Mercury (Hg) levels in white stork (Ciconia ciconia) feathers collected in the mid-1990s from five northeastern Mediterranean (Greece) areas varied, with mean ranges between 301 ng g(-1) dry weight (dw) (Pinios River) and 1911 ng g(-1) dw (Sperchios Delta). A significant increase of Hg levels in chick feathers with age (surrogated by bill size) was found in the Evros and Pinios River areas, a nonsignificant increase in the Amvrakikos Gulf and the Epirus Region, and a marginally significant decrease in the Sperchios Delta area. For combined data of 1993 and 1995, Hg concentrations did not differ significantly in relation to hatching order among broods but differed significantly in relation to brood size being higher in 4-chick broods than those in 3-chick broods. All 10 areas formed 4 groups with levels mutually significantly different. Highest levels were detected in the Evros, Axios, and Sperchios riverine areas, whereas the lowest levels occurred at Drama plain, which lacks large water bodies in its vicinity. Levels were lower than those associated with intoxication to other ciconiiform species.
20 世纪 90 年代中期在五个地中海东北部（希腊）地区采集的白头鹤（Ciconia ciconia）羽毛中的汞（Hg）含量不同，皮尼奥斯河的均值范围在 301ng g(-1)干重（dw）到 1911ng g(-1) dw（斯佩尔基奥斯三角洲）之间。在埃夫罗斯河和皮尼奥斯河地区，雏鹤羽毛中的汞水平随着年龄（由喙大小推断）的增加而显著增加，在阿莫克拉基斯湾和伊庇鲁斯地区没有显著增加，在斯佩尔基奥斯三角洲地区则略有下降。对于 1993 年和 1995 年的综合数据，Hg 浓度与窝内孵化顺序之间没有显著差异，但与窝大小有关，4 只雏鸟的窝比 3 只雏鸟的窝 Hg 浓度更高。所有 10 个地区分为 4 组，组间水平相互显著不同。最高水平出现在埃夫罗斯河、阿克修斯河和斯佩尔基奥斯河等河流地区，而在附近没有大型水体的德拉马平原，Hg 浓度最低。这些水平低于与其他鹳形目物种中毒相关的水平。
