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
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 forSpinacea
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
range from 31
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
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
