Symptoms of Poisoning with Arsenical Compounds
Find Products Containing this Chemical

- Garlic odor of breath and feces, metallic taste in mouth.
- Adverse GI effects predominate with vomiting, abdominal pain and rice-water or bloody diarrhea. GI effects may also include inflammation, vesicle formation and eventual sloughing of the mucosa in the mouth, pharynx and esophagus.
- Central nervous system effects are common: headache, dizziness, drowsiness and confusion.
- Symptoms may progress to include muscle weakness and spasms, hypothermia, lethargy, delirium, coma and convulsions.
- Renal injury is manifest as proteinuria, hematuria, glycosuria, oliguria, casts in the urine and in severe poisoning cases, acute tubular necrosis.
- Cardiovascular effects include shock, cyanosis and cardiac arrhythmia.
- Liver damage may be manifested by elevated liver enzymes and jaundice.
- Injury to blood-forming tissues may cause anemia, leucopenia and thrombocytopenia.
Chronic exposure may lead to:
- Muscle weakness, fatigue, anorexia, weight loss.
- Hyperpigmentation, hyperkeratosis.
- Peripheral neuropathy, paresthesia, paresis and ataxia.
- Inability to coordinate voluntary muscular movements.
- Subcutaneous edema in face, eyelids, and ankles.
- Stomatitis, white striations across the nails (Mees lines) and sometimes loss of nails or hair.
- Liver toxicity as indicated by hepatomegaly, jaundice, cirrhosis.
- Renal toxicity leading to oliguria, proteinuria, and hematuria.
- EKG abnormalities and peripheral vascular disease.
- Hematologic abnormalities.
- Cancer.

Symptoms of Arsenic acid Exposure

- Skin contact can cause burning, itching, thickened skin and color changes.
- Irritation of the nose and throat, and cause ulcers in the nose.
- High or repeated exposures can cause nerve damage, with "pins and needles", numbness and weakness of arms and legs; poor appetite, nausea, stomach cramps, vomiting, diarrhea and even death.

Indicates high toxicity in the given toxicological category. Indicates no available weight-of-the-evidence summary assessment. For additional information on toxicity from scientific journals or registration documents, see the "Additional Resources for Toxicity " section of the chemical detail page.
1. PAN Bad Actors are chemicals that are one or more of the following: highly acutely toxic, cholinesterase inhibitor, known/probable carcinogen, known groundwater pollutant or known reproductive or developmental toxicant. NOTE! Because there are no authoritative lists of Endocrine Disrupting (ED) chemicals, EDs are not yet considered PAN Bad Actor chemicals.

Organism Group Average Acute Toxicity Acute Toxicity Range
HoneybeesModerately ToxicModerately Toxic
Note: Population-level effects on honeybees may occur even if a pesticide has low acute toxicity. For example, certain pesticides interfere with honeybee reproduction, ability to navigate, or temperature regulation, any of which can have an effect on long-term survival of honeybee colonies. The neonicotinoids, pyrethroids and keto-enol pesticides are some types of pesticides causing one or more of these effects.
