Final answer:
Black mold is an Environmental Hazard or Latent defect that can cause health problems when growing in moist environments indoors, leading to allergic reactions, asthma attacks, and various irritations. VOCs and formaldehyde emission are also indoor pollutants resulting from building materials that can affect health.
Step-by-step explanation:
An Environmental Hazard or Latent defect, such as black mold, refers to potentially harmful substances that may not be immediately apparent within an environment. Black mold growing on walls, ceilings, and other surfaces can be a significant health risk. It thrives in moist conditions, often after water damage, such as that from storms, floods, or leaks. Mold exposure can lead to various health issues, including allergic reactions, asthma attacks, and irritation of the eyes, skin, and respiratory system. Additionally, certain volatile organic compounds (VOCs) and other indoor pollutants like formaldehyde can be released by building materials, which may have both short-term and long-term adverse health effects. Some molds found in nature, like water molds, can also be detrimental to plants and aquatic life.
