The potential for delayed mortality following short-term episodic pollution events was evaluated by exposing cladocerans (Ceriodaphnia dubia) and rainbow trout (Oncorhynchus mykiss) to zinc (Zn) in various 1- to 48-h and 1- to 96-h exposures, respectively, followed by transferring the exposed organisms to clean water for up to 47 h for C. dubia and up to 95 h for trout for additional observation.

Water Quality Criteria for Copper Based on the BLM

Feb 06, 2017The bioavailability and toxicity of metals to aquatic organisms are highly dependent on water quality parameters in freshwaters. The biotic ligand model (BLM) for copper is an approach to generate the water quality criteria (WQC) with water chemistry in the ambient environment. However, few studies were carried out on the WQCs for copper based on the BLM approach in China.

Foods High in Copper + How to Get More Copper in Your Diet

May 09, 2018Although copper toxicity is possible, it's rare in the general population. Contaminated water supplies or the contamination of beverages that are stored in copper-containing containers can lead to copper poisoning. That's why toxic copper mugs shouldn't be used for your Moscow mules, as they allow copper to leach into your drink.

As a class of inorganic compounds, heavy metals are known to be naturally distributed worldwide, which can be discharged from human activities including farming, effluent disposal, mining, and manufacturing industry [1,2].Among the heavy metals in the environment, copper (Cu) is a significant inorganic chemical of concern, owing to its widespread distribution and high toxicity

Zinc is used in alloys with copper to create a harder metal known as brass. In galvanization, zinc coats iron by oxidizing to form a protective layer of zinc oxide (ZnO) that protects the iron from oxidation. Zinc oxide is much safer than lead oxide, and it is often used in white paint. Since 1982, zinc has been the main metal used in American
