(c) Environmental fate (provide summary information and relevant references)
Chemical/physical
properties
Persistence
How are
chemical/physical
properties and
persistence linked to
environmental transport,
transfer within and
between environmental
compartments,
degradation and
transformation to other
chemicals?
Bio-concentration or bioaccumulation factor,
based on measured
values (unless
monitoring data are
judged to meet this need)
(d) Monitoring data (provide summary information and relevant references)
The Ministry of the Environment, Japan, has monitored Pentachlorobenzene in several media since FY
1975. In FY 1975 and 1979, it surveyed 100 and 111 water specimens, respectively, across the country. and
PentaCB was not detected with the detection limit of 10 and 2-40 ng/L.
It also surveyed bottom sediment specimens in FY 1975 and 1979. In FY 1975, 100 specimens were
surveyed across the country, but no Pentachlorobenzene was detected with the detection limit of 10 ng/gdry. In contrast, 111 specimens were surveyed in FY 1979 and detected PeCB in 30 specimens with
improved detection limit of 0.01-10 ng/g-dry. The concentration was between 0.1 and 11 ng/g-dry.
It has surveyed specimens of fish across the country since FY 1974. The survey on 95 fish specimens in FY
1975 shows that Pentachlorobenzene was detected in 3 specimens in the range of 18-88 ng/g-wet with the
detection limit of 10 ng/g-wet. It additionally surveyed in FY 1979 on the same scale of fish shows that
Lindane was detected in 3 specimens with the improved detection limit of 0.01 ng/g-wet. The concentration
was 1 to 2 ng/g-wet.
It also surveyed, in FY 1994 and 1999, 24 and 39 specimens, respectively, in Japan for ambient air. It
detected Pentachlorobenzene in 9 specimens with the detection limit of 1 ng/m3, and the concentration was
1.0-8.0 ng/m3. In FY 1999, Pentachlorobenzene was detected in all the specimens and the concentration of
Pentachlorobenzene was 0.012-1.1.
