PM2.5 particulate matters were collected in Taiyuan from November 2012 to October 2013. The total concentrations of seven kinds of typical heavy metal element (Fe, Pb, Mn, Cu, Ni, Cr, Cd) in particles were quantified by acid digestion method, then determined by flame atomic absorption spectrophotometer. The results showed that the concentration of PM2.5 in Taiyuan was six times higher than the Ambient Air Quality Standard (GB 3095-2012) II, and the atmospheric particles in Taiyuan are high in Fe, Pb, Cu, Mn, followed by Ni, Cr, Cd. The concentrations of Fe, Cd, Cu, Mn, Ni, Cr in industrial area were high, while the contents of Pb was high in commercial area, all of them were low in educational and residential area.

The present study deals with the assessment of ambient air quality with respect to Total Suspended Particulates (TSP), Respirable Suspended Particulate Matter (PM10), Sulphur dioxide (SO2) and Nitrogen dioxide (NO2) considered over a period of two years from Sep 2010 to Aug. 2012. Air quality index are used for local and regional air quality management in many cities of the world. The air quality index has been determined at three different sites i.e. PTC (SI), Buddh Bazar (SII) and Mughalpura (SIII) of Moradabad city. The experimental results obtained from the different air quality categories according to national ambient air quality standard at different site as PTC (SI) though looks a clean area, falls under moderate pollution category with 68.78 index value. This may be due to fossil fuel combustion at the outskirts of the parade grounds and burning of dry leaves inside the area. Buddh Bazar (SII) which is a commercial area falls under high air pollution category with 99.48 index value. This site near railway station is extremely congested resulting in slow movement of vehicles, long waits at the signals and a large number of vehicles running during the day and night time. Mughalpura (SIII) is an industrial area, falls under the very high pollution category with 120.99 index value, may be due to the industrial activities i.e. mainly brasswares. Five heavy metals i.e. Cu, Zn, Fe, Cd and Pb were also observed at all the sites. Among the metals highest concentration of Zn was recorded at almost all the sites whereas Cu, Zn and Fe was found higher at industrial site, may be attributed to melting of Brass sillies to prepare the different Brassware items.

Air particulate matter (PM) level and its constituents (black carbon, organic carbon and selected trace metals) were investigated from samples of a field campaign from Tajgaon Industrial area in Dhaka City.  The sampling was done from November 2006 to April 2007 using MiniVol Portable AirMetrics samplers. The samples were collected in two fractions of 0-2.5 µm and 0-10 µm sizes using two samplers simultaneously.  It has found that both PM10 and PM2.5 values were higher than the 24-h average Bangladesh national ambient air quality standard. From statistical analysis of the PM composition data coupled with reconstructed mass (RCM) technique, five major local sources could be identified those contributing to PM mass. Although PM samples were collected from an industrial area, vehicular emissions constituted the major source of air pollution and possibly some regional emission sources are also responsible for high PM2.5 and BC concentrations in Dhaka, especially during wintertime. It is also observed that PM2.5, PM10 and BC concentration levels at a receptor site largely depend on the meteorological conditions including rainfall, wind speed and wind direction.

Ozone Precursor

High concentrations of ground-level ozone have been observed during wintertime in the Uinta Basin of western Utah, USA, beginning in 2010. We analyze existing ozone and ozone precursor concentration data from 38 sites over 11 winter seasons and conclude that there has been a statistically significant (p < 0.02) decline in ozone concentration over the previous decade. Daily exceedances of the National Ambient Air Quality Standard for ozone (70 ppb) have been trending downward at the rate of nearly four per year. Ozone and NOx concentrations have been trending downward at the rates of about 3 and 0.3 ppb per year, respectively. Concentrations of organics in 2018 were at about 30% of their values in 2012 or 2013. Several markers, annual ozone exceedance counts and median ozone and NOx concentrations, were at their largest values in the period 2010 to 2013 and have never recovered since then. We attribute the decline to (1) weakening global demand for oil and natural gas and (2) more stringent pollution regulations and controls, both of which have occurred over the previous decade. We also see evidence of ozone titration when snow cover is absent.

According to the information of air quality which published by the urban air quality real-time publishing platform, the concentration characteristics of PM10 and PM2.5 were studied in Kunming (KM), Changsha (CS), Hangzhou (HZ), Shanghai (SH), Harbin (HEB), Beijing (BJ), Wuhan (WH) and Guangzhou (GZ). The results show that the concentrations of PM10 and PM2.5 exceeded the Ambient Air Quality Standard (GB3095-2012) in varying degrees in March, 2013. The concentrations of PM10 in Wuhan is the highest, reached 164μg/m3, exceeded the standard by 9.3%; the concentrations of PM2.5 is much higher in Wuhan, Changsha and Beijing, the average concentrations were 96μg/m3, 103μg/m3 and 110μg/m3, exceeded the standard by 28.0%, 37.3% and 46.7% respectively. The correlation of PM10 with PM2.5 in most of these cities was good in March. The correlation analysis of pollutant with meteorological factor in Hangzhou, Shanghai, Beijing and Guangzhou was also studied, the results show that the concentrations of PM10 and PM2.5 are weakly positive correlation with temperature in the four cities, negative correlation with relative humidity without Beijing, and negative correlation with wind speed.

The purpose of this research are to analysis air quality and dust impact to people that came from factory activities at residential area around factory location of PT. Semen Padang. Measuring of air quality conducted in 3 residential area that are Komplek RW 1, RT 3 Batu Gadang district, Perumnas Indarung RW. VII, and housing of UNAND Blok D Gadut, using Personal Dust Sampler. The result is respirable dust concentration at housing complex RW. 1 RT. 3 Batu Gadang district that is 0,33 mg/m, the Perumnas Indarung RW.VII that is 0,55 mg/m along with housing of UNAND Blok D Gadut that is 0,44 mg/m. Concentration of dust respirable at all are still below ambient air quality standard that exist on PP RI No. 41 Tahun 1999, 3 mg/m. Based on quesioner and puskesmas data proximate with use univariat analysis, negative impact who feels people are impact of health is eyes irritation disease and impact of environment especially community-owned material. Keywords: air quality, negative impact, residential area, respirable dust, PT. Semen Padang ABSTRAKPenelitian ini bermaksud untuk menganalisis kualitas udara dan dampak negatif yang dirasakan masyarakat dari debu yang berasal dari aktivitas pabrik di kawasan perumahan sekitar lokasi pabrik PT. Semen Padang. Pengukuran kualitas udara dilakukan di 3 kawasan perumahan yaitu komplek perumahan RW. 1 RT. 3 Kelurahan Batu Gadang, Perumnas Indarung RW. VII, dan Perumahan UNAND Blok D Gadut dengan menggunakan alat Personal Dust Sampler. Diperoleh hasil konsentrasi debu respirable pada komplek perumahan RT.3 RW.1 Kelurahan Batu Gadang sebesar 0,33 mg/m, pada Perumnas Indarung RW.VII sebesar 0,55 mg/m serta pada Perumahan UNAND Blok D Gadut sebesar 0,44 mg/m. Konsentrasi debu respirable pada ketiga lokasi masih berada di bawah ambang batas baku mutu udara di lingkungan, 3 mg/m. Berdasarkan kuesioner dan data puskesmas terdekat dengan menggunakan analisis univariat, dampak negatif yang dirasakan masyarakat adalah dampak terhadap kesehatan berupa penyakit iritasi mata dan dampak terhadap lingkungan khususnya pada kondisi material yang dimiliki masyarakat.Kata kunci: kualitas udara, dampak negatif, kawasan perumahan, debu respirable, PT.
