Minimize Mold Exposure in Your Home

From personal experience, I believe many people do not often understand the potential health effects of mold. Not only can mold cause allergic reactions in many individuals, but also the mytoxins produced by mold can cause immune system dysfunction and serious neurological problems.

There have been many recent cases of sick buildings with "black mold" as well as other types of mold that thrive on wet drywall and other materials. Severe mold contamination may require a mold remediation company to clean up the property and remove mold. In some cases, the property may be uninhabitable.

On a daily basis, however, there are some basic steps to avoid mold in your home:

1. Immediately address any leaks, no matter how small, in your roof, bathrooms, kitchens, or any other part of the home. Replace any drywall or wood that shows signs of mold.

2. If you have a central ventilation system, have the vents cleaned periodically (I have them cleaned about every 3 years) to remove any mold-spores as well as dust and particulate build-up.

3. In humid climates, use a dehumidifier, especially in basements.

4. Use vents in bathrooms or other areas where there is regular moisture.

5. Use bathroom squeegees after each shower to remove excess water from the shower stall to prevent mildew.

6. Make sure water drains away from the house at least several feet during rainstorms. A properly installed gutter system will help prevent standing water from accumulating around the foundation.

7. Opt for smooth floor surfaces, such as tile, rather than carpeting that can accumulate mold spores.

8. Use HEPA air filters in your home.

Green Living Getting a lot of Attention for Earth Day: NBC on toxic living test and NY Times on Green Living

Green living is in the news more than ever before tomorrow's upcoming Earth Day. Over the weekend, the New York Times Magazine featured a Green Issue . The issue focused on steps everyone can take to reduce their carbon footprints. Solar energy, walking, green building, and organic clothing were among the topics discussed.

Also Dateline NBC compared toxins in two families, one living green and one that does not. Both families took a body burdern blood test. Both families had over 40 chemicals out of 76 tested, but the levels were different for each family.

The non-green did not do well in terms of levels of chemicals for daily products: PFCs from cookware were very high in the non-green family (3X), parabens from body products (4X) in the women, phthalates from plastics very high in the boys of the non-green family, and triclosan (anti-bacterial) was much higher for the non-green family as a whole.

The green family did not do well in two catogories: bisphenol A (metal cans and baby items) as well as lead. It was higher in the parents, possibly from their childhoods.

Drugs/Pharmaceuticals In Drinking Water Video

An Associated Press investigation found that pharmaceutical drugs are widespread in drinking water suppliers. No one really knows what are the long-term health effects. This is yet another reason to install water filtration in your home. Reverse osmosis is one type of home system that is supposed to remove these drugs.

Eco-friendly and Healthy Things To Do for Spring

Spring is here and it is the perfect time to renew your home and garden with eco-friendly practices.

1. Buy a compost bin and begin to recycle household and garden waste for extra rich soil in your garden. Compost adds vital nutrients and microorganisms to the soil.


2. Use several inches of mulch on your garden instead of resorting to weed killers.

3. Buy organic seeds from Seeds of Change or other venues.

4. Spring Cleaning: unclutter your house to create a healthier indoor environment---minimizes dust and other allergens that collect on items and promotes easier cleaning.

5. Spring Cleaning: select natural and biodegradable cleaning products for your home. These are now readily available in health food stores, some grocery chains, and online stores.

6. Add solar lighting to your yard to save energy and provide an attractive addition to your organic yard.

7. Add recycling to your daily routine. Earth911 has a website that enables you to find a local recycling or reuse locations.

One Way to Improve Indoor Air Quality: Mechanized Air Cleaning Devices

Since most Americans spend the majority of their time indoors, good indoor air quality is increasingly more important for overall health. The air in your home or office can be a soup of chemicals, pollens, particles, and microbiological agents.

There are three major approaches to improving indoor air quality as enumerated by the EPA (United States Environmental Protection Agency).

The EPA states:

“Solutions to air quality problems in apartments, as in homes and offices, involve such actions as: eliminating or controlling the sources of pollution, increasing ventilation, and installing air cleaning devices.”

