“…The ecosystem response to copper addition has been studied in several natural aquatic environments. Effler et al (1980) noted a dramatic reduction in bacterial populations when copper sulfate was applied at 0.14-0.22 ~'mol/L to a lake, but the populations recovered fully in several days. In their study, copper was also shown to induce short-term stress and alteration in the natural succession of algae.…”

The Standardized Aquatic Microcosm (SAM) was used to assess the effects and behavior of copper at the ecosystem level. The concentration of algal cells and Daphnia magna, pH, dissolved organic carbon (DOC), and dissolved and ionic copper concentration were measured for 489 d and used to explain the recovery sequence of a community of organisms. The results indicate that a resistant algal species was crucial for initiating the recovery sequence in these microcosms and that the timing of D. magna blooms was variable but highly correlated with decreasing ionic copper. In order to explain copper toxicity and the success of the recovery phase, a stepwise analysis of the functional role of the resistant algal species Oocystis pusilla, and the tolerance of D. magna was undertaken. These process studies determined that O. pusilla was a suitable food for D. magna, and that this algal species could also act as a major ligand for copper, although sorption was probably important only for a limited time during the bloom. These studies also concluded that copper bioavailability controlled toxicity because it was shown that D. magna from the microcosms exhibited no resistance to copper toxicity, even though the dissolved copper concentration was 5 times the LC50 value (concentration lethal to 50% of the population). DOC and pH, which were controlled by algal metabolism, were probably important for decreasing ionic copper, which allowed the recovery sequence to begin. Additional studies showed that the microcosm-derived DOC was able to complex copper at low pH and that DOC was highly correlated with reduced concentrations of ionic copper.

“…[3] Copper sulfate (CuSO 4 ) is one of the most widely used algaecides for phytoplankton control in fish ponds, reservoirs and lakes, as well as an herbicide. [4,5] At present, the extensive use of copper has raised concern about the consequences of copper treatment or natural or farmed organisms. [6−8] The toxicity of copper on adult fish, its accumulation within tissues, and its impacts on physiological mechanisms have been well studied, [9−14] including gilthead seabream.…”

In this study, the effects of exposure to copper (mortality and morphological alterations) on the early life stages of the gilthead seabream, Sparus aurata, were examined. Eggs/embryos and larvae were exposed to nominal concentrations of copper ranging from 0.0001 to 10 mg/L Cu (II) in the tests with eggs/embryos and 0.025 to 0.5 mg/L Cu (II) in the test with larvae. Duration of the assays was 48 hours for embryos and 96 hours for larvae. A high percentage of mortality was observed in embryos exposed to 0.1 mg/L (97.2%) and in larvae exposed to 0.5 mg/L (100%). The embryos proved the most sensitive to copper for the same duration of exposure. The acute toxicity expressed as LC(50) 48 hours was 0.054 (0.048-0.058) mg/L for embryos and 0.261 (0.182- 0.375) mg/L for larvae. Morphological alterations or abnormalities in embryos included irregular shapes of chorion, opacity and vitellus retraction/degeneration. In larvae we observed poor capacity to swim, trembling, myoskeletal defects, opacity and exophthalmia. Histopathological alterations are observed in S. aurata larvae. Mucous cells of the digestive tissue present a severe alteration with an increment of exudates. A great cellular disorganization in the renal tissue is observed. Results from this work indicate the high sensitivity of early life stages of Sparus aurata to copper (II) and the persistence of sublethal effects.

The fate and effects of copper in the environment are governed by a complex set of environmental processes that include binding to inorganic and organic ligands in water, soil, and sediments. In natural waters, these interactions can limit copper bioavailability and result in copper transport from the water column to the sediment. In the present study, data on the fate of copper added to lakes, microcosms, and mesocosms were compiled and analyzed to determine copper removal rates from the water column. Studies on copper behavior in sediment were also reviewed to assess the potential for remobilization. A previously developed, screening‐level fate and transport model (tableau input coupled kinetic equilibrium transport–unit world model [TICKET–UWM]) was parameterized and applied to quantify copper removal rates and remobilization in a standardized lake setting. Field and modeling results were reconciled within a framework that links copper removal rates to lake depths and solids fluxes. The results of these analyses provide converging evidence that, on a large scale, copper is removed relatively quickly from natural waters. For the majority of studies examined, more than 70% of the added copper was removed from the water column within 16 d of dosing.
