Further data
LDLo 1389 mg/kg oral, r a t .
The following applies to soluble iron compounds: nausea and vomiting after ingestion. The absorption of large quantities is
followed by cardiovascular disorders. Toxic effect on liver and kidneys.
12. Ecological information
Adverse ecological effects cannot be excluded in the event of improper handling or disposal.
Further ecological data:
The following applies to dissolved iron compounds in general: fish: toxic from 0.9 mg/l up at pH 6.5-7.5; lethal from 1 mg/l up
at pH 5.5-6.7; 50 mg/l iron upper limit for fish life. When iron ions flocculate in an alkaline medium, mechanical damage
occurs in aquatic organisms.
