Background and Purpose: One of the fundamental problems of air pollution is that it often affects large areas of various land uses, such as cities and agricultural products hundreds of kilometers away from the source of pollutants, or results in cumulative effects with other industries. This research aims to quantify the concentration of pollutants in residential areas around industrial areas.Materials and Methods: In this study, the AERMOD software was used for modeling air pollutants. This software uses meteorological data, digital elevation models, and information about pollutant sources. It assesses and quantifies air pollution levels related to PM10, SOX, NOx, and CO pollutants in a specific location.Results: The results of this study indicate that in these 28 population points surrounding the targeted industrial land use, pollutant concentrations in both scenarios with and without background concentrations did not exceed the standard limits for any pollutant. The most significant pollutant in this research was NOx, which showed the slightest difference from the permissible pollution limit. Furthermore, due to the closer proximity of pollutants to environmental standards in this region, increased loading of industrial land uses can lead to various health, economic, and social problems.Conclusion: The findings of this research demonstrate that to assess and quantify pollutant concentrations in the areas surrounding industrial pollutant points, it is advisable to consider background pollution in addition to modeling point sources for greater accuracy in the direction of sustainable development in such areas.

Background and purpose: Industrial development, on one hand, creates harmful chemical products and industrial waste, including heavy metals. On the other hand, it increases energy consumption and leads to the release of atmospheric pollutants, causing environmental pollution. Bandar Abbas, compared to other areas of Hormozgan province, has a high concentration of industries. Therefore, it is necessary to study the pollution caused by these industries in the region's environment. The general purpose of this study is to investigate the amount of heavy metals associated with industrial activity.Materials and Methods: Ambient air sampling was conducted at seven locations in the region during winter and spring (2020). The sampling and preparation methods were based on EPA and NIOSH Standards. Sampling was performed using a High-Volume pump with a flow rate of 1.7 cubic meters per minute for a duration of 24 hours. The sampling device was installed at a height of 3 meters above the ground. The heavy metals in the collected samples were measured using the Varian Z220 atomic absorption spectrometer with the furnace technique. Circular fiberglass filters with a diameter of 47 mm were used for environmental sampling.Results: Based on the analysis of air particles, the concentration of heavy metals showed a decreasing trend as follows: V < Cd < Fe < Pb. The average concentrations of these elements were 0.0006, 0.0060, 0.0061, and 0.339 micrograms per cubic meter, respectively. With the exception of lead, the average concentration of these metals exceeded the limit value.Conclusion: The amount of suspended particles at all sampling locations exceeded the environmental standards. Additionally, except for vanadium, the average concentration of metals in the samples from residential areas was below the limit value.
