Scientists say that there is genuine debate on that point, but that by an overwhelming number, studies on asbestos exposure have found the larger particles to be far more dangerous because they tend to embed themselves in lung issue.
Dr Ana Valdes, Reader at the University of Nottingham and co-author of the study, said: "Our work builds on a number studies exploring whether some vitamins can counteract the negative effect on lungs caused by air pollution".
The membranes were subjected to X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric (TG), differential scanning calorimetry (DSC), tensile, impedance spectroscopy, compatibility and transport number studies.
Differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), complex impedance spectroscopy, ionic transference number studies, linear sweep voltammetry (LSV) and cyclic voltammetry (CV) studies exhibit promising characteristics of prepared GPEs for suitable application in LPBs.
A large number studies have confirmed that glass particles will not generate deleterious expansion themselves once they are smaller than 300μ (Meyer and Baxter 1997; Shi et al. 2004).
A number studies were conducted to determine potential sites for groundwater exploration in diverse geological set-ups using remote sensing and GIS techniques (Krishnamorthy and Srinivas 1995; Nas and Berktay 2010).
