Water quality - Determination of certain organochlorine insecticides, polychlorinated biphenyls and chlorobenzenes - Gas chromatographic method after liquid-liquid extraction (ISO 6468:1996)

Describes a method for determining certain organochlorine insecticides, polychlorinated biphenyls (PCBs) and chlorobenzenes (except the mono- and dichlorobenzenes) in drinking water, ground water, surface waters and waste waters. The method is applicable to samples containing up to 0,05 g/l of suspended solids.

Wasserbeschaffenheit - Bestimmung bestimmter Organochlorinsektizide, Polychlorbiphenyle und Chlorbenzole - Gaschromatographisches Verfahren nach Flüssig-Flüssig-Extraktion (ISO 6468:1996)

Diese Internationale Norm beschreibt ein Verfahren zur Bestimmung einiger Organochlorinsektizide, Polychlorbiphenyle (PCB) und Chlorbenzole (ausgenommen Mono- und Dichlorbenzole) in Trinkwasser, Grundwasser, Oberflächenwasser und Abwasser. Dieses Verfahren eignet sich für Proben, die bis zu 0,05 g/l suspendierte Stoffe enthalten; in Gegenwart von organischem Material, suspendierten Stoffen und Kolloiden treten häufiger Störungen auf, und die Nachweisgrenzen sind demzufolge höher.

Qualité de l'eau - Dosage de certains insecticides organochlorés des polychlorobiphényles et des chlorobenzènes - Méthode par chromatographie en phase gazeuse après extraction liquide-liquide (ISO 6468:1996)

La présente Norme internationale décrit une méthode pour le dosage de certains insecticides organochlorés, des polychlorobiphényles (PCB) et des chlorobenzènes (sauf le mono- et le dichlorobenzène) présents dans les eaux destinées à la consommation humaine, les eaux souterraines, les eaux de surface et les eaux usées. La méthode est applicable aux échantillons contenant jusqu'à 0,05 g/l de matières en suspension. En présence de matières organiques, de matières en suspension et de colloïdes, les interférences sont plus nombreuses et les limites de détection sont donc plus élevées. La méthode décrite dans la présente Norme internationale ne donne des informations que sur certains composés PCB spécifiques, et non sur le taux total de tous les composés PCB. Selon les types de composés à détecter et l'origine de l'eau, les limites de détection indiquées au tableau 1 sont applicables pour la méthode décrite dans la présente Norme internationale, pour des eaux à faible teneur organique. Compte tenu des très faibles concentrations habituellement présentes dans les eaux, le problème de la contamination est particulièrement important. Plus le niveau mesuré est faible, plus il faut prendre de précautions et tout particulièrement lorsque les concentrations sont inférieures à 10 ng/l.

Foreword
IS0 (the International Organization for Standardization) is a worldwide fed-
eration of national standards bodies IS0 member bodies). The work of
(
preparing International Standards is normally carried out through IS0
technical committees. Each member t: N )dy interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. IS0 collab-
orates closely with the International Electrotechnical Commission (IEC) on
all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are cir-
culated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 6468 was prepared by Technical Committee
lSO/TC 147, Water quality, Subcommittee SC 2, Physical, chemical, bio-
chemical methods.
Annex A forms an integral part of this International Standard. Annexes B to
H are for information only.
