“…Similarly, when several plant species or plant community composition, or different species management were manipulated in a single study, we considered them as multiple outcomes from the same elevated CO 2 experiment. When pollutants were manipulated in addition to the CO 2 treatment, we extracted the data from the treatment with no pollutant (e.g., cadmium (Jia et al, 2021), chlorpyrifos (Kollah et al, 2019) or tropospheric ozone (Kanerva et al, 2006)). Data were extracted for the control and the elevated CO 2 treatments (when several elevated levels of CO 2 were manipulated, data were extracted for each high CO 2 treatment, see Maxwell et al, 2022).…”

Global change may have profound effects on soil nitrogen (N) cycling that can induce positive feedback to climate change through increased nitrous oxide (N2O) emissions mediated by nitrification and denitrification. We conducted a meta‐analysis of the effects of elevated CO2 on nitrification and denitrification based on 879 observations from 58 publications and 46 independent elevated CO2 experiments in terrestrial ecosystems. We investigated the effects of elevated CO2 alone or combined with elevated temperature, increased precipitation, drought, and N addition. We assessed the response to elevated CO2 of gross and potential nitrification, potential denitrification, and abundances of related functional genes (archaeal amoA, bacterial amoA, nirK, nirS, and nosZ). Elevated CO2 increased potential nitrification (+28%) and the abundance of bacterial amoA functional gene (+62%) in cropland ecosystems. Elevated CO2 increased potential denitrification when combined with N addition and higher precipitation (+116%). Elevated CO2 also increased the abundance of nirK (+25%) and nirS (+27%) functional genes in terrestrial ecosystems and of nosZ (+32%) functional gene in cropland ecosystems. The increase in the abundance of nosZ under elevated CO2 was larger at elevated temperature and high N (+62%). Four out of 14 two‐way interactions tested between elevated CO2 and elevated temperature, elevated CO2 and increased precipitation, and elevated CO2 and N addition were marginally significant and mostly synergistic. The effects of elevated CO2 on potential nitrification and abundances of bacterial amoA and nirS functional genes increased with mean annual temperature and mean annual precipitation. Our meta‐analysis thus suggests that warming and increased precipitation in large areas of the world could reinforce positive responses of nitrification and denitrification to elevated CO2 and urges the need for more investigations in the tropical zone and on interactive effects among multiple global change factors, as we may largely underestimate the effects of global change on soil N2O emissions.

“…However, our current review shows that it is almost of common use nowadays, making precedent approaches almost obsolete, mainly because of its unprecedented sensitivity. Indeed, NGS, besides revealing the effectiveness of the applied pesticide on its target, may also reveal the unintended impact of pesticide through screening of non-target groups present in soil (e.g., impact of insecticide on bacteria, herbicide, on fungi) (Kollah et al, 2019;Mallet et al, 2019). In addition, it also has the potential to reveal crucial information regarding the presence and activity of microbial degraders of pesticides and other contaminants in the soil for remediation purposes (Jeffries et al, 2018).…”

“…Although extensive researches have been rendered on the harm of widespread organophosphorus and pyrethroid compounds on the human and animal health and also their remediation from soil or water, but only a few of these investigations have focused on their impacts on the soil microbial diversity (Wu et Chlorpyrifos inhibits the soil microbial nitri cation process which results in less movement and transport of mineral nitrogen because of higher NH 4 /NO 3 ratio in soils caused by retardation of nitri cation (Kollah et al 2019). It was found that the physiochemical properties of soil changed the toxicity of the CP and DM for the soil fauna (Jaabiri Kamoun et al 2018).…”

Pesticides and insecticides are the chemicals widely used in the agricultural industry, but their ecotoxicological effects on the environment are not still well understood. In this study, the remediation of chlorpyrifos (CP) and deltamethrin (DM) and their impacts on soil microbial diversity was investigated. Four different soils with various salinity (0%, 1%, 2% and 4%) were artificially contaminated by CP and DM. Then, natural attenuation of the pesticides in soil microcosms and their effects on soil microbial composition were studied by metagenomics. The pesticide natural attenuation analysis showed higher CP remediation in slightly saline soils with 1% and 2% salinity and faster removal of DM in 1% saline soil in comparison to non-saline control microcosm. The complete natural attenuation of the contaminants took around 60 days. The metagenomics analysis indicated that pesticide contamination had significant impacts on the soil flora and some dominant species in the control microcosm were completely eliminated by CP and DM. In addition, Paenibacillus (2% salinity and DM), Bacillus (4% salinity and CP), Paeniclostridium (1% salinity and DM) and Lachnospiraceae (1% salinity and CP) were the dominant genus by 77%, 50%, 41% and 39% relative abundances, respectively. At phylum level, the sequences belonged to Firmicutes, Proteobacteria, Bacteroidetes and Actinobacteria were considerably enriched during natural attenuation of both DM and CP pesticides. Furthermore, Shannon and Simpson Indexes were identified more sensitive to the microbial community evenness, while, Chao1 and ACE indexes were changed by the community abundance. It was revealed that the highest negative impacts of deltamethrin and chlorpyrifos on the culturable and unculturable communities were related to the non-saline soil.
