Ozone (O3) have many adverse impacts toward the living human, environment and O3 formed through the photochemical reaction with the aid of sunlight. Therefore, this study focused on the determination of O3, nitric oxide (NO), nitrogen dioxide (NO2) concentrations and meteorological parameters (temperature, humidity, wind speed and wind direction) three residential area namely Taman Tun Dr Ismail Jaya, Selangor as the urban area, Taman Delima, Sungai Petani, Kedah as the sub urban area and Taman Kifayah, Jeli, Kelantan as the rural area. The monitoring were continuously done for three days in 24 hours from 12 a.m. until 12 a.m. per day at each site. Aeroqual S500 series and weather station model RK900-01 were used to measure O3, NO, NO2 concentrations and meteorological parameters. The concentration of O3, NO, NO2 and the meteorological parameters were determined and O3 concentration was compared by one-way analysis of variance (ANOVA). Among the studied areas, the highest mean O3 concentration was recorded in Taman Delima, Sungai Petani with 35.2 ppb followed by Tun Dr Ismail Jaya with 33.3 ppb. Result suggested that sub urban areas showed higher mean O3 concentration compared to urban area which might linked to the availability of the O3 precursors in the area. As expected, the lowest mean O3 concentration recorded at Taman Kifayah, Jeli with 12.1 ppb as the area have limited O3 precursor’s sources. However, the ozone concentration at three residential areas were still under permissible level according to Recommended Malaysia Ambient Air Quality Guidelines (RMAAQ).

Air pollution has become a crucial problem nowadays, especially on particulate matter. Major sources of particulate matter came from transportation, while wind speed, temperature and other factors can contribute to this problem. This research focuses on the determination of levels of particulate matter at residential and educational areas in Shah Alam. Two (2) sites were chosen, namely Flat Nilam Sari that represented the residential areas while University of Selangor represented the educational areas. Four (4) sets of levels of particulate matter and other parameters (traffic volume, temperature and wind speed) were obtained by using Dylos DC1700 Laser Particle Counters and Mini Thermo-Anemometer respectively. The results obtained showed that the particulate matters (PM2.5 and PM10) at both study areas are below permissible limits required by Malaysian Ambient Air Quality Guidelines (MAAQS). However, the Air Quality Indexes of PM2.5 at both study areas shows that the AQI readings are categorized as unhealthy. The highest AQI reading was 159, which was recorded at residential area. In most cases, the results revealed that particulate matter produced by traffic vehicles has significant correlation with the increase of travelled particles. From the correlation analysis, both study areas have significant correlation of PM2.5 with medium vehicles while the educational area has correlation with all types of heavy, medium and small vehicles.

Set Up

The sampling sites, including roadsides and residential areas, were set up to collect ambient air and determine the volatile organic species it contained. For the roadside air, the average VOCs (volatile organic compounds) abundant at rush hour periods was two times that at non-rush hour periods. In the residential area, the VOC concentrationswere106 and 129 ppb during rush hour periods. The VOC concentration ratios of roadside and residential areas were in the range of 1.08–1.75 and the traffic emissions were related to the VOCs abundant in air. The highest VOC concentration was 168 ppb at midnight at residential sites and the VOC abundance could be two times that of roadside sites. This level of concentration could be attributed to the application of solvents and to human activity in a nearby motorcycle/vehicle maintenance plant, laundry rooms, etc. High abundant species were similar in both the roadside and residential air samples. These highly abundant species included toluene, acetone, acetonitrile, m,p-xylene and n-pentane, all of which can be emitted from traffic exhaust. Benzene, acrolein, formaldehyde, vinyl chloride and 1,3-butadiene were the main species with health impacts collected at both sites. In the micro-scale environment, the residential ambient air was affected by traffic flow from morning to night. In the midnight period, some local activities (a motorcycle/vehicle maintenance shop and laundry shops) affected the concentrations of certain VOCs (acetonitrile, toluene, hexane, 2-methylpentane, methyl cyclopentane and 3-methylpentane). The traffic and motor vehicles’ effects were determined, which could be useful for air quality management and strategy development in an urban area.

Urban areas are generally in the form of housing with narrow land. The purpose of this activities was to use narrow land for farming with verticulture techniques. The activity was held in Puri Zahara 1 Residence, Medan Tuntungan District. which is a residential area with narrow land. The method used was to provide training to housewife to be able to utilize the land with verticulture techniques. Housewives was briefed in order to be able to use the land using existing materials, especially verticulture techniques. The material used in verticulture techniques was paralon. The result of this dedication is that the community can utilize small land, especially in residential areas with verticulture techniques to plant flowers or vegetable crops, so that the house becomes greener and livelier. With this verticulture technique, more vegetable or fruit crops can be planted.  some plants planted include lettuce, water spinach, flowers

Ambient Air Quality

Though water and land pollution is very dangerous, air pollution has its own peculiarities, due to its transboundary dispersion of pollutants over the entire world. In any well planned urban set up, industrial pollution takes a back seat and vehicular emissions take precedence as the major cause of urban air pollution. Air pollution is one of the serious problems faced by the people globally, especially in urban areas of developing countries like India. All these in turn lead to an increase in the air pollution levels and have adverse effects on the health of people and plants. Western countries have conducted several studies in this area, but there are only a few studies in developing countries like India. A study on ambient air quality in Tiruchirappalli urban area and its possible effects selected plants and human health has been undertaken, which may be helpful to bring out possible control measures.

The present study is carried out in Gwalior to know the level of pollutants viz sulphur dioxide (SO2) and nitrogen dioxide (NO2). In this study, both NO2 and SO2 were collected during different seasons, and estimation was done using chemical methods. The methods used for the determination of SO2 and NO2 in the ambient air of Gwalior was (Modified West and Geake method) and (Modified Jacob and Hochheisier). The SO2 from the air stream was absorbed in a sodium tetramer curate solution. NO2 was collected by bubbling air through a sodium hydroxide solution to form a stable solution of sodium nitrate. Meteorological parameters like temperature, relative humidity were recorded by thermometers and hygrometry during the sampling. Rainfall data was taken from Indian Meteorological Department, New Delhi, for four sampling years. The statistical analysis was carried out between the level of pollutants SO2 and NO2 measured and meteorological parameters recorded during the sampling. This study observed that pollutants were very high in winter and summer compared to monsoon and post-monsoon periods due to the heavy transport movement and favourable meteorological conditions like temperature, humidity, rainfall, and wind speed and directions.

Ozone (O3) and nitrogen oxides (NOx) are closely related in the atmosphere. In ambient air, these pollutants always fluctuated depending on their emission sources and meteorological influences. The paper is aims to gain insight understanding of the monthly temporal variation of O3 and NOx concentrations to enable proper control strategies against these pollutants. One-year monitoring records from 1st January to 31st December 2009 of O3 and NOx at Pasir Gudang, were obtained from Department of Environmental Malaysia. Temporal analysis of O3 and NOx concentration fluctuation during annual and monthly were assessed using time series and scatter plots. The annual variations of O3 concentrations were negatively correlated with annual variation of NO and NO2 concentrations. Results suggest that NO concentration are higher than O3 and NO2 especially in May 2009. However, zero exceedences were recorded in the studied period for all pollutants against the Malaysia Ambient Air Quality Guidelines.
