92. Calls for the Commission, when coming forward with legislation on hydraulic fracturing, to include a mandatory environmental impact assessment for both the exploration and extraction of shale gas; stresses, moreover, that there is insufficient data on the chemicals used in the hydraulic fracturing process; calls on the Commission, therefore, when coming forward with such legislation, to ensure transparency as regards all data on these chemicals in order to secure the highest possible level of public health and environmental prot ...[+++]ection;

2. Stresses that unconventional shale gas mining may pose serious risks with regard to water contamination caused by the use of hazardous chemicals in the fracturing process; is also concerned at the high amount of water used for the fracturing of fluid and at the potentially high emissions of methane, among other things;

(Return tabled) Question No. 152 Ms. Kirsty Duncan: With respect to the development of unconventional gas resources, including shale, tight and coal bed methane, and its possible impacts on the environment: (a) what, if any, research has the government undertaken regarding the development of unconventional gas resources, (i) what was the scope of this research in the areas of, but not limited to, air quality, aquatic and terrestrial ecosystem impacts, economic impacts, occupational risks, public safety concerns, and seismic risks, (ii) what, if any, resources did the government provide for this research, (iii) what, if any, process was e ...[+++]stablished to ensure the independence of the researchers, their research, and their findings, (iv) what, if any, case studies were considered as a part of this research, (v) what, if any, scenarios regarding the development of unconventional gas resources were developed as frameworks for the research, (vi) what economic, environmental and social impacts were identified by this research, (vii) what, if any, priority research areas were identified for further study as a result of this research, (viii) what, if any, departments were involved in this research, (ix) what, if any, action was undertaken to ensure inter-departmental cooperation throughout the research process, (x) what, if any, gaps or weaknesses in the regulatory framework did the research identify; (b) what, if any, research has the government undertaken regarding balancing shale gas' potential contribution to energy security with environmental risks; (c) what are the sources of greenhouse gas emissions associated with unconventional gas; (d) has the government developed a process to determine the overall carbon footprint of shale gas throughout the life cycle of natural gas use, if not, why not, and, if so, (i) what federal departments are involved in this process, (ii) how does the government ensure inter-departmental collaboration on this process, (iii) what is the p ...

As concerns the technical characteristics, the investigation demonstrated that ductile cast iron, in contrast to grey cast iron, has technical properties that allow the material to resist higher rupture stress and, more importantly, to be deformed to a significantly higher extent under compressive stress without fracture, i.e. ductile cast iron possesses plastic ductility whereas grey cast iron breaks under compressive stress, i.e. is brittle.

This condition not only greatly affects patient autonomy, but also creates very stressful situations in the families of hip fracture victims.

From a public health point of view, there were numerous cases of fractures, respiratory infections due to flu, exhaustion and depression caused by stress.
