Contaminant Sensitivity of Freshwater Mussels ACUTE TOXICITY OF COPPER, AMMONIA, AND CHLORINE TO GLOCHIDIA AND JUVENILES OF FRESHWATER MUSSELS (UNIONIDAE)
The objective of the present study was to determine acute toxicity of copper, ammonia, or chlorine to larval (glochidia) and juvenile mussels using the recently published American Society for Testing and Materials (ASTM) Standard guide for conducting laboratory toxicity tests with freshwater mussels. Toxicity tests were conducted with glochidia (24to 48-h exposures) and juveniles (96-h exposure...
متن کاملThe effect of natural dissolved organic carbon on the acute toxicity of copper to larval freshwater mussels (glochidia).
The present study examined the effect of dissolved organic carbon (DOC), both added and inherent, on Cu toxicity in glochidia, the larvae of freshwater mussels. Using incremental additions of natural DOC concentrate and reconstituted water, a series of acute copper toxicity tests were conducted. An increase in DOC from 0.7 to 4.4 mg C/L resulted in a fourfold increase (36-150 µg Cu/L) in the 2...

متن کاملBiological Synthesis of Copper/copper Oxide Nanoparticles
Metal nanoparticles have gained significant interest in the past decade because of their unique physio-chemical properties which has a potential to be used in a wide range of applications. Recent efforts have gained success in synthesising nanoparticles with excellent shape and size control; however they are largely restricted to chemical methods. There is an increasing focus on eco-friendly ‘g...
متن کاملToxicity of manufactured copper nanoparticles - A review
The health effects of nanoparticles (NPs) are raising considerable and growing concerns from the public and government around the world. Nano-metals are new forms of metal with special properties, but are characterized by having a particle size of less than 100 nm. Copper is an essential trace element and its deficiency leads to different diseases in humans. In gen...
