Benzotriazole (BTR) and benzothiazole (BTH) derivatives are used in a wide variety of industrial and consumer products and have been reported to occur in the environment. Owing to a lack of analytical methods, human exposure to BTR and BTH is

Aneuploidy can instigate tumorigenesis. However, mutations in genes that control chromosome segregation are rare in human tumors as these mutations reduce cell fitness. Screening experiments indicate that the knockdown of multiple classes of genes that are not directly involved in

Benzotriazole (BTR) and benzothiazole (BTH) derivatives are extensively applied in industrial processes and consumer products, and are thus frequently detected in the environmental matrices. Due to their potential estrogenic effects reported in animal studies, the assessment of human exposure to

This paper presents the results of a number of field and laboratory studies to evaluate the environmental impact of aircraft deicing and anti-icing fluids (ADAFs) on aquatic systems. Both 5-methyl-1H-benzotriazole (5-MeBt) and 4-methyl-1H-benzotriazole (4-MeBt), known additives to ADAFs, were found

This work proposes a new approach for the simultaneous determination of benzothiazoles, benzotriazoles and benzosulfonamides in different environmental matrices and human urine, using solid-phase microextraction coupled with gas-chromatography-triple quadrupole mass spectrometry (SPME-GC-QqQMS). The analytes object of this investigation have been
