Final answer:
An environmental microbiologist would investigate air contamination causing illnesses by identifying chemical and biological pollutants in the environment and using bioremediation technologies.
Step-by-step explanation:
An environmental technician who specializes in the study of microorganisms, known as an environmental microbiologist, would be well-suited to investigate air contamination believed to cause illnesses. The investigation would likely involve identifying and quantifying chemical and biological pollutants in the air that could pose a risk to human health.
Environmental microbiologists employ bioremediation technologies to remove pollutants, using specially selected or genetically engineered microbes. They play a critical role in assessing both outdoor and indoor air quality, where pollutants can cause a range of health issues, including respiratory problems and other serious conditions. Particularly, those with pre-existing conditions such as heart and lung diseases, diabetics, older adults, and children may be more susceptible to air contaminants.
Given that the contamination can stem from different residential, commercial, and industrial sources, the environmental microbiologist would also investigate these potential origins of the air pollution. Overall, such experts contribute to the field of environmental toxicology, developing protective strategies to safeguard human health and the environment from the adverse effects of pollutants.
