air pollution effects on respiratory system
Does air pollution affect the respiratory system?
are at greater risk of particle pollution-related health effects. Though the respiratory system has remarkable resilience to air pollution via its repeated mobilization of defense and repair mechanisms, constant exposure to elevated particle pollution will contribute to reduced respiratory function, even in apparently healthy people.
How does exposure to fine particles affect the respiratory system?
Studies have reported respiratory effects related to acute exposure to fine particles, including respiratory symptoms (especially in children and those diagnosed with asthma), reduction in pulmonary function, and increased airway inflammation and responsiveness.
How does air pollution affect children's health?
Among its findings: Higher air pollution levels increase short-term respiratory infections, which lead to more school absences. Children who play several outdoor sports and live in high ozone communities are more likely to develop asthma. Children living near busy roads are at increased risk for asthma.
How does air pollution affect life expectancy?
In general, air pollution decreases quality of life and life expectancy. It exacerbates acute and chronic respiratory symptoms in patients with chronic airway diseases, and increases the morbidity and risk of hospitalization associated with respiratory diseases. However, the mechanisms underlying these effects remain unclear.
Why Is Particle Pollution A Respiratory Health Concern?
Studies have linked particle pollution exposure to a variety of respiratory health effects, including: 1. Respiratory symptoms including cough, phlegm, and wheeze. 2. Acute, reversible decrement in pulmonary function. 3. Inflammation of the airways and lung (this is acute and neutrophilic). 4. Bronchial hyperreactivity. 5. Acute phase reaction. 6.
How Does Particle Pollution Affect The Respiratory System?
Particles deposited in the respiratory tract in sufficient amounts can induce inflammation, which has been demonstrated in both animal and controlled human exposure studies. The extent of pulmonary inflammation depends on particle dose and composition. Controlled human exposure studies have demonstrated increased markers for pulmonary inflammation
What Are The Respiratory Effects of Acute Exposure?
Studies have reported respiratory effects related to acute exposure to fine particles, including respiratory symptoms (especially in children and those diagnosed with asthma), reduction in pulmonary function, and increased airway inflammation and responsiveness. Additionally, epidemiologic studies have demonstrated that respiratory effects associat
What Are The Respiratory Effects of Chronic Exposure?
Epidemiologic studies conducted in the U.S. and abroad provide evidence of associations between long-term exposure to fine particles and both decrements in lung function growth in children and increased respiratory symptoms. The Children's Health Study (Gauderman et al., 2015) evaluated three separate cohorts of children who had longitudinal lung-f
How Does Particle Pollution Affect People with Asthma?
According to 2014 data, approximately 24 million Americans have asthma-- about 1 in 12 children (8.6 percent) and 1 in 14 adults (7.4 percent)(CDC, 2016). (For the most recent asthma data, go to CDC's asthma data page.) Asthma is a disease characterized by a variable degree of chronic airway inflammation associated with airway hyper-reactivity, rev
What Are The Health Disparities For Asthma?
Asthma effects are more problematic in young children, older adults, minorities, and those with lower SES A composite measure that is often comprised of a number of indicators, including economic status measured by income, social status measured by education, and work status measured by occupation. Each of these linked factors can influence a popul
How Does Particle Pollution Affect People with COPD?
COPD is a major cause of disability and is the third leading cause of death in the United States (Ford et al, 2013). COPD is a lung disease characterized primarily by chronic airway inflammation, mucous hypersecretion, and progressive airflow limitation. These structural changes result in symptoms of cough, dyspnea, and increased sputum production
What Is The Role of Fine Particles in Lung Cancer Incidence and Mortality?
Prior to discussing the relationship between particle exposure and lung cancer, it is important to note the evolving scientific evidence. In the context of EPA, the evaluation of scientific evidence for cancer and other health effects for particle pollution occurs in an Integrated Science Assessment (ISA) Reports that represent concise evaluations
