“…Our previous studies reported that exposure to BDE209 and/or Pb had detrimental influences on earthworms (Zhang et al, 2014b(Zhang et al, , 2014c(Zhang et al, , 2015dLi et al, 2015). However, these reports were basically depended on a step rather than repetitive treatment.…”

“…In order to determine exposure concentrations, based on previous toxicity evaluation about the two chemicals, we had carried out some preliminary experiments (Zhang et al, 2014b(Zhang et al, , 2014c(Zhang et al, , 2015dLi et al, 2015).…”

“…In order to determine exposure concentrations, based on previous toxicity information about these compounds, we had carried out some preliminary experiments [21][22][23][24]. Selected Pb exposure concentration (250 g of Pb g −1 of soil -abbreviated to Pb) corresponded to the grade II trigger value of the Chinese environmental quality standard.…”

“…The metal-rich granules (pellet fraction) (fraction D) were subsequently separated from tissue fragments and cell membranes (cell debris) (fraction E) by centrifugation at 10,000 × g for 10 min at 11 • C. All fractions were freeze-dried for Pb analyses. The total and subcellular Pb concentrations in earthworms were analyzed by atomic fluorescence spectrometer (AFS-9130, Beijing Titan Instruments Co., Ltd., Beijing, China) according to the method described by our previous studies [22,24]. The Pb contents were expressed as g g −1 fresh weight.…”

“…However, most of the knowledge on the toxicity of the two pollutants to earthworms is based upon the effects of a single compound. Our previous studies have evaluated the biochemical and physiological impacts of Pb and BDE209 on E. fetida [21][22][23][24]; while to our best knowledge, the interactive effects of both chemicals on histopathological and gene transcription changes in earthworms have rarely been assessed.…”

Nanomaterials have increasingly gained a great amount of interest due to their widespread applications, while their potential impacts on invertebrates in soil lack thorough investigation. This study is mainly aimed at determining the acute and subacute toxicity to the earthworm Eisenia fetida, induced by different levels of nanoscale zerovalent iron (nZVI) (100, 500, 1000 mg kg) in natural soils. The results showed that compared to the controls, exposure to 500 and 1000 mg kg of nZVI significantly (P < 0.05) inhibited growth and respiration and increased avoidance response in earthworms. The perturbations of antioxidant enzyme activities (superoxide dismutase-SOD and catalase-CAT), malondialdehyde (MDA) content, and reactive oxygen species (ROS) clearly revealed that oxidative stress was induced in E. fetida exposed to nZVI. Good correlations were observed in current results among the growth, respiration, MDA, and ROS (R > 0.8; P < 0.05), and that ROS was the most sensitive parameter in response to the stress caused by nZVI. Additionally, the histopathological examination of transverse sections of the exposed earthworms passing through the body wall illustrated that there was a serious injury in epidermal tissue after an exposure of 28 days. These findings will provide a comprehensive understanding of toxicological effects of nZVI in a soil-earthworm system.
