Increased mechanization has generated noise and vibration problems in opencast mines. Noise isgenerated by every activity or machinery present in the mines. Artificial Neural Network (ANN)and Adaptive Network-based Fuzzy Inference System (ANFIS) was applied to predictmachinerynoise in a mechanized opencast coal mine. This paper dealt with comparison of theprediction capabilities of ANN and ANFIS based soft computing models vis-Ã -vis existingstatistical model (ENM) in order to find the actual noise status in an opencast coal mine. From thepresent study, it could be concluded that ANFIS gave better prediction results than the ANN (MLPand BP) methods. This paper also includes the preparation of a noise map in the opencast mine usingtwo methods (Kriging and IDW) and ArcGIS.

The Industrial (MIDC) area of Badlapur and Dombivli have around 870 chemical and dyesmanufacturing Industries, these industries release numerous air pollutants in surroundingenvironment. This air pollutant content is required to be below the standard norms given byNAAQS. Ambient air monitoring station of MPCB monitors the Sulfur dioxide (SO2), Oxides ofNitrogen (NOx), and Respirable Suspended Particulate Matter (RSPM) regularly in the area. Theassessment was done at three sites, BIWA house Badlapur, CETP and MIDC Dombivli for theduration of three years from January 2018 â December 2020. Results obtained from the study haveshown that RSPM level of all the stations were decreased several fold amidst lockdown comparedto the previous years. The level of Sulfur dioxide and Oxides of Nitrogen were also drasticallydeclined during the lockdown period. Hence the Air Quality Index (AQI) recorded at all threestations is satisfactory to moderate for the year 2020.

Although the direct impact of COVID-19 is on human health, it has substantial impacts oneconomic, social, cultural and environmental issues. The priority of the international efforts was to find a vaccine for COVID-19. The impacts on other sectors, such as medical waste management,have not been given the same attention, especially in Jordan. The purpose of this paper is todetermine the impact of COVID-19 on medical waste management in Jordan. The studyinvestigated the amount of waste generated in 2018 and 2020 in 54 facilities that generate medicalwaste. The results showed that the governmental implementations and curfew period havesignificant impacts on the amount of medical waste. The hospital that treats COVID-19 patients,private hospitals and institutions, showed an increase in the quantity of medical waste while thegovernmental hospitals, health care centers, laboratories, and industries showed a decrease inwaste generation during the year 2020. In some months, the amount of waste from COVID-19hospitals increased up to 3 folds in 2020 compared with 2018 data. Health care centers, labs,institutions and industries generated zero waste during the curfew period. It was recommended tokeep control and inspection on medical waste streams to avoid illegal disposal, or poor handlingand transportation measures.

Traffic and industrial emission generate air pollutants which have been associated with respiratoryhealth symptoms of human beings. Although there is positive association between air pollutionand respiratory health, but the degree of association among different seasons varies due to thecomposition of different air pollutants. Present studies have been carried out to monitor and recordthe particulate and gaseous air pollutants (PM2.5, PM10, NO2 and SO2) in ambient air at IndraChowk, Gajraula (U.P.) during winter and rainy seasons. The level of PM2.5, NO2 and SO2 had beenfound significantly higher during winter as compared to the rainy season. Due to higher level ofair pollutants in ambient air, the incidence of respiratory diseases increased in winter seasons. Thesymptoms of cough, phlegm, headache and eye irritation had been found significantly higher inthe road-side venders during winter months as compared to other seasons of the year. However,their blood oxygen saturation had been recorded significantly higher during the rainy months.

In this study, we used the directed acyclic graph (DAG) to analyze a dataset of PM2.5 concentrationlevels in 11 cities in Southeastern Asian countries for the period of March 18 to April 11, 2021. Thisis the period that PM2.5 posted a major problem for several cities in Southeast Asia. We analyzedthe data to determine the effect of the PM2.5 concentration in each city on that of each of the othercities. The results show that the PM2.5 concentration in Yangon, Myanmar, had a direct effect onthe PM2.5 concentration in Chiang Mai, Thailand, and that the PM2.5 concentration in KualaLumpur, Malaysia, had a direct effect on the PM2.5 concentration in Singapore, Republic ofSingapore. Where one country has a direct effect on another, a reduction or increase of PM2.5 in theformer will reduce or increase, respectively, the PM2.5 concentration in those on which it has aneffect. Given this relationship, if the concentration of PM2.5 is to be reduced either overall or in anyspecific country is to be reduced, international cooperation will be essential. Our application ofDAG to this environmental issue exemplifies the viability of this technique for exploring andindicating solutions for real-world problems more generally.

We analyzedthe data to determine the effect of the PM2.5 concentration in each city on that of each of the othercities. The results show that the PM2.5 concentration in Yangon, Myanmar, had a direct effect onthe PM2.5 concentration in Chiang Mai, Thailand, and that the PM2.5 concentration in KualaLumpur, Malaysia, had a direct effect on the PM2.5 concentration in Singapore, Republic ofSingapore. Where one country has a direct effect on another, a reduction or increase of PM2.5 in theformer will reduce or increase, respectively, the PM2.5 concentration in those on which it has aneffect. Given this relationship, if the concentration of PM2.5 is to be reduced either overall or in anyspecific country is to be reduced, international cooperation will be essential. Our application ofDAG to this environmental issue exemplifies the viability of this technique for exploring andindicating solutions for real-world problems more generally.","PeriodicalId":20370,"journal":{"name":"Pollution Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49191504","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}
