“…Fifty six inter-tidal sampling sites were accessed by Port of London Authority Dory attached to the vessel Driftwood II, using pre-determined GPS co-ordinates to accurately locate each position (sites 1-56). At each site, clear polycarbonate tubes (140 cm length Â 6 cm I.D) fitted with a stainless steel basket catcher at the base were manually driven into the exposed sediment and extracted to recover the core material (Vane et al 2007(Vane et al , 2013. Upon collection, sediment cores were stored frozen at À18 C in the dark to avoid post-collection chemical changes and physical movement; then transported frozen to the laboratory within three days.…”

Fifty six sediment cores were collected along a 100 km longitudinal transect of the Thames estuary. Total Hg ranged from 0.01 to 12.07 mg/kg, with a mean of 2.10 mg/kg (n ¼ 351). Concentrations of the toxic metal decreased downstream from London to the outer estuary and were positively correlated to total organic carbon (TOC) content. Many Hg profiles showed a clear rise, peak and fall, reflecting changing anthropogenic input through time. Surface concentrations averaged 1.27 mg/kg, confirming the effectiveness of recent environmental legislation and improved river management. Sediments at >40 cm depth from London reaches of the river (Waterloo Bridge, Cuckolds Point (Rotherhithe), Butlers Wharf (Tower Bridge), Millwall, Deptford and Millennium Dome) were highly contaminated, with levels of Hg of >7 mg/kg. The outer Thames had lower Hg, with the exception of Rainham, Crossness and Cliffe. Benchmarking against UK guidelines for the disposal of dredged material revealed that 88 samples from 21 sites exceeded the 3 mg/kg criteria (unsuitable for disposal at sea); 173 fell between 0.3 and 3 mg/kg (further assessment required); and 90 were of no concern. Using Hg as a generic pollution marker, the tidal Thames is one of the world's most contaminated river-estuarine sediment systems.

“…At the same time, allowing for the high variability of absolute PAH concentrations in residual peat horizons, it could be surmised that they tend to accumulate 5-6-nuclear compounds, which could indicate processes of peat combustion. Vane et al (2013) also pointed out the presence of lowand high-molecular PAHs in soils after peat fire. However, 5-6-nuclear compounds (benz(ghi)perylene, benz(a)pyrene, benz(e)pyrene, benz(k)fluotanthene) could be considered the indication group marking the peat combustion.…”

“…Vane et al (2013) note that PAH concentrations in peat soils after fire are lower than the amount dangerous for biota. Also, there is no evidence that amounts of PAHs accumulated after the fire are dangerous to humans, as they are lower than hazardous levels determined for soils, but the variation of high-molecular-weight PAHs in soil horizons was high, as these compounds do not occur in all horizons, and their formation is a more complicated process in comparison with low-molecular PAHs.…”

“…It was shown that PAHs accumulated in these soils in small amounts and posed no danger to humans. However, PAH accumulation in soils after smoldering fires causing deep changes in soil profiles was investigated insufficiently (Vane et al, 2013;Gennadiev and Tsibart, 2013;Bojakowska and Sokołowska, 2003).…”

“…Peat smoke also contains sulfur, potassium, oxides of nitrogen (Blake et al, 2009) and metals (Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Ti, V, Zn) (Betha et al, 2013). PAHs are part of the peat combustion products in most cases and, after the fires, they generally accumulate across the whole soil profile (Vane et al, 2013;Kakareka et al, 2004;Blake et al, 2009). So, PAHs can accumulate in situ in char and ash layers before they are released into the atmosphere (Rein, 2013).…”

Polycyclic aromatic hydrocarbons in post-fire soils of drained peatlands in western Meshchera (Moscow region, Russia)

Abstract. Polycyclic aromatic hydrocarbons (PAHs) are priority pollutants that arrive in the environment from numerous anthropogenic and natural sources, but the data on their natural sources including wildfires remain insufficient. The level of contamination and the composition of PAHs in soils of the areas affected by wildfires were studied in this work. The study was conducted in the Moscow region (Russia) in areas occupied by drained peatland and strongly damaged by fires in 2002, 2010 and 2012. The features of PAH accumulation and the profile distributions in histosols and histic podzols after the fires of different times were analyzed. It was shown that new soil horizons formed after the fires -Cpir, Hpir and incipient O horizons -and that these horizons differ in PAH accumulation rate. Maximal total concentrations of 14 PAHs were detected in charred peat horizons Hpir (up to 330 ng g −1 ) and in postfire incipient O horizons (up to 180 ng g −1 ), but the highmolecular-weight PAHs (benz(ghi)perylene, benz(a)pyrene, benz(k)fluoranthene) were revealed only in charry peat horizons. The trends of higher PAH concentrations were found in cases when smoldering combustion resulted in rather thick residual peat horizons. In cases of almost complete pyrogenic destruction of He horizons, total PAH concentrations were no more than 50 ng g −1 . Also, PAH accumulation in upper horizons of soils near the sites of the latest fires was observed.
