Organic additions like vermicompost can help restore and preserve the quality of the soil, however, producing vermicompost of a high enough standard is difficult. This study was planned to prepare vermicompost by utilizing two different organic wastes viz. household waste and organic residue amended with rock phosphate and further evaluate their stability and maturity indices during vermicomposting for quality of produce. For this study, the organic wastes were collected and vermicompost was prepared by using earthworm (<i>Eisenia fetida</i>) and with or without enriching with rock phosphate. Results showed that pH, bulk density, and biodegradability index were decreased and water holding capacity and cation exchange capacity was increased with the gradual progress of composting starting from 30 to 120 days of sampling/composting (DAS). Initially (upto 30 DAS) water-soluble carbon and water-soluble carbohydrate increased with rock phosphate enrichment. The population of the earthworms and enzymatic activities (CO₂ evolution, dehydrogenase, and alkaline phosphatase) were also increased on enriching with rock phosphate and with the progression of the composting period. Rock phosphate addition (enrichment) also reflected the higher content of phosphorus (106% and 120% for household waste and organic residue, respectively) in the final product of vermicompost. The vermicompost prepared from household waste and enriched with rock phosphate showed greater maturity and stability indices. Overall, this can be concluded that the maturity and stability of vermicompost depend on the substrate used and improves on enriching with rock phosphate.<i>Implications</i>: Our study concludes that the quality of vermicompost depends on different substrates, composting period, and enrichment with rock phosphate. The qualities of vermicompost were best found under household waste-based vermicompost enriched with rock phosphate. The efficiency of vermicomposting process using earthworms was found maximum for enriched and without enriched household-based vermicompost. The study also indicated that several stability and maturity indices are influenced by different parameters and hence cannot be determined by a single parameter. The addition of rock phosphate increased the cation exchange capacity, phosphorus content, and alkaline phosphatase. Nitrogen, zinc, manganese, dehydrogenase, and alkaline phosphatase were found higher under household waste-based vermicompost relative to organic residue-based vermicompost. All four substrates promoted earthworm growth and reproduction in vermicompost.</p>","PeriodicalId":49171,"journal":{"name":"Journal of the Air & Waste Management Association","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10046934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Methods are needed to ensure that PFAS are not released into the environment during their use or disposal. Alumina-based catalysts have been used for the abatement of small perfluorocarbons, e.g. tetrafluoromethane and perfluoropropane, emitted during the silicon etching process. Here, an alumina-based catalyst was tested to determine if these catalysts may facilitate the destruction of gas-phase PFAS. The catalyst was challenged with two nonionic surfactants with eight fluorinated carbons, 8:2 fluorotelomer alcohol and N-Ethyl-N-(2-hydroxyethyl)perfluorooctylsulfonamide. The catalyst helped decrease the temperatures needed for the destruction of the parent PFAS relative to a thermal-only treatment. Temperatures of 200°C were sufficient to destroy the parent PFAS using the catalyst, although a significant number of fluorinated products of incomplete destruction (PIDs) were observed. The PIDs were no longer observed by about 500°C with catalyst treatment. Alumina-based catalysts are a promising PFAS pollution control technology that could eliminate both perfluorocarbons and longer chain PFAS from gas streams.<i>Implications:</i> The release of per- and polyfluoroalkyl substances (PFAS) into the atmosphere can cause problems for human health and the environment. It is critical to reduce and eliminate PFAS emissions from potential sources, such as manufacturers, destruction technologies, and fluoropolymer processing and application sites. Here, an alumina-based catalyst was used to eliminate the emissions of two gas-phase PFAS with eight fully fluorinated carbons. No PFAS were observed in the emissions when the catalyst was at 500°C, lowering the energy requirements for PFAS destruction. This shows that alumina-based catalysts are a promising area for research for PFAS pollution controls and the elimination of PFAS emissions into the atmosphere.</p>","PeriodicalId":49171,"journal":{"name":"Journal of the Air & Waste Management Association","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10468685/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10479459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The mathematical models about quantifying resource losses were built, and then the evaluation index system of resource losses was established. More than one hundred family farms in Sichuan province and Chongqing city of China located in the subtropics were selected as research cases and were classified as small-, medium- and large-scale family farms, whose unit resource losses and resource loss rates were both evaluated by the index system. Results show that the unit resource losses and the resource loss rate of medium-scale family farms are the lowest among these three kinds of family farms. Therefore, medium-scale farms are moderate, and then are recommended for scale-breeding industries.<i>Implications</i>: Appropriate sizes are essential for the green development of scale-breeding industries. The external environment factors and internal resource effect should be considered.

