“…In contrast to photolysis, the biodegradation of imidazolinones is significantly accelerated in the presence of both BCs, although RH-BC has a greater impact. The effects of other BCs derived from rice straw (RS), corn straw (CS), chicken manure (CM) and tire rubber (TR) on the dissipation of the fungicide cyazofamid and its metabolite CCIM (4-chloro-5-p-tolylimidazole-2-carbonitrile) have been assessed by Tang et al [158]. Cyazofamid dissipation is either accelerated or depressed, depending on BC type, application rate, and soil moisture.…”

“…The residual amounts of metabolite CCIM increase by 8-15 times after BC application, regardless of BC type and cyazofamid dissipation. Tang et al [158] provided new insights into BC application for soil remediation and highlighted the potential risk of the build-up of metabolites in BC-amended soil, especially when the metabolites have higher toxicities than the parent compound.…”

Effect of Organic Residues on Pesticide Behavior in Soils: A Review of Laboratory Research

The management of large volumes of organic residues generated in different livestock, urban, agricultural and industrial activities is a topic of environmental and social interest. The high organic matter content of these residues means that their application as soil organic amendments in agriculture is considered one of the more sustainable options, as it could solve the problem of the accumulation of uncontrolled wastes while improving soil quality and avoiding its irreversible degradation. However, the behavior of pesticides applied to increase crop yields could be modified in the presence of these amendments in the soil. This review article addresses how the adsorption–desorption, dissipation and leaching of pesticides in soils is affected by different organic residues usually applied as organic amendments. Based on the results reported from laboratory studies, the influence on these processes has been evaluated of multiple factors related to organic residues (e.g., origin, nature, composition, rates, and incubation time of the amended soils), pesticides (e.g., with different use, structure, characteristics, and application method), and soils with different physicochemical properties. Future perspectives on this topic are also included for highlighting the need to extend these laboratory studies to field and modelling scale to better assess and predict pesticide fate in amended soil scenarios.

“…Biochar in a combination of metal nanoparticles are also known to have immense application in the area of remediation [ 166 ]. Biochar had been reported for remediation of soil contaminated with pesticides such as imazapyr, chlorpyrifos, and thiamethoxam [ 167–169 ]. Sometimes, a very high sorption capacity of biochar is observed so that a higher level of pesticide accumulation is observed [ 45 , 170 ].…”

Bioengineered biochar as smart candidate for resource recovery toward circular bio-economy: a review

Biochar’s ability to mediate and facilitate microbial contamination degradation, as well as its carbon-sequestration potential, has sparked interest in recent years. The scope, possible advantages (economic and environmental), and future views are all evaluated in this review. We go over the many designed processes that are taking place and show why it is critical to look into biochar production for resource recovery and the role of bioengineered biochar in waste recycling. We concentrate on current breakthroughs in the fields of engineered biochar application techniques to systematically and sustainable technology. As a result, this paper describes the use of biomass for biochar production using various methods, as well as its use as an effective inclusion material to increase performance. The impact of biochar amendments on microbial colonisation, direct interspecies electron transfer, organic load minimization, and buffering maintenance is explored in detail. The majority of organic and inorganic (heavy metals) contaminants in the environment today are caused by human activities, such as mining and the use of chemical fertilizers and pesticides, which can be treated sustainably by using engineered biochar to promote the establishment of a sustainable engineered process by inducing the circular bioeconomy.

“…So far, numerous researchers have studied the changes of pesticide residues in wine processing [31][32][33]. To our knowledge, many studies have reported on the residues of cyazofamid and its metabolite, CCIM, in the field [10,11,34], but little attention has been paid to the change in their residue levels caused by the process of wine-making. In order to guarantee food safety for consumers, we utilized grapes harvested in the field to carry out wine-making processing experiments.…”

The Dissipation of Cyazofamid and Its Main Metabolite CCIM during Wine-Making Process

Few studies have focused on the residues of cyazofamid and its main metabolite CCIM (4-chloro-5-p-tolylimidazole-2-carbonitrile) in the wine making process, which is crucial to evaluate the potential food risk of cyazofamid and CCIM. In this work, detailed study has been conducted on the evaluation of the fate of cyazofamid and its main metabolite CCIM during the wine-making process. The targeted compounds cyazofamid and CCIM were separated and determined by high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS) and processing procedure including washing, peeling, fermentation, and clarification. Results showed that residues of cyazofamid and CCIM decreased significantly in wine processing. The dissipation of cyazofamid in the fermentation process followed the first-order of kinetics, and the half-life of cyazofamid was 46.2–63.0 h, whereas, the residues of CCIM, in the three treatments, decreased with time elapse. The processing factors (PFs) were all less than one in different processing processes, and the PFs ranges of cyazofamid and CCIM were 0.003–0.025 and 0.039–0.067 in three treatments in the overall process. The outcome indicated that the whole process could significantly reduce the residues of cyazofamid and CCIM in red and white wines. The results might provide more precise risk assessments of cyazofamid in the wine-making process.
