The need to find new sources of NR is increasing rapidly due to challenges from climate change and environmental impacts. NR from <i>Taraxacum kok-saghyz</i> (TKS) is a promising alternative. To compete with the pricing of NR from the rubber tree, an economically viable extraction system with a high output of NR is needed. The mechanisms involved in the separation of rubber from other plant constituents and potential rubber agglomeration during mechanical extraction processes are described through experimental results but not as extraction models. To analyze these mechanisms, two different wet-mill extraction system setups are investigated in this study: single-stage extraction and two-stage extraction with premilling. Two extraction models for mechanical rubber extraction mechanisms are identified and described: (i) the Model of Rolling Shear Mechanism with mild extraction behavior and rubber agglomeration, and (ii) the Model of Abrasion Shear Mechanism, which limits the rubber yield and promotes fast rubber agglomeration. The insights into the mechanisms are described and discussed through sieve analysis, rubber yield, dirt content, microscopic analyses, and viscoelastic analyses of the extracted rubber.</p>","PeriodicalId":93846,"journal":{"name":"ACS agricultural science & technology","volume":"4 5","pages":"524–534"},"PeriodicalIF":0.0,"publicationDate":"2024-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140716506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A stereomicroscope and Fourier transform infrared spectroscopy were used to measure the physical and chemical properties of the MPs. The outcome showed the omnipresence of MPs in Surat city’s soil, with an average abundance of 103.2 ± 57.28 particles 100 g^–1. Over 90% of all MPs were made of polyethylene (70.19%), polypropylene (17.53%), and poly(ethylene terephthalate) (6.92%) polymers. The white/transparent-colored MPs having a size of about 2–5 mm are predominantly available. The principal component analysis (PCA) results indicate that the discovered MPs in the soil samples are mostly represented by fragments and fibers, which account for 52.90% of the total variance in the data set. Additionally, in the current research, the ecological risk assessment of MPs in soil, the pollution load index (PLI), the polymer hazard index (PHI), and the ecological risk index (ERI) of MPs were studied. The PLI values greater than 1 were observed, indicating that all sampling sites were polluted with MPs. Based on the abundance, type of polymer, and toxicity of MPs found in the soil sample, an evaluation concluded that there is a moderate to medium ecological risk associated with MPs polluting the city soil. The greatest PHI value in this study is 239.69 (risk category: medium), while the lowest PHI value is 8.69 (risk category: low). The greenness profile of the method was assessed using the software-based analytical greenness metric (AGREE) tool. The developed approach is partially green, as shown by an AGREE metric score of 0.53. The present investigations emphasize the critical importance of taking action in metropolitan areas such as Surat to mitigate MP pollution and improve waste management practices for a greener and cleaner ecosystem in the future. These findings will inspire the creation of ecofriendly alternatives crucial for reducing plastic consumption, safeguarding ecosystems, and mitigating MPs’ impact on the soil quality.</p>","PeriodicalId":93846,"journal":{"name":"ACS agricultural science & technology","volume":"4 5","pages":"614–625"},"PeriodicalIF":0.0,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140720911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we use the Agricultural Policy/Environmental eXtender model (APEX) to quantify reductions in pesticide losses via runoff and erosion for common mitigation measures. These measures are currently being considered for the protection of listed species in the United States (i.e., vegetative buffers, contour cropping, planting of cover crops, and no-till practices). Analyses were conducted for two pesticides, atrazine and pendimethalin, for each of the two crop groups, corn, and vegetables/ground fruits. Separate analyses were conducted for different hydrologic regions, in which these crops are grown in the United States. Our results indicate that the effectiveness of the runoff mitigation measures, whether singly or in combination, varies with pesticide, crop, and region. We also found that there are diminishing returns as more mitigations are added to the analysis.
