Critical assessment of air pollution by ANOVA test and human health effects

Purposes of this study evaluate air quality by analysis of heavy metals (Ni, Cu and Pb) using ANOVA two-way test (space and time) within Baghdad city. Samples were collected from 3 stations in Baghdad city for 2 years (2009 & 2010). Concentrations (lead) were mostly exceeding the specific proposed national lead = 2 μg m−3, nickel was exceeded for the specific (1) mcg m−3. That of the causes of increased concentrations of heavy metals in the air is the occurrence of dust storms which carry dust storms amounts of dust containing heavy metals from the surface of land passing through, causing high concentrations of total suspended particles and that was mostly exceeding the specific national proposal and thus increasing the concentrations of heavy metals. Which indicates the possibility that the dust raised by wind erosion, which led to high concentrations of total suspended particles are the soils coming from the industrial areas is most likely because it is loaded at rates greater than the concentrations of heavy metals originating in industry. In sum, more than 50% of the concentrations of as exceeding the specified or exceeding the rates for the public.

► We evaluate air pollution in Baghdad city.
► We examine heavy metals (Ni, Cu & Pb) and we found that, it is one of the reasons of air pollution in Baghdad city.
► We used ANOVA two-ways test for this study with respect for space and time.
► All the cases where F2 < F < F1 the variance has consistent values and for any other condition the test fails.
