The report summarises the monitoring activities within the National Swedish Contaminant Programme for freshwater biota. Each monitored contaminant has been examined in pike, perch and Arctic char from 32 lakes from the north to the south in Sweden.
No general trend could be seen for mercury, and all samples, except Arctic char from Abiskojaure, were above the EU target level. Lead was generally decreasing. Nickel showed a general upward trend in perch. An increase, or indication of an increase, was seen for chromium during the last ten years. Zinc concentrations were decreasing in a majority of the perch samples and in pike from Lake Storvindeln. No general trend was observed for copper, arsenic, silver, aluminum, tin, bismuth, and cadmium. But 30% of the perch samples were above the target level for cadmium.
In general, downward trends were seen for; PCBs, HCHs, DDT, DDE and PCDD/Fs in all species (with a few exceptions). The chlorinated compounds generally show a somewhat higher concentration in the southern parts of Sweden. Most chlorinated compounds were below the suggested target levels.
No general trend was seen during the monitoring period for PBDEs. Concentrations of PBDEs in Lake Bolmen increased from the 60s and peaked in the late 80s to mid-90s and have subsequently decreased. The concentration of HBCDD was under LOQ in a majority of the samples.
A majority of the perfluorinated compounds showed an increase in concentration in perch, except PFOS and FOSA. Higher concentrations of perfluorinated compounds can in general be seen in the southern part of Sweden.

Decabromodiphenyl ethane and decabromodiphenyl ether in Swedish background air

2012 | Chemosphere | 86 (264-269)

Decabromodiphenyl ethane (DPDPE) is a flame retardant that has been on the market for more than 20 years and is used as a replacement for decabromodiphenyl ether (BDE-209). Environmental data on DPDPE are scarce but for BDE-209, studies have shown that long-range transport in the atmosphere leads to contamination of remote regions. Given their similar physical-chemical properties, we hypothesized that this is also true for DPDPE. In this study we explored the European continent as a source for DBDPE by collecting air samples at a back-ground location in southern Sweden. Twelve samples with stable air mass back trajectories over the 24 h sampling period were analysed. BDE-209 and 5 polycyclic aromatic hydrocarbons (PAHs) were also included in the study. The concentration ranges of DBDPE and BDE-209 were similar, 0.077-7.9 and 0.093-1.8 pg m-3 air, respectively. The highest concentrations were detected when the air originated from the European continent and the lowest during perods with rather stagnant air over southern Scandinavia. The concentrations of DBDPE and BDE-209 did not co-vary, indicating that there are different major sources of the two compounds. In air, the compunds measured in this study are predominantly associated with particles. PAHs in the atmosphere are known to originate primarily from combustion processes and their concentrations were highly correlated with several measures of atmospheric particle concentration, i.e. PM 10, PM 2.5, soot, and N 450 (number of particles in the size range approximatly 420-450 nm). No clear correlations were found between the concentrations of DBDPE or BDE-209 and any of the measures of particle concentrations, indicating that the emissions of these are not related to the major sources of emissions of soot or small particles.
