In the last few decades, non-occupational asbestos-related diseases have been documented in populations living near naturally occurring asbestos (NOA) sites, including regions in Greece, Cyprus, China, New Caledonia, Turkey, and Italy. This highlights the critical need to assess geological and environmental hazards associated with NOA. Fibrous antigorite, among the >400 naturally occurring fibrous minerals, has emerged as a potential health and environmental hazard.

- Naturally Occurring Asbestos (NOA) is linked to higher rates of malignant mesothelioma in populations near NOA sites, particularly in specific villages in the Basilicata region of South Italy, which are at high risk of asbestos exposure due to their geological context.
- A detailed study of an asbestos tremolite sample from the Iacolinei quarry revealed that it contains long fibers, with a significant portion being highly reactive and biologically active, raising concerns about its potential health hazards.
- The presence of iron in the asbestos structure is noted to enhance toxicity, categorizing the tremolite as a potent carcinogen and prompting ongoing investigations into its environmental impact for public health safety.
Dissolution Reaction and Surface Modification of UICC Amosite in Mimicked Gamble's Solution: A Step towards Filling the Gap between Asbestos Toxicity and Its Crystal Chemical Features.

November 2023
Article Synopsis
- The study examines how amosite asbestos fibers dissolve when exposed to a synthetic solution that replicates body conditions, focusing on a specific pH and temperature over an extended period.
- Researchers used various analytical methods to compare the dissolution behavior of amosite to other asbestos types (tremolite and crocidolite), finding similar incongruent dissolution patterns and a preferential release of magnesium and calcium ions.
- Interestingly, no iron was detected as being released from amosite fibers, which suggests unique stability traits, and highlights the importance of understanding these chemical changes for assessing the long-term toxicity related to asbestos materials.
Article Synopsis
- The environmental impact of natural occurrences of asbestos (NOA) is a rising concern, but inconsistent sampling and analytical methods complicate the issue.
- A multidisciplinary approach involving geology, chemistry, and toxicology is suggested to assess the hazards posed by NOA, specifically focusing on antigorite found in Varenna Valley, Italy.
- Findings indicate that antigorite has a toxicity profile and bioactivity potentially comparable to chrysotile asbestos, highlighting the need for careful hazard assessment of NOA sites.
Polycrystalline wools (PCW) are included with Refractory ceramic fibers (RCF) in the alumino-silicates family of High Temperature Insulation Wools (HTIW). IARC includes PCW in the ceramic fibers group and considers them as possible human carcinogens (GROUP 2B). Since PCW toxicity is not yet clear, our aim was to evaluate their toxic and inflammatory effects and to compare them with the known RCF effects.
