1. 1. Methods for Determination of Benzo(a)pyrene and High Molecular Weight (>300 Da) Polycyclic Aromatic Hydrocarbons in Particulate Matter from Ambient Air and Vehicle Exhausts

   Författare :Christoffer Bergvall; Roger Westerholm; Stephen Wise; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAH; dibenzopyrene; benzo a pyrene; standard reference material; air particulate matter; diesel particulate matter; toxic equivalence factor; ultrasonic assisted extraction; accelerated solvent extraction; automation; online coupling; GC MC; LC GC MS; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Sammanfattning : Air pollution with particulate matter (PM) raises considerable concern because of its adverse effects on human health. For this reason, and because the mechanisms of PM toxicity are not fully known, there is an urgent need to determine the chemical constituents of atmospheric PM, especially PM emanating from traffic - a major source of urban PM.

3. 2. Automation, hyphenation and multidimensional chromatography for PAH analysis : Analytical techniques to simplify sample complexity

   Författare :Hwanmi Lim; Roger Westerholm; Christoffer Bergvall; Stephen Wise; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polycyclic aromatic hydrocarbon; PAH; benzo[a]pyrene; B[a]P; carcinogenicity; cancer risk assessment; complex matrix; automation; hyphenation; multidimensional chromatography; two-dimensional; method translation; online fractionation; benz[j]aceanthrylene; B[j]A; relative potency factor; Analytical Chemistry; analytisk kemi;

   Sammanfattning : One group of organic environmental pollutants which are potentially hazardous to human health is polycyclic aromatic hydrocarbons (PAHs). These compounds consist of two or more benzene rings in their structure among which benzo[a]pyrene (B[a]P) is classified as a human carcinogen. LÄS MER
