This European Standard provides guidance on methods for sampling invertebrates in the hyporheic zone of wadable rivers. It describes each method, including details of the equipment involved and its use in the field. Guidance is given on developing a sampling strategy and selecting an appropriate survey technique for the purpose of investigation. NOTE Benthic macroinvertebrate sampling is covered by other published standards (see Bibliography). Selected literature with references in support of this document is given in the Bibliography.

EN ISO 18635:2016 水质测定短链烷烃(SCCP)沉积物中的多氯联苯,污水污泥和悬浮物(颗粒)用气相色谱-质谱法(GC-MS)和电子捕获负离子(ECNI)(ISO 18635:2016)
Diese Internationale Norm legt ein Verfahren zur quantitativen Bestimmung der Summe von kurzkettigen polychlorierten n-Alkanen fest. Diese werden auch als kurzkettige polychlorierte Paraffine (SCCP, en: short-chain polychlorinated paraffins) bezeichnet und haben Kohlenstoffkettenlängen von n-C10 bis einschließlich n-C13 in Gemischen mit Chlor-Massenanteilen ("Gehalten") zwischen 50 % und 67 %, die ungefähr 6000 der etwa 8000 Kongenere umfassen. Dieses Verfahren ist anwendbar auf die Bestimmung der Summe von SCCP in Sediment, Schwebstoff, Klärschlamm und Boden mittels Gaschromatographie-Massenspektrometrie mit Elektroneneinfang nach negativer chemischer Ionisation (GC-ECNI-MS). Abhängig von der Matrix und der Nachweisempfindlichkeit der GC-ECNI-MS kann das Verfahren auf Proben mit einer SCCP-Gesamtkonzentration von z. B. 0,03 µg/g bis 3 µg/g angewendet werden.
