%X In China,arsenic contents of representative coal samples,which are selected base on the reserves of coal-cumulating areas and the production of every city in 2001,were studied.Three contents of arsenic in Chinese coals can be obtained by different evaluating methods.First,the average mean of arsenic content in these coal samples can be regard as the average content of arsenic in Chinese coals and it is 6.43mg/kg;Second,weighted by the reserves of five coal-cumulating areas and the average content of arsenic in Chinese coals is 5.28mg/kg;Third,weighted by the production of 26 cities in 2001 and the average content of arsenic in Chinese coals is 6.03 mg/kg.The influence of high arsenic coal can be ignored because the reserve of it is very small.For different purposes,different average content of arsenic in Chinese coals should be selected in order to get more reasonable value.
