“…Preliminary studies with ValSubmerged plants have often been proposed as bioindicators of the presence of trace metal contamination in the aquatic environment (Aulio 1986;Brix et al 1983;Greger and Kautsky 1993;Mortimer 1985;Ray and White 1976). To be a good candidate as a biological indicator, a plant species should (i) be representative of the area; (ii) be widely distributed, abundant, and easy to collect; (iii) have a high tolerance for heavy metals and a high concentration factor; and (iv) be reasonably easy to identify unequivocally (Ray and White 1979).…”

ST-CYR, L., and CAMPBELL, P.G.C. 1994. Trace metals in submerged plants of the St. Lawrence River. Can. J. Bot. 72: 429-439. Vallisneria arnericana Michx. (wild celery), a submerged plant ubiquitous in the fluvial lakes St. Louis and St. Pierre of the St.Lawrence River, Quebec, shows potential as a bioindicator species for trace metals in its environment. The Cd, Cr, Cu, Ni, Pb, and Zn concentrations in V. arnericana leaves reflect spatial variations in environmental contamination and represent bioavailable trace metals potentially transferable through the food chain to higher orgaeisms. With the exception of Pb, V. arnericana concentrates trace metals to higher levels in its aboveground tissues than does Potarnogeton richardsonii (A. Bennett) Rydb., another abundant species in the studied lakes, although the two species show the same trend to higher trace metal concentrations at the more contaminated stations. Vallisneria arnericana from Lake St. Pierre shows higher concentrations for all trace metals studied than does the same species from Lake St. Louis (mean concentrations in pg/g dry wt. for Lake St. Pierre versus Lake St. Louis: Cd, 1.62 vs. 0.89; Cr, 3.9 vs. 2.5; Cu, 20.0 vs. 16.5; Ni, 13.1 vs. 5.6; Pb, 3.3 vs. 2.0; Zn, 130 vs. 91). Mean concentrations of Cd, Cr, Ni, and Zn exceed median values of these concentrations for aquatic plants from contaminated sites, as reported in the literature.

“…Wherever possible, the reference sites were selected to represent an upstream uninfluenced site, to contrast with a directly influenced site downstream from a point source. Thus, upstream/downstream comparisons may be made in order to attribute any observed differences in demographic variables (shoot survival, rates of clonal growth, reproductive activity) between the plants grown at these two locations to the contaminants detected in a specific industrial or municipal effluent (Ray & White, 1976;Mortimer, 1985;Currie & Phinney, 1985). Five male and five female ramets (cloned plants), each a representative of a different genotype, were planted in tubs containing sediment obtained from an island (Turkey Is.)…”

In a number of disciplines including ecology, ecotoxicology, water quality management, water resource management, fishery biology etc., there is significant interest in the testing of new materials, environmental samples (of water or sediments) and specific sites, in terms of their effects on biota. In the first instance, we consider various sources of aquatic pollution, sources typically associated with developed areas of the world. Historically, much water quality assessment has been performed by researchers with a background in chemistry or engineering, thus chemical analysis was a dominant form of assessment. However, chemical analyses, particularly of such materials as organochlorines and polyaromatic hydrocarbons can be expensive, and local environmental factors may cause the actual exposure of an organism to be little correlated with chemical concentrations in the surrounding water or sediments. To a large extent toxicity testing has proceeded independently of environmental quality assessment in situ, and the work has been done by different, and differently-trained researchers. Here we attempt to bring together the various forms of biological assessment of aquatic pollution, because in our opinion it is worth developing a coherent framework for the application of this powerful tool. Biotic assessment in its most primitive form involves the simple tracking of mortality in exposed organisms. However, in most natural environments it is extended, chronic exposure to contaminants that has the most wide-ranging and irreversible repercussions--thus measures of sub-lethal impairment are favoured. From an ecological standpoint, it is most valuable to assess ecological effects by direct study of in situ contaminant body burdens and impairment of growth and reproduction compared with 'clean' sites. A distinction is made here between bioindication and biomonitoring, and a case is made for including aquatic macrophytes (angiosperms) in studies of contaminant levels and effects in the biota. It is apparent that there is a concurrent need for laboratory-based testing of new industrial by-products before any are released in the environment, and such studies should aid the investigation of mechanisms and modes of toxicity, but environmental assessment, and tracking of improvements in environmental quality are most effectively achieved by active biomonitoring experiments.

Accumulated chromate from the medium was responsible for the inhibition of the photosystem II. In this study, we focused on the alteration of the photosynthetic apparatus through analysis of the Chlorophyll a fluorescence of duckweed half-fronds. Chromate induced the K step on the fluorescence transient in 6-BA treated half-fronds. Chromate affected several targets of photosynthetic II apparatus. The oxygen evolving complex (OEC) was the more highly sensitive to chromate than the reaction center (RC) in 6-BA treated half-fronds. We showed that 6-BA treated half-fronds would be taken as a potential useful system to estimate the effect of water pollution.
