Additional information
COPPER IODIDE
The environmental hazard associated with copper iodide is assessed in terms of the toxicity of copper and iodide ions released during dissociation of the compound in the aqueous phase.
Summary information on the short-term toxicity of copper and iodide ions to aquatic invertebrates is presented below.
COPPER:
See summary aquatic effects
IODINE:
Short term toxicity to aquatic invertebrates:
LC50 (48 hours): 0.55 mg/L (Daphnia magna)
Key value for Chemical Safety Assessment:
EC50/LC50 for freshwater invertebrates: 0.55 mg/L.
Discussion:
One short term toxicity study to aquatic invertebrates (Daphnia magna) has been identified for iodine. This is a 48 hour study under static, non aerated conditions that investigated the toxicity of iodine to Daphnia magna (toxicity to rainbow trout was also separately investigated in the same publication). [Laverock, MJ Stephenson, M and Macdonald CR (1995)]. The study also investigated whether the chemistry of the water used in the studies affected the toxicity results.
The test guidelines cited for the conduct of the study were the Ontario Ministry of the Environment Guidelines. The information reported in the publication is broadly comparable with OECD Guideline 202 Daphnia sp., Acute Immobilisation Test. Although there are some deficiencies in the study and the information reported, these are not considered to significantly affect the overall reliability or validity of this study. An overall reliability score of 2 (reliable with restrictions) is considered appropriate.
The 48 hour LC50 for I2 (elemental iodine) is 0.59 mg/L (standard Winnipeg River treatment) and 0.55 mg/L (high water hardness sample; Milner Ridge Spring) The LC50 using the high water hardness sample is selected as the endpoint for this study as the water hardness of the culture and dilution water adheres to the range in OECD Guideline 202.
