This International Standard describes a method for
determining certain organochlorine insecticides, polychlorinated
biphenyls (PCBs) and chlorobenzenes
(except the mono- and dichlorobenzenes) in drinking
waters, ground waters, surface waters and waste
waters.
The method is applicable to samples containing up to
0,05 g/l of suspended solids. In the presence of organic
matter, suspended matter and colloids, interferences
are more numerous and consequently the
detection limits are higher.
The method described in this International Standard
only gives information on specific PCB compounds but
no information on the level of total PCBs.
According to the types of compounds to be detected
and the source of the water, the detection limits given
in table 1 are applicable for the method described in
this International Standard, with waters of low organic
contents.
Given the very low concentrations normally present in
the waters, the problem of contamination is extremely
important. The lower the level measured, the more
precautions have to be observed; below concentrations
of 10 rig/l,, special care is necessary.
