What can we learn about ship emission inventories from measurements of air pollutants over the Mediterranean Sea?
ship emission inventories air pollutants Mediterranean Sea
2009/9/23
Ship emission estimates diverge widely for all chemical compounds for several reasons: use of different methodologies (bottom-up or top-down), activity data and emission factors can easily result in a...
Source regions of some persistent organic pollutants measured in the atmosphere at Birkenes, Norway
persistent organic pollutants atmosphere Birkenes Norway
2009/9/14
A key feature of POPs (Persistent Organic Pollutants) is their potential for long-range atmospheric transport. In order to better understand and predict atmospheric source-receptor relationships of PO...

bioaccumulative air pollutants Mezquital Valley Mexico
2009/9/14
Mezquital Valley (MV), a Mexican wastewater-based agricultural and industrial region, is a "hot spot" of regulated air pollutants emissions, but the concurrent unregulated ones, like hazardous metals ...
Characteristics of trace gaseous pollutants at a regional background station in Northern China
trace gaseous pollutants regional background station Northern China
2009/3/13
Measurements of trace gaseous pollutants were taken at the Shangdianzi site, a WMO Global Atmosphere Watch (GAW) background station in Northern China. The results are presented for the period from Sep...
Vehicle fleet emissions of black carbon, polycyclic aromatic hydrocarbons, and other pollutants measured by a mobile laboratory in Mexico City
Vehicle fleet emissions black carbon polycyclic aromatic hydrocarbons Mexico City
2009/2/19
Black carbon (BC) and polycyclic aromatic hydrocarbons (PAHs) are of concern due to their effects on climate and health. The main goal of this research is to provide the first estimate of emissions o...
Impact of the regional climate and substance properties on the fate and atmospheric long-range transport of persistent organic pollutants - examples of DDT and γ-HCH
regional climate substance property atmospheric long-range transport persistent organic pollutants DDT γ-HCH
2009/1/6
A global multicompartment model which is based on a 3-D atmospheric general circulation model (ECHAM5) coupled to 2-D soil, vegetation and sea surface mixed layer reservoirs, is used to simulate the ...
GEM/POPs: a global 3-D dynamic model for semi-volatile persistent organic pollutants – Part 2: Global transports and budgets of PCBs
3-D dynamic model semi-volatile persistent organic pollutants transports PCBs
2008/12/16
Global transports and budgets of three PCBs were investigated with a 3-D dynamic model for semi-volatile persistent organic pollutants – GEM/POPs. Dominant pathways were identified for PCB transports ...
