: Between 1987-88 and 1989-90, 18 Sarus cranes (Grus antigone), more than 50 collared doves (Streptopelia decaocto) and a few blue rock pigeons (Columba livia) were found dead during winter in Keoladeo National Park, Bharatpur, which coincided with the application of aldrin in the crop fields around the Park. Brain tissue of Sarus cranes, collared doves and blue rock pigeons contained an average of 19.33 (3.56-43.46), 15.19 (7.40-20.70), and 20.42 (14.61-26.23) ppm, wet weight, of dieldrin, respectively. Dieldrin in other tissues ranged from 0.78 ppm to 92.26 ppm in Sarus cranes, 3.44 ppm to 66.17 ppm in collared doves and 16.92 ppm to 20.99 ppm in blue rock pigeons. Residues of aldrin were as high as 89.75 ppm in the gastrointestinal tract of a Sarus crane and 104.00 ppm in a collared dove. Very high residues of aldrin in the gastrointestinal tract, and dieldrin at much higher quantities in the brain than the lethal level (4-5 ppm) clearly indicate that dieldrin, after being metabolized from aldrin, was responsible for the deaths. A decline in the breeding population of Sarus cranes in Keoladeo National Park has been noticed, and is suspected to be an indication of its general population trend. The Registration Committee under the Indian Insecticide Act of 1968 has decided to include aldrin in the banned list with the ban taking effect from January 1994.
1987-88 年至 1989-90 年期间，在巴尔哈特区基奥拉德奥国家公园，有 18 只大鸨（Grus antigone）、50 多只珠颈斑鸠（Streptopelia decaocto）和几只蓝鸽（Columba livia）在冬季死亡，而此时正值公园周围农田使用艾氏剂。大鸨、珠颈斑鸠和蓝鸽的脑组织中滴滴涕的含量分别为 19.33（3.56-43.46）、15.19（7.40-20.70）和 20.42（14.61-26.23）ppm（湿重）。大鸨其他组织中的滴滴涕含量为 0.78-92.26ppm，珠颈斑鸠为 3.44-66.17ppm，蓝鸽为 16.92-20.99ppm。大鸨的胃肠道中艾氏剂的残留量高达 89.75ppm，珠颈斑鸠为 104.00ppm。大鸨胃肠道中的艾氏剂残留量极高，大脑中的滴滴涕含量远高于致死水平（4-5ppm），这表明滴滴涕是由艾氏剂代谢而来，是导致死亡的原因。基奥拉德奥国家公园大鸨的繁殖数量有所下降，这可能表明其总体数量呈下降趋势。1968 年《印度杀虫剂法》下的注册委员会决定将艾氏剂列入禁用名单，该禁令将于 1994 年 1 月生效。