One Solution: Mechanized Air Cleaning Devices

• Air cleaning devices, come in many forms, but one common type is medium efficiency air filter installed in a special housing on duct systems. These usually have an accordion appearance and are 80-90% efficient.


• The other common type is the high efficiency (up to 99.9%) HEPA (High Efficiency Particulate Accumulator) systems installed on dust systems or as stand alone units. HEPA systems on ducts usually require additional fans to push the air through them. Stand alone and portable units also generate sufficient air flow to filter the air. These can filter down to 0.3 microns.


• There are also often adsorption filters that contain activated carbon to filter pollutants in the form of gases. The gas particles adhere to carbon as the air passes through the carbon filter.

AllerAir offers many high-quality, all-steel construction, portable units. Most units have HEPA and activated carbon. A UV lamp can even be added to sterilize bacteria, viruses, and mold present in the air.

The Controversy Over Bottled Water: One Solution--Home and Office Water Purification

Recently after San Francisco Mayor Gavin Newsom (2007) banned the purchase of bottled water by City funds, there has been greater discussion about the benefits and drawbacks of bottled water. Some argue that the transport and processing of bottled water as well as the disposal of bottles negatively impacts the environment. They also argue that tap water is as healthy as bottled water.

While municipalities across the country do remove a majority of water contaminants, it is also true that there are residual contaminants in the water. The disinfection process also adds chloramines and other byproducts. The United States Environmental Protection Agency (EPA) regulates allowable levels of contaminants in drinking water. A list of contaminants and their possible adverse health effects is available on the EPA website:

http://www.epa.gov/safewater/contaminants/index.html#dbps

The EPA categorizes possible water contaminants into: microorganisms, disinfectants, disinfection byproducts, inorganic chemicals, organic chemicals, and radionuclides. There can also be turbidity from soil runoff and other nonregulated contaminants. Not mentioned on this list are possible contaminants, such as copper or lead, after municipal processing from local water pipes.

In reviewing the water quality report for my local city, for instance, I found small and permissible amounts of lead, copper, barium, nitrate, atrazine (herbicide), simazine (herbicide), and chloramines, among others. Even if the low levels present are acceptable by EPA standards, it is a personal choice as to whether one would prefer to ingest even lower levels of contaminants and also have better tasting water.

One solution is to add a whole house/office or individual faucet water purification system to remove the residual contaminants. Seagull, for example, offers water purification systems with a “structured matrix technology” that remove trace amounts of chemicals and any microbiological contaminants found in tap water and creates water quality that is as good as or better than bottled water. In fact, the structured matrix is also “certified to meet the EPA standard for microbiological ‘purification’.”

There is also the added benefit of having purified water for pennies per glass instead of the higher cost for bottled water.

What are Green Buildings?

There are many definitions. Some define green buildings as indigenous architecture that utilizes local materials and design options as well as utilizes passive solar. Adobe Homesin New Mexico are often a good example of this concept.

Others define green buildings in more modern terms. Over the past 20 years, the term "green buildings" has evolved from many experiments and programs developed around the country, such as Austin's green building program.

The U.S Green Building Council has developed LEED standards for commercial buildings and has a pilot program to develop LEED standards for residential buildings. Buildings become LEED certified by including a specified green building standards for construction.




In general, many of the green building programs often include some of these general principles:

•Site Selection, Design and Preparation: Design sites to have the minimum impact upon wildlife, trees, and other natural features.
•Educate contractors on minimizing environmental impact on construction sites. Recycle remainder building materials and minimize waste as well.
•Design buildings to efficiently use natural light, building orientation to sun, and other site features.
•Select low-impact building materials whenever possible—renewable materials (ex. Bamboo) or recycled materials.
•Select building materials with low volatile organic compounds and off-gassing for healthy indoor air quality.
•Energy-efficient appliances and HVAC systems.
•Solar energy whenever possible.
•Xeriscaping or other native plants for landscaping to eliminate the use of pesticides, herbicides, and fertilizers. Minimize the use of water for landscaping. Use organic gardening practices.
•Select low-maintenance building materials whenever possible to minimize the future use of building materials and lower long-term costs.
•Promote less-toxic house cleaning practices to minimize indoor air pollutants and contaminants in water runoff.
