Aerosol generation refers to the process of creating tiny particles or droplets suspended in air, which can occur naturally or through human activities. Understanding aerosol generation is crucial for fields like environmental science, public health, and engineering, as it impacts air quality, climate change, and disease transmission.

Natural Processes

Human activities encompass the diverse range of actions and behaviors carried out by humans to sustain life, fulfill needs, and pursue interests. These activities impact the environment, society, and economy, shaping the world we live in through both positive and negative consequences.

Human Activities

Environmental science is an interdisciplinary field that integrates physical, biological, and information sciences to study the environment and find solutions to environmental problems. It aims to understand how human activities impact natural ecosystems and develop sustainable practices to protect and preserve the planet for future generations.

Environmental Science

Public health is a discipline focused on protecting and improving the health of populations through organized efforts and informed choices of society, organizations, communities, and individuals. It encompasses a wide range of activities, from disease prevention and health promotion to policy-making and research, aimed at ensuring conditions in which people can be healthy.

Public Health

Engineering is the application of scientific and mathematical principles to design, build, and analyze structures, machines, and systems, aiming to solve real-world problems efficiently and sustainably. It encompasses a wide range of specialized fields that address various aspects of technology and innovation, driving progress in industries and improving quality of life.

Engineering

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.

Air Quality

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.

Climate Change

Disease transmission refers to the mechanisms by which infectious agents are spread from one host to another, playing a critical role in the epidemiology and control of infectious diseases. Understanding the modes of transmission, such as direct contact, airborne, vector-borne, and fomite transmission, is essential for implementing effective prevention and control measures.
