1972 年春天，伊利诺伊州赖斯湖爆发铅中毒，约 1500 只水禽死亡。在 394 只被发现死亡或濒临死亡的鸟类中，小斑鸠 (Aythya affinis) 占 75%。在检查的 96 只鱼中，75% 的鱼砂囊中至少有 1 颗铅丸，36% 的鱼有超过 10 颗。平均而言，鱼在死亡前体重减轻了 30-35%。肝脏中铅的平均浓度为 46 +/- 4 ppm，肾脏中为 66 +/- 8 ppm，翼骨（桡骨和尺骨）中的铅浓度为 40 +/- 5 ppm。未成熟鱼翅骨中的浓度大约是成鱼的两倍。 (1)砂囊中的颗粒数与体重、(2)砂囊中的颗粒数与肾脏中的铅ppm、(3)砂囊中的颗粒数与翼骨中的铅ppm、以及(4)肝脏中的铅ppm与翼骨中的铅ppm之间存在正相关。
About 1500 waterfowl died during an outbreak of lead poisoning at Rice Lake, Illinois, during the spring of 1972. The lesser scaup (Aythya affinis) made up 75 percent of 394 birds found dead or dying. Of 96 scaups examined, 75 percent had at least 1 lead pellet in the gizzard and 36 percent had more than 10. The scaups had lost, on the average, 30-35 percent of their body weights before dying. Concentrations of lead in scaups averaged 46 +/- 4 ppm in liver, 66 +/- 8 ppm in kidney, and 40 +/- 5 ppm in wing bones (radius and ulna). Concentrations in wing bones were approximately twice as great in immature scaups as in adults. Positive correlations existed between (1) the number of pellets in the gizzard and body weight, (2) the number of pellets in the gizzard and ppm of lead in kidney, (3) the number of pellets in the gizzard and ppm of lead in wing bones, and (4) ppm of lead in liver and ppm of lead in wing bones.
