Dental Bio Aerosols – Ignored Occupational Hazard | Chapter 01 | Theory and Applications of Microbiology and Biotechnology Vol. 1

An aerosol is a suspension of solid or liquid particles in air or other gaseous environment. Sources of bacterial aerosols exist within and outside the dental clinic. The generation of bacterial aerosols and splatters appears to be highest during dental procedures. The use of rotary dental and surgical instruments and air-water syringes generates visible infectious spray, that enclose large-particle spatter of water, saliva, microorganisms, blood, and other debris. Several infectious diseases could be transmitted to staff and patients by airborne bacterial and other contaminants in the dental clinic. The vigilant use of barriers along with appropriate immunizations procedures could safe guard the dental fraternity from the ill-effects of the aerosols.

Further Evidence of Coal Fly Ash Utilization in Tropospheric Geoengineering: Implications on Human and Environmental Health | Chapter 11 | Current Perspectives to Environment and Climate Change Vol. 1

We disclose a fourth independent line of evidence, based on the co-precipitation technique, pointing to coal fly ash as the material utilized in tropospheric geoengineering, and describe some of the adverse environmental and public health risks associated with its persistent application. During a snow storm, the fluffy snow traps geoengineering-aerosol-particulates and brings them down with the snow. The results of the ICP-MS analytical measurements of the snow-melt particulates we tested are consistent with three independent lines of evidence that coal fly ash is the main aerosolized particulate used for tropospheric geoengineering. Coal fly ash tropospheric geoengineering inhibits rainfall to change weather/climate which disrupts habitats, including arable habitats. Long periods of artificially induced drought can wreak economic disaster on farmers, and shift the delicate balance in nature, weakening natural defenses and giving a boost to aggressive pathogens. Coal fly ash when exposed to water or body fluids can release a host of toxic chemicals including neuro-toxic aluminum in a chemically mobile form and carcinogens such as arsenic, hexavalent chromium, and the radioactive elements, uranium, thorium and their daughter products. The only safe geoengineering is no geoengineering at all.
