Zinc oxide nanoparticles (n-ZnO) are widely used metal-based nanoparticles in electronics and personal care products that accumulate in aquatic environments from multiple non-point sources. In this study, we evaluated the effects of n-ZnO in a model organism, a mussel Unio tumidus, and the potential modulation of these effects by common co-occurring environmental stressors. Male U. tumidus ...

Impacts of copper on aquatic ecosystems

The Impacts of Copper on Aquatic Ecosystems The use of copper in anti-fouling paint for boat hulls demonstrates that it is highly toxic to aquatic organisms. In fact, copper is one of the most toxic metals to aquatic organisms and ecosystems. Because copper is an algaecide, it is not surprising that it causes decreased algal growth when inadvertently discharged to a water body. Algae are at ...

Environmental impact of mining - Wikipedia

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...

The Effects of Iron in Water on Aquatic Life | …

Iron in water has many effects on aquatic life, both good and bad. Iron (Fe) occurs naturally in water at a rate of roughly 1-3 parts per billion (ppb) in ocean water, about 1 part per million (ppm) in river water and 100ppm in groundwater. Iron comes from various minerals in the soil, which is why groundwater contains the highest iron concentrations. Iron levels in water vary depending on ...

Metals in the environment

The remaining fraction of total metal that actually interacts with aquatic organisms is called the bioavailable metal. In the environment, metals do not often occur singly, but as mixtures. Therefore, in order to be able to begin to fully understand the ecological effects of metals in the environment we must look at mixtures.
