Asbestos describes any of a group of minerals that can be fibrous, many of which are metamorphic and are hydrous magnesium silicates. These minerals, together with their occurrences, uses, and associated hazards, have been discussed in detail by Guthrie and Mossman (1993).
The name is derived for its historical use in lamp wicks; the resistance of asbestos to fire has long been exploited for a variety of purposes. Asbestos was used in fabrics such as Egyptian burial cloths and Charlemagne’s tablecloth (which according to legend, he threw in a fire to clean). Asbestos occurs naturally in many forms (see below); it is mined from metamorphic rocks.
When asbestos is used for its resistance to fire or heat, the fibers are often mixed with cement or woven into fabric or mats. Asbestos is used in brake shoes and gaskets for its heat resistance, and in the past was used on electric oven and hotplate wiring for its electrical insulation at elevated temperature, and in buildings for its flame-retardant and insulating properties, tensile strength, flexibility, and resistance to chemicals. The inhalation of some kinds of asbestos fibers, however, can cause various serious illnesses, including cancer. Many uses of asbestos are banned in many countries.
Types of asbestos and associated fibres
Chrysotile, CAS No. 12001-29-5, is obtained from serpentine rocks. Chrysotile is the type most often used industrially in the United States. There is evidence that this type of asbestos is harmful, although not perhaps as harmful as other forms (refer to UK Health & Safety Commission report Asbestos: Effects on health of exposure to asbestos, 1985). One formula given for Chrysotile is Mg3(Si2O5)(OH)4.
Amosite, CAS No. 12172-73-5, is a trade name for the amphibole known as Grunerite, from Africa, named as an acronym from Asbestos Mines of South Africa. One formula given for Amosite is Fe7Si8O22(OH)2.
Riebeckite, CAS No. 12001-28-4, also known under the variety name of Crocidolite, is an amphibole from Africa and Australia. It is the fibrous form of the amphibole riebeckite. Blue asbestos is commonly thought of as the most dangerous type of asbestos (see above and below). One formula given for Crocidolite is Na2Fe2+3Fe3+2Si8O22(OH)2.
Diseases caused by asbestos
As early as 1898 the Chief Inspector of Factories of the United Kingdom reported to Parliament in his Annual Report about the “evil effects of asbestos dust”. He reported the “sharp, glass like nature of the particles” when allowed to remain in the air in any quantity, “have been found to be injurious, as might have been expected” (Report of the Select Committee 1994). In 1906 a British Parliamentary Commission confirmed the first cases of asbestos deaths in factories in Britain and recommended better ventilation and other safety measures. In 1918 a US insurance company produced a study showing premature deaths in the asbestos industry in the United States. In 1926 the Massachusetts Industrial Accidents Board processed the first successful compensation claim by a sick asbestos worker. Many American injuries from asbestos exposure came from shipbuilders working during World War II.
The problem with asbestos arises when the fibers become airborne and are inhaled. Because of the size of the fibers, the lungs cannot expel them. [Casarrett & Doull’s Toxicology (2001), pp 520-522]
Diseases caused by asbestos include:
Asbestosis – A lung disease first found in naval shipyard workers, asbestosis is a scarring of the lung tissue from an acid produced by the body’s attempt to dissolve the fibers.  The scarring may eventually become so severe that the lungs can no longer function. The latency period (the time it takes for the disease to develop) is often 10-20 years.
Mesothelioma – A cancer of the mesothelial lining of the lungs and the chest cavity, the peritoneum (abdominal cavity) or the pericardium (a sac surrounding the heart). It is believed that mesothelioma is caused by generation of reactive oxygen species (ROS) by the asbestos fibers. There is also some evidence to suggest that simian virus 40 (SV40) works together with asbestos in the development of malignant mesothelioma. Asbestos exposure is linked to at least 50% of patients developing malignant mesothelioma. Malignant mesothelioma has a peak incidence 35-45 years after asbestos exposure. Median survival for patients with malignant mesothelioma is 11 months. Asbestos has a synergistic effect with tobacco smoking in the causation of pleural mesothelioma.
Cancer – Cancer of the larynx has been linked to asbestos. Some studies suggest that asbestos exposure is linked to a slightly increased risk of stomach, pharyngeal, and colorectal cancer.

All buildings constructed prior to 1978 has the potential to contain lead-based paint. Colorado has among the highest lead poisoning rates in the nation with over 55,000 children identified between 1997 – 2000.
