Geographical analysis of the variation in nickel concentration in atmospheric precipitation in Anbar Governorate

Abstract

      The research aims to know the variation in nickel concentrations in atmospheric precipitation in Anbar Governorate and what are the factors affecting this. An analysis of the variation of nickel concentrations in air precipitation in Anbar Governorate between one location and another in the years 2021-2022 was studied. This is done by collecting samples of solid precipitation in small containers for solid precipitation, which were distributed in (7) places of the monitoring sites. The measurement continued for 12 months, starting from September 2021 to August 2022. Samples are removed monthly from the monitoring sites, and dust samples are analyzed and concentrations are measured. Nickel adhered to dust particles in environmental laboratories. The research found that there was a temporal and spatial variation of the nickel element in air precipitation in Anbar Governorate, and the

concentrations of the nickel element fell within the environmental limits, that is, they did not exceed the permissible environmental limits, which were estimated at (1) mg/kg. The research concluded that the highest recorded months for concentrations were during the month of July. The lowest concentrations were in the month of January, and the highest recorded sites for nickel were in the Fallujah site during the month of July, with a value of (0.78) mg/kg, and the lowest sites were in the Anah site during the month of January, with a value of (0.01) mg/kg.
