Gridded usage inventories of technical hexachlorocyclohexane and lindane for china with 1/6 degrees latitude by 1/4 degrees longitude resolution

China banned the use of technical HCH (BHC: 1,2,3,4,5,6-hexachlorocyclohexa ne) in 1983; lindane has been used in this country since 1991. The total pr oduction was around 4 million t for technical HCH from 1952 to 1984, and 11 ,400 t for lindane between 1991 and 2000. Though the total produced technic al HCH was considered to be used in China, only 3,200 t of lindane were use d between 1991 and 2000 with the rest for export or on unused stack. Annual usage of these two compounds was located into each province first and then broken for different crops. Inventories of gridded usage of both technical HCH and lindane with 1/6 degrees by 1/4 degrees latitude/longitude resolut ion have been created by different gridded cropland data sets as surrogate data. The intensive use of technical HCH on croplands was concentrated in t he southeastern part of China, but the use of lindane was concentrated in t he northern part of China.
