Concentration of air pollutants CO, NO2, SO2, O3, PM10, PM2.5 in four Iraqi cities (Al-Najaf, Al-Muthanna, Maysan, Kirkuk) and PM2.5 in Baghdad city were monitored and analysed for the period September 1, 2019 to August 31, 2020. The results showed that the daily mean concentration of CO, NO2 for the four cities are well below the WHO air quality standard. In general, PM2.5 and PM10 concentrations are the factors that govern the air quality index in Iraqi cities under consideration. It is clear that, for all the cities under consideration, the daily AQI is mostly “Moderate” and to a less extent “Unhealthy for sensitive groups”. However, there are 53 days for Al-Muthanna (mainly due to PM10) and 58 days for Baghdad (due to PM2.5 alone) in which the AQI is “Unhealthy”. Moreover, there are another 53 days for Al-Muthanna in which the AQI is “Hazardus”. So, the air quality in Al-Muthanna and Baghdad can be considered lower than that in other cities. Indeed, this is attributed to dust storms in Al-Muthanna and high population of Baghdad city and consequently higher air pollutants emissions due to their industrial, transportation and electric generation activities. AirQ+ software was used to assess public health consequences of long term exposure to PM2.5 in terms of relative risk (RR). RR of acute lower respiratory disease, chronic obstructive pulmonary, mortality by lung cancer, ischemic heart disease, mortality by stroke for the five cities were assessed. RR of mortality by lung cancer due to exposure to PM2.5 in Baghdad is the highest among the cities under consideration. RRLC = 1.25 (95% CI = 1.14 – 1.4).

Background: Valproic acid (VA) serve as the antimigraine, anti-mental disturbances agent and antiepileptic medicine. After using VA, metabolic rearrangements seen in patients that include alteration in lipoproteins levels; however, this topic is still under discussion and disputable. Aim: To discuss the effects of VA after using for long duration on total levels of cholesterol in adult. Methods: About Eighty candidates participated and they were divided into two groups namely, case group (40 candidates) and control groups40 candidates). All the candidates were asked for collection of venous blood sample in order to determine total cholesterol serum level among them via aid of enzymatic cholesterol oxidase phenol 4-aminoantipyrine peroxidase. By the aid of the logistic regression analysis, the relationship of the long-term VA treatment and the level of total cholesterol was obtained. With respect to our analysis, there is a co relation between total levels of cholesterol and long term usage of VA (P=0.003). Results: There were no noteworthy link for age, sex, body BMI, height medication usage, smoking, diabetes mellitus and VA dosage , except combination of anti-epileptic drugs Conclusion: In a net shell, by using VA for long duration, the total level of cholesterol in adults reduces.
