February 2008 - This report compiles information
about and assesses the environmental impact
of the former lead-zinc mine at Mestersvig
to document the present state of the environment
in areas affected by the mining operation
1956-1963. The report has been prepared
on the request by International Molybdenum
PLC (InterMoly), who is exploring the molybdenum
deposit at Malmbjerget to the south of Mestersvig.
The report documents
that the former mine has caused a significant
pollution with lead and zinc on land, in
the river Tunnelelv and in Kong Oscars Fjord.
Mine tailings and spill of concentrate are
the main pollution sources. The area surrounding
the mine site has been monitored since 1979
demonstrating that both lead and zinc concentrations
have decreased in the media monitored: sediments,
seaweed and fish. However, Kong Oscars Fjord
will be affected by heavy metal pollution
for many years.

Control of Pesticides
2006. Chemical Substances and Chemical Preparations
6 February 2008 - Four
different groups of products covered by
the pesticide regulation were included in
the 2006 analytical chemical authority control:
Herbicides containing metamitron, propaquizafop
and haloxyfop-ethoxyethyl.
Fungicides containing azoxystrobin, propiconazole,
cyprodinil, picoxystrobin and fenpropidin.
Insecticides containing pirimicarb.
Plant growth regulators containing chlormequat
chloride, mepiquat chloride and ethephon.
All samples were examined for the content
of active ingredients and for the content
of OPEO and NPEO.
All samples in this
years programme complied with the accepted
tolerance limits with respect to the content
of the active ingredient as specified in
Danish Statutory Order on pesticides. None
of the examined samples contained OPEO,
but one of the samples contained minor concentrations
of NPEO. On the label of two products, the
content of active ingredient was declared
only in g/L, but not in % (w/w) as required
and on one product the labelled content
given in % was not in accordance with the
labelled content given in g/L.
