Additional information
Results from calculated classification (using mixture toxicity rules) are supported (WoE) by additional consideration from physico-chemical properties of the UVCB substance.
Chemistry of the substance (see IUCLID section 4.23 chemical and mineralogical characterization) confirms presence of species that trigger hazard. Substance is a solid, in pasty form when handled but powder when dried (see picture in IUCLID section 1.4 "sampling protocol") which particle size distribution (IUCLID section 4.5) for a worst case sample (ie material was dried) confirmed powder form. Water solubility (IUCLID section 4.8) furthermore demonstrated that substance is poorly soluble in water, with the exception of Cu, As, Ni, and S (ie sulphates)
Effects on skin irritation/corrosion: irritating
Effects on eye irritation: irritating
Effects on respiratory irritation: irritating
Justification for classification or non-classification
- Please refer to IUCLID section 13 for detailed MeClas printouts with the specified input concentrations and resulting classification. Please visit www.meclas.eu for more information about the tool. MeClas tool version used: 2.5
