“…Mean surface loading is 7 ng/g, which is about equal to the endogenous concentration at the neutral site, but less than 10% of the concentrations at most acid sites. The concentrations in Table 2 fall within the range previously reported for various conifers: 12-137 ng/g for Norway spruce (Wyttenbach et al 1985), 100-170 ng/g for Picea rubens and Abies balsamea (Robarge et al 1989), and 9-36 ng/g for A. balsamea (Lin et al 1995). The highest Co value found in older needles of a single tree in the present work is 520 ng/g.…”

“…Its mean value is about 25 µg/g. Previously reported surface loadings are 21 µg/g (Wyttenbach et al 1985), 27 µg/g (Lin et al 1995) and 65 µg/g (Pfirrmann et al 1989). Comparison of these values with the endogenous concentrations shows that they are by no means negligible and that inclusion of the exogenous contamination in the analysis will lead to results unsuitable for plant physiological interpretation.…”

The concentrations of Fe, Zn and Co were determined in up to five successive needle age classes in 54 individual Norway spruce trees from eight different sites (soil pH 3.1-7.7). Fe concentrations (12-25 µg in needles from the current year) were lower than most published values, due to the removal of surface contamination prior to analysis. Fe showed a significant positive correlation with Al. Successive needle age classes either had constant values or showed an increase for Fe concentrations; individual trees on a given site were rather uniform in their behaviour. Zn concentrations were 19-40 µg/g. On acid sites, they showed a positive correlation with total soil concentrations. The majority of trees showed decreasing Zn concentrations in successive needle age classes, but constant or increasing concentrations were also found; site homogeneity was less than with Fe. Co concentrations differed between trees on a neutral soil (12 ng/g) and on acid soils (41-174 ng/g). They showed a significant positive correlation with Mn needle concentrations. The changes of Co with needle age in most, but not all, trees were similar to those of Zn. The different changes of Fe, Zn and Co with needle age may be due to a different retranslocation. A modest retranslocation of Fe as opposed to a high retranslocation of Zn and Co (in most trees) is consistent with the observed behaviour.

“…No literature regarding the use of P. glauca for biomonitoring is available while, A. balsamea is documented to be an effective species for determining atmospheric concentrations of trace metals through needle analysis [10]. Beckett et al (2000) [6] indicated an increase in the capture efficiency of atmospheric pollutants with intricate branch compositions and numerous smaller needles.…”

Conifer needles bioaccumulate atmospheric pollutants, including trace metals, and may be used to monitor variations in atmospheric concentration. Needles were analyzed to determine whether a correlation exists between elevations and trace metal concentrations in proximity to roadways and other non-point sources. Composite samples of white spruce (Picea glauca) and balsam fir (Abies balsamea) needles were collected along hillsides in eastern and western Calgary, respectively. A combined total of 11 sites was sampled along two transects of increasing elevation. Qualitative and quantitative analysis of trace metal concentrations was completed using inductively coupled plasma-mass spectrometry (ICP-MS) and synthesized using regression analysis. The concentrations of cobalt, nickel, and calcium in the samples were found to exhibit a significant (P < 0.05) relationship with respect to elevation and proximity to roadways.

Chemical analysis of plants is often done without paying attention to the ubiquitous natural presence of exogenous material on the plant surface. The analytical result will then be higher than the endogenous plant concentration. It is shown that this error can be related to three parameters: (i) the surface loading L, (ii) the enrichment factor (EF) of the exogenous material with respect to the soil, and (iii) the plant-to-soil concentration ratio (CR). These factors are considered for 19 essential and trace elements and the results indicate that the error can range from insignificant to disastrous. Experimental data are mostly for needles of spruce trees growing in a relatively clean surrounding, but the proposed relations can be extended to estimate the effect for other plant species and surroundings.
