“…Ishiwatari and Matsushita (1986) showed that the amount of perylene in sediment samples increased significantly as a result of reduction of perylenequinone with zinc dust. These results suggest that the precursor of perylene has a terrestrial origin, including both plants and parasitic fungi (Aizenshtat, 1973;Ishiwatari et al, 1980;Jiang et al, 2000;Bechtel et al, 2007;Jiang and Liu, 2008). However, Wakeham et al (1979) detected abundant perylene in the Namibian Shelf (0.17-0.82 µg g -1 ), where the input of terrigenous material is negligible, and precursors such as perylenequinone might not be associated with terrigenous material.…”

“…transformed into perylene by removal of oxygen and aromatization under anaerobic conditions (Ishiwatari and Matsushita, 1986;Jiang et al, 2000). Sato and Kumada extracted perylenequinone from podzolic soils and showed that it can be reduced with zinc dust (Sato and Kumada, 1967;Sato, 1976c).…”

“…The latter are the higher condensed PAHs FLA, PYR, BAA, CHR, BBJK, BEP, BAP, IND and BGHI, which are mainly of pyrogenic origin (Hwang et al, 2003). The five ring PAH perylene is not considered as a combustion PAH as it is not thermally stable (Jiang et al, 2000).…”

“…Perylene is not present or occurs only in small amount in the products of combustion processes, probably due to its thermal instability or reactivity (Jiang et al, 2000), but there is also significant evidence that it can be produced biologically under anaerobic conditions (Venkatesan, 1988;Thiele and Brümmer, 2002). Perylene quinones (pigments found in several insects, plants or fungi) are suspected to be degraded to perylene by anaerobic microbial metabolism (Jiang et al, 2000;Wilcke et al, 2002).…”

Kathmandu, the capital of Nepal, faces increasing environmental problems such as heavy air pollution and lack of proper waste management. The aim of this study was to examine if the soils are also affected by pollution, with the focus on polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs). The sum of 20 PAHs in surface soils ranged between 184 and 10279 lg kg À1 . The most abundant PAHs were perylene (14.6%), benzo(b+j+k)flouranthene (10.7%), naphthalene (10.7%) and phenanthrene (9.8%), with perylene concentrations varying strongly. The significantly more positive d 13 C values of perylene in samples with elevated concentrations indicate biological production, possibly by anaerobic degradation of perylene quinones. PAH ratios also indicate the influence of petrogenic PAH sources, especially at petrol stations and some street samples. The sum of 12 PCBs ranged from 356 to 44710 ng kg À1 . The most abundant were congeners 52 (19.4%), 101 (14.3%), 118 (13.4%) and 138 (11.7%). The low PCB concentrations and pattern were interpreted as a diffuse background contamination being the main PCB source in the urban soils. Indications for recent contamination were found in river sediments from the inner city, as well as in industrial and street samples. Classified by land use, the samples taken from the gutter contained the highest PAH and PCB concentrations as a result of accumulation. The lowest values were found in surface soils from Swayambunath (a park) and a garden area. A gradual decrease in concentration with depth was present for both compound classes in the profiles sampled at Swayambunath. No trend was visible in the garden profiles as a result of soil disturbance of the soil by agricultural treatment. Enhanced microbial degradation and volatilization in the warm/humid monsoon climate is probably the main cause for low pollutant concentrations. Increased photodegradation and the short accumulation period might be other important factors. Concerning its state of soil pollution, Kathmandu fits rather well into a global distribution pattern of persistent organic pollutants, with high concentrations in temperate (higher latitude) regions and very low ones in the tropics (lower latitude regions) due to global distillation.
