Identifikace azbestových vláken v technických produktech a stavebních materiálech na SEM je založena na německém

INGENEURE

Metoda je vhodná pro identifikaci azbestových vláken, jejichž hmotnostní obsah je vyšší než 1%.

Prachový vzorek se zpracovává při zvětšení v rozsahu 100 až 5000krát.

Nalezená minerální vlákna nebo svazky vláken jsou podrobeny

EDS analýze (EDXA) a na základě elementárního složení a rovněž i morfologie vlákna je analyzovaný objekt jednoznačně

identifikován.

Further research is needed to better understand health risks associated with exposure to other

thoracic-size elongate mineral particles (EMPs), including those with mineralogical compositions identical or similar to the asbestos minerals and

those that have already been documented to cause asbestos-like disease, as well as the

physicochemical characteristics that determine their toxicity.

Problematika syntetických minerálních vláken

Jsou předmětem toxikologických studií a musí splňovat podmínku biodegradibility – v EU pouze v Německu mají podrobně rozpracovány nutné podmínky pro použití těchto minerálních vláken za účelem tepelné a zvukové izolace. Musí splňovat alespoň jednu ze tří podmínek (TRGS 905):

I. Vhodný intraperitoneální test nesmí prokázat znaky výrazné karcinogenity.

II. Poločas clearance po intratracheální instilaci 2mg respirabilních vláken ve formě suspenze musí být menší nebo roven 40-ti dnům.

III. Index karcinogenity (KI) definovaný vzorcem:

KI = Σ(Na2O, K2O, B2O3, CaO, MgO, BaO) – 2 x Al2O3

musí být roven nebo větší 40.
