34642770
Arch Toxicol. 2022 Jan;96(1):121-134. doi: 10.1007/s00204-021-03159-0. Epub 2021 Oct 13.

Few human data on exposure and toxicity are available on neonicotinoids and neonicotinoid-like compounds (NNIs), an important group of insecticides worldwide. Specifically, exposure assessment of humans by biomonitoring remains a challenge due to the lack of appropriate biomarkers. We...

The article 'Quantification of N-phenyl-2-naphthylamine by gas chromatography and isotope-dilution mass spectrometry and its percutaneous absorption ex vivo under workplace conditions' written by Heiko Udo Käfferlein, was originally published electronically on the publisher's internet portal (currently SpringerLink) on 12th...

Metabolism and elimination of N-ethyl-2-pyrrolidone (NEP) in human males after oral dosage.

Archives of toxicology

Arch Toxicol. 2014 Apr;88(4):893-899. doi: 10.1007/s00204-013-1150-1. Epub 2013 Nov 14.

N-Ethyl-2-pyrrolidone (NEP) is an industrial solvent that has been increasingly used to substitute N-methyl-2-pyrrolidone. NEP is under scrutiny in scientific and regulatory committees because of developmental toxic and teratogenic effects in rodents. The two postulated NEP metabolites 5-hydroxy-N-ethyl-2-pyrrolidone (5-HNEP)...
