Description: The term ‘miasmatic’ refers to something that is related to or similar to a miasma, which has historically been understood as a harmful emanation or vapor believed to cause diseases. In the environmental context, the concept of miasma relates to the idea that certain environments, especially those that are unhealthy or contaminated, can release harmful substances that affect the health of living beings. This term evokes images of foul air, stagnant waters, and living conditions that promote the proliferation of diseases. The notion of miasma was predominant in medicine until the 19th century, before more modern theories of disease transmission were developed. Despite its obsolescence in contemporary medicine, the term remains relevant in discussions about air quality and pollution, where it is recognized that certain environments can be detrimental to public health. In this sense, ‘miasmatic’ can describe not only air quality but also the influence of environmental factors on human health and overall well-being. Thus, the concept has adapted to new realities, maintaining its essence as a warning about the dangers that can arise from degraded or contaminated environments.
