What is a common source of odors in residential areas?

Food substances are indeed a common source of odors in residential areas due to their perishable nature. When food is left out, spoiled, or improperly stored, it can lead to the growth of bacteria and mold, which contribute to unpleasant smells. Foods such as rotting fruits, vegetables, meats, and dairy products release volatile organic compounds as they decompose, resulting in strong, often offensive odors that can permeate throughout a home.

In contrast, while new paint, cleaning products, and fresh flowers can produce distinct smells, these odors are generally transient and not typically as persistently problematic as those from food substances. New paint might emit strong fumes initially, but these tend to dissipate over time. Cleaning products also have a noticeable scent when used, but their odors are intended to be pleasant or neutralizing. Fresh flowers might introduce lovely fragrances but are unlikely to create the type of odor issues associated with decaying food. Thus, food substances stand out as a significant concern for residents seeking to manage and control odors in their living environments.
