Heavy Metal Pollution Characteristics of Surface Sediments in Different Aquatic Ecosystems in Eastern China: A Comprehensive Understanding
Aquatic ecosystems in eastern China are suffering threats from heavy metal pollution because of rapid economic development and urbanization. Heavy metals in surface sediments were determined in five different aquatic ecosystems (river, reservoir, estuary, lake, and wetland ecosystems). The average Cd, Cr, Cu, Ni, Pb, and Zn concentrations were 0.716, 118, 37.3, 32.7, 56.6, and 204 mg/kg, respec...
متن کاملToxicity of Silver Nanoparticles in Aquatic Ecosystems: Salinity as the Main Cause in Reducing Toxicity
Background: In recent years, silver nanoparticles due to their antimicrobial properties, have formed about 56% of nanoparticles global production. Since the released nanoparticles ultimately enter water ecosystems, their maximum toxic effects are magnified in aquatic ecosystems. The aim of this study is to show how salinity can decrease the toxic effects of silver nanoparticles on exposed rai...
متن کاملThe CO2 balance of unproductive aquatic ecosystems
Community respiration (R) rates are scaled as the two-thirds power of the gross primary production (P) rates of aquatic ecosystems, indicating that the role of aquatic biota as carbon dioxide sources or sinks depends on its productivity. Unproductive aquatic ecosystems support a disproportionately higher respiration rate than that of productive aquatic ecosystems, tend to be heterotrophic (R > ...
متن کاملLakes, wetlands, and streams as predictors of land use/cover distribution.
The importance of the surrounding landscape to aquatic ecosystems has been well established. Most research linking aquatic ecosystems to landscapes has focused on the one-way effect of land on water. However, to understand fully the complex interactions between aquatic and terrestrial ecosystems, aquatic ecosystems must be seen not only as receptors of human modification of the landscape, but a...
متن کاملA review of the biological characteristics of suckermouth catfish (Hypostomus plecostomus Linnaeus, 1758) and its impacts on aquatic ecosystems
Following the report of suckermouth catfish (Hypostomus plecostomus) from Anzali Wetland, the present study was conducted to review the biological and ecological characteristics of this species and its effects on aquatic ecosystems. A literature review revealed that the suckermouth catfish is native to South America and one of the most popular species in the ornamental fish industry. This speci...
