Occurrence, Fate and Treatment Methods of Polycyclic Aromatic Hydrocarbons, Polychlorinated Biphenyls, Dioxins and Furans: A Mini Review

In Situ Thermal Desorption for Treatment of POPs in Soils and Sediments

C-1 POPS-WASTES APPLICABILITY (REFS. 4 AND 16): ISTD is a thermally enhanced in-situ treatment technology that uses conductive heating elements to directly transfer heat to environmental media. ISTD can heat soil or sediment in situ to average temperatures of 1,000 degrees Fahrenheit (°F), and as a result has been used to treat compounds with relatively high boiling points. Some of these includ...

A Study of the Critical Uncertainty Contributions in the Analysis of PCBs in Ambient Air

The measurement of polychlorinated biphenyls (PCBs) in ambient air requires a complex, multistep sample preparation procedure prior to analysis by gas chromatography-mass spectrometry (GC-MS). Although routine analytical laboratories regularly carry out these measurements, they are often undertaken with little regard to the accurate calculation of measurement uncertainty, or appreciation of the...

Current Status of Air Toxics Management and Its Strategies for Controlling Emissions in Taiwan

Since the 1970s, hazardous air pollutants (HAPs), so-called air toxics, have been of great concern because they can cause serious human health effects and have adverse effects on the environment. More noticeably, some of them are known to be human carcinogens. The objective of this paper is to investigate the regulatory systems and human health effects of air toxics which have been designated b...
