Pesticides in the Indoor Environment of Residential Houses: A Case Study in Strasbourg, France.

Indoor environmental exposure to pesticides has become one of the major concerns that might adversely affect human health and development. People spend most of their lifetime in enclosed indoor environments where they might inhale harmful toxic chemicals, such as pesticides, dispersed either in particulate or in a gas phase. In this study, an assessment of pesticide contamination in indoor environments was conducted.

Identification of Postblast Residues by DART-High Resolution Mass Spectrometry Combined with Multivariate Statistical Analysis of the Kendrick Mass Defect.

The coupling of an atmospheric pressure ionization source (Direct Analysis in Real Time, DART) and a high-resolution mass spectrometer (Orbitrap) has enabled the rapid and efficient analysis of a variety of energetic formulations. This approach was used to generate mass spectra for 83 plastic explosives and polymer samples in less than 2 min per sample. To manually interpret and identify all of the constituent polymers and other interesting features in the acquired mass spectra is a tedious and time-consuming challenge.
