Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Effect data sets: Extensive chronic soil toxicity data sets exist for soil microbial processes, plants, and invertebrates. More than 250 individual NOEC/EC10 values were screened for quality and relevancy, which resulted in a data set of 173 individual high quality data that covered 42 different species. The selected data set covers 8 different families, different trophic levels and feeding patterns for invertebrates, and microbial activities. Chronic toxicity data for individual species were generated in 16 different soils, enabling a toxicity comparison between soils and the establishment of toxicity soil-type models.


Data for 12 microbial processes are available, with NOEC/EC10 values range from 28 mg Ni/kg for nitrification to 2,491 mgNi /kg for respiration. Additional data are available for enzyme activity measured in soil, with NOEC/EC10 values ranging from 7.9 mg Ni/kg for dehydrogenase to 7,084 mg Ni/kg for arylsulfatase activity. Data also exist for the growth of 13 individual microbial species, with EC10 values ranging from 13 mg Ni/kg for Aspergillus clavatus to 530 mg Ni/kg for Trichoderma viride.


NOEC/EC10 values are available for 11 plant species, ranging from 10 mg Ni/kg for Spinacea oleraceato 1,127 mg Ni/kg for Hordeum vulgare


Chronic data are available for 6 different species of soil invertebrates, including both soft- and hard-bodied invertebrates. NOEC/EC10 values range from 36 mg Ni/kg for reproduction by the springtail Folsomia candidato 1,140 mg Ni/kg for reproduction by the earthworm Eisenia fetida.

Acute toxicity LC50values for soil macroinvertebrates range from 52 mg Ni/kg dw for Lumbicis terrestris (mortality) to 2,500 mg Ni/kg dw for Caenorhabditis elegans (mortality).  


The acute EC50 (4 d) values for terrestrial plants range from ≥54.5 mg/kg soil d.w. to ≤1928.2 mg/kg for root elongation forHordeum vulgare.
