Monitoring of PAHs Profiles in the Urban Air of Dalian, China with Active High-volume Sampler and Semipermeable Membrane Devices Xiuhua Zhu , Chengzhi Zhou , Bernhard Henkelmann , Zhen Wang , Xindong Ma , Gerd Pfister , Karl-Werner Schramm , Jiping Chen , Yuwen Ni , Wei Wang & Jun Mu The concentration of polycyclic aromatic hydrocarbons (PAHs) in the urban air of Dalian, China was monitored from November 2009 to October 2010 with an active high-volume sampler and a semipermeable membrane device (SPMD) passive sampler. The samples were analyzed for the sixteen US EPA priority monitoring PAHs using GC/MS. The concentrations of ∑PAHs in particle and gas phases ranged from 3.2–90.6 ng m−3 and 40.8–155 ng m−3, respectively. The PAHs of 3–4 rings covered 89.2% of the total concentrations (gas phase + particle phase). Furthermore, the gas-particle partitioning phenomena and the results measured from the field versus those predicted by the Junge-Pankow adsorption model, octanol-air partitioning coefficient (K OA) based absorption model, the absorption into the organic matter plus the adsorption to the soot carbon model using the soot-air partitioning coefficients (K SA) were discussed in this article.

The dominant contributors of PAHs in the gas phase of active samples and SPMD passive samples were similar. The SPMD mainly sequestrated gas phase PAHs. The linear correlation coefficients between C SPMD and C air-gas were 0.7316 and 0.7403; C SPMD and C air-total were 0.7397 and 0.7409 at Dalian Jiaotong University sampling site and Dalian Meteorological Observatory sampling site, respectively. The quantitative structure-property relationship (QSPR) of the sampling rate of SPMD for PAHs was studied, which can be predicted by the core–core repulsion energy and the energy of the highest occupied molecular orbital of PAH molecules.

Gl. Skagen is surrounded by unique and magnificent nature. The landscape is characterized by vast and unspoiled moor areas with woods and dunes as well as the gentle Kattegat and the rough North Sea. The two seas collide by Grenen - Denmark's northernmost point. The spit Skagens Odde is a popular excursion point for bird enthusiasts because of the migration. The dune plantation Skagen Klitplantage is located between the two seas and has a scenic and varying landscape. Here you can experience the migrating dune Sandmilen. One of Europe's largest migrating dunes, Råbjerg Mile, is app. 40 m high. It moves annually up to 15 m towards northeast and has created a miniature desert of app. 1 km2 southwest of Skagen. The sand drift has left Råbjerg Stenene - a stone plain, which has come into existence because the fine sand from Råbjerg Mile is moved, and the large rocks stay behind. From the highest point of the migrating dune you can see all the way to Grenen (16 km). The beaches in and around Skagen invite swimming, sunbathing, walks as well as beach and watersport activities.

You can also hike, ride on horses or drive on bicycles in the scenic moor and dune plantations.Furthermore, Skagen offers a bowling alley, a swimming baths and a minigolf course. The angler can throw in the line from the shore, from the pier of the harbour or from a boat. You can also go deep-sea fishing with a fishing vessel, which sails out from the harbour. Lakes and streams of the hinterland offer good fishing opportunities as well. Golfers can test the scenic course of Hvide Klit Golfklub in Bunken, where you will find an 18-hole course as well as a Par-3 course with 6 holes (17 km). Every year in July a music festival with mainly folk music is arranged in Skagen, and during the weekend of the festival, the whole town celebrates. The jewel artist Susanne Lanng has established her workshop and jewel gallery in an old fishing house in Gl. Skagen. The gallery Redningshuset is located in an old and evocative rescue house with sand on the floor. Enjoy the varying exhibitions throughout the year.

The tower of the buried church 'Den Tilsandede Kirke' rises from the sand in a scenic plantation area. The vast sand drift of the area is responsible for the burial of the church (2 km).

At Skagen Museum on Brøndumsvej the paintings, created by the Danish painters of the golden age, are exhibited (5 km).Skagen Odde Naturcenter on Batterivej is an interesting nature centre with the theme natural phenomenon. Interactive exhibitions with the element of wind, water, light and sand are displayed here (6 km). Furthermore, Skagen offers museums with themes like art, natural history, amber and teddy bears.
