1.0 INTRODUCTION Flame photometry‚ also referred to as ’flame atomic emission spectrometry ’ is a quick‚ economical and simple way of detecting traces of metal ions‚ primarily Sodium‚ Potassium‚ Lithium‚ Calcium‚ and Barium‚ in a concentrated solution. The process is an extension of the principles used in a flame test‚ with the main differences having more precision in the results‚ and the use of more advanced technology. This report focuses on the theory‚ applications‚ limitations and analysis

of Chemicals initiative was enforced‚ and about three years ahead of more stringent EPA emissions standards for diesel and heavy-duty engines. And that’s just the tip of the iceberg. In his Jan. 23 State of the Union address‚ President Bush called for tighter fuel economy standards‚ while the auto industry already is embroiled in a legal battle with California‚ Vermont and other states over scheduled emissions limits. So‚ yes‚ environmental regulations are a costly reality that manufacturers must

In 1950‚ A. Kastler from France proposed optical pumping (creation ofchanges in the distribution of filling of different atomic energy levels as aresult of excitation by light radiation) which earned him the Nobel Prizein physics in 1966

Consider fuel economy and CO2 emission rates. Widely acknowledged public utility vehicles such as the Toyota Coaster‚ Mitsubishi Coaster‚ and Hyundai County evidently have more efficient fuel consumption and CO2 output than our beloved jeepneys. Respectively‚ the average fuel consumption

From the data issued in the Air Pollution and Greenhouse Gas Emission Inventory Report by the Environmental Protection Department‚ every Hong Kong citizen produces 5.5 tons of CO2 in 2005. Though it is less than the 6.5 tons per capita of the Global Warming Potential Weighted Emission‚ we still can do something to contribute to our environment. We have to identify what the major sources of pollution are‚ so that we can further

1) Make a promise to protect clean air. Nearly 37 million children live in areas with unhealthy polluted air‚ and many pollution- associated illnesses have been on the rise. Yet polluters and their allies in Congress have been fighting efforts to reduce toxic industrial pollution and are trying to weaken existing clean air protections. That’s why NRDC has joined other public health‚ advocacy and environmental organizations in the "Clean Air Promise‚" a national campaign to protect the health of