Shedding trees during winter months (January - March) were selected. Most abundant trees were <i>Pongamia pinnata</i> (Indian beech), <i>Morus alba</i> (mulberry), <i>Prosopis juliflora</i> (mesquite) and <i>Kigelia africana</i> (sausage tree).

The global incidence of Severe Acute Respiratory Syndrome (SARS) epidemic in 2003, China, (Zhong et al. 2003), H1N1 influenza epidemic in 2009, Mexico, and California (USA) (Van Kerkhove et al. 2011), Middle East Respiratory Syndrome (MERS) in 2013, Saudia Arabia (Hageman 2020), the 2019 pandemic Covid-19, caused by SARS-CoV-2, China (Rothan and Byrareddy 2020), and the ongoing threat of bio-terror attack by the deliberate release of agents such as anthrax or smallpox (Taylor, Lai, and Nasir 2012), further emphasize the necessity of having a more holistic critical views on the significance of bioaerosols. It calls for the fundamental, coherent, and standardized research toward execution of the role of bioaerosols, including its interactions with other molecules, exposure, and its mechanism of action. Bioaerosols are simply defined as biological airborne particles that are temporally and spatially directly released into the atmosphere from all types of environments, including soil, freshwater, and oceans. They may originate from plants, animals, or microorganism (live/ dead bacteria, fungi and viruses) or comprise their byproducts such as fungal spores, plant pollen, various fragments and excretions (Humbal, Gautam, and Trivedi 2018). The complexity, and diversity of bioaerosols composition/shapes are also reflected into its size, which range from 0.001 to 100 μm (Kim, Kabir, and Jahan 2018). Bioaerosols form a complex mixture of particulate matter (PM) with chemical aerosols (e.g., inorganic and organic components) (Jahne et al. 2015) which impact the atmospheric chemistry and physics. They can influence the global climate system and precipitation through different mechanisms such as scattering and absorbing radiation (Després et al. 2012), cloud micro physical processes by acting as ice nuclei (Vali et al. 1976), and cloud condensation nuclei (FröhlichNowoisky et al. 2016). The dispersion and transport of bioaerosols through atmospheric long distances movement (Maki et al. 2019; Meola, Lazzaro, and Zeyer 2015; Peter et al. 2014) also generate an increase in diversity of genetic poll with the potential of the evolvement and alteration of the ecosystem’s dynamic (Burrows et al. 2009). The spread and exposure to airborne pathogen may have adverse impact on agriculture and human public health (Humbal, Gautam, and Trivedi 2018). The main categories of diseases associated with exposure to bioaerosols are: i) acute toxic effects, ii) infectious diseases, iii) respiratory diseases, and iv) cancer. Respiratory inflammation and sensitivities (i.e., asthma) are triggered and developed upon exposure to the microbial and their cellular components (e.g., pollen and fungal allergens and lipopolysaccharide) (Beck, Young, and Huffnagle 2012; Rohr et al. 2015), microorganism-deri","PeriodicalId":49171,"journal":{"name":"Journal of the Air & Waste Management Association","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9876117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 current density distribution on the surface of the collecting plate was tested on an ESP experimental setup. The effect of electrode frames on the current density distribution was also systematically investigated. The test results show that the current density distribution on the position that directly opposites the needle of RS corona discharge is much higher, on the contrary, the current density on the position that directly opposites the frames is almost zero.
