PAHs in fog and fingerprinting oil spills on the cover of Issue 11

The hot articles on our cover this month are from Xiang Li and Jiamin Chen (Fudan University) and Zhendi Wang (Environment Canada).

The futuristic image on the outside front cover image highlights the work from Li et al on solid-phase microextraction (SPME) analysis of PAHs in fog.  Polluted fog is a serious problem in Shanghai, where the study took place, and this research should provide a basis for better understanding of PAHs in fog-rain events.

On the inside front cover another serious environmental issue is highlighted – oil spills.  Wang et al present a case study of the 2009 Sarnia (Ontario) spill, using GC and GC-MS to characterize the chemical composition and determine the source of the oil spill by identifying oil ‘fingerprints’ through characteristic biomarkers and statistical correlation of target diagnostic ratios.

    Fog is really a concern!

    Heavy fogs just hit Beijing, Haerbin, Dalian, Shenyang, Jinan and other cities in China from Oct. 30 to Nov. 6, 2011. The visibility in some areas were less than 100 meters. Due to the heavy fogs, at least 20 highway toll stations around Jinan were closed, over hundreds of flight were delayed or cancelled, more than 200 ships on remain stranded in the Three Gorges section of the Yangtze River, and at least 30 people have been killed and dozens of others were injured in pile-up accidents on mist-shrouded expressways. Moreover, citizens worried about polluted fog as bad odours occurred in some cities. Fog is a severe weather hazard that greatly influences traffic and daily life with potentially heavy economic loss. The highly concentrated chemical composition of fog water (see a paper by Li at al., Atmos. Environ., 45:4034-4041, 2011) in polluted cities like Shanghai is a potential hazard for human health. On this point, the present paper as a hot article on JEM cover shows that a plenty of PAHs contributing carcinogenic and mutagenic morbidity and mortality were found in fog. The physico-chemical interactions among gaseous pollutants, atmospheric particles and fog droplets can all influence the composition of fog droplets. Fog chemistry could be a very interesting in complementary interpretation and identification of long range transport and of air pollutants. We do think a more systematic studies on fog chemistry in different circumstances are of greater concerns.
