‘engineered nanomaterial’ means any intentionally produced material that has one or more dimensions of the order of 100 nm or less or that is composed of discrete functional parts, either internally or at the surface, many of which have one or more dimensions of the order of 100 nm or less, including structures, agglomerates or aggregates, which may have a size above the order of 100 nm but retain properties that are characteristic of the nanoscale.
ciallaíonn “nana–ábhar a ndearnadh innealtóireacht air” aon ábhar a tháirgtear d’aon ghnó ag a bhfuil toise amháin nó níos mó de thimpeall is 100 nm nó níos lú, nó ar ábhar é atá comhdhéanta de chodanna feidhmiúla scoite, bíodh siad sa mhianach ann nó ar an dromchla, ar codanna go leor acu nach mó ná 100 nm ceann amháin nó níos mó dá dtoisí, lena n–áirítear struchtúir, ceirtleáin nó tathaguithe, a bhféadfaidh méid níos mó ná 100 nm a bheith acu ach a bhfuil airíonna fós acu ar saintréithe den nanascála iad.
