“…In order to exclude a possible thermal phase transition of chrysotile fibres, thermogravimetric analysis has been performed. The TG-DTG curves of chrysotile fibres, display a first endothermic thermal process between 600°C and 700°C, due to transformation to metachrysotile (Mg 3 (OH) 4 Si 2 O 5 → Mg 3 Si 2 O 5 +2H 2 O) and a second one, exothermic at 825°C, that corresponds to the crystallization of forsterite in agreement with literature data [15,16].…”

A new analytical method for the determination of low levels (0.01-1 wt%) of free fibres of chrysotile in contaminated clayey, sandy and sandy-organic soils is described. The detection limit of 0.01 wt% is reached with an enrichment of free fibres of chrysotile in the sample using a standard laboratory elutriator for sedimentation analysis. The chrysotile quantitative determination is performed both by X-ray powder diffraction, using the internal standard and reference intensity ratio methods, and by Fourier-transform infrared absorption spectroscopy. The procedure can be successfully applied to different soils after removal, by a thermal treatment, of the matrix components which can interfere. This straightforward method fulfils the request of public institutions and private companies for an appropriate quantitative determination of chrysotile-free fibres in contaminated soils.

The risks associated with, geographic locations of, and engagement strategies required by exploration companies have shifted in the last 25 years, largely in response to changing public attitudes and governance approaches. A mixture of growing global environmental consciousness, the rise of international civil society networks, and economic liberalization and government deregulation in the developing world have all played key roles in altering the environment for mineral exploration. Three fundamental tenets of a positive climate for exploration have been altered: access to land, ease and speed of permitting, and the right to mine deposits after discovery. This paper identifies the importance of new stakeholders, including nongovernmental organizations, international financial institutions, and community activist networks; new governance approaches, such as self-regulation, the use of international standards and co-management, and new monitoring and engagement techniques, such as environmental and social impact assessment, thirdparty monitoring, and prior informed consent. The traditional relationship focus between states and corporations has been replaced by constantly evolving relationships among corporations, governments, civil society, and affected communities. Exploration companies, particularly junior companies, must use available tools—early community engagement strategies and available guidance documents from industry associations among them—to adapt themselves to this new focus.
