Samples of the slime mold Fuligo septica (L.) Wiggers were collected from an ecologically diverse selection of sites across the former USSR and in North Korea to determine their Zn concentrations. Plasmodia were collected from trees, rocks, soils, the walls of buildings and a variety of other materials and structures from 1990 to 1996. The biomass collected ranged from 305 to 968 mg, whereas Zn concentrations in plasmodia of F. septica ranged from 8400 to 23,000 mg kg(-1) dry wt. (mean and standard error = 14,200 +/- 860 mg kg(-1) dry wt.). No clear trend as to which areas produced F. septica with the highest Zn concentrations was discernable. Nor was it possible to identify any particular substrate on which F. septica grew that produced noticeably high Zn concentrations. For example, forest litter on which F. septica was found had Zn concentrations of only 25 to 130 mg kg(-1) dry wt. Our data confirm the only other study showing hyperaccumulation of Zn in F. septica, which was carried out in Finland. This ability seems to be unique to this species, but how or why it does this, or why such high Zn concentrations are not toxic to F. septica, are questions requiring future research.
从苏联和朝鲜各地生态多样的地点采集了黏菌绒泡菌（Fuligo septica (L.) Wiggers）的样本，以测定其锌浓度。1990年至1996年期间，从树木、岩石、土壤、建筑物墙壁以及各种其他材料和结构上采集了原质团。采集的生物量在305至968毫克之间，而绒泡菌原质团中的锌浓度在8400至23000毫克/千克干重之间（平均值和标准误差 = 14200 ± 860毫克/千克干重）。无法 discernable出哪些地区产生的锌浓度最高的绒泡菌有明显趋势。也无法确定绒泡菌生长的任何特定底物会产生明显高的锌浓度。例如，发现有绒泡菌的森林凋落物的锌浓度仅为25至130毫克/千克干重。我们的数据证实了在芬兰进行的另一项唯一显示绒泡菌中超量积累锌的研究。这种能力似乎是该物种独有的，但它如何或为何这样做，或者为何如此高的锌浓度对绒泡菌无毒，这些都是需要未来研究的问题。 （注：原文中“discernable”拼写有误，正确拼写应为“discernible” ）
