Declining PCB Concentrations in the U.K. Atmosphere: Evidence and Possible Causes

Article Abstract:

This study examined PCB concentrations at a site in northwest England using measurements of air concentrations since 1992, soil samples, and a U.K. mass balance model. The results suggest the PCB decreases in U.K. Air are influenced by many factors.

Assessing the contribution of diffuse domestic burning as a source of PCDD/Fs, PCBs, and PAHs to the U.K. atmosphere

Article Abstract:

Researchers from Lancaster University revealed that domestic refuse burning is one of the major sources of polyaromatic hydrocarbons in the northern U.K. atmosphere

Toward an understanding of the global atmospheric distribution of persistent organic pollutants: the use of semipermeable membrane devices as time-integrated passive samplers

Article Abstract:

Triolein impregnated semipermeable membrane devices (SPMDs) have been found to be effective passive air samplers whose efficiency is comparable to that of conventional air samplers. The devices were deployed at 10 sites aside from the two original test sites and sample evaluations show the latitudinal change in polychlorinated biphenyl (PCB) profiles. Tetra-chlorinated PCB profile was relatively uniform with concentration increasing with increasing latitude and decreasing temperature with the effect inverse for heavier PCBs.
