“…Therefore, the emission reduction effect of biochar cannot be reflected in all types of greenhouse gases, and blind application may cause negative effects, so the biochar–greenhouse gas interaction should be considered in the field application of biochar. Meanwhile, other research has indicated that biochar can inhibit the efficacy of soil pesticides and their biodegradation effects [ 123 ], which makes the ability of agricultural weeding and insecticides unable to achieve the expected effects. The residue of pesticides may be related to the strong adsorption and binding capacity of biochar.…”

Soil contamination by heavy metals threatens the quality of agricultural products and human health, so it is necessary to choose certain economic and effective remediation techniques to control the continuous deterioration of land quality. This paper is intended to present an overview on the application of biochar as an addition to the remediation of heavy-metal-contaminated soil, in terms of its preparation technologies and performance characteristics, remediation mechanisms and effects, and impacts on heavy metal bioavailability. Biochar is a carbon-neutral or carbon-negative product produced by the thermochemical transformation of plant- and animal-based biomass. Biochar shows numerous advantages in increasing soil pH value and organic carbon content, improving soil water-holding capacity, reducing the available fraction of heavy metals, increasing agricultural crop yield and inhibiting the uptake and accumulation of heavy metals. Different conditions, such as biomass type, pyrolysis temperature, heating rate and residence time are the pivotal factors governing the performance characteristics of biochar. Affected by the pH value and dissolved organic carbon and ash content of biochar, the interaction mechanisms between biochar and heavy metals mainly includes complexation, reduction, cation exchange, electrostatic attraction and precipitation. Finally, the potential risks of in-situ remediation strategy of biochar are expounded upon, which provides the directions for future research to ensure the safe production and sustainable utilization of biochar.

“…The effect of biochar and AMF on simazine leaching was determined according to the method of Jones et al (2011) and Cheng et al (2017). Briefly, approximately 5.0 g from each replicate treatment was placed into the barrel of individual 25 ml syringe (20 mm diameter).…”

“…It is considered an emerging technology for carbon sequestration, mitigation of climate change, soil improvement, crop productivity enhancement and environmental remediation (Atkinson et al, 2010;Ippolito et al, 2012;Lehmann & Joseph, 2009;Maraseni, 2010;Spokas et al, 2012). Once incorporated into soil, biochar has been shown to alter soil properties (Kuppusamy et al, 2016), improve nutrient retention (Camps Arbestain et al, 2014), decrease greenhouse emissions (Chang et al, 2016) and increase sorption of contaminants (Cheng et al, 2017;Williams et al, 2015). It is well known that biochar application can increase the sorption of simazine in soil, thus decreasing its risk of leaching and direct uptake by plants.…”

“…Although these benefits of biochar have been confirmed in recent studies, there are several potential negative implications, hazards and even risks to soil and water quality that other researchers have highlighted (Graber et al, 2012;Kookana, 2010;Kookana et al, 2011;Kuppusamy et al, 2016). For example, some studies have reported that biochar inhibits simazine biodegradation (Cheng et al, 2017;Jones et al, 2011) and reduces simazine efficacy for controlling weeds or killing pests (Graber et al, 2012;Kookana, 2010;Kuppusamy et al, 2016;Nag et al, 2011;Safaei Khorram et al, 2018;Yang et al, 2006). If biochar results in a longer half-life of pesticides in the soil, then greater concentrations will accumulate in the topsoil where it is at risk of losses to water via leaching and overland flow.…”

“…However, the constant and excessive addition of herbicides can negatively impact the environment on different levels, mainly through the progressive accumulation and persistence of xenobiotics in natural environments (Hashmi et al 2017;Pinochet et al 2018). The herbicide simazine (2-chloro-4,6-bis (ethylamino)-s-triazine) is a widely used selective, systemic s-triazine, which has been broadly applied to control broadleaved weeds and annual grasses that affect various crops (Cheng et al 2017). Such widespread use affects non-target terrestrial and aquatic environments (Martínez-Iñigo et al 2010).…”

The aim of this research was to investigate the effect of applying sewage sludge combined with wheat crop residue as an organic amendment on the dissipation rate of simazine spiked at 2 and 20 mg kg −1 in an Andisol soil from southern Chile. Changes in some soil enzymes related to soil quality were measured by spectrophotometry, simazine dissipation rates were measured by gas chromatography, and biomass production in the contaminated soil was evaluated. Results of this study indicated that application of the organic amendment inoculated with Trametes versicolor enabled a decrease in negative effects of the herbicide on soil enzymatic activities and a reduction in final concentrations of simazine (~80% at both doses). The simazine half-life time was reduced from 14 to 10 days and from 36 to 15 days for doses of 2 and 20 mg kg −1 , respectively. These findings prove that the combined strategy of biostimulation and bioaugmentation using these residues can be effectively used to reduce residue pesticides in soils, mainly by increasing the microbiological activity, thus improving simazine dissipation in an Andisol soil.
