Variation analysis of cadmium concentrations in air precipitation in Anbar Governorate

Abstract

    Air pollution is one of the environmental problems and real disasters facing life on the planet, due to the terrible progress that man has reached at the expense of the environment, especially after the development of human activity, urban and industrial expansion at the expense of green agricultural lands on the one hand, and the spread of desertification and drought and its impact  Indirectly negative in heavy elements including (cadmium) in the solid air precipitation in Al-Anbar Governorate, especially since the location of Al-Anbar Governorate, which is located in the western part of Iraq, which is one of the largest provinces of Iraq in area.

   An analysis of variance was studied for the concentrations of cadmium in the solid atmospheric precipitation between one location and another in Anbar Governorate for the year 2021-2022.  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, where the measurement continued for a full year, starting from September 2021 to July 2022, samples are collected monthly from the monitoring sites, dust samples were analyzed and heavy elements were measured  Attached to dust particles in environmental laboratories.

   The research concluded that there is a temporal and spatial variation of the cadmium element in Anbar Governorate, and the research also concluded that the concentration values ​​exceeded the limits and environmental standards.  The month of September with a value of (0.085), and the lowest site in Anah during the month of January with a value of (0.002), the highest annual average of cadmium concentrations in the Ramadi site was (0.060), while the lowest annual average was in the Ana site (0.021).
