Malodor refers to an unpleasant or offensive smell that can arise from various sources, such as decaying organic matter, certain chemicals, or poor hygiene. It is often associated with odors that are strong and repulsive, making them easily recognizable and difficult to tolerate. Common examples of malodor include the smell of rotten food, sewage, or body odor. The perception of malodor can vary among individuals, influenced by factors like personal sensitivity and cultural background. In many cases, malodor can indicate the presence of harmful substances or unsanitary conditions, prompting the need for proper sanitation and odor control measures to maintain a healthy environment.
