Emissions of volatile organic compounds (VOCs) from certain solid or liquid materials have recently become a concern for states and environmental protection organizations. They are commonly found in a wide range of household products such as detergents, disinfectants, and even paints, all of which contain organic solvents, and gases emitted into the atmosphere. It can lead to harmful health effects, some of which may pose a risk to human health in the short and long term. In addition, polluted air spreads over long distances in a way that cannot be practically avoided or controlled, causing damage to the surrounding environment and living organisms. Air pollution has led to global warming, resulting in higher temperatures and climate change. This article used Stephen Maxwell's equation model with Polymath software to determine the molar flows of a mixture of gases polluting the surrounding environment and divided into two compounds A and B from point 1 to point 2. This process is summarized first by analyzing the binary diffusion of acetone (A) only through Air (C) and then separately studying the diffusion of methanol (B) only through air (C) to find a first approximation of the solution. This concept has also been used to calculate the molar flow and concentration of substances A, B, and C at different distances. Calculations were performed by knowing the diffusion coefficient of the previously mentioned compounds, which depends mainly on the temperature surrounding this gaseous mixture....................
