Development and validation of a UPLC-MS/MS method for the quantification of isothiazolinones in the composition and emissions from consumer products.

Isothiazolinones, a family of biocides, are used as preservatives for their fungicidal, bactericidal, and algacidal properties. These compounds can be found in a wide range of consumer and building products, such as paints, varnishes, shampoos, and liquid detergents. A robust analytical UPLC-MS/MS method to identify and quantify seven isothiazolinones (MIT, CMI, BIT, MBIT, BBIT, OIT, and DCOIT) in consumer products and their emissions was developed and validated according to ISO/IEC 17025.

Emission characteristics of air pollutants from incense and candle burning in indoor atmospheres.

Volatile organic compounds (VOCs) and particles emitted by incense sticks and candles combustion in an experimental room have been monitored on-line and continuously with a high time resolution using a state-of-the-art high sensitivity-proton transfer reaction-mass spectrometer (HS-PTR-MS) and a condensation particle counter (CPC), respectively. The VOC concentration-time profiles, i.e.

Characterization of VOC and formaldehyde emissions from a wood based panel: results from an inter-laboratory comparison.

Six European laboratories used the emission test chamber method (EN ISO 16000-9) for the determination of VOC and formaldehyde emissions from a wood based panel (particleboard). The tested panel was conditioned without wrapping over 28 d at 23 degrees C and 50% RH before shipping to each participating laboratory. Emission chamber testing was carried out with air sampling after 3 and 28 d.

[A methodology for the evaluation of the health related and environmental characteristics of building products].

A global methodology for the evaluation of the environmental and health-related characteristics of building products is presented. This methodology is based on environmental product declaration according to the NF P 01-010 standard for the environmental part and on specific tests for the characterization of the potential health-related impact of building products (emissions of volatile organic compounds and formaldehyde in indoor air, odour emissions, aptitude for growth of micro-organisms: moulds and bacteria, natural radioactive emissions). This methodology can be used either by: *Manufacturers for the communication on the environmental and health-related properties of their building products, *End users, consumers, retailers, building owners and architects wishing to introduce environmental and health-related criteria in their selection procedure of building products, e.

[Effects of clonazepam taken per os by children with rebellious epileptic encephalopathies].

The effect of clonazepam, taken per-os and in very progressive doses, has been studied by the authors on fourteen children afflicted with evolutive epileptic encephalopathies and still presenting, in spite of heavy anti-epileptic polychemio-therapies, alarming clinical and electrical manifestations. Clonazepam proved to be an efficient contributive factor in the course of a curing process since, in 70% of the cases, it produced quite a visible amelioration. Its efficient action seems to last longer than that of other diazepines since half of their patients have now been treated with it for more than a year with, as a result, a constant clinical and electrical amelioration.
