Concept
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
The Air Quality Index (AQI) is a standardized system used to measure and communicate the quality of air in a specific area, indicating how polluted the air currently is or how polluted it is forecast to become. It helps the public understand what local air quality means to their health, with higher values indicating greater levels of air pollution and a higher potential for adverse health effects.
Concept
Environmental monitoring is the systematic collection of data to observe and analyze the state of the environment, aiding in the management and protection of ecosystems. It involves the use of various tools and technologies to track changes in environmental parameters, helping in the assessment of pollution levels, biodiversity, and climate change impacts.
Concept
Aerosol science is the study of particles suspended in air or gas, which play crucial roles in atmospheric processes, climate change, and public health. Understanding the behavior, sources, and impacts of aerosols is essential for developing strategies to mitigate air pollution and its adverse effects.
Concept
Occupational health focuses on the physical, mental, and social well-being of workers in all occupations, aiming to prevent work-related injuries and diseases while promoting a safe and healthy work environment. It involves the anticipation, recognition, evaluation, and control of hazards arising in or from the workplace that could impair the health and well-being of workers.
Concept
Indoor Air Quality (IAQ) refers to the condition of the air inside buildings, influenced by pollutants, ventilation, and humidity, which can significantly impact health, comfort, and productivity. Effective management of IAQ involves identifying sources of pollution, ensuring adequate ventilation, and maintaining optimal humidity levels to minimize health risks and enhance well-being.
Concept
Particle size distribution (PSD) is a critical parameter in fields such as materials science, pharmaceuticals, and environmental science, as it influences the physical and chemical properties of a material, including its reactivity, stability, and appearance. Accurate measurement and analysis of PSD are essential for optimizing product performance and process efficiency, as well as for ensuring compliance with industry standards and regulations.
Concept
Filtration efficiency is a measure of a filter's ability to remove particles, contaminants, or impurities from a fluid or air stream, often expressed as a percentage of particles removed at a specific size. It is critical in applications ranging from air purification and water treatment to industrial processes and healthcare settings, where maintaining air and fluid quality is essential for safety and performance.
Concept
Atmospheric chemistry is the study of the chemical composition of the Earth's atmosphere and the reactions and interactions that occur among atmospheric components. It plays a crucial role in understanding climate change, air pollution, and the depletion of the ozone layer, influencing both environmental policy and public health.
Concept
Respiratory health refers to the optimal functioning and well-being of the respiratory system, which is essential for efficient gas exchange and overall health. Maintaining Respiratory health involves preventing and managing diseases, minimizing exposure to pollutants, and adopting healthy lifestyle practices such as not smoking and engaging in regular exercise.
Concept
ISO cleanroom standards are a set of internationally recognized guidelines that define the level of air cleanliness required for different manufacturing environments, particularly in industries like pharmaceuticals, biotechnology, and electronics. These standards help ensure product quality and safety by controlling the concentration of airborne particles and microorganisms within specific limits.
