Abstract. Cadmium concentrations of a common macrophyte, the yellow pond lily (Nuphar variegatum) were investigated from peatlands with a range in pH (4.4–6.3), alkalinity (0–181 μeq/L Ca), DOC (5.1–16.8 mg/L), and sediment organic content (20–88%). Cd concentrations in Nuphar ranged from 0.3 to 1.51 μg/g in the leaves and from 0.46 to 1.51 μg/g in the petioles, and was significantly higher in the petioles than in the leaves (p = 0.014; t-Test). Significant and negative correlations between… Expand
Total Hg in Water, Sediment, and Four Species of Aquatic Macrophytes in the St. Lawrence River, near Cornwall, Ontario
Previous research on mercury (Hg) in lakes and rivers has identified pH, alkalinity, and organic carbon levels as the major environmental variables which predict Hg concentrations in fish andExpand
Biomonitoring of tin and arsenic in different compartments of a limnic ecosystem with emphasis on Corbicula fluminea and Dikerogammarus villosus.
The results indicate that Corbicula fluminea and Dikerogammarus villosus are suitable passive biomonitoring organisms for Sn, but As levels might be actively regulated. Expand
Metal Contamination Characteristics of Lepidium sativum in a Phosphate-, Saline-, and Nitrate-Contaminated Media
In this research we investigated the ability of cress seeds (Lepidium sativum L.) to grow in an aqueous media with metal toxicities. The toxicity of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn ions wereExpand
Effects of heavy metals on growth and bioaccumulation of the annual halophytes Atriplex hortensis and A. rosea.
3 Abstract: Heavy metals such Zn, Pb, Cu and Cd can cause a non-degradable pollution in numerous sites in France as well as in Tunisia, or elsewhere. This pollution resulting from various humanExpand
The results showed that dose response of heavy metals were inversely proportional to germination, root growth and dry biomass, signifying that trees can be successfully used for phytoremediation. Expand
Relative toxicity of various nickel species on seed germination and early seedling growth of Vigna unguiculata L.
Cowpea (Vigna unguiculata L.) seedlings were raised in water culture and exposed to varying concentrations (1,10,100,1000μM) of nickel as Ni (NO 3 ) 2 NiSO 4 and NiCl 2 with a view to compare theExpand

Heavy metals such Zn, Pb, Cu and Cd can cause a non-degradable pollution in numerous sites in France as well as in Tunisia, or elsewhere. This pollution resulting from various human pollutingExpand
Heavy Metal Biosorption by Plant Biomass of the Macrophyte Ludwigia Stolonifera
Ludwigia stolonifera biomass of roots, floating roots and leaves were tested for their performance as heavy metal biofilters. Cadmium (Cd) and nickel (Ni) (50 ppm) solutions were filtered throughExpand
A pot experiment was carried out to study the responses of Pisum sativum L. growing in Copper, Zinc and Lead treated soil. Three different soil concentrations of each heavy metal were prepared fromExpand
Non-destructive estimation of the leaf area in Nuphar lutea L. (Nymphaeaceae)
The formulas for calculating the surface area of a leaf (main photosynthetic organ of N. lutea) were obtained and the data obtained provide a better picture of this species productivity and will allow further to estimate the contribution of thisspecies to the overall productivity of water bodies and watercourses.

Accumulation of copper and zinc in the yellow water lily, Nuphar variegatum: relationships to metal partitioning in the adjacent lake sediments
Relationships between the partitioning of Cu and Zn in lake sediments and their availability to the yellow water lily, Nuphar variegatum, were examined downstream from a major Cu/Zn mining andExpand
Factors affecting trace-metal bioaccumulation in Finnish headwater lakes.
Aquatic plants were, in general, the best indicator group concerning differences in trace-metal bioaccumulation in lakes with different acidity, and there was some evidence that a higher concentration of TOC in water may reduce bio Accumulation of Pb, Cd and Zn in aquatic plants and fish. Expand
Biogeochemical Investigation of Big Creek Marsh, Lake Erie, Ontario
Abstract Geochemical composition of sediment, uptake of nutrients and metals by macrophytes, and nutrient and metal concentration in the water was investigated at six selected stations in Big CreekExpand
Relationship between concentrations of aluminum, cadmium, lead, and zinc in water, sediments, and aquatic macrophytes in six acidic lakes
Assessment of trace element behavior in a series of six clear-water acidic lakes in northwestern New Jersey indicated that, while there was considerable variation over time, in general, the mostExpand
Effects of Aluminum on the Leopard Frog, Rana pipiens: Life Stag Comparisons and Aluminum Uptake
In embryos and prestage 25 tadpoles, Al ameliorated the toxic effects of very low pH's, while becoming toxic at higher pH's (4.6–4.8) and Al (0–1000 μg∙:L−1}, and to pH 6.5 with no Al present. Expand
Empirical relationships between the element composition of aquatic macrophytes and their underlying sediments
A simple view of the role of rooted macrophytes in element cycling sees them as pumps retrieving buried elements from the sediment profile. To investigate the relationship between the elementalExpand
Acidification and Toxicity of Metals to Aquatic Biota

The effects of acidification on the geochemistry of Al, Cd, Pb and Hg in freshwater environments: a literature review.
This critical review of the literature over the last decade concerned with the interaction of acidification with these four metals has attempted both to provide an assessment of the current state of knowledge and to emphasize those areas where significant progress has been made since the possible implications of environmental acidification on metal geochemistry became widely appreciated in the late 1970s.
