Are Dioxins and furans the same?
Are Dioxins and furans the same?
All dioxins have the same basic chemical “skeleton,” and they all have chlorine atoms as part of their make-up. Furans are similar, but have a different “skeleton”. These substances vary widely in toxicity. The one considered most toxic is referred to as 2,3,7,8-tetrachlorodibenzo-p-dioxin, or simply TCDD .
What is the effect of DDT dioxins and furans on human health?
People who have been unintentionally exposed to large amounts of these chemicals have developed a skin condition called chloracne, liver problems, and elevated blood lipids (fats). Laboratory animal studies have shown various effects, including cancer and reproductive problems.
What are furans dioxins?
Dioxins, furans, and dioxin-like polychlorinated biphenyls (PCBs) are the abbreviated names for a family of chemicals that have similar toxicity and shared chemical characteristics. The dioxins and furans are not manufactured or produced intentionally but are created when other chemicals or products are made.
Where can furans be found?
Furan has been found in such canned or jarred foods as soups, sauces, beans, pasta meals, and baby foods. Data on furan in foods can be found on FDA’s website.
How do persistent organic pollutants affect the environment?
Persistent organic pollutants (POPs) are toxic chemicals that adversely affect human health and the environment around the world. Because they can be transported by wind and water, most POPs generated in one country can and do affect people and wildlife far from where they are used and released.
How does burning natural gas affect the environment?
Burning natural gas for energy results in fewer emissions of nearly all types of air pollutants and carbon dioxide (CO2) than burning coal or petroleum products to produce an equal amount of energy.
What are the effects of natural gas poisoning?
Natural gas is non-toxic (non-poisonous), but can cause death by suffocation if the gas displaces the air in a confined space. A person will experience the following effects as gas concentration increases: At 25 to 30% gas in air, the oxygen deficiency can cause ringing ears, euphoria, and unexplained behavioral changes.
Is natural gas a clean burning fossil fuel?
Natural gas is a relatively clean burning fossil fuel. Burning natural gas for energy results in fewer emissions of nearly all types of air pollutants and carbon dioxide (CO2) than burning coal or petroleum products to produce an equal amount of energy.
What are the advantages and disadvantages of natural gas?
In power plants, natural gas emits 50 to 60 percent less carbon dioxide (CO2) than regular oil or coal-fired power plants. It also emits greenhouse gases with a lower life cycle into the atmosphere. However, combustion also releases methane and lowers air quality.
