Brief concise description explaining the innovation
A gyökérnövekedés-gátlás mérési módszere alkalmas a szennyezőanyagok talajflórára gyakorolt hatásának meghatározására. A szennyezett talajminta toxicitása a gyökérhossz változásával arányos.
Typical (recommended) application of the method
talaj toxicitásának vizsgálata, talajra helyzedndő hullaldék tesztelése, csurgalékok tesztelés
Limits of the method
munkaigényes

Important findings, points of interest, remarks
A gyökérnövekedést a szennyezettségen kívül más körülmények is befolyásolják.
Nem oldott, hanem pl. szemcsés szennyezettség a gyökér megnyúlását eredményezheti (a gyökér kikerüli a szennyezett szemcsét)
