Saliva-induced coacervation of inverted aggregates of hexanol for simplifying human biomonitoring: Application to the determination of free bisphenols.

Saliva is progressively becoming a useful alternative to urine and blood to assess human exposure to toxics in biomonitoring campaigns, because of its easy and stress-free collection by unskilled personnel. This evaluation is highly challenging owing to the large number of compounds and individuals involved. In this article, we propose a new strategy to simplify sample treatment in the human biomonitoring of toxics in saliva.

Presence of diphenyl phosphate and aryl-phosphate flame retardants in indoor dust from different microenvironments in Spain and the Netherlands and estimation of human exposure.

Phosphate flame retardants (PFRs) are ubiquitous chemicals in the indoor environment. Diphenyl phosphate (DPHP) is a major metabolite and a common biomarker of aryl-PFRs. Since it is used as a chemical additive and it is a common impurity of aryl-PFRs as well as a degradation product, its presence in indoor dust as an additional source of exposure should not be easily ruled out.
