The relationship between the concentrations and distribution of organic pollutants and black carbon content in benthic sediments in the Gulf of Gdańsk, Baltic Sea

Organochlorine, Organophosphoric and Organotin Contaminants, Aromatic and Aliphatic Hydrocarbons and Heavy Metals in Sediments of the Ports from the Polish Part of the Vistula Lagoon (Baltic Sea)

“…The greatest amounts of PCBs in the sediments of the Gulf of Gdańsk were recorded in the Gdańsk Deep, the Bornholm Deep, and in ports. The concentration values ranged from several to several tens μg kg −1 dw (Sapota, 1997;Konat and Kowalewska, 2001;Sapota, 2006;Pazdro, 2007, Staniszewska et al, 2011. Comparable results were obtained during the present investigations in the Vistula Lagoon (Table 1, Figure 2).…”

“…In sediments of unpolluted areas that are under marginal anthropogenic pressure, concentrations of PAHs are less than several tens of μg kg −1 d.w. High concentrations of PAHs, ranging from several to several hundreds of mg kg −1 d.w., are recorded in sediments of ports, shipyards, and river mouths (Guz et al, 2000;Staniszewska et al, 2011).…”

Long-term seafloor monitoring at an open ocean aquaculture site in the western Gulf of Maine, USA: Development of an adaptive protocol

“…Regardless of the metric, sediment organic content is affected by factors other than organic pollutants (e.g., grain size; see discussion below) and the relationship between organic content and pollution loading is not straightforward. Even so, LOI values <5%, as was consistently found in the present study (Table 3) are substantially lower than that reported from ''enriched'' or ''polluted'' sediments in other areas (e.g., Grizzle and Penniman, 1991;Holmer and Kristensen, 1992;Staniszewska et al, 2011;Wilding et al, 2012a,b). It should be noted that 5% LOI was chosen in our protocol (Fig.…”

The relationship between the black carbon and bisphenol A in sea and river sediments (Southern Baltic)

“…It has been observed in several studies that BC plays a decisive role in the sorption of PAHs in sediments that are high in black carbon and low in organic carbon (Staniszewska et al, 2011). In sediments that are high in organic carbon, the predominant phenomenon may be that of organic matter competing against BPA for hole-filling in elemental carbon, which as a result weakens the sorptive abilities of BC in relation to BPA (Tian et al, 2009).…”
