Analytical human biomonitoring method for the identification and quantification of the metabolite BDCPP originated from the organophosphate flame retardant TDCPP in urine

Tris(1,3-dichloropropyl) phosphate (TDCPP, CAS 13674-87-8) is one of the most commonly used organophosphate flame retardants (OPFRs) in cars, residential furniture and other products containing polyurethane foam to meet the required flammability standards. For the tasks of the working group Analyses in Biological Material from the German...

Standardisation of a European measurement method for the determination of anions and cations in PM2.5: Results of field trial campaign and determination of measurement uncertainty

European Committee for Standardisation (CEN) Technical Committee 264 ‘Air Quality’ has recently produced a standard method for the measurements of anions and cations in PM2.5 within its Working Group 34 in response to the requirements of European Directive 2008/50/EC. It is expected that this method will be used in future by all Member States...

Chemical chacterization of biofuel exhaust emissions

Use of biodiesel is increasing following implementation of various policy instruments and a surge in demand due to growing urbanized populations. A series of experiments to characterize the chemical composition of emissions generated during combustion of petro-diesel (B0), biodiesel blends (B5, B10, B20), biodiesel (B100) and pure plant oil were...

Incident response monitoring technologies for aircraft cabin

The Netherlands Organization for Applied Scientific Research (TNO) was granted by ASHRAE (1306-RP) to conduct scientfic review and feasibility analysis of technologies and methods for measuring aircraft power system contaminants in the cabin air during unanticipated adverse incidents. In particular, the following specific objectives were...

Airliner cabin air quality: Emissions of organophosphates originating from aircraft engine oil. Experimental lab simulation and measurements on flight

In our simulation experiments, using e.g., a dedicated emission chamber, the emission of organophosphates as tricresyl phosphate (TCP) was studied using turbine oil. Experiments were carried out at 250°C and 370°C. Subsequently field studies were carried out to detect the presence of TCPs in the cockpit during normal operating conditions of...

Alveolar epithelial cells (A549) exposed at the air-liquid interface to diesel exhaust: First study in TNO's powertrain test center

Air–liquid interface (ALI) exposures enable in vitro testing ofmixtures of gases and particles such as diesel exhaust (DE). The main objective of this study was to investigate the feasibility of exposing human lung epithelial cells at the ALI to complete DE generated by a heavy-duty truck in the state-of-the-art TNO powertrain test center. A549...

Toxicological characterization of diesel engine emissions using biodiesel and a closed soot filter

This study was designed to determine the toxicity (oxidative stress, cytotoxicity, genotoxicity) in extracts of combustion aerosols. A typical Euro III heavy truck engine was tested over the European Transient Cycle with three different fuels: conventional diesel EN590, biodiesel EN14214 as B100 and blends with conventional diesel (B5, B10, and...

Emission of toxic organic microcontaminants from ship's engines: first measurements on three cruising ships

This work was undertaken within the framework of Lloyd's Register's Marine Exhaust Emissions Research Programme. Phase II of this research programme [] evaluated exhaust emissions from ships in service under steady state and transient modes of operation and incorporated measurements of CO, CO2, 02, SO2, NOa and hydrocarbons on board eight ships....
