متن کاملCanaries in the coal mine.
Up until 30 years ago, coalminers relied on canaries as warning systems against harmful gases and pollutants underground. The miners listened for birdsong and if the birds fell silent, then they knew there was danger to their health and to take action. Today we have much more sophisticated information and reporting on the quality of air. We know precisely the levels and composition of pollutant...
متن کاملMeasurement of Individual Radon Progeny in Egyptian Under Ground Coal Mine and Related Lung Doses
Some trace elements in coal are naturally radioactive. These radioactive elements include uranium (U), thorium (Th) and their numerous decay products, including radium (Ra) and radon (Rn). So, the staff of underground coal mine can be exposed to Rn and its progeny (Po, Pb and Po). The present study has been done in El-Maghhara mine. It is located in the middle of Sinai desert about 250 km north...
متن کاملA review of acidity generation and consumption in acidic coal mine lakes and their watersheds.
Lakes developing in former coal mine pits are often characterized by high concentrations of sulfate and iron and low pH. The review focuses on the causes for and fate of acidity in these lakes and their watersheds. Acidification is primarily caused by the generation of ferrous iron bearing and mineralized groundwater, transport through the groundwater-surface water interface, and subsequent iro...
متن کاملHigh-tech coal mine canary.
High-tech coal mine canary One of coal mining's earliest systems for warning of the presence of methane gas, the canary in the coal mine, though low-tech, was extremely effective and rather easy to read: if the bird died, miners had to get out of the shaft. Today, the search for means to monitor for signs of danger continues. At an annual checkup, one could be given a whole battery of tests, ea...
