For a period of 60 days, the terrestrial moss Plagiothecium denticulatum was transplanted from a clean control site to a soil contaminated with crude oil exudates (Krosno, South East Poland). Native P. denticulatum growing on this contaminated soil was collected during the same period. Concentrations of the metals Al, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, V, and Zn as well as the macroelements N, P, K, Ca, Mg, and S were determined in P. denticulatum and in soils from the contaminated and control sites. Contaminated soil was the main contributor of Ba, Co, Cr, Cu, Fe, Mn, Ni, Pb, V, and Zn to native and transplanted P. denticulatum. Other sources of contamination apart from the soil existed for Cd and Cu. Transplanted P. denticulatum accumulated significantly more Al, Cr, Cu, Ni, Pb, and Zn, and native P. denticulatum accumulated significantly more N, P, K, and Ca. Higher levels of N, P, K, and Ca in native P. denticulatum indicates a possible mechanism to prevent the loss of these elements as observed in the transplanted P. denticulatum.
在60天的时间里，将陆生苔藓细齿匍灯藓从一个清洁的对照地点移植到受原油渗出物污染的土壤中（波兰东南部的克罗斯诺）。同期采集了生长在这种污染土壤上的本地细齿匍灯藓。测定了细齿匍灯藓以及污染场地和对照场地土壤中金属铝（Al）、钡（Ba）、镉（Cd）、钴（Co）、铬（Cr）、铜（Cu）、铁（Fe）、锰（Mn）、镍（Ni）、铅（Pb）、钒（V）和锌（Zn）以及大量元素氮（N）、磷（P）、钾（K）、钙（Ca）、镁（Mg）和硫（S）的含量。污染土壤是本地和移植的细齿匍灯藓中钡、钴、铬、铜、铁、锰、镍、铅、钒和锌的主要污染源。镉和铜除了土壤之外还有其他污染来源。移植的细齿匍灯藓积累了显著更多的铝、铬、铜、镍、铅和锌，而本地细齿匍灯藓积累了显著更多的氮、磷、钾和钙。本地细齿匍灯藓中较高水平的氮、磷、钾和钙表明了一种可能的机制，以防止这些元素像在移植的细齿匍灯藓中所观察到的那样流失。
