黑霉, also known as black mold, is a type of fungus that appears as dark green or black spots on damp surfaces. It thrives in environments with high humidity and poor ventilation, often found in areas like bathrooms, basements, and around leaky pipes. Exposure to 黑霉 can lead to health issues, particularly for individuals with respiratory problems or weakened immune systems. Symptoms may include coughing, sneezing, and skin irritation. Proper cleaning and moisture control are essential to prevent its growth and protect indoor air quality.
