Lignin phenols and amino sugars within the MAOM fraction were analysed to clarify the MAOM formation pathways and their potential contributions to MAOM formation. The results demonstrated that both meadow and peat wetland restoration enhanced MAOM sequestration. Compared to grazed sites, restored meadow wetlands significantly increased the mineral-associated organic carbon (MAOC) content in soils but not the C content of the MAOM fraction; restored peat wetlands increased the C content of the MAOM fraction by 58% but not the MAOC content in soils. Notably, plant-derived C and microbial necromass C strongly and dominantly influenced the C content of the MAOM fraction in the meadow (path coefficient = 0.73) and peat wetlands (path coefficient = 0.75), respectively. Compared with those in the grazed peat wetlands, the MAOM fraction in restored peat wetlands contained 1.93, 1.61, and 2.09 times higher total, bacterial, and fungal necromass C contents, respectively. Moreover, soil properties influence lignin phenols and necromass C in conjunction with the C content of the MAOM fraction rather than directly.

To improve the efficiency of terpenes removal, which constitute a significant part of VOCs, pure cultures of microorganisms dominating in its microbiota were isolated from the microbial community of the biofilter, which has been cleaning such emissions for a long time. Seven pure cultures were isolated and then tested for being able to grow on a mineral medium in the presence of terpene vapor as the only source of carbon and energy. Three of the most actively growing cultures were selected, characterized and identified by the 16S rRNA gene as <em>Rhodococcus erythropolis</em> CA1, <em>Rhodococcus pyridinivorans</em> CA3 and <em>Gordonia</em> sp. CA6. Three identical laboratory biofilters (BF) were inoculated with a mix of these cultures to test the possibility of more complete removal of terpenes. Biofilters were adapting to clearing the model mix of terpineols and geraniol vapors for 45 days. During 45 days the purification efficiency of the model mix reached an average of 91.5% with a contact time (CT) of 3.7 ± 0.2 s and the terpene vapors concentration of 14 ± 2 mg m⁻³. Then the biofilters number BF2.1 and BF3.1 were connected to real emission from composting OFMSW. The biofilter BF2.1 purified the emission directly, whereas BF3.1 purified similar discharge after the intermediate biofilter of the 1st stage of purification (BF0.0). The BF1.0 was left connected to purification of the model mix as a control. The effectiveness of biofiltration of hard-to-remove terpenes was evaluated by gas chromatography of samples taken at the inlet and outlet of biofilters. The average efficiency of removing terpenes from real emissions by BF2.1 was 93.1 % (CT = 5.5 s). The total efficiency of removing terpenes by (BF0.0 + BF3.1) complex was 93.2 % (total CT = 7.4 s). A study of the microbiota of inoculated biofilters after 60 and 90 days of purification the real emission by cultivation from dilutions, identification by the 16S rRNA gene and fingerprinting showed that in BF2.1 and BF3.1 <em>Rhodococcus erythropolis</em> CA1 and <em>Rhodococcus pyridinivorans</em> CA3 were preserved among living cells at a level of 6.5–12.4 %, and genetically fully corresponded to the original cultures. These results could have a positive impact on improving the results of deodorization of emissions from OFMSW composting by biofiltration, simplifying the design of the biofiltration facility (one stage instead of two) and reducing the total time for effective biofiltration. This, in turn, would contribute to the wider introduction of highly efficient emission purification methods at OFMSW composting facilities in order to create more comfortable and ecologically clean environmental conditions around them.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"372 ","pages":"Article 123162"},"PeriodicalIF":8.0,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142646404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings demonstrated that the bacterial communities and ARG profiles in the plastisphere were markedly distinct from those in the surrounding water. Specifically, thirteen opportunistic pathogens and forty subtypes of ARGs, primarily related to multidrug, bacitracin, and β-lactam resistance, were identified in the plastisphere. Notably, polyethylene exhibited four times more specific ARG subtypes than polypropylene. Procrustes analysis combined with network analysis indicated a lack of strong correlation between ARG abundance and bacterial populations, suggesting potential horizontal transfer of ARGs within the microbiota of the plastisphere.

However, the increasing presence of waterbirds in rice fields is exacerbating human-wildlife conflicts, as birds are seen as pests by farmers due to the damage they perceive the birds inflict to the crops. To tackle this situation, farmers use dissuasion methods like propane gas cannons, but its effectiveness in reducing damage is often not quantified. In this study we evaluate the cost-effectiveness of propane gas cannons in deterring waterbirds from rice fields and test if there is a correlation between bird abundance in a given field during rice growth and rice yield in the same field. Waterbird counts were conducted before and after dissuasion actions targeting Glossy ibis and White stork in a major rice production area in Portugal. To assess the potential magnitude of damage reduction gained through dissuasion, we estimated the time elapsed between dissuasion events and the reestablishment of bird numbers in the disturbed fields. The economic cost of dissuasion was compared with the estimated gains from reduced damage. Results showed that on average, waterbird numbers recovered ca. 30 min after dissuasion, leading to an estimated 0.78% reduction in crop damage. The final yield of rice production was modelled considering all gains and costs involved in dissuasion actions in relation to an increase in dissuasion efforts for 11 scenarios of potential waterbird damage (0–20%). For dissuasion to be cost-effective, waterbirds would need to destroy at least 17% of the crops, far more than any damage previously recorded in Europe. Also, we found that the abundance of waterbirds in a rice field does not affect rice yield. We suggest that efforts to reduce damage should shift to more cost-effective and environmentally friendly methods, such as diversionary fields or economic compensations to farmers. This can enhance the economies of rice-dependent countries and reduce conflicts, ultimately reconciling rice agriculture with biodiversity conservation.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"372 ","pages":"Article 123369"},"PeriodicalIF":8.0,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142646165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
