Soil quality - Plant-based test to assess the environmental bioavailability of trace elements to plants (ISO 16198:2015)

ISO 16198:2015 specifies the plant-based test, called biotest, which enables estimation of the environmental bioavailability of trace elements to plants either basically as the concentration in shoots and roots or in a more integrative way as the net uptake flux in plants.

Qualité du sol - Test végétal pour l'évaluation de la biodisponibilité environnementale des éléments traces pour les végétaux (ISO 16198:2015)

L'ISO 16198:2015 spécifie le test végétal, dénommé «biotest» qui permet d'estimer la biodisponibilité environnementale des éléments traces pour les végétaux, soit simplement sous la forme de concentrations dans les parties aériennes et racinaires, soit de façon plus globale sous forme de flux de prélèvement net dans les végétaux.

Kakovost tal - Rastlinski biološki preskus za ocenjevanje okoljske biološke razpoložljivosti elementov v sledovih za rastline (ISO 16198:2015)

Preskus na rastlinski osnovi, v nadaljevanju biološki preskus, je preskus za ocenjevanje okoljske biološke razpoložljivosti elementov v sledovih za rastline kot vsebnost v poganjkih in koreninah ali na bolj celostni način kot neto absorpcija v rastlinah. Postopek biološkega preskusa zajema dva zaporedna koraka: (i) predhodna hidroponična rast in (ii) rast v stiku z vzorci prsti. Vsebnost elementov v sledovih v poganjkih in koreninah kot tudi njihova neto absorpcija v rastlinah se določata po koncu drugega koraka biološkega preskusa. Biološki preskus se uporablja za ocenjevanje okoljske biološke razpoložljivosti elementov v sledovih za rastline, bolj natančno poljščine, ki rastejo v prsti ali talnih materialih s prisotnostjo kisika, ob upoštevanju naslednjih alinej:
– tri rastlinske vrste (zelje, Brassica oleracea; trsikasta bilnica, Festuca arundinacea; paradižnik, Lycopersicon esculentum; glej 7.1) so predlagane v standardiziranih postopkih bioloških preskusov, uporabiti pa je mogoče tudi druge ciljne rastlinske vrste (glej dodatek A); – standardizirani postopek biološkega preskusa je potrjen za več elementov v sledovih, vključno z arzenikom (As), kadmijem (Cd), kromom (Cr), bakrom (Cu), svincem (Pb), nikljem (Ni) in cinkom (Zn), vendar so mogoči tudi drugi elementi v sledovih (glej dodatek A); – uporaba tega biološkega preskusa za prsti in talne materiale vključuje prsti, pred ali po vzorčenju polja, spremenjene s kompostom, blatom, odpadnimi vodami in drugimi (odpadnimi) materiali.
