Method development and field measurements for polar volatile organic compounds in ambient air
Article Abstract:
Polar volatile organic compounds (PVOCs) in ambient air can be analysed using gas chromatographic separation of PVOCs and quantification through a quadrupole ion trap mass spectrometer. This represents an important step forward in the development of sampling and analysis methods for PVOCs, which are behind those for nonpolar volatile organic compounds (VOCs). The new method has a number of advantages, including the fact that the ion trap detector is mainly unaffected by water vapour in samples collected in canisters, and PVOC levels in ambient air collected in stainless steel canisters can be analysed up to four days later.

Status of ambient measurement methods for hazardous air pollutants
Article Abstract:
The implementation of the 1990 Clean Air Act Amendments require effective methods for measuring hazardous air pollutants (HAP). However, a survey conducted by the EPA on 189 HAP measurement methods used in health risks assessments showed that only 126 of the methods are suitable for ambient air measurements, although all of them are approved by the EPA. These findings indicate the need for a more focused methods development and validation to overcome the effects of the diversity of the HAP factor on the performance of various instrumentations and methods.

Monitoring methods for polycyclic aromatic hydrocarbons and their distribution in house dust and track-in soil
Article Abstract:
A pilot field study was conducted to develop monitoring methods for polycyclic aromatic hydrocarbons (PAHs) and their distribution in house dust and track-in soil. Nineteen PAHs were identified, ranging from the two-ring naphthalene to the seven-ring coronene. The concentration trend was found to be entryway soil > house dust > pathway soil > foundation soil. The PAH levels in house dust correlated well with levels in entryway soil.
