Mold is a microorganism that is classified as fungi. It’s a living organism that doesn’t fall under either the plant or animal classification in accordance with scientific standards.
There are many different types of molds that can be found in the environment. Invisible to the naked eye, mold spores travel through the air and are commonly found in soil and on decaying matter. Outdoors, mold plays a big part in the natural degradation of plant matter. However, when mold travels indoors, it can be hazardous to your health.
Mold comes in a variety of colors including white, brown, orange, green and black. Mold often has a furry look or resembles a stringy slime, but certain molds can also have a powdery-look. Black mold is considered to be the most dangerous type of mold found in homes.
Mold can grow at an extremely fast pace. A mold colony can form in as little as 48 hours from the initial contact a mold spore makes with a surface.
Health Risks Caused by Mold
Mold exposure can lead to several health-related problems. With its natural ability to travel through the air, the inhalation of mold spores can create a variety of respiratory ailments. Common side effects include asthma, allergies, respiratory infections, sinus infections and skin rashes. In some cases, mold exposure can even be fatal.
