PCDDs and PCDFs in soil and river sediment samples from a rural area in the United States of America

Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in water and suspended particulate matter from the Xijiang River, China

“…Therefore, most of soils and sediments show similar pattern. Similar congener profiles were reported for sediment samples from Mississippi, USA [21] and from Hong Kong [22]. Similarly, soil samples from Guangzhou [23] and Hong Kong's New Territories [4] also contained this "OCDD abnormality".…”

PCDD/Fs in sediments of Central Vietnam coastal lagoons: In search of TCDD

“…In Fig. 2, the reference data are grouped into: (i) contaminated areas (e.g., Miyata et al, 1995;Pieper et al, 1997;Rappe et al, 1997;Bellucci et al, 2000); (ii) coastal areas (e.g., Tyler and Millward, 1996;Dannenberg et al, 1997;Fattore et al, 1997;Koistinen et al, 1997;Wade et al, 1997;Müller et al, 1999Müller et al, , 2002Bellucci et al, 2000;Sakurai et al, 2000;Gaus et al, 2001;Sericano et al, 2001;Dalla Valle et al, 2003;Naito et al, 2003;Koh et al, 2004;Okumura et al, 2004;Eljarrat et al, 2005;Hu et al, 2005;Danis et al, 2006;Suarez et al, 2006); and (iii) internal waters (e.g., Gifford et al 1996;Rose and McKay, 1996;Schramm et al, 1997;Vartiainen et al, 1997;Isosaari et al, 2002;Ryoo et al, 2005). This accounts for generally low inputs, even if it seemed reasonable to expect higher concentrations of TCDD from the use of Agent Orange.…”

Patterns and sources of PCDD/Fs and dioxin-like PCBs in surface sediments from the East River, China

“…To date, the sources of the elevated OCDD in sediments and soils from Hong Kong [30], Mississippi [15] and a range of other sites remain unclear. But some evidences indicate there were some nonanthropogenic sources.…”
