“…The BCF is mostly used for the purpose of evaluating the bioaccumulation power in macroalgae. The BCF allows for the estimation of the status of an aquatic ecosystem's maintenance stability or for monitoring the contamination thereof (Conti and Cecchetti 2001). In our study, the BCF was used to determine as the difference between the bioaccumulation of metals in two freshwater Ulva populations.…”

The accumulation of metal (Co, Cr, Cu, Mn and Zn) in freshwater Ulva (Chlorophyta) and its habitat

The possibility of using freshwater Ulva (Chlorophyta) as a bioaccumulator of metals (Co, Cr, Cu, Mn and Zn) in lake and river water was examined weekly in the summer of 2010 in three types of samples: the water, the sediment and the thalli of Ulva. Samples of freshwater Ulva were collected from two aqueous ecosystems lie 250 km away from the basin of the Baltic Sea and 53 km from each other. A flow lake located in the centre of the big city was the first water reservoir (ten sites) and second, the suburban river (six sites). The mean metal concentrations in the Ulva tissue from the river and the lake decreased in the following order:respectively. Moreover, a negative and statistically significant correlation between Mn concentrations in the Ulva thalli and the river water was observed. Additionally, numerous correlations were noted between the different concentrations of metals within the Ulva thalli, in the water and in the sediment. The great concentrations of Mn and Zn and the smallest of Co were found in thalli of Ulva, irrespective of the type of the ecosystem from which samples of algal thalli originated. Freshwater Ulva populations examined in this study were clearly characterized a dozen or so times by the higher Mn and Cr accumulation than taxa from that genera coming from sea ecosystems. The calculated bioconcentration factor confirm the high potential for freshwater Ulva to be a bioaccumulator of trace metals in freshwater ecosystems.

“…The most commonly used are lichens [7,24] and mosses [43,45]. The latter is well known for the monitoring of heavy metal atmospheric deposition in terrestrial ecosystem [48] and Sphagnum mosses have also been used to reconstruct metal atmospheric deposition in peatlands [20,59].…”

Relationship Between Testate Amoeba (Protist) Communities and Atmospheric Heavy Metals Accumulated in Barbula indica (Bryophyta) in Vietnam

et al. 2006

We studied the relationships between testate amoeba communities and heavy metal (Pb, Cd, Zn, Ni, Cu, Mn, and Fe) concentrations in the moss Barbula indica sampled at 29 sites in and around the city of Hanoi (Vietnam). Our first approach was to compare the heavy metal concentrations and testate amoeba variables between the city (zone 1) and the surrounding (zone 2). Mean moss concentrations of Pb, Cd, Zn, Ni, and Cu were significantly higher and testate amoeba species richness and abundance were significantly lower in zone 1 and the abundance of eight taxa differed significantly between the two zones. We then studied the correlation between heavy metals and testate amoebae. Species richness and abundance were correlated negatively to Pb concentration. Shannon H 0 was negatively correlated to both Pb and Cd. The abundance of several species was negatively correlated with Pb, Cd, Zn, and Ni; however, at the community level, Pb emerged as the only significant variable in a redundancy analysis. Our results suggest that testate amoebae are sensitive to and may be good bioindicators for heavy metal pollution, especially lead. Further research is needed to understand the causal relationships underlying the observed patterns.

“…While air quality is now regularly monitored in some exposed areas, the impact of these various atmospheric pollutants on living organisms remains a poorly known phenomenon. The use of plant bioindicators has proved to be a complementary method of investigation for pollutant analysis, insofar as they constitute real biological integrators, capable of providing a basis for assessment of environmental quality and/or contamination (Hawksworth and Rose, 1970;Howell, 1970;Seaward, 1993;Monna et al, 1999;Alaimo et al, 2000;Conti and Cecchetti, 2001;Omasa et al, 2002). Over the past few years, research has focused on the measurement of chemical compounds in plants, as indicators of a particular environment state.…”

Phenolic compounds content in Pinus halepensis Mill. needles: a bioindicator of air pollution

et al. 2003

View full text Add to dashboard Cite

Foliar phenol concentrations (total and simple phenols) were determined in Aleppo pine (Pinus halepensis Mill.) needles collected in June 2000, from 6 sites affected by various forms of atmospheric pollutants (NO, NO 2 , NO x , O 3 and SO 2 ) monitored during two months. Results show an increase in total phenol content with exposure to sulphur dioxide and a reduction with exposure to nitrogen oxide pollution. p-Coumaric acid, syringic acid and 4-hydroxybenzoic acid concentrations increase with exposure to nitrogen oxide pollution, whereas gallic acid and vanillin decrease in the presence respectively of sulphur dioxide and ozone. This in situ work confirms the major interest of using total and simple phenolic compounds of P. halepensis as biological indicators of air quality.
