Estimation of inorganic particulate matter in atmospheres of villages in Bahrain, by dry fall

Inorganic particulate matter was sampled weekly during the period Feb–May 1992 in Bellad Al-Qadim [BQ], North Sehla [NS], Tubli [T], and Marq b n [MQ], during the period March–May 1992 in Ad Diraz [DZ], and Karzakk n [KZ] and from April–July 1992 in Al-Maʹamir [M] villages, Bahrain. The average mean conductivity of water soluble inorganic particulate matter was 140.55 μS cm−1; total suspended solid 0.0684 (g dm−3 total dissolved solid 172.68 (ppm), total hardness as MgCO3 48.88 (ppm); as CaCO3 51.51(ppm); Cl− 11.82 (ppm); Na+ 6.13 (ppm); K+ 1.7 (ppm); alkalinity 5.35 m M; and NO3− 2.69 (ppm). Each shows weekly variation in concentration. The aerosol data were influenced differently by some atmospheric parameters such as temperature, relative humidity, prevailing wind speed and direction.
