Indoor and outdoor airborne particulate matter (PM10 and PM2.5) were sampled from homes with different heating facilities, located at Sakaka city, northern of Saudi Arabia during winter season. Elemental composition of PM10 and PM2.5 samples, including Al, Ba, Be, Ca, Cd, Co, Cr, Fe, Ga, K, Li, Mg, Mn, Na, Ni, Pb, Se, Te and Tl, were analyzed using inductively coupled plasma-mass spectroscopy (ICP-MS). Black carbon (BC) was also measured using EEL-type Smoke Stain Reflectometer. Results showed that the highest indoor concentration PM2.5 (541.67 µg m–3) and PM10 (1201.39 µg m–3) were found at homes using wood burning as heating facility. The most dominant metals were Na, Fe and Al in the investigated PM2.5 and PM10 samples. The highest concentrations of black carbon were found in homes using wood burning as heating facility. For similar homes in heating facilities, we can deduce that by increasing the number of smoking persons the value of BC increased.

Concentration Levels

Characteristics of airborne particulate matter (PM) as well as its levels in air samples collected from selected sites within cities of Dhahran, Khobar, and Dammam, in the Eastern Province of Saudi Arabia, are investigated. Concentration levels of the 10 microns’ PM (i.e., PM10) are determined using the gravimetric technique. Morphological and chemical characteristics of the PM collected from the sampling cities are studied using Field-Emission Scanning Electron Microscopy (FESEM), energy dispersive X-ray (EDX), and X-Ray Fluorescence (XRF). Moreover, levels and types of hazardous materials related to these samples are assessed using Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES). Results revealed that the average concentration levels of PM10 were approximately 177, 380, and 126 μg/m3 in Dhahran, Khobar, and Dammam, respectively. The structure of PM collected in Dhahran was mainly platy and rod-like shaped with a size between 2 and 6 μm, while PM collected in Khobar was mostly irregular in form, with a size range between 2 and 8 μm, and Dammam’s PM was rounded and between 1 and 3 μm in size. Both EDX and XRF results indicate relatively high weight % of C, O, Si, F, and Ca with lower weight % of Na, Mg, and K at the 3 cities. Finally, the study shows that Ba and Zn were the main trace metals associated with the collected PM in the 3 cities.

. Metabolic syndrome is a serious problem in Saudi Arabia. It has been attributed mainly to life style. Exposure to airborne particulate matter is a subject of concern in Jeddah. The present study aimed to find a possible association of metabolic syndrome prevalence with levels of particulate matter and their elemental constituents. The study was conducted in two districts of Jeddah, Al Nuzlah and Al Rehab. PM10 and PM2.5 were measured in each district as well as their elemental composition. Metabolic syndrome was defined by the presence of three components: hyperglycemia, hypertension and obesity. Al Nuzlah district showed higher prevalence of metabolic syndrome, together with higher levels of PM2.5, nickel and cadmium. It can be concluded that exposure to particulate matter may be considered as an additional risk factor for metabolic syndrome.

Air borne particulate matter PM10 and PM2.5 were collected by using Mini Vol portable Air Sampler from the world most densely populated city Dhaka and its suburban areas over a period of January through December in 2016. This study revealed a comparison of atmospheric particulate matter (PM) of a highly polluted urban area to its two neighboring areas that accommodate heavy oil based power plants. In all three sites the quantity of PM decreases in summer reaching its lowest level in the month of July, however, it increases significantly in winter season. Despite the presence of the fuel based power plants the average concentrations of PM10 and PM2.5 at the city Dhaka surpasses its two neighbors Manikganj and Nawabganj. Interestingly, PM2.5/PM10 ratio is higher at the suburban areas than urban area. The study shows that for all the sites PM2.5 is approximately twice than that of WHO and USEPA. However, the values of PM2.5 is almost similar for Nawabganj and Manikganj but much higher for the Dhaka city especially during dry season . The Mass concentration of Black Carbon (BC) was also determined from the PM samples from Manikganj and Nawabganj. Journal of Bangladesh Academy of Sciences, Vol. 43, No. 1, 59-66, 2019
