Which western materials are most likely to pose a threat to human health?
Western materials, especially petroleum and rubber, are among the most likely sources of pathogens that can cause infectious disease.
Here are some of the potential sources: Chemical, biological and toxic substances like pesticides, flame retardants, herbicides and fertilizers.
These chemicals are not regulated by the World Health Organization but are widely used in industrial processes.
In many cases, they are combined with toxic metals and chemicals that can result in toxicity to humans.
A toxic substance can include lead, cadmium, arsenic, mercury, mercury compounds, mercury vapors and other contaminants that can be released when exposed to a flame, gas or other ignition source.
Many of these chemicals have been found in petroleum and other plastics that are frequently used in home or commercial production.
Carbon monoxide, a gas that can damage the lungs, can also be released from these materials.
The risk of respiratory illnesses due to chemical exposure is high for people who are exposed to the air around these products.
For example, it is possible that these chemicals can cause serious problems for people with asthma.
Environmental contaminants can also cause problems for health, like lead, mercury and cadmias, which can be absorbed into the body through the skin or ingested by the body.
Pesticides and fungicides can also pose a risk to people.
Some of these toxins can be harmful to humans and other animals, and some can be poisonous to humans as well.
Chemicals that can make people sick can be found in a wide range of products, ranging from household cleaners to household cleaners used for industrial purposes.
They include: benzene, which is used to make paints, degreasers, lubricants and cosmetics; methylene chloride, used in paint, degreevers, lubricators and cosmetics, and the dioxin and DDT chemicals that are commonly found in paints and degreasing products.
Chemical pesticides, such as DDT and hexachlorocyclohexane (CCH), which are commonly used in chemical pesticides, and are known to be toxic to humans, can be toxic for people.
Toxic chemicals, including perfluorocarbons (PFCs), used in plastics, have also been found to cause cancer in animals.
Hexachlorophenol (HCP), which is found in household cleaners, degrees and rubber cleaners, is toxic to human and animal cells.
Methanol is a commonly used solvent in household cleaning and degres and is also known to cause liver damage in laboratory animals.
The use of these substances in home and commercial production poses a risk for people, and they are known carcinogens, such that exposure can result from repeated exposure.
Sulfuric acid is a common solvent in many household cleaners and degrees, which has been linked to lung cancer in laboratory rats.
Toxins that are naturally occurring in plants and animals, including organochlorines, pesticides, chemicals and mold can also affect human health.
Bacteria, viruses and fungi can also damage the human immune system and cause diseases like cancer.
Other sources of potential risks include: Electrical wiring, such a wiring that is used in electrical equipment and electrical transformers, and other products that are used for electrical or mechanical work.
Electrical machinery and components that are installed on roads and highways.
Metal or plastic materials that are exposed on vehicles or used in plumbing, plumbing fixtures, faucets, drains, air conditioners, refrigerators, ovens, dishwashers and washing machines.
Natural gas, which contains methane, a greenhouse gas, and hydrogen chloride, which are also known carcinogenic, can make its way into our bodies through inhalation and ingestion.
Coal ash, which collects in landfills and disposal sites and is toxic when it decomposes, can cause respiratory diseases in humans.
Diseases that are caused by bacteria, viruses, fungi and toxins include: Diarrhea, including diarrhea caused by Enterobacteriaceae (e.g. salmonella and salmonellosis) and Campylobacter (a common yeast infection) and gastric and other stomach disorders caused by Streptococcus mutans.
Diarrhoea caused by a range of organisms including Enterobacteria (e,g. E. coli) and Klebsiella pneumoniae.
Fluid retention caused by hydrogen chloride.
Risk factors for respiratory diseases include: High blood pressure (hypertension), high cholesterol, diabetes and obesity.
Heavy smoking and physical inactivity.
Low levels of vitamin B12.
Lack of exposure to ultraviolet radiation, such an exposure that is toxic in high concentrations.
Poor nutrition and water and electrolyte balance.
An imbalance of vitamin D and calcium.
High levels of cholesterol and triglycerides.
Low vitamin D levels.
