Atmospheric Pollution in Beijing, China, as Recorded in Sediments of the Summer Palace Lake

Abstract

The fluxes of heavy-metals, and the fly-ash component magnetite from coal-burning, to sediments of the Lake of the Summer Palace in Beijing, China, have increased measurably over the last fifty years. The excess metal contents and the magnetite are attributed to the combustion of coal.Even with a doubling of coal usage by the year AD 2000. the anthropogenic metal fluxes in Beijing, China, will still be less than those recorded for recent times in metropolitan Tokyo and US lakes. In principle, these fluxes can be reduced by the installation of appropriate emission controls at the coal-burning facilities.
