“…Generally, single toxicity test of chlorpyrifos and Cr 6+ on earthworms was carried out, and the effect of different drugs on the mortality of earthworms was recorded. Similar result was also reported before (Oliveira et al, 2018). The order of toxicity of two drugs on earthworms was obtained: chlorpyrifos > Cr 6+ , and the toxicity increased with the extension of exposure time.…”

Eisenia fetida are commonly used for water and soil ecotoxicology tests. Here, we use Eisenia fetida as a model organism to investigate the effect of cartap and Cr 6+ on the physiological and biochemical indicators, such as mortality, protein content, superoxide dismutase (SOD), catalase (CAT) and malondialdehyde (MDA). The results showed that with an increasing content of cartap, protein contents in Eisenia fetida increased in the beginning, then decreased, and finally stabilized after prolonged exposure. In the case of increasing Cr 6+ , protein contents in Eisenia fetida decreased in the beginning, then increased, and finally decreased after prolonged exposure. The SOD activity in Eisenia fetida was simulated under low concentration and short durations of contaminations, while the SOD activity decreased after prolonged exposure. Meanwhile, under low contaminations, CAT contents were stimulated. The MDA contents in Eisenia fetida were significantly negatively correlated with SOD activity. This indicated that when the organisms are subjected to pollutant stress, the activity of SOD will be rapidly induced for removing excess oxygen free radicals and producing H2O2, accompanied by enhanced activity of CAT converting H2O2 to H2O. With the prolonged exposure time, the SOD activity decreased, and the organisms were harmed by oxidative damage with enhanced MDA contents.

“…These analyses are based on the application of representative in vitro and in vivo models that provide information about the potential hazards that a contaminated site may represent for the human health and for the environment. Therefore, the toxicity associated to different real polluted soils was reported in previous works using several model organisms such as earthworms (Li et al, 2020;Oliveira Resende et al, 2018), plants (Loureiro et al, 2006;Massa et al, 2018), or cell lines, being the latter exposed to contaminant extracts directly obtained from the soils (Baderna et al, 2014(Baderna et al, , 2013Husejnovic et al, 2018). Besides in contaminated soils, these assays also showed to be an appropriate approach to study the toxicity of landfill soils (Alimba et al, 2016;Swati et al, 2017), as well as in other polluted substrates such as sediments (Pinto et al, 2014a(Pinto et al, , 2014b.…”

“…Biomonitoring becomes relevant in contaminated sites as it is an indicator of ecotoxicological risk [31][32][33] . Therefore, the use of a simple bioindicator is useful to infer how it reduces the risk in the soil associated with the decrease in the bioavailability of Pb.…”

Soil contamination by Pb can result from different anthropogenic sources such as lead-based paints, gasoline, pesticides, coal burning, mining, among others. This work aimed to evaluate the potential of P-loaded biochar to remediate a Pb-contaminated soil and to apply a biomonitoring alternative after soil remediation. First, rice husk-derived biochar was obtained at different temperatures (450, 500, 550, and 600 ºC). Then, part of the resulting material was activated. Later, the raw biochars and activated biochars were immersed in a saturated KH2PO4 solution to produce P-loaded biochars. The ability of materials to immobilize Pb and increase the bioavailability of P in the soil was evaluated by an incubation test. The materials were incorporated into doses of 0.5, 1.0, and 2.0%. After 45 days, soil samples were taken to biomonitor the remediation process using two bioindicators: a phytotoxicity test and enzyme soil activity. Activated P-loaded biochar produced at 500 ºC has been found to present the best conditions for soil Pb remediation. This material significantly reduced the bioavailability of Pb and increased the bioavailability of P. The phytotoxicity test and the soil enzymatic activity were significantly correlated with the decrease in bioavailable Pb but not with the increase in bioavailable P. Biomonitoring using the phytotoxicity test is a promising alternative for the evaluation of soils after remediation processes.
