“…The use of total peroxidases as bioindicators of the effects of SO 2 on conifers has been studied in both short-term (KHAN and MALHOTRA 1982) and long-term fumigation experiments (KATAINEN et al 1984;BENDER et al 1990;KLUMPP et al 1989) and in the field (NIEMTUR 1979;HUTTUNEN 1981, JOKINEN et al 1983, NYMAN 1986. Changes in peroxidase activities are thought to be reasonably sensitive means of detecting local pollution stress in Scots pine needles under field conditions as well as experimentally, and peroxidase activity has proved to be reversible in response to diminished pollution stress (NYMAN 1986).…”

A gradient survey was carried out in order to compare peroxidase activity in Scots pine (Pinus sylvestris) needles in relation to distance from the industrial centre of Monchegorsk, on the Kola Peninsula in north-western Russia. Apoplastic and total peroxidase activity and sulphur (S), nickel (Ni) and copper (Cu) content in the needles of mature trees were measured on seven plots located between 10 and 110 km from the pollution source. Peroxidase activities in both current-and previous-year needles increased towards the smelters and showed a positive correlation with needle S, Cu and Ni concentrations. Total peroxidase activities showed a more obvious relationship to the pollution gradient in winter than in autumn. The element contents in the current year needles averaged 1649 ppm (S), 128 ppm (Ni) and 118 ppm (Cu) close to the smelters, 1212 ppm (S), 37 ppm (Ni) and 67 ppm (Cu) at a distance of 40 km and 831 ppm (S), 7 ppm (Ni) and 1 ppm (Cu) at the most distant sampling plot.This study showed that both the apoplastic and total peroxidase activities responded to heavy metal and sulphur pollution up to 40 km from the smelters in winter, which indicated an increased oxidative stress in this area. The harsh climate conditions and the high pollution levels may have had additive effects. However, as peroxidases are considered a general indicator of stress, it is not possible to evaluate the extent to which single pollutants contribute to this enzyme activity.

“…Exposure of pine trees to a mixture of SO, and NO.^ {c. \ 5 ppb of each gas) in an open field fumigation experiment caused a small decrease in superoxide dismura.se activity in pine needles (Wingsle & Hallgren, 1993). In different clones of Scots pine exposed to industrial air pollution increases as well as decreases in peroxidase activity were observed (Nyman, 1986).…”

SUMMARY'Needles from young and mature Scots pine trees {Pinus sylveslris) were collected at three field sites in eastern Germany, i.e. Menz, Taura, and Gossa, which differed in SO^ pollution. Current and previous year's needles from the polluted sites Taura and Gossa (yearly mean of SO^: 26 ppb) contained approximately 100-120 /^mo! sulphate g~' d. wt, whereas needles from the unpolluted site, Menz (yearly mean of SO^: 3 ppb) contained 30-65//mol sulphate g"' d. wt. The apoplastic sulphate content was in the order of 0 3 I °,, of total sulphate and corresponded to concentrations of 0-6-1-2 mM in needles from Menz and to 1*5-2 mM in needles from Gossa. In needles from the polluted sites the contents of giutathione, cysteine, y-glutamylcysteine, and soluble protein were higher than in needles from Menz. Despite the clear increases in sulphur-containing compounds, pigment content and activities of superoxide dismutase, total peroxidase and apoplastic peroxidase (on the basis of d. wt) were not significantly different. When enzymatic activities were related to protein, lowest activities were found in needles from the site with the highest SO.^-pollution. The results show that it is not possible to use the activities of peroxidases or superoxide dismutases as biomarkers for S().^-mediated stress in pine needles. It remains open whether the needles from the polluted sites suffered from greater oxidative stress than the needles from the less polluted site.

“…The mechanism of the influence of different pollutants on plant organism is associated with oxidative damage at the cellular level (Tanaka and Sugahara 1980, Huttunen and Heiska 1988, Wingsle and H~illgren 1993. The sensitivity to different pollutants differs between plants and even between clones of the same species (Nyman 1986, Darall 1989. The advantage of the presented study was the known origin of plant material simultaneously planted on polluted and nonpolluted areas.…”

“…On the other hand in Scots pine and Norway spruce trees treated artificially with different pollutants such as SO 2 , NO 2, 03 , the activity of enzyme scavenging system such as SOD and GR was reduced (Wingsle et al 1992, Wingsle andH~llgren 1993, Kronfus et aL I998). Also in different clones of Scots pine exposed to industrial air pollution changes in PO activity were noted (Nyman 1986). Plant material for our investigations was collected from three experimental trials of Scots pine trees including 20 European provenances, established 16 years ago in Luboti, close to a phosphate fertiliser factory, in Gtog6w, close to a copper foundry and in K6rnik (20 and 100 km respectively from polluted stands), as the control stand.…”

The involvement of enzymic antioxidant system, superoxide dismutase, guaiacol peroxidase, ascorbate peroxidase in detense reaction to environmental stress evoked by air and soil pollution, was seasonally studied on three populations of Scots pine (Pinus syh,estris L.) growing on experimental areas close two industrial objects in Poland. The first of them (Lubofi) is localised near a phosphate fertiliser factory, the second (Gtog6w) near a copper foundry, and control stand is placed in K6rnik. Gtogdw is the most polluted site, where in 1998 monthly mean daily concentrations was: SO2 -17 ~g-m -3, NOx -12 ~g.m -~ and dust containing heavy metals (Cu, Pb, Cd) -29 ~g.m--'. Trees in Lubofi were influenced for many years by high concentration of SO2 and fluor compounds. Few years ago emissions were markedly reduced, but changes in the soil (low pH and high concentration of aluminium ions) still influence the growth of trees. In needles of two populations: 3 (Russia) and 8 (Poland), from the polluted sites Gtogdw and Lubofi, activities of superoxide dismutase (SOD) and guaiacol peroxidase (PO) were significantly higher compared to Kdrnik. However, in one population (16 -Slovakia), such dependance was not evident. Activity of ascorbate peroxidase (AP) measured in winter was also higher in needles from polluted sites. The resuits indicated that the sensitivity of free radical scavenging system in Scots pine needles differs among populations.
