“…Emerging replacement/alternative chemicals, NBFRs and CPs, have been globally mass-produced and used (especially in Asia), , resulting in their higher occurrence in these soils, since they have only recently been restricted. Despite the global restriction, some OCPs are still in use across South Asia (notably India) . Driven by the Indian monsoon, these POPs will enter the Tibetan region via air mass movement and accumulate in soils following deposition …”

“…Therefore, the distribution of these legacy POPs is more dependent on the soil OC pool. With mass manufacture and use in the regions bordering the TP, the distribution of some POPs, notably OCPs, was also affected by the monsoon from these areas, overlaying cumulative atmospheric deposition to the soil with trace levels of these compounds. Additionally, the lack of correlation could be related to the relatively low concentrations of some compounds in the soil samples (e.g., low amounts of DeBDEs reaching remote soils due to its high molecular weight/low volatility and limited LRAT) …”

“…Despite the global restriction, some OCPs are still in use across South Asia (notably India). 50 Driven by the Indian monsoon, these POPs will enter the Tibetan region via air mass movement and accumulate in soils following deposition. 51 In regions devoid of direct contamination by POPs, the soil's capacity for accumulation emerges as a pivotal determinant shaping the distribution and concentration of these pollutants.…”

Persistent organic pollutants (POPs) tend to accumulate in cold regions by cold condensation and global distillation. Soil organic matter is the main storage compartment for POPs in terrestrial ecosystems due to deposition and repeated air−surface exchange processes. Here, physicochemical properties and environmental factors were investigated for their role in influencing POPs accumulation in soils of the Tibetan Plateau and Antarctic and Arctic regions. The results showed that the soil burden of most POPs was closely coupled to stable mineral-associated organic carbon (MAOC). Combining the proportion of MAOC and physicochemical properties can explain much of the soil distribution characteristics of the POPs. The background levels of POPs were estimated in conjunction with the global soil database. It led to the proposition that the stable soil carbon pools are key controlling factors affecting the ultimate global distribution of POPs, so that the dynamic cycling of soil carbon acts to counteract the cold-trapping effects. In the future, soil carbon pool composition should be fully considered in a multimedia environmental model of POPs, and the risk of secondary release of POPs in soils under conditions such as climate change can be further assessed with soil organic carbon models.

“…In situ bioremediation comprises the treatment and elimination of the contaminated material at the site, whereas, in ex-situ, the contaminated are treated somewhere else. bioventing, bioleaching, biostimulation, land farming, composting, bioaugmentation, rhizofilteration, and phytoremediation are a few examples of bioremediation technologies [1][2][3][4][5] . Biodegradation and bioremediation are similar methods up to an extent since both of these approaches employ microorganisms for the alteration or breakdown of pesticides.…”

Bioremediation of organic compounds and heavy metals has been recognized to be a successful and effective technique in rhizoremediation of soil toxicity using the beneficial microbes which produce different metabolites and enzymes to degrade the toxic compounds/ pesticides available in the soil. In the present study, actinobacterial isolates were explored and identified for bioremediation of soil toxicity available in the soil. The actinobacterial isolates were utilized for the promising PGPR traits and ability to degrade the monocrotophos pesticide residues available in the soil. The "opd" gene of interest responsible for monocrotophos pesticide degradation trait was isolated and cloned in vector DNA to produce recombinant DNA. The recombinant DNA was transformed in E. coli cells to produce multiple copies in E. coli cells resulting in recombinant (transformed) and non-recombinant (non-transformed) colonies. The transformed E. coli cells were inoculated in nutrient broth having pesticide concentration. The transformed cells degraded the pesticide, and the HPLC method determined the derivatives produced. The formulations based on actinobacterial isolates were tested, and field applications were done to determine the reduced soil toxicity, if any, observed.

“…HFLPME using the HF device is an excellent selection for sample preparation of real samples with a high matrix. An HF as an extraction device protected the extraction solvent from contaminants with interfering spices and led to better selectivity of the method [23,24]. Besides, HF is a low-cost disposal tool that eliminates the memory effects.…”

A novel and minimized sample preparation technique based on hollow fiber-protected liquid-phase micro-extraction has been developed for the extraction of three organochlorine pesticides, including Endrin, Chlordane, and Dieldrin from rice samples followed by gas chromatography-mass spectrometry (GC-MS) detection. Single-walled carbon nanotube (SWCNT) and a proper ionic liquid (IL) were ultrasonically dispersed and injected in the lumen of hollow fiber as the extraction phase for preconcentrating and extracting the target analytes from the rice samples. Effects of type of nanoparticles, ILs, and desorption solvent in the extraction efficiencies of the analytes were investigated by one factor at a time approach. In addition, other parameters influencing the extraction procedure were optimized using an experimental design method to decrease the number of experiments, reagent consumption, and cost. Under the optimized conditions, the limits of detection and quantification for determining three organochlorine pesticides were varied between 0.019–0.029 and 0.064–0.098 ng.mL− 1, respectively. The calibration graphs were linear over the concentration range of 0.064–13.2, 0.098–16.7, and 0.092–11.4 ng.mL− 1 for measuring Endrin, Chlordane, and Dieldrin in the rice samples, respectively. The relative standard deviations for inter-day and intra-day analysis were lower than 7.06 and 4.75% for the triplicate determination of three organochlorine pesticides. Besides, the relative recoveries and standard deviations of Endrin, Chlordane, and Dieldrin for analyzing several Iranian rice samples were between 86.0-92.9% and 4.5–5.8%, respectively. The results were compared with other similar works in literature, proving that the proposed method is reliable and valuable for routine monitoring of the organochlorine compounds in food samples.
