Source apportionment modeling of volatile organic compounds in streams.
It often is of interest to understand the relative importance of the different sources contributing to the concentration c(w) of a contaminant in a stream; the portions related to sources 1, 2, 3, etc. are denoted c(w,1), c(w2), c(w3), etc. Like c(w), the fractions alpha1 = c(w,1)/c(w), alpha2 = c(w,2)/c(w), alpha3 = c(w,3)/c(w), etc. depend on location and time. Volatile organic compounds (VOC...
متن کاملApplication of a source apportionment model in consideration of volatile organic compounds in an urban stream.
Position-dependent concentrations of trichloroethylene and methyl-tert-butyl ether are considered for a 2.81-km section of the Aberjona River in Massachusetts, USA. This river flows through Woburn and Winchester (Massachusetts, USA), an area that is highly urbanized, has a long history of industrial activities dating to the early 1800s, and has gained national attention because of contamination...
متن کاملSource apportionment of exposure to toxic volatile organic compounds using positive matrix factorizationSource apportionment of exposure to toxic volatile organic compounds using positive matrix factorization
Data from the Total Exposure Assessment Methodology studies, conducted from 1980 to 1987 in New Jersey (NJ ) and California (CA) , and the 1990 California Indoor Exposure study were analyzed using positive matrix factorization, a receptor -oriented source apportionment model. Personal exposure and outdoor concentrations of 14 and 17 toxic volatile organic compounds (VOCs) were studied from the ...
متن کاملSource Apportionment Of High Reactive Volatile Organic Compounds In a Region With The Massive Hydrocarbon Processing Industries
In the Persian Gulf region, conditions are highly favorable for ozone air pollution and the region is a hot spot of photochemical smog. The vast activities in processing oil and gas play a major role in it. It was found that the elevated concentrations of reactive hydrocarbons co-emitted with nitrogen oxides from Hydrocarbon Processing facilities lead to substantial ozone production. South Pars...
متن کاملC1–C8 volatile organic compounds in the atmosphere of Hong Kong: Overview of atmospheric processing and source apportionment
We present measurements of C1–C8 volatile organic compounds (VOCs) at four sites ranging from urban to rural areas in Hong Kong from September 2002 to August 2003. A total of 248 ambient VOC samples were collected. As expected, the urban and sub-urban sites generally gave relatively high VOC levels. In contrast, the average VOC levels were the lowest in the rural area. In general, higher mixing...
