Soil Effect data sets
Extensive chronic soil toxicity data sets exist for soil microbial processes, plants, and invertebrates. Many individual NOEC/EC10values were screened for quality and relevancy, which resulted in a data set of high quality data that covered many different species. The selected data set covers different families, different trophic levels and feeding patterns for invertebrates, and microbial activities. Chronic toxicity data for individual species were generated in many different soils, enabling a toxicity comparison between soils and the establishment of toxicity soil-type models.
Data for different microbial processes are available, with NOEC/EC10values range from 28 mg Ni/kg for nitrification to 2491 mg Ni/kg for respiration. Additional data are available for enzyme activity measured in soil, with NOEC/EC10values ranging from 7.9 mg Ni/kg for dehydrogenase to 7084 mg Ni/kg for arylsulfatase activity. Data also exist for the growth of different microbial species, with EC10values ranging from 13 mg Ni/kg forAspergillus clavatusto 530 mg Ni/kg forTrichoderma viride.
NOEC/EC10values are available for different plant species, ranging from 10 mg Ni/kg for Spinacea oleraceato 1303.2 mg Ni/kg for Zea mays.
Chronic data are available for different species of soil invertebrates, including both soft- and hard-bodied invertebrates. NOEC/EC10values range from 31 -1,783mg Ni/kg for reproduction by the springtailFolsomia candidata..
Acute toxicity LC50values for soil macroinvertebrates range from 52 mg Ni/kg dw forLumbicis terrestris(mortality) to 2,500 mg Ni/kg dw forCaenorhabditis 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.
