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.

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.

Ambient Air Quality Standards

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.

The ambient air quality data for particulate matter as well as criteria of gaseous pollutants were assembled during December 2013 to December 2015 from the Continuous Air Quality Monitoring Station (CAMS) located at Agrabad, Chittagong. The observation showed that during April- October, 24 hour average concentration of PM10 and PM2.5 were within the National Ambient Air Quality Standard (NAAQS) level but it increased occasionally by more than two and a half times during the whole non-monsoon period (November-March). The highest values found of PM2.5 were 321.1 µg/m3 in January, 2013 and 220.34 µg/m3 in December 2015. Whether, the highest alarming concentration of PM10 was reported as 474 µg/m3 in January 2007. The other gaseous pollutants such as SO2, NO2, O3, CO and Hydrocarbons remain well within the permissible limit except dry non-monsoon period. The yearly average increase of Air Quality Index (AQI) value indicates the growth rate of air pollution in Chittagong city. The main responsible pollutant for air pollution is found PM2.5.
