“…Higher mass PAH are found primarily adsorbed to particulate material. 6 Several PAH, primarily with molecular masses of 228 Da and above, have been classified as carcinogens. 7,8 Differentiation between PAH sources in complex environmental samples has been approached qualitatively using PAH ratios 9 and quantitatively using a variety of multi-variate methods.…”

A variety of polycyclic aromatic hydrocarbon (PAH) diagnostic ratios were examined as source apportionment tools in the analysis of a PAH data set associated with atmospheric particulate matter collected in an urban-industrial environment. Seventy-six PM(10) samples were collected concurrently at 4 sampling sites over a one-month period in Hamilton, Ontario, Canada, a city of 500 000 people that is home to two integrated steel companies, associated industries and a network of roadways and major highways. Samples collected under well defined meteorological conditions were categorized as being 'upwind' or 'downwind' of the industrial sector. All sample extracts were analyzed for 48 parent PAH, methylphenanthrenes and sulfur-containing aromatics and showed a thousand-fold range of total PAH concentrations (0.23-172 ng m(-3)). Of all PAH diagnostic ratios examined, the two most useful were the anthracene/(anthracene+phenanthrene) and benz[a]anthracene/(benz[a]anthracene+chrysene/triphenylene) ratios. These afforded the best discrimination of samples that had significant industrial impacts. This work is the first example of the use of a linear combination of PAH ratios, coupled with total PAH data and well defined local samples to determine the relative impacts of mobile and industrial emissions in an urban-industrial environment. Use of a linear combination of PAH ratios allowed us to categorize 95% of the data as 'upwind' or 'downwind' of the industrial sector. It is important to determine PAH ratio threshold values based on data from well defined local samples rather than relying on literature values alone.

“…The only available data are for emissions from the oil-furnace process. These data show mercury emission to be 1.5 x 10-4 kg/Mg (3 x 10 -4 lb/ton) from the main process vent (Serth and Hughes, 1980). The source of these data could not be obtained in order to validate the emission factors.…”

“…However, Al 3+ can cause harm to human beings when it is exposed to high concentration levels [17]. Aluminum is regarded as a toxic element, because Al 3+ can cause damage to central nervous system and immune system in human bodies [18], affecting the absorb and use of other trace elements [19], and induce many health problems, such as Alzheimer's disease and Parkinson's disease [20]. Nevertheless, there have been only a few reports about the development of fluorescent chemosensors for Al 3+ because of its poor coordination ability [21].…”
