Purpose of Mold Sampling During An Inspection
As part of determining whether an indoor environment is contaminated with excessive amounts of mold and requires remediation, Indoor Environmental Technologies (IET) routinely performs air and surface mold sampling or testing. While there are many types of sampling methods, IET uses two of them the most: Air sampling using a “spore trap” sampler. Considerable information can be ...

Air Sampling for Mold Inspections
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 well as aid in assessing human exposure to mold spores. After ...

A Moldy Summer and the Three H’s: Hot, Humid and Hurricanes
A Hot, Wet Summer During the hurricane season, hot humid air envelops most of North America. Beginning in the spring and lasting until the first frost of autumn, the air is typically well above 60% relative humidity, which is ideal for promoting the growth of mold. The official hurricane season runs from June to October, and even though they may not qualify as hurricanes, many storms at this time ...

Controlling Mold Growth in Buildings: Prevention and Control Strategies
In background quantities, molds can be found everywhere—in outdoor air, water, our homes, our clothing and even on our pets. They are present in such small numbers that they don’t trigger reactions in humans, except in ultra-sensitive individuals. But when molds find the right combination of moisture, food, and temperature, (and each species of mold needs a unique combination of ...

Mycotoxins: Oh My!
Mycotoxins, Toxic Chemicals Produced By Molds There has been a lot of talks recently about extremely toxic chemicals produced by molds, called mycotoxins. Testing/sampling and remediation companies, looking to make a fast buck, use the purple-est of prose in their advertising, hoping to separate you from your money. These advertisements have a grain (no pun intended) of truth in them but are ...

Mold Indoors – is it Living or Dead?
The more appropriate terms are: Is it Viable? or Non-Viable? Viable/non-viable are better descriptive terms since these molds act like plants in terms of growth. A mold spore is like a seed—if the right combination of food, heat, and moisture are present, the spore can grow and multiply—just like a seed that can be dormant for long periods and then begin to grow. What’s ...

Mold Testing – Interpreting Air Sample Results
Budget considerations often limit the number of air, surface or bulk samples that can be taken in an IAQ investigation. Once the laboratory has returned the test data, then someone has to decide how to interpret it. It’s not enough to simply compare indoor data to the data collected in the outdoor or control sample. Indoor air samples are subject to two kinds of error: False Positives and ...

Mold Odor Analysis Using a Purge and Trap Multimatrix Autosampler
Abstract Taste and odor are widely associated with drinking water quality. Musty odors, caused by compounds such as geosmin and 2-methylisoborneol (MIB), may lead consumers to believe their water is unsafe. These compounds are byproducts of the growth of blue-green algae and other microbes. Since consumers rely on taste and odor as primary indicators for water safety, water suppliers take steps ...

FIB micro/nano mould machining process for productivity improvement
FIB has been commonly used as a very powerful tool in the semiconductor industry. It is mainly used for mask repair, device correction, failure analysis, and IC error correction, etc. Currently, FIB is not being applied to the fabrication of the micro and nano-structured mould because of low productivity and sputtering rate has also been required to fabricate the 3D shape. In this paper, we ...

Hurricane Sandy: More Damage than the Obvious
We all know that Hurricanes leave a wide swath of destruction in their wake. Many communities along the shoreline are devastated. Many, many homes are completely destroyed; only rubble remains. Many of the houses, apartment buildings and stores that survive the structural damage wrought by the storm face delayed damage. High winds drive water through cracks and crevices around door jambs and ...

How to make sure that tools and molds build perfect parts: Guarantee that manufactured parts correspond to the production requirements
At the beginning of a manufacturing process, a mold, dye, or jig is engineered according to the theoretical CAD model. The aim of this tooling, made precisely from the nominal model, is to produce parts that correspond to the technical requirements. It turns out, however, that there are often differences between the theoretical model and the reality of an industrial environment. Different ...
