Mold Basics – Part 2

Molds are tiny, multicelled organisms made up of branching filaments called hyphae (singular: hypha). Some of the hyphae are embedded in the material on which the molds grow and are called vegetative hyphae. Many molds also have other hyphae, called aerial hyphae, which absorb oxygen from the air. Rhizoids, hairlike filaments resembling roots, grow from […]

Bulk Sampling For Mold

Bulk Sampling is another technique used for direct examination. A direct exam allows for the immediate determination of the presence of fungal spores as well as what types of fungi are present. Direct examinations should only be used to sample visible mold growth in a contaminated area since most surfaces collect a mixture of fungal […]

Surface Sampling For Mold

Surface sampling is the most common technique used to test surfaces for mold during a mold inspection.  It provides valuable information.  The species of mold, the relative degree of contamination, and the potential for airborne spore production may all be determined by tape sampling. This method can be performed using either standard, clear cellophane tape or a […]

Air Sampling For Mold

Taking air samples during a mold inspection is important for several reasons.  Mold spores are not visible to the naked eye, and the types of mold present can often be determined through laboratory analysis of the air samples.  Having samples analyzed can also help provide evidence of the scope and severity of a mold problem, as […]

Common Mold Tests

There are may forms of mold testing that can determine whether or not your home or office has mold, and the severity of issue if one exists.  The most common form of testing is Air Sampling, which basically traps spores in the air onto a sticky slide within a cassette that is mounted on top […]

Asthma Triggers Part 3 – Mold

Molds are microscopic fungi that live on plant and animal matter. Molds can be found almost anywhere when moisture is present. Molds create tiny spores to reproduce, just as plants produce seeds. Mold spores float through the indoor and outdoor air continually. When mold spores land on damp places indoors, they may begin growing. For people sensitive […]

Non-Culturable Air Sampling

Overview Non-culturable spore trap samplers draw measured volumes of air through the sampling device for a specified length of time. The collection surface is a coated glass slide. Particles in the air (spores, dust, etc.) impact onto the sticky surface and are “trapped” for later analysis. A general philosophy regarding the interpretation of biological air samples […]

Mold Growth & Sporulation in Buildings – Part 2

    Each stage of fungal growth (spore germination, vegetative growth, sporulation) has a specific set of conditions that is optimal. Important conditions in this set are nutrient types and concentrations, light, temperature, oxygen and water availability. Water availability (i.e., water activity) is one of the most important of these. Each fungus has optimal water activities […]

Types of Mold Inspections

Here’s a brief summary of the different types of mold inspections that can be performed to determine whether or not mold exists in a property. Air Sampling:  Air samples can be used to gather data about mold spores present in the interior of a property.  These samples are taken by using a pump that forces […]
