Assessment of power plant emission and its health impact in Gaza

The aim of study was to investigate the concentrations of the ambient air pollutants (i.e PM2.5, CO, CO2) and to examine the health impacts on the residentials living surrounding the power plant in Gaza City-Palestine.The pollutants were monitored several distance surrounding the plant for a period of four months during both summer and winter seasons using a portable laser particle counter and gaseous monitor. A public health questionnaire was also distributed on the residents living around the power plant in order to assess the impact of air pollution on their health status.The results showed that the concentration of particulate matter exceeded the WHO standard where the highest level was 79 ?g/m3 and the lowest level was 49?g/m3. However the concentration of carbon monoxide was lower than the WHO standards where the highest level was 2.18 ppm and lowest level was 0.1 ppm. Moreover, the concentration of carbon dioxide oscillated from 254 ppm to 514 ppm. The health assessment results showed that 50% of the study sample suffered of breathing difficulties.This study concluded that the concentration of particulate matter and carbon dioxide were high, while the level of carbon monoxide was low, furthermore the level of public awareness was good. Meanwhile 40% of population sample visited the hospital because of a disease that infects the respiratory tract

Investigation of Air Pollution Impact on Kinta River Water Quality at a Tropical Region

Critical air quality levels lead to an unhealthy environment which disrupts physical activities and human health. Wet deposition of air pollutants might cause a high concentration of water pollution due to rain water washout of nitrate and particulate matter (PM). This study aimed to investigate the impacts of air pollutants deposition on river water quality in Malaysia. The methodology involved in the analysis of secondary data (January to December 2013) for air quality and river water quality using factor, correlation, and regression. Parameters of air quality were PM10, Nitrate (NO3), ozone (O3) and temperature while water quality data were turbidity, Nitrate and PM10 (Ca, As, Hg, Cd, Cr, Pb, Zn, Cl, Fe, K, Mg, Na). The results show that there were positive correlations between air quality indicators and Kinta river water quality parameters. Correlation matrix shows that in terms of turbidity, air and water data were having 96% similarities. Regarding Nitrate concentrations, air and water records had only 30% of correlation matrix, which can be due to other sources of Nitrate which was agriculture activities near Kinta River. The factor analysis results showed that PM was the main contributor to river water quality particles with 94%. © 2020 Published under licence by IOP Publishing Ltd

Temporal distribution of non-methane hydrocarbon (NMHC) in a developing equatorial island

Non-methane hydrocarbons (NMHC) play a vital role in the formation of ozone in urban environment, where vehicle emissions are dominant. Ozone is known for its negative impacts on human health and environment. This study examines the prevalence of NMHC using central fitting distribution for equatorial area of Penang Island, Malaysia. The results of the diurnal variations of the NMHC concentrations measured during the years 2005 and 2006 showed that the concentrations were varying over the 24-h period while peaking from 8:00 to 10:00 am. In 2006, the maximum concentration of NMHC at the island station was 0.30 ppm, and the minimum level was 0.15 ppm. In term of probability distribution, the NMHC concentrations surrounding the station were well represented by Weibull distribution in 2005 and lognormal distribution in 2006 with an accuracy of 99.6 and 99.4 %, respectively. Moreover, the predicted number of days exceeds the US standard for NMHC (0.24 ppm) were 107 days. The Pearson’s correlation analysis showed a significant correlation (average r > 0.85) between NMHC concentrations and the measured CO emissions which indicate that they have a common source which is vehicular emissions. The factor analysis results showed that the temperature and humidity were the main contributors to the variance of NMHC concentrations. This study suggests that a special attention should be taken into consideration because of the potential health threat posed to the human
