Gridded Canadian lindane usage inventories with 1/6° x 1/4° latitude and longitude resolution

摘要

Lindane is one of the organochlorine pesticides, a major portion of persistent organic pollutants. Major use of lindane in Canada was on canola and corn. In this paper, temporal and spatial use trends of this pesticide in Canada between 1970 and 2000 have been presented Use of lindane on canola and com in Canada between 1970 and 2000 has been estimated to be 9kt, with highest value (558 t) in 1994. The intensive use of this pesticide has been in the Prairie Region of Canada, the provinces of Alberta, Saskatchewan and Manitoba, as high as 8.5 kt, 94% of total usage. Inventories of gridded usage of lindane in Canada with 1/6° by 1/4° latitude/longitude resolution have been created by gridded canola and corn data sets with the same resolution as surrogate data. The highest application of lindane is around 151 per grid cell, located in the Prairie Region.
