Comparison of copper contaminated soils, with similar uncontaminated controls.

Two sites of long-term copper polluted soil were sampled, along with nearby uncontaminated controls. All treatments were carried out and sampled in triplicate. A third site was samples at a copper mine, though the control site was of a dissimilar soil type and only single samples of each were taken.Marker taxa and gene functional groups will be identified between polluted and control soils.

选取两处长期受铜污染的土壤采样点位，并同步采集其邻近的未污染对照土壤样品。所有实验组均设置三次生物学重复并完成采样。第三处采样点位取自铜矿区，但该点位的对照土壤类型与污染点位的对照土壤类型存在差异，且仅对每组采集了单份样品。本研究将在污染土壤与对照土壤之间鉴定标记类群（marker taxa）与基因功能群（gene functional groups）。
