Upside: The western world is increasingly switching to
fluorescent, energy-saving lightbulbs.
Downside: They contain mercury, while traditional incandescent bulbs do not.
The bulbs emit the mercury when they're disposed of in dumps. Their makers say this is OK because the amount of mercury emissions from power stations that occur as a result of powering the old-style bulbs is greater than the mercury contained in the energy-saving bulbs.
But, researchers are now saying that the mercury emitted from fluorescent bulbs in landfills is in a vaporous state. This means it gets into the food chain more easily than the mercury emitted by coal-powered power stations.
