Learn About the Dangers of Arsenic Exposure
Arsenic Exposure
Humans are generally exposed to arsenic
through drinking contaminated water, breathing contaminated air, or eating
contaminated foods.
If you are living near a hazardous waste site or an
area with natural arsenic in rocks, the dangers are significantly higher and you
may have a possible Arsenic lawsuit.
At higher levels, inorganic arsenic
is fatal. Lower levels of arsenic can cause nausea and vomiting, decreased
production of red and white blood cells, abnormal heart rhythm, damage to blood
vessels, and a sensation of "pins and needles" in hands and
feet.
Exposure to lower levels for a long time can cause a discoloration
of the skin and the appearance of small corns or warts on limbs and
torso.
Studies have shown that inorganic arsenic can increase the risk of
lung cancer, skin cancer, bladder cancer, liver cancer, kidney cancer, and
prostate cancer.
The World Health Organization, the Department of Health
and Human Services, and the Environmental Protection Agency have identified
arsenic as a carcinogen.
Arsenic poisoning is difficult to without
tests, as many common illnesses carry symptoms.
To prevent a massive
arsenic epidemic in the United States, the Environmental Protection Agency
decided in 2001 to develop a strict new arsenic standard, the Safe
Water Drinking Act.
Public water systems must comply with the 10 parts
per billion (ppb) standard beginning January 23, 2006, down from the current
maximum contaminant level if 50 ppb.
Synonyms include arsenic oxide,
arsenious acid, arsenious oxide, arsenious trioxide, arsenous acid anhydride,
crude arsenic, arsenolite, and white arsenic.
- Persons whose clothing or skin is contaminated with arsenic trioxide can secondarily contaminate rescuers by direct contact or through release of inhalable dust.
- Arsenic trioxide is an odorless, tasteless, white or transparent nonflammable solid.
- Arsenic trioxide is readily absorbed if inhaled or ingested, but only slowly absorbed through the skin. Toxicity usually results from ingestion.
Description
There are many forms of arsenic, but this medical Management Guideline focuses specifically on arsenic trioxide (As2O3), one of the most toxic and prevalent forms.
Arsenic trioxide is a white or transparent solid in the form of glassy, shapeless lumps or a crystalline powder that resembles sugar.It has no odor or taste.
It forms readily when elemental metallic arsenic is heated to high temperatures or burned.
When arsenic trioxide is burned, it releases toxic fumes and arsine gas which is highly toxic.
Routes of Exposure
Arsenic trioxide dust is readily absorbed from the lungs, but inhaled quantities are usually insufficient to cause acute systemic toxicity. Arsenic trioxide has no odor. Thus, odor provides no warning of hazardous airborne concentrations.
Direct contact with arsenic trioxide dust can cause localized skin irritation, but systemic absorption through the skin is negligible.
Skin contact is unlikely to cause systemic effects unless the dermal barrier is compromised. Arsenic trioxide dust is irritating to the eyes.
Ingestion is the most important route of acute exposure of arsenic trioxide.
Ingested arsenic trioxide is quickly absorbed and can be extremely hazardous.
Significant tissue and organ damage and death may result. Most acute intoxications are from suicidal or homicidal ingestion.
Health Effects
- Toxic effects of arsenic trioxide usually result from ingestion. Small
amounts of arsenic trioxide can lead to multiple organ damage and
death.
Acute signs and symptoms include nausea, vomiting, diarrhea, gastrointestinal hemorrhage, cerebral edema, tachycardia, dysrhythmias, and hypovolemic shock. Symptoms are dose dependent and can be delayed. - Dermal contact and inhalation of airborne arsenic trioxide can cause localized irritation and usually does not result in systemic effects.
Act Now! It is essential that you inquire about your Arsenic concern as soon as possible. Your individual state's law may limit your time to bring a legal claim to protect your rights. Your legal review is free and there is no commitment. You case will be evaluated immediately, so get started on your claim today!
