This study systematically investigates the stereoselective metabolism and residue behavior of chiral pesticide prothioconazole enantiomers during the steaming, baking, and frying of steamed buns, bread, and deep-fried dough sticks. The results show that steaming, baking, and frying can significantly promote the degradation of the prothioconazole enantiomers. In lowand high-concentration treatments, the degradation rates of prothioconazole enantiomers were over 96.0% and 45.4%, respectively, and the residual concentration of prothioconazole-desthio enantiomers was less than 32.7 μg/kg (excluding fried processing). During the processing of steamed buns, bread, and deep-fried dough sticks, the enantiomer fraction (EF) value of the prothioconazole enantiomer was close to 0.5, and the stereoselectivity was not significant. During the processing of steamed buns (low concentration), bread (low and high concentrations), and deep-fried dough sticks (low concentration), the stereoselectivity of prothioconazole-desthio was significant, and preferential enantiomer degradation occurred. Following the analysis of 120 flour product samples, the residual risk.

“…Acute tests, probably due to their faster, cheaper, and in general easier protocols, have been employed more often than chronic tests, basically applying the immobilization test in the microcrustacean Daphnia magna , , mortality tests in the earthworm Eisenia andrei , the annelid worm Enchytraeus crypticus , and the springtail Folsomia candida − as well as the inhibition of bioluminescence in Vibrio fischeri . Chronic assays so far applied include reproduction tests in the same organisms used for acute determinations, and metabolic alterations in the fish Oreochromis aureus ; ,, similarly, phytotoxicity determined by germination tests in the plant Lactuca sativa has been seldom applied. ,,,, Alternative approaches such as the use of pesticide toxicity index (PTI), which employs ecotoxicological parameters from aquatic indicator species (i.e., vascular and nonvascular plants, invertebrates, and fish) rather than direct tests, have been used to determine detoxification of BPS effluents. As expected, the usefulness of these benchmark organisms depends on the functional nature of the pesticides removed in the BPS; i.e., the daphnids are expected to be more sensitive to insecticides, and the phytotoxicity tests are more appropriate for herbicides.…”

Point source contamination with pesticides is likely to occur at the farm level when pesticide-containing residues are not properly handled. To address this issue, biopurification systems (BPSs) were developed as a biotechnological approach for the on-farm treatment of pesticide-containing wastewater of agricultural origin. Despite the high removal capacity demonstrated toward diverse pesticides, BPSs have not been successful in eliminating some active ingredients, particularly from very persistent chemical groups. Moreover, the assessment of BPS efficiency has barely included an ecotoxicological evaluation, a key factor in terms of bioremediation. Proper optimization of BPS regarding the design of enhanced biomixtures (biological active matrix of BPSs) and the assessment of their behavior during real pesticide application cycles are required before massive field implementation; furthermore, specific biomixtures and operational recommendations should be applied for each crop/pesticide application cycle. This Review discusses several of these topics, including (i) pesticide removal scope; (ii) ecotoxicological monitoring of BPSs; (iii) biomixture optimization and enhancement by bioaugmentation approaches; (iv) the use of BPSs for the disposal of antibiotics and the effects of these compounds on pesticide removal; (v) unsolved operational guidelines like the BPS's life span and disposal of spent biomixtures.

Imidacloprid, a neonicotinoid insecticide is used widely in agricultural fields to control insect pests. It exhibits insecticidal property by blocking the insect nicotinic acetylcholine receptors (nAChRs). However, its excessive use over the decades has become hazardous to the living beings and environment. Thus, it is crucial to find out an efficient and effective way for the elimination of imidacloprid from the environment. To meet this requirement, scientists across the world are working on various remediation approaches such as physical (adsorption), chemical (oxidation, hydrolysis, illumination) and biological (microbial degradation). This review focuses on various approaches for the elimination of imidacloprid from the environment and also highlights the associated merits and demerits. The review will pave the way for the scientific community to develop more simple and eco‐friendly approaches for imidacloprid elimination.
