Particulate matter (PM) consists of tiny particles or droplets in the air that are harmful to human health and the environment, originating from sources like vehicle emissions, industrial processes, and natural events. These particles can penetrate deep into the lungs and even enter the bloodstream, leading to respiratory and cardiovascular issues, and are a major component of air pollution monitored by environmental agencies worldwide.
Concept
Aerosols are tiny particles or droplets suspended in the atmosphere, originating from both natural sources like volcanoes and human activities such as burning fossil fuels. They play a significant role in climate change and air quality, affecting the Earth's radiation balance and human health.
Air quality refers to the condition of the air within our surroundings, which affects human health and the environment. It is determined by the presence and concentration of pollutants and is influenced by natural and anthropogenic sources, weather conditions, and geographic factors.
Cardiovascular health refers to the optimal functioning of the heart and blood vessels, which is crucial for maintaining overall health and preventing diseases such as heart attacks and strokes. It is influenced by lifestyle factors like diet, exercise, and smoking, as well as genetic predispositions and medical conditions such as hypertension and diabetes.
Climate change refers to significant, long-term changes in the global climate, largely driven by human activities such as burning fossil fuels, deforestation, and industrial processes. It results in global warming, extreme weather events, sea level rise, and disruptions to ecosystems, affecting biodiversity and human societies worldwide.
Cloud condensation nuclei (CCN) are small particles in the atmosphere that provide the necessary surfaces for water vapor to condense into cloud droplets, playing a crucial role in cloud formation and precipitation processes. Their presence and concentration can significantly influence weather patterns and climate by affecting cloud properties and the Earth's radiative balance.
Solar radiation is the electromagnetic energy emitted by the sun, which reaches Earth and influences the planet's climate and weather systems. It is a critical driver of natural processes and human technologies, such as photosynthesis and solar power generation.
Emission sources are origins or processes that release pollutants or greenhouse gases into the atmosphere, contributing to environmental and health issues. Understanding and managing these sources is crucial for mitigating climate change and improving air quality.
Condensation nuclei are small particles in the atmosphere that provide surfaces for water vapor to condense into droplets, playing a crucial role in cloud formation and precipitation. These particles can originate from natural sources like dust and sea salt or human activities such as industrial emissions and vehicle exhausts.
