Mold Growth on Imported Products

Mold growth on products is a major problem facing many manufacturers, vendor suppliers, warehouses, wholesalers, distributors, and retailers. Millions of dollars are lost every year to mold growth. The problem is that products of organic nature such as clothes, leather products, wooden products and many others are subject to damp conditions while in transit from overseas manufacturers.The conditions during transit can cycle between hot and cold during the day and night respectively. … [Read more...]

Water Activity Requirements For Mold Growth

Definition of Water Activity Water activity (aw) refers to "free" water available for microbial growth. For microbial growth to occur, moisture must be freely available. The water activity of a material determines which types of mold would grow on that material.Technically, the water activity is defined as the ratio of the vapour pressure exerted by the water in the material to the vapour pressure of pure water at the same temperature and pressure.Types of Mold based on Water … [Read more...]

What is Aspergillus fumigatus?

Aspergillus fumigatus is a thermotolerant/thermophilic fungus capable of growing over a wide temperature range (12°C–53°C). It has a worldwide distribution. Being thermotolerant, it is a significant component of compost microflora. Health effects associated with Aspergillus fumigatus The spores of Aspergillus fumigatus are very small. Having a diameter of 2–3.5 µm, they are easily inhaled deep into the lungs. It is estimated that people inhale at least several hundreds of spores of Aspergillus … [Read more...]

How to improve spore trap results

Spore trap data should be reliable if results are to be used in assessing indoor spore types and concentrations and ultimately to evaluate the validity of exposure potential or remedial success.  Spore trap results are primarily used in indoor mold investigations to:assess the airborne spore concentrations and the potential for human mold exposure justify remedial recommendations and implementation evaluate quality control and post-remedial assessments of mold remediation … [Read more...]

Understanding Spore Trap Results

When enumerating airborne fungal spores, most labs, for practical reasons, analyze a percentage of the sample trace (often 15-25%) instead of 100%. A few labs claim that they analyze 100% of the sample trace. Obviously analyzing 100% of the sample trace sounds better than analyzing say 25%. In fact, some people argue that analyzing less than 100% of the sample trace is incorrect, inaccurate and gives skewed results. However, it is important to note that the accuracy of spore traps is affected by … [Read more...]

Mould contamination in schools and health effects on children

Mould contamination is now recognized as a major factor in the indoor air quality of schools. Children are at high risk of health problems that result from mould exposure. Kids rarely stop to wash their hands. Obviously, they will be the victims of mould and other microbial contamination. Schools are responsible to provide special accommodations to children who are sensitive to indoor air pollutants. Parents and personnel should know the health effects of moulds on children’s health. Health C … [Read more...]

Airborne Fungal Spores

Fungal spores and especially mold spores are a normal component of the outdoor air. They are microscopic structures that function as "seeds" to allow fungi to reproduce. Apart from acting as "seeds" for reproduction, many fungal spores are adapted for dispersal and for survival, often for extended periods of time, in unfavorable conditions. Airborne Fungal Spores In the Outdoor Environment Spores are released into the environment from fungi growing as saprophytes or parasites. Saprophytes are … [Read more...]

Mold Spores In Air And Health Issues

Mold spores are tiny structures produced by molds for the purpose of reproduction, i.e., they are "seeds" but unlike the plant seeds mold spores do not contain a preformed empryo. Health Effects Associated With Mold SporesMold spores are common in household and workplace dust. Also, due to their light weight, mold spores are often floating in the air both outdoors and indoors. Inhaling mold spores may cause allergic reactions in sensitive individuals. Allergic responses include hay … [Read more...]

What Do Your Mold Lab Test Results Mean?

Interpreting lab test results for indoor mold is currently not standardized. Therefore, it would not be surprising if you give 10 different people same copy of lab test results for interpretation and you get 10 different opinions. However, if you tell the 10 people what you wanted to find out from those results and also give them visual assessment results and the history of the building, you are likely to get most of the people arriving at the same conclusion. In other words, lab test results … [Read more...]
