A comprehensive study on the air quality was carried out in four locations namely, Tiruchengode Bus Stand, K.S.R College Campus, Pallipalayam Bus Stop and Erode Government Hospital to assess the prevailing quality of air. Ambient air sampling was carried out in four locations using a high volume air sampler and the mass concentrations of PM10, PM2.5, SO2, NOX and CO were measured. The analyzed quality parameters were compared with the values suggested by National Ambient Air Quality Standards (NAAQS). Air quality index was also calculated for the gaseous pollutants and for Particulate Matters. It was found that PM10 concentration exceeds the threshold limits in all the measured locations. The higher vehicular density is one of the main reasons for the higher concentrations of these gaseous pollutants. The air quality index results show that the selected locations come under moderate air pollution.

Abstract The paper aims to estimate the tCO2e from flare stack sites in the Eastern zone of Nigeria and review air monitoring done at the flare sites with the objective of establishing a model for gas tCO2e emission and gaseous pollutants. It focuses on the South-Eastern region of Nigeria where oil and gas production are being carried out (Imo and Abia states). It zero-in on the hydrocarbon processing and handling facilities (flowstation) and the gas flared volumes. The study was carried out using representative data from an onshore flowstation in Eastern Nigeria. The data consist of gas flared volumes from year 2013-2017 and ambient gaseous emission from air quality report done on the same location. Univariate regression and correlation using Excel were carried out on yearly average ambient air quality parameters (VOC, NOx, CO, SOx, CH4, SPM, NH3, H2S) to check the statistical significance of each parameter as an independent variable and calculated tCO2e as the dependent variable. Excel Muti-variate linear regression method was then used to generate a predictive model for tCO2e and gaseous emission parameters. It presented a relationship between the emission from flared gas and air quality index.

Environmental standards of Japan are reviewed and compared with United States' standards. Ambient air quality standards for criteria pollutants, water quality (stream quality) standards, and the effluent standards for wastewater discharges are compared. From this study, it is understood that some standards are more stringent in Japan while others are more stringent in the U.S. Comparisons are made for several water quality and air quality parameters which provide some understanding of the level of environmental compliance that may be required of a typical Japanese shipyard.

This paper analyzes the improvement of ambient air quality indicators by monitoring the NOx concentration in one of the most polluted areas of Bucharest, using the statistical method "SIX SIGMA" (6σ). By applying the methodology of this statistical approach, the aim is to reduce non-conformities within the specified limits (according to the standards and legislative norms in force) and respectively, to ensure maximum efficiency (99,99%), equivalent to a yield of 3.4 defects per million opportunities (DPMO). As high concentrations of air pollutants have a major impact on human health, the most harmful effect has been found to be caused by nitrogen dioxide (NO2), mainly from ground-level ozone. Using the "6σ" method, the optimal solutions for eliminating non-conformities and implicitly for reducing the NO2 concentration and ensuring the improvement of the ambient air quality can be identified.

ABSTRAKPenelitian ini bekerja sama dengan Dinas Lingkungan Hidup (DLH) Kota Cimahi dalam rangka pengendalian pencemaran udara di kota tersebut mengingat perkembangan Kota Cimahi yang terus mengalami perkembangan. Analisis kualitas udara dilakukan di laboratorium PT. Unilab Perdana yang telah mendapatkan akreditasi oleh KAN No. LP-195-IDN. Pengambilan sampel dilakukan pada tanggal 15 September 2017 sedangkan untuk analisis di laboratorium di lakukan pada tanggal 15 sampai dengan 27 September 2017. Parameter yang dianalisis yaitu SO2, CO2, NO2, O3, HC, PM10, PM2,5, Pb, NH3, dan H2S. Pengambilan sampel kualitas udara dilakukan secara langsung di lapangan di 8 titik. Berdasarkan hasil penelitian di Kota Cimahi kualitas udara masih tergolong baik hal tersebut terlibat bahwa parameter kualitas udara ambien masih memenuhi baku mutu sesuai PP 41/1999 tentang PPU. Upaya pengendalian pencemaran udara harus terus dilaksanakan mengingat angka penyakit ISPA di kota ini yang menempati posisi tertinggi dibandingkan dengan penyakit lainnya.ABSTRACTThis research is in collaboration with the Environmental Agency (DLH) of Cimahi City in order to control air pollution in the city due to the development of Cimahi City. Air quality analysis was carried out in the laboratory of PT. Unilab Perdana which has been accredited by KAN No. LP-195-IDN. Sampling was carried out on 15 September 2017 while the analysis in the laboratory was conducted on 15 to 27 September 2017. The parameters analyzed were SO2, CO2, NO2, O3, HC, PM10, PM2,5, Pb, NH3, and H2S . Air quality sampling is carried out directly in the field at 8 points. Based on the results of research in Cimahi City, air quality is still relatively good, it is involved that ambient air quality parameters still meet the quality standards according to PP 41/1999 concerning PPU. Air pollution control must continue to be carried out considering the number of lung infection diseases in this city which occupies the highest position compared to other diseases.

The outbreak of novel coronavirus (COVID-19) pandemic forced affected countries to implement strict lockdown to contain the spread of this disease before the advent of the vaccine. This containment resulted in social and economic crisis globally. This study evaluated the impact of COVID-19 on three “P” s of sustainability (Planet, People, and Profit) in India. A comparative analysis was conducted by evaluating the available secondary data in different sectors during the pre-lockdown and lockdown period. Seven major air quality parameters: particulate matter (PM2.5 and PM10), nitrogen dioxide (NO2), sulfur dioxide (SO2), ammonia (NH3), carbon monoxide (CO), and ozone (O3) were studied in six states of India to review the ambient air quality status. Stratified random sampling technique was used in this study for collective portrayal of the country’s air quality. A drastic cutback of the level of PM2.5 and PM10 with significant increase of O3 was observed in the lockdown phase for most of the selected monitoring stations. A significant change in level of PM2.5 and PM10 was observed when t-test was performed in between the pre-lockdown and lockdown period. Improvement of ambient air quality was also observed considering the air quality index (AQI) during lockdown. The trend and volatility of two broad Indian stock market indices, SENSEX and NIFTY-50, were analyzed, and results showed that both the indices have recovered during the forty-day lockdown phase. The potential effects of the crisis on various sectors of Indian economy were assessed in this study, and a set of policy recommendations for these sectors were suggested.
