    Opis:
    This study was conducted to measure the concentrations of four trihalomethane compounds (THMs) in raw, treated, and drinking water of seven water purification plants and the residential neighborhoods nearby in Baghdad. About 350 samples gathered between January and October 2017 and analyzed by the gas chromatography method. Results showed that THM annual levels in tap water ranged between 12 and 97.3 µg·l–1 in winter and summer consecutively, with a mean concentration of 60 µg·l–1, these concentrations did not exceed the level recommended by the WHO and the Iraqi standards. Statistical modeling by SPSS software for the formation of THM (the dependent factor) in the water supply network was undertaken using the measured water quality parameters (as independent factors) and utilizing multiple regression analysis. The model obtained has a high correlation (r = 0.842) and approved that the most affecting parameters on THM formation are total organic carbon, temperature, turbidity, total solids, and chlorine dose. The model that was derived may be used for the purposes of choosing appropriate THM-reduction procedures and the use of chlorine for improving the method of disinfection.

    Opis:
    Seasonal variability is the complex non-linear response of the physical climate system. There are two types of natural variability: those external and internal to the climate system. In any given season, natural variability may cause the climate to be different than its long-term average. This study examines with the seasonal variation of the maximum temperatures during the summer season. In addition, the maximum temperatures in May become close to the characteristics of the summer season. The monthly data for maximum temperature of May, June and July were used from Iraqi Meteorological Organization and Seismology (IMOS) for 47 years from 1970 to 2017 for Baghdad city. This period was long enough to estimate the range of approaching maximum temperature (Tmax) May to summer. Results revealed a significant Tmax for Baghdad during the second period (1992–2017) and ?shown similar behavior of Tmax in May to June and July; on the contrary that first period (1970–1991). In second period, two phases have been found out, positive phase and negative phase. The positive phase were happened in 1995, 1999, and 2006, and the negative phase was four cases (1992, 2004, 2013, and 2016), while a few cases recorded in first period. The amplitudes of monthly variability had same distance of leaner correlation especially in 1999 and 2013 that represent coherent wave with summer seasons. The variance difference for Tmax between May and June approximately was 2°C for second study’s period, while exceed this range in first period. This variance change to 7.5°C when found difference between July and May.

    Opis:
    This investigation aim to evaluate the effect of heat wave on health of human, so to achieve this 40 blood samples for person exposed to heat wave were drawn most patients were attend to specialists in hospital laboratories (Medical City, Ibn al-Baladi, Sheikh Zayed, Kadhimiya Educational). The patients aged 10–60 years, male (20) and female (20). CBC analyzes was performed. The result of the presents study recorded a highly signifi cant difference in total (mean and percent) as compared with the normal value of the CBC analyze the result for total (mean and percent) for male the factors CRP, ESR, WBC, PCV, PL (15.5, 43, 11.35, 28.5, 215) respectively (100%, 100%, 100%, 100%, 100%) and the result for total (mean and percent) for female the factors CRP, ESR, WBC, PCV, PL (15, 43.5, 11.35, 31, 220.5) respectively (100%, 100%, 100%, 100%, 100%). According to the result we can conclude that there was a highly significant deferent in mean value for patient compared with the normal value which is the mean cause of hard attack which lead to death. The study is the first of its kind in the Department of Atmospheric Sciences in Iraq.

    Opis:
    Tropospheric nitrogen dioxide (NO2) is a trace gas with important impact on atmospheric chemistry, human health and a key pollutant in particular cities, measured from space since the mid-1990s by the GOME, SCIAMACHY, OMI, and GOME-2 instruments. This study present ten years (monthly and yearly averaged) dataset from Ozone Monitoring Instrument (OMI) used to investigate tropospheric NO2 characteristics and variations over Iraq during 2005–2014. Annual NO2 shows an elevation from the northern to the southern and highest values was at central parts of Iraq. Monthly distributions revels higher values NO2 in winter and summer than spring and autumn seasons, and rising NO2 throughout study period over industrial and crowded urban zones. The trend analysis over Baghdad shows a linear growth rate 9.8% per year with an annual average (5.6·1015 molecules per 1 cm2). The air mass trajectory analysis as hotspot regions shows seasonal fluctuations between winter and summer seasons depend on weather conditions and topography. The increased NO2 values in winter are due to anthropogenic emissions and subsequent plumes from Europe. In addition, in summer because of hot weather and large paddy fields emissions. The lowest NO2 value was at monsoon period mostly linked to the rains. The OMI data and satellite information are able to observe the troposphere NO2 elevation at different regions.

    Opis:
    Based on daily minimum and maximum air temperature observations for three years: 2008, 2013 and 2019, measured by automatic weather stations located at two sites of Baghdad city were used to compute nocturnal and daytime urban heat island (UHI). First station fixed in campus of the Mustansiriyah University is considered as urban area, and another station followed to Iraqi meteorological organization installed at the International Baghdad Airport was chosen as the rural site. Daily, seasonal and annual averages of nocturnal and daytime UHIs were presented to study the variability and trends. The results show the evolution of a nocturnal UHI, whose high mean values were recorded in four seasons with largest value found in summer of 2019. Annual trend in nocturnal UHI intensities was found to be larger than that of daytime. Thus, this study propose that maintenance and increase urban parks and planting shading tall trees to mitigate UHI intensity in Baghdad city.

    Opis:
    The objective of this study was to estimate the height of roughness element (ZH) and zero-displacement length (Zd) for Baghdad city using remote sensing and GIS techniques and resources such as DEM, DSM, and shapefile. The difference between DEM and DSM produced digital height model which represents the height of the roughness element for the region, which was used to determine the zero-displacement height. The results showed that the variations in Zd values depend strongly on ZH. Rusafa had the highest Zd (15.8 m) while Dora had the lowest values (4.7 m). Thus, Baghdad city has medium density classification according to the results of Zd and ZH values.
