“…The EC50 value calculated from the model was 1.59 mg kg −1 , which was lower than another EC50 (3.26 mg kg −1 ) based on the reproduction of soil animal Folsomia candida stressed by soil Hg (Lock and Janssen 2001). According to the previous report (Fountain and Hopkin 2005), the F. candida was very sensitive to the soil pollution and used as indicator to assess soil quality.…”

Purpose Experiments were conducted to examine the effects of mercury (Hg) on soil nitrification activities and the microbial communities of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA). Methods The soil samples spiked with different Hg concentrations were incubated for a period of 1, 2, 4, and 8 weeks in triplicate and the potential nitrification rate (PNR) of the samples was determined. The abundance of AOB and AOA was measured after an 8-week incubation by real-time polymerase chain reaction (PCR) assay of the amoA genes, while the community compositions by cloning and sequencing approaches. Results The soil PNR differed with different incubation periods. It tended to decrease with increasing soil Hg concentrations at week1, basing on which the half-maximal effective concentration (EC50) was 1.59 mg kg −1 . There was no significant difference in the abundance of AOB or AOA among the treatments. The AOB community was dominated by Nitrosospira-like sequences and more than 70% of the obtained clones were affiliated with the cluster 3a.2. The percentage of cluster 3a

“…Ni is an essential element for organisms, but excess Ni in soil can exert toxic effect on soil biota and expose indirectly risks to human beings Berton et al 2006;Fargasova 2008;Lock and Janssen 2002). Efforts have been made to investigate the Ni toxicity thresholds in European soils using various toxicity assays including barley root elongation (Rooney et al 2007) and microbial assays (Oorts et al 2006(Oorts et al , 2007.…”

Purpose Deriving toxicity thresholds through bioassays has become the scientific basis for the risk assessment of metal contamination in soils, but few studies have been reported for Ni toxicity in Chinese soils. In addition, although leaching has been recommended to increase the ecological relevance of the output of soil toxicity bioassays, its impacts on Ni threshold and soil solutions in soils remained to be shown. Therefore, in this study, 17 soils were collected throughout China and were assessed for Ni toxicity using substrate-induced nitrification (SIN) assay for both un-leached and leached treatments. Meanwhile, soil solutions of all Ni treatments were extracted and analyzed. This study provides information for the development of a terrestrial biotic ligand model (TBLM) for Ni in Chinese soils.Materials and methods Soils were artificially amended with NiCl 2 solution to generate nominal Ni contamination levels, and aliquot of each Ni treatment was leached with artificial rain to prepare leached soil samples. All the 17 unleached and the 17 leached soils were subjected to the standard SIN protocol. A total of 816 microcosm tubes were established. Soil solution was extracted, and the solution physiochemical properties were analyzed for each Ni treatments. Both the total-Ni-based and the solution-Nibased median effective concentrations (EC50) in unleached soils and leached soils were calculated from dose-response curves. Free-Ni 2+ -based EC50 was also calculated based on solution chemical properties. Leaching effect was assessed based on these results. Results and discussion Ni EC50 varied largely among soils for both the total-Ni-based and the solution-Ni-based EC50 in un-leached soils. In un-leached soils, the total-Ni-based EC50 values ranged from 52.8 mg kg −1 (Hulunber soil) to 2,385.4 mg kg −1 (Wulumuqi soil), and the solution-Nibased EC50 ranged from 0.70 mg L −1 (Jiaxing soil) to 293.35 mg L −1 (Wulumuqi soil). Stepwise multiple regressions showed that soil pH and total Ca were the best predictors for the total-Ni-based EC50. Protective effects of Ca 2+ and Mg 2+ but not H + against Ni toxicity in soil solution were found. Leaching impacted Ni EC50 differently among soils, with leaching factor ranging from 0.2 (Haikou soil) to 19.7 (Hulunber soil) for the total-Ni-based EC50 and from 0.1 (Dezhou soil) to 35.7 (Jiaxing soil) for the solution-Ni-based EC50. In addition, predictability of Ni EC50 was higher in leached soils. The variations in Ni EC50 were in agreement with the findings in previous studies. Soil pH and Ca may play important roles in the partition of Ni in Chinese soils and thus impact the Ni toxicity. Protective effects of Ca 2+ and Mg 2+ in soil solutions against Ni toxicity may exist, but the role of H +

“…This effect can be attributed to the removal of excess Ni, salts, and protons in soil solution (Oorts et al 2007). On the other hand, freshly spiked soil with a series of Ni concentrations was applied to test the Ni toxicity threshold to F. candida, by which a relatively lower EC 50 of QY soil but a higher EC 50 of DZ soil were obtained compared to that by a previous study (347 to 671 mg/kg) (Lock and Janssen 2002). This could be explained by the fact that these tested soils had different Ni bioavailability, which depends on soil properties to a great extent.…”

“…Most of the ecotoxicological assessment of Ni has been carried out by laboratory incubations with test organisms using Ni-spiked soils. The toxicity of Ni to plants (Thakali et al 2006a;Li et al 2011), microbes (Oorts et al 2007), invertebrates (Lock and Janssen 2002;Thakali et al 2006b;Rudel et al 2013), and recently, macroinvertebrates (Peter et al 2014) in the soil provides valuable data for terrestrial ecological risk assessment of Ni. Accordingly, some empirical models have been developed to predict Ni bioavailability and toxicity to plants and invertebrates based on the different soil properties (e.g., Rooney et al 2007;Smolders et al 2009).…”

Metal aging in soils has been considered an important factor influencing its availability and toxicity to organisms. In this study, we report the influence of 5 years field aging on the nickel (Ni) toxicity to collembolan Folsomia candida based on two different types of soil from Dezhou (DZ) and Qiyang (QY) counties in China. Acute and chronic toxicity of Ni to F. candida was assessed in both freshly spiked and field aging contaminated soils. We found that 5 years field aging increased the EC 50 and 2d-LC 50 values of Ni to F. candida in the DZ soil, while little influence on the Ni toxicity was observed in the QY soil. There was no adverse effect of the long-term field aging on the Ni toxicity to the survival of F. candida in the two tested soils. In addition, field aging of the two soils impacted differently the water-soluble Ni concentrations, which were significantly correlated to the juvenile production of F. candida based on a logistic model. Our study highlights different effects of long-term field aging on the Ni toxicity to F. candida between divergent types of soil, and this should be taken into account in future toxicity testing and risk assessment practices.
