# Modeling the impact of rain on population exposed to air pollution

## TL;DR

This paper presents a mathematical model to analyze how rain influences the removal of air pollutants and the resulting effects on human populations, highlighting rain's role in mitigating pollution-related health risks.

## Contribution

The study introduces a novel mathematical framework to quantify rain's impact on air pollution reduction and its implications for human health.

## Key findings

- Rain significantly reduces air pollutant concentrations.
- Pollution removal is more effective during rainy seasons.
- Impacts on human health are positively correlated with rain-induced pollution decrease.

## Abstract

Environmental pollution, comprising of air, water and soil have emerged as a serious problem in past two decades. The air pollution is caused by contamination of air due to various natural and anthropogenic activities. The growing air pollution has diverse adverse effects on human health and other living species. However, a significant reduction in the concentration of air pollutants has been observed during the rainy season. Recently, a number of studies have been performed to understand the mechanism of removal of air pollutants due to the rain. These studies have found that rain is helpful in removing many air pollutants from the environment. In this paper, we proposed a mathematical model to investigate the role of rain in removal of air pollutants and its subsequent impacts on human population.