If you suspect your building contains lead-based paint, have the area inspected by a licensed building inspector – especially if there are young children or pregnant women present.
Lead exposure can cause a variety of health complications. The major pathways of lead into the body are ingestion & inhalation. Lead is especially toxic for children under the age of six and pregnant women, due to a higher lead absorption rate. Lead dust is especially dangerous for children, who can expose themselves to high amounts of lead through normal hand-to-mouth activities.
An estimated 1.7 million children have blood-lead levels
above safe limits set forth by the EPA.
The following are common health effects associated with exposure to lead:
- Learning Disabilities
- Impaired Growth
- Hearing Loss
- IQ Decline
- Stomach Aches
- Mental Retardation
Where is Lead Found?
Lead is primarily found in the exterior and interior paint of the building. Lead was added to paint for three main reasons: Color Enhancement, Increased Durability & as a Drying Agent. Lead-based paint is typically found in window systems, bathrooms, door jambs, soffits, chair rails and doors.
Lead in Water – Paint is not the only place you’ll find lead. Lead can also be found in drinking water, primarily through leaded solder, brass fittings/fixtures and primary service lines. If the building was constructed before 1978 and the original water piping is still present, it is recommended to have your water supply tested for concentrations of lead.
Lead in Soil – The soil surrounding a building can also contain lead. Leaded gasoline (deposited prior to phase-down in use), factory emissions, weathering and chipping of lead-based paint on the exterior of the building, and dust/dirt carried over from a construction site can all contribute to lead concentrations in the soil. This can become a health issue if there are children playing around the building, or you plan on performing landscaping.
Our Lead Services
Lead Risk Assessment – A licensed risk assessor will conduct a thorough inspection of the property to determine any lead hazards. Appropriate sampling may include dust wipes, soil sampling and water sampling.
Abatement Clearance Inspection – A licensed inspector will visually inspect and collect dust wipe samples within the area where abatement occurred.
Project Management/Air Monitoring – Generally performed during lead abatement activities or along the perimeter of the work area – used to determine exposure levels of lead in air.
On-Site Lead Risk Assessments – We obtains a combination of paint chip (deteriorated painted surfaces only), dust wipes, and soil samples to determine the existence, nature, severity, and location of lead hazards interrelated with the residence or structure. These samples are submitted to an accredited laboratory for analysis and characterization service using A.A.S. to determine lead concentrations.
Lead-based Paint Management and Remediation Consulting – Rocky Mountain Abatement lead-based paint consultants are also certified as project designers and in project site surveillance. Rocky Mountain Abatement can provide comprehensive services including Lead abatement Plans which assist in prioritizing the lead based paint to be abated, estimating the cost of abatement (including material replacement) and bid documents for contractor selection, establishing a project schedule, and recommending practical alternative solutions.
During the abatement phase, experienced site technicians and consultants can monitor abatement activities including personnel monitoring, ensure compliance with federal, state and local regulations, as well as the requirements of project specifications. Waste disposal consultation is offered to advise clients of alternative disposal methods and measures that may reduce the volume of lead that must be disposed of as hazardous waste.
After completion of a remediation project, consulting staff can prepare a comprehensive record of the project, including notifications to regulatory agencies, waste disposal manifests, medical monitoring and training records of contractor’s employees, records of air and wipe sample analysis, status of any remaining lead and recommendations to prevent future contamination.
Mold is everywhere. And, it’s been around forever. So, why is it such a problem to us now? Indoor air quality problems abound because of it.
“Sick Building Syndrome” is the term used to describe metabolic gases emitted from molds and fungi. These, in turn, create breathing problems along with other respiratory infections. These molds and fungi are plentiful and can grow well inside of our buildings. In fact, there are over 10,000 species of molds alone!
Any place that is wet or damp from seepage or flooding can host them. In buildings, the spores spread easily and quickly because of natural built-in conduits for their movement—like corridors, ventilation systems and other convenient connectors.
These “volatile organic compounds” (VOC’s) contribute to the “Sick Building Syndrome” which certainly can he a health hazard to its occupants. The presence of certain molds and fungi can actually render a facility uninhabitable. If left uncontrolled, mold and fungi can also cause deterioration of wood, insulation and other building materials. It is imperative that knowledgeable and experienced professionals be consulted to curb this hazardous threat through remediation and removal.
