“…Luo et al [5] found that internal Pb concentrations in E. crypticus ranged from 10.4 to 776 mg Pb/kg dry body weight, with total Pb concentrations from 15 to 656 mg Pb/kg dry soil in soils from a shooting range. Santorufo et al [23] reported 17.3 mg to 300 mg Pb/kg dry body wt in E. crypticus exposed to urban soils, with total lead concentrations from 18.7 mg to 695 mg Pb/kg dry soil.…”

“…Earthworm survival has been reported to be very tolerant to lead, whereas reproduction was more sensitive [3]. The reproduction of the species Enchytraeus crypticus showed similar sensitivity to lead in field-contaminated soils from a shooting range [5].

The present study aimed to assess the bioavailability and toxicity of lead nitrate and lead chloride to Enchytraeus crypticus in a natural standard soil. Worms were exposed to Pb-spiked soil for 21 d, and survival and reproduction were related to total, 0.01 M CaCl -extractable, and porewater Pb concentrations in the soil and internal concentrations in the surviving animals. The Pb availability for Pb(NO ) and PbCl was similar, as confirmed by Langmuir and Freundlich isotherms. The Pb concentrations in surviving worms increased with increasing Pb concentrations in the soil and did not differ for the 2 Pb salts. Lead was toxic to E. crypticus at median lethal concentrations (LC50s) of 543 and 779 mg Pb/kg dry soil and median effect concentrations (EC50s) of 189 and 134 mg Pb/kg dry soil, for Pb(NO ) and PbCl , respectively. Mortality of E. crypticus was related to internal Pb concentrations in the worms rather than to total or available Pb concentrations in the soil, whereas reproduction toxicity was better explained from Pb concentrations in 0.01 M CaCl extracts or porewater of the test soil than from total Pb concentrations in the soil or Pb concentrations in the worms. Overall, the bioavailability and toxicity of Pb(NO ) and PbCl to E. crypticus in LUFA 2.2 soil did not differ. Environ Toxicol Chem 2017;36:2083-2091. © 2017 SETAC.

“…This study is part of a broader investigation that aimed at assessing the ecotoxicological risk of Pb in shooting range soils and deals with the effects on springtails; earlier studies described the effects on earthworms and enchytraeids [17,18]. Six natural field soils were collected from different landscapes (bullet plot, forest and grass lands) of a shooting field in the Netherlands, representing a gradient of Pb pollution but also different pH and organic matter contents.…”

h i g h l i g h t s• Soils from different landscapes of a shooting range are examined.• Bioavailability of Pb varies with soil properties especially, pH and OM.• Collembolan reproduction was more sensitive to pH than to Pb in soils.• Collembolans avoided acid Pb contaminated soils. a r t i c l e i n f o a b s t r a c tUnderstanding bioavailability and toxicity is essential for effective ecological assessment of contaminated soils. Total, water and 0.01 M CaCl 2 extractable and porewater Pb concentrations and soil properties in different shooting field soils were investigated. Three artificial soils containing different pH and organic matter contents and two natural soils were included as controls. Survival, reproduction and avoidance responses of Folsomia candida exposed to these soils as well as internal Pb concentrations were measured. In the shooting range soils, total Pb concentrations were 47-2398 mg/kg dw, pH CaCl 2 3.2-6.8 and organic matter content 3.8-7.0%. Pb concentrations in F. candida linearly increased with increasing Pb concentrations in the soils. Acid forest soils caused significantly higher collembolan mortality and avoidance responses and significantly lower reproduction than the neutral grassland soils, which could be attributed to differences in pH and especially CaCl 2 extractable Pb concentrations. Soil properties significantly affected bioavailability and toxicity of Pb, but overall the collembolans seemed more sensitive to pH than to Pb in soils. This study shows the importance of selecting proper reference soils for assessing the effects of field soils.

“…While the reason for the difference is not clear (Chelinho et al, 2011), other authors have demonstrated a correlation with these variables, especially for pH, conductivity, clay and sand content, and the carbon/nitrogen ratio (Chelinho et al, 2011;Luo et al, 2014;Vašíčková et al, 2015). Any lack of correlation observed might be because the selected organism can effectively survive and reproduce within the range of conditions found in the sampled points; in this case, pH values fell between 4.3-8.2, organic content measured at 1.2-42%, and clay concentrations were between 1-29% (Table 1) Soil parameters accounted for 38.0% of the overall variability.…”

“…The observed differences in vegetation cover result from the different effects that soil properties exert on living organisms (Luo et al, 2014). In secondary forests, organic matter content showed little effect when compared with those of other factors; for example, humidity and pH heavily influenced the Poduromorpha and Symphyla groups.…”

A disused electrical substation was the site of the spill of 40,000 L of Ascarel oil. However, none of the expected principal contaminants were chemically detected above established guidelines. Since the analysis of other possible contaminants is extremely expensive and impractical, the objective of this study was to indirectly evaluate possible contamination by determining the influence of physico-chemical parameters on the variation in soil mesofauna data and ecotoxicological testing. The tested substation is located in Ipanema National Forest in São Paulo State, Brazil. The area surrounding this site has several different soil uses and vegetation cover types. The square 200 m × 200 m collection area was defined by a grid comprised of 6 equally spaced lines along each axis. Soil samples were taken at each intersection save for 2, for a total of 34. Ecotoxicological testing was completed using Enchytraeus crypticus. The mesofauna was affected by multiple soil attributes that together accounted for 75.5 and 84.8% of the variability in samples taken from secondary forest and wooded pasture, respectively. However, variability in the E. crypticus testing was not strongly correlated to these physico-chemical attributes, possibly due to the tolerance of the tested species to the variations observed in this study. This provides strong evidence that no contaminants are affecting local biota. However, additional studies are needed to analyze more complex abiotic factors that might account for the observed variability.Key words: ascarel; polychlorinated biphenyls; soil biota; soil contamination Ecotoxicologia e mesofauna do solo em área com histórico de derramamento de óleo na Floresta Nacional Ipanema RESUMO: Em uma subestação elétrica ferroviária desativada houve o derramamento de 40 mil L de óleo ascarel. Entretanto não se detectou no solo a presença dos contaminantes esperados acima dos valores orientadores. Como analisar quimicamente outros possíveis contaminantes se torna altamente custoso e inviável, o objetivo deste estudo é avaliar de forma indireta a possível presença de outros contaminantes, através do poder de explicação da variabilidade de dados da mesofauna do solo e de ensaios ecotoxicológicos por parâmetros químicos e físicos do solo. A subestação está localizada na Floresta Nacional de Ipanema, em São Paulo. No local foi definido um grid de coleta de 40 x 40 m com seis linhas. A mesofauna mostrou-se influenciada por alguns atributos do solo, que em seu conjunto explicou 75,5 % da variabilidade nos pontos de floresta secundária e 84,8 % nos pontos de pasto arborizado. A variabilidade dos resultados do ensaio com E. crypticus foi pouco explicada pelas características físico-química do solo. Com isso, há fortes indícios que não há contaminantes gerando impactos na biota do solo do local. Entretanto, verifica-se a necessidade de um estudo adicional com atributos abióticos de maior complexidade como fatores explicativos da variabilidade.Palavras-chave: ascarel; bifenilas policloradas; biota do solo;...
