Dioxin-like toxicity of several PCNs.
For PCBs, there may be a special interest in determining dioxin-like PCBs.
The dioxin-like mechanism of toxicity of CNs is depending on the degree of chlorination.
CNs can contribute substantially to the TEQ of dioxin-like compounds in Arctic air.
Dioxin-like PCBs, PCDDs and PCDFs and non dioxin-like PCBs in human milk.
Based on biological activity, PCBs have been divided into non-dioxin-like and dioxin-like categories.
PCDD/Fs and dioxin-like PCBs are characterized by their semi-volatility and resistance to degradation.
Levels in solid residues were also low 1.7- 54 ug/kg for PCB and0.0018 ug TEQ/kg for PCDD/PCDF/dioxin-like PCBs.
Dioxin-like toxicity of air CNs in Ghana was estimated to range 0.49- 5.6 fg TEQ/m3 Hogarh et al., 2012b.
The levels of emissions of PCDD/PCDF/dioxin-like PCBs to air were very low, in the order of 0.00007 ng TEQ/m3N.
EN 1948(draft 2004)Stationary source emissions- determination of the mass concentration of PCDDs/PCDFs and dioxin-like PCBs.
CN levels found in the environment are high enough to induce dioxin-like cellular responses in feral fish as shown by empirical data.
CNs are proven to interact with the Ah receptor andtherefore can induce toxic effects typical for dioxin-like compounds.
As a result of LRTAP anddietary habits, human exposure to dioxin-like PCBs in many Arctic regions is considerably higher than in industrialized areas.
However, the calculated TEQ concentration in Rotander et al. was based on CN66 only anddid not include other dioxin-like compounds.
CNs show a dioxin-like mechanisms of toxicity thus contributing to the overall toxicity of dioxins and dioxin-like compounds such as coplanar PCBs.
They are detected in remote areas andcontribute a significant portion of the total dioxin-like activity in environmental samples.
Endocrine disrupting and dioxin-like activity have been shown to occur in cells treated with pentaBDE components and their primary metabolites.
CNs have been concluded to be potent foetotoxic andteratogenic agents producing effects similar to those for other toxic dioxin-like compounds.
The WHO TEF scheme also includes those PCB congeners which are considered to exhibit dioxin-like characteristics; their TEFs range from 0.1 down to 0.00001.
That I-TEF includes only the 17 PCDD and PCDFs congeners with chlorine atoms substituted in the 2, 3, 7 and 8 positions anddoes not include dioxin-like PCBs.
The general population is mainly exposed to PCDD/Fs and dioxin-like PCBs via common food items, particularly fatty food of animal origin e.g. meat, certain fish and dairy products.
Concentrations between 1- 8 pg/m3 have been found in the Arctic, where CNs can contribute substantially to the toxic equivalents(TEQ)presented by dioxin-like contaminants.
The Ministry developed an estimation of the mass concentration of PCDDs/PCDPs and dioxin-like PCBs, and technical rules on emission assessments of POPs to air, in cooperation with the National Academy of Sciences.
AHR binds several exogenous ligands such as natural plant flavonoids, polyphenolics and indoles,as well as synthetic polycyclic aromatic hydrocarbons and dioxin-like compounds.
Since the chemical andphysical properties of PCDD/Fs and dioxin-like PCBs make them susceptible to LRTAP, it is expected to contribute significantly to the exposure and health risks.
The general public, and in particular Arctic indigenous peoples, are exposed to CNs in addition to a wide array of other contaminants,including already regulated dioxin-like compounds such as PCBs, adding to the overall body burden.
In contrast CNs contribute significantly to the burden of dioxin-like compounds in Lake Ontario biota, contributing between 12 and 22% of total CN and PCB TEQ in lake trout and up to 69% in benthic organisms Helm et al. 2008.
One commercial plant, treating 0.25 kg/hour(as 100 per cent PCB) using supercritical water oxidation,had emissions to air of PCDD/PCDF/dioxin-like PCBs of 0.001- 0.002 ng TEQ/m3 and to water of 0.05 ng TEQ/L.
Surprisingly, the highest dioxin-like PCB, expressed as WHO98 TEQ, was found in milk samples from Ukraine, although marker PCB levels were several times lower than those in samples from the Czech Republic and Slovakia.
