Italy was among the first European countries to ban asbestos, with Law 257/1992, and was among the first to issue technical sector regulations for the protection of workers and living environments. The technical characteristics of this substance, together with its low cost, led to the creation of different mixtures and the processing and production of over three thousand types of products containing asbestos with content varying from 10% to 99% in weight. These products included Asbestos Cement Pipes (ACPs), used for decades for civil and military purposes. ACP are not in themselves a primary source of danger to public health when underground, intact and still in place, insofar as the main asbestos-related health risk is inhalation. Cement asbestos pipes can however generate situations of risk when they are subject to removal or maintenance that involves their partial or total exposure to ambient air with the possible dispersion of fibres into the air. The paper shows a systematic set of procedures and indications to be followed for the safe removal of underground pipes in ACM in order to ensure maximum protection of workers and the living environment surrounding the area of operations. These procedures may be subject to periodic updating on the base of feedback following their application. These procedures were developed because of the need to provide precise guidelines of national reference, due to a lack of specific sector regulations.","PeriodicalId":394576,"journal":{"name":"Proceedings of the 8th World Congress on New Technologies","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126418609","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}

Rivers are the major transport pathways of microplastics to reach the marine environment. Understanding how microplastics are distributed horizontally and vertically in rivers is a requirement to assessing the risks associated with microplastic abundance. This study aims to investigate the effect of flow characteristics on the transport of microplastics and identify transport of these particles mechanistically between a tributary and main stream of the Ergene River, Turkey using mass-balance and hydrodynamic equations. For this purpose, Corlu tributary of the Ergene River was chosen as the study area. River samples were collected from the six stations of the Ergene River including Corlu tributary and upstream and downstream of the outfall of this tributary in September 2020. Fifteen litres of water sample were collected from the water surface of each sampling station using stainless-steel buckets and transferred to glass bottles. Additionally, the parameters including flow rate (m s -1 ) and stream depth (m) of the river were measured using Acoustic Doppler Current Profiler instrument. After removing organic matter, the collected water samples were filtered onto a plankton mesh with 45 µm pore size. Microplastic particles were visually identified under stereo-microscope (Olympus SZX 16, 30x) and transferred to a clean cellulose filter paper, previously checked for airborne contamination. Microplastic particles were photographed and counted by the help of ImageJ software.","PeriodicalId":394576,"journal":{"name":"Proceedings of the 8th World Congress on New Technologies","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126598524","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}

However, most current models simulate disease spread on a more generalized scale, lacking specificity for localities such as towns or counties, leading to one-size-fits-all policies being instituted on the country or state-wide-level. However, localities differ in many social determinants of health, which impact disease dynamics therefore necessitating models tailored to individual locations. This research aims to answer this question: What local factors affect COVID-19 outbreak severity and intervention effectiveness? To do this, a novel agent-based disease model was created using NetLogo to simulate contextualized COVID-19 disease dynamics at the local level. Model inputs include population demographic composition, area size, vaccination ratio, interventions (mask, test-and-isolate, or lockdown), and compliance rate. Agents representing the simulated local population are assigned specified traits, and become \"susceptible”, \"exposed”, \"infected”, \"recovered”, \"quarantined”, or \"dead” as they interact with other agents. The model was validated using data from state and local health agencies for Westchester County, NY (84.2% accuracy). A sensitivity analysis demonstrated that a higher elderly population, a lower young population, a lower vaccination rate, and weaker interventions were all factors that increased outbreak severity. A comparison of selective localities representing metric axes of high/low age and high/low vaccination was conducted for four different U.S. counties and showed that 1) any intervention would dramatically reduce locality variations and 2) interventions have higher impact in higher risk localities. This model enables local officials to better focus limited resources when making health related decisions, and a website (www.localcovidmodel.org) has been created for model access. © 2022, Avestia Publishing.
