Introduction

Many epidemiologic studies had been conducted on the health consequences of air pollution. The effects have shown that exposure to air pollution is associated with a number of acute and persistent fitness consequences, from minor physiological problems to dying from respiration and cardiovascular diseases. a few outcomes emphasize that long-time period publicity to particulate remember can lessen the lifetime of a person. PM10 raises the risk of respiratory death in children, decreases lung function and exacerbates allergies, and causes various respiratory symptoms in children such as coughing and bronchitis. PM2. Five has a serious effect on fitness, increasing the danger of demise from respiratory and cardiovascular illnesses and lung cancer. Toxicological research has shown that fine particles are extra related to respiration and cardiovascular sicknesses than large debris. The assessment of biomarkers within the blood is one of the methods for estimating the effects of air pollution on human beings. any other new approach to gather exhaled breath condensates in estimating the outcomes of air pollution. Exhaled Breath Condensate (EBC) is a non-invasive, appropriate, and inexpensive technique used for medical research and analysis of respiration illnesses. the formation of EBC after condensing droplets launched by airflow from the airway lining fluid and being diluted by way of alveolar air and blended by risky molecules of the airway tract. it is also possible to detect some effects via gathering exhaled air condensate and dimension of biomarker adjustments. EBC identifies the fluid composition of the respiration tract and allows to perceive and to diagnose the diseases. The number one component of EBC consist of accumulated aerosols in the respiration tract, distilled vapours around aerosols, and evaporated gasoline dissolved in distilled water vapor inside the respiratory tract. Simple ions such hydrogen ions, hydrogen peroxide, proteins, cytokines, eicosanoids, and macromolecules, as well as mucin, phospholipid, and DNA, make up EBC, which is made up of molecules inside the breathing tract diluted with water vapours. Exhalation air is utilised in studies, such as determining blood glucose. In various disorders, investigations have shown that the attention of markers in EBC is better than usual. The detection of certain chemicals is contingent on the available era for analysis. The study of inhaled condensate biomarkers had progressed to a remarkable level. As a result, novel macromolecules have been discovered in exhaled air in various studies [1].

Air pollution is composed of a complex mixture of gaseous and particle components, all of which are harmful to human health. While the composition of air pollution varies substantially depending on the source, research from throughout the world consistently reveal that air pollution is a significant modifiable risk factor for increased morbidity and mortality. In addition, clinical studies have shown that particulate matter (PM) air pollution has a greater impact on health than gaseous pollutants. PM has a wide range of negative health consequences on humans, especially on the cardiovascular system [2].

Exposure to PM air pollution, both acute and chronic, is linked to an increased risk of death from cardiovascular disorders such as ischemic heart disease, heart failure, and ischemic/thrombotic stroke. Particulate matter has also been discovered as a substantial endocrine disruptor, contributing to the development of metabolic diseases such as obesity and diabetes mellitus, both of which are cardiovascular disease risk factors. While epidemiological evidence supporting the harmful effects of PM air pollution on human health is becoming more widely accepted, fresh research is giving insight on the mechanisms by which PM causes harm [3].

To avoid and limit the negative health effects of this pervasive environmental concern, a better knowledge of how PM exerts harmful effects on human health is essential. Air pollution is becoming a major public health issue, with mortality from it estimated to quadruple by 2050. We examine the epidemiological data for PM's cardiovascular effects and present current understanding of the molecular processes by which PM causes cardiovascular disease by exerting harmful effects on the cardiovascular system [4].

Epidemiological Studies Linking Pm Exposure to Morbidity and Mortality in Humans

Since the first part of the twentieth century, there has been a link between high levels of PM air pollution and negative health effects. Smog incidents in Meuse Valley, Belgium, Donora, Pennsylvania, and London, U acutely caused increased hospitalizations and deaths, particularly in the elderly and those with pre-existing cardiac and respiratory diseases. The reductions in PM levels have led to gradual reduction in PM-associated morbidity and mortality; however, recent epidemiologic studies still consistently show a link between PM exposure and cardiopulmonary mortality [5].
