Air quality is a major area of importance in environmental engineering. Contaminants emitted along an air pathway from industry have been shown to have a major adverse public health effect worldwide. As a result, many government agencies are promulgating and enforcing strict air quality rules, and industrial facilities are employing environmental engineers to minimize emissions, impacts, and exposure to the public. Growing research and case studies have demonstrated a greater understanding of air quality engineering. Strategies and technologies exist to accomplish these goals. There are few “black and white” solutions, however. Engineering decisions to reduce air emissions and impacts draw upon a strong understanding of the technologies available, their effectiveness, cost, and capability of causing auxiliary production and environmental problems.


This course begins with a thorough explanation of the background and history of air quality engineering, followed by discussions of what we know about air emissions, different ways they are calculated, air pollution control (APC) technologies and strategies, factors involved in their ground-level concentrations, and potential health impacts and ways to regulate air emissions. The course is designed to help you understand the basics of air quality engineering and understand its particular language, terms, and approaches.


This online PDH course is intended for environmental engineers, design professionals, APC equipment manufacturers, machinists, inspectors, and construction workers who are interested in gaining a better understanding in air quality.


In this course, you need to review the course document titled “Air Quality Fundamentals” provided below. Once you complete your course review, you need to take a multiple-choice quiz consisting of twenty (20) questions to earn 3 PDH credits. The quiz will be based on the entire document.
