We are UKAS accredited to analyse for dioxins
and PCBs in a wide variety of matrices including stack emissions,
soils, manufactured products and in food and feedstuffs. Dioxin
stack sampling equipment is also available for hire.
Dioxins and furans are the terms applied
to polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated
dibenzofurans (PCDFs). It is generally accepted that even
in minute amounts, these chemicals may cause cancer and birth
defects. Except for research and analytical purposes there
is no deliberate manufacture of these compounds. Rather they
appear as by-products of some chemical processes and from
inefficient incineration.
PCBs form another group of closely related
chemicals. A few exhibit toxicity similar to those of the
toxic dioxins and are therefore described as being dioxin
like.
The European Commission has recommended
a series of thresholds for dioxin content of food and feedstuffs.
Any measurements exceeding these thresholds should trigger
an investigation of possible contamination sources. This is
aimed at reducing dioxin exposure through food over the long
term to below the World Health Organisation (WHO) recommended
levels.
Envirolab will be happy to provide further
information regarding any aspect of dioxins in the environment
prior to any analytical work being undertaken. Advice on sampling
is also available and we have the expertise to explain any
aspect of the analytical process. Environmental contamination
with dioxins is still an emotive subject in terms of human
exposure through dietary or industrial emissions. Our service
is fast, reliable and client confidentiality is maintained
at all times.
