11   TOXICOLOGICAL INFORMATION

Likely Routes of Exposure:  Inhalation, skin and eyes.

Symptoms of Exposure:  May cause irritation to skin and eyes and systemic poisoning with symptoms including abdominal pain, nausea, vomiting and diarrhea.

Acute and Chronic Effects:

Arsenic Compounds:  Arsenic compounds are mainly absorbed through the gastrointestinal tract, but some absorption may occur through intact skin or inhalation. Acute arsenic ingestion generally produces signs and symptoms within 30 minutes but symptoms may be delayed for several hours if ingested with food. Effects include vomiting, abdominal pain and diarrhea, followed by numbness and tingling of the extremities, muscle cramping, and death, in extreme cases. The first signs of long-term exposure to high levels of inorganic arsenic are usually observed in the skin, and include pigmentation changes, skin lesions, and hard patches on the palms and soles of the feet (hyperkeratosis). Cases of acute arsenical poisoning due to inhalation are exceedingly rare in industry. Increased mortality from multiple internal organ cancers (liver, kidney, lung, and bladder) and an increased incidence of skin cancer have been observed in populations consuming drinking water high in inorganic arsenic, and increased lung cancer mortality is associated with populations exposed primarily through inhalation.

Selenium Compounds:  Inhalation of selenium compounds may cause respiratory, gastrointestinal, and cardiovascular effects, as well as irritation of the skin and eyes. Fatalities following inhalation exposure to selenium compounds have not been reported. Most of the information concerning effects in humans following exposure to selenium and selenium compounds is for exposure via ingestion. Symptoms of chronic selenium toxicity may include hair and nail brittleness and loss, gastrointestinal disturbances, skin rash, garlic breath odor, fatigue, irritability, nervous system abnormalities, and possible damage to heart and liver. Water-soluble selenium compounds are probably more toxic than elemental selenium. Selenium is an essential trace element in humans and animals.

V.  HEALTH HAZARD INFORMATION

 


Effects of Exposure:

 

Inorganic arsenic compounds are confirmed human carcinogens producing tumors of the mouth, esophagus, larynx, bladder, and para nasal sinus.  A recognized carcinogen of the skin, lungs, and liver.  Poisoning from arsenic compounds may be acute or chronic.  Acute poisoning usually results from swallowing arsenic compounds.  Chronic from either swallowing or inhaling (Sax, Dangerous Properties of Industrial Materials, eighth edition).

 

Selenium compounds are poison by inhalation and intravenous routes.  Some selenium compounds are experimental carcinogens.  Long-term exposure may be a cause of amyotrophic lateral sclerosis in humans, just as it may cause “blind staggers” in cattle.  Elemental selenium has low acute systemic toxicity but dusts or fumes can cause serious irritation of the respiratory tract (Sax, Dangerous Properties of Industrial Materials, eighth edition).

 

Acute Effects:

 

Inhalation:  DANGER-POISON.  May cause irritation to the respiratory system, garlic odor of the breath, pallor, nervousness and depression.

Ingestion:  DANGER-POISON.  May cause systemic gastrointestinal and skin effects and acute arsenic poisoning.

Skin:  May cause irritation and skin abnormalities.

Eye:  May cause irritation.

 

Chronic Effects:

 

Inhalation:  DANGER-POISON.  May cause bronchitis, chronic arsenic poisoning, ulceration of the nasal septum, liver damage and cancer/disease of the blood, kidneys and nervous system.

Ingestion:  DANGER-POISON.  May cause chronic arsenic poisoning, gastrointestinal disturbances, liver damage and cancer/disease of the blood, kidneys and nervous system.

Skin:  May cause irritation, occasional ulceration, spotty pigmentation, dermatitis, skin cancer and keratosis (especially on soles and palms).

Eye:  May cause disturbances, such as blurred vision.

 

Target Organs:  may effect the upper respiratory system, eyes, skin, blood, liver, kidneys, skin, lungs and lymphatic system.

Carcinogenicity:  NTP:  Yes              IARC Monographs:  Yes    OSHA Regulated:  Yes

Medical Conditions Possibly Aggravated:  Pre-existing skin and respiratory disorders.

 

EMERGENCY AND FIRST AID PROCEDURES:

 

INHALATION:  Remove from exposure, keep warm and quiet, give oxygen if breathing is difficult, seek immediate medical attention.

INGESTION:  If conscious, give 1-2 glasses of milk or water and induce vomiting, call a physician immediately.  Never give anything by mouth to an unconscious person.

SKIN:  Remove contaminated clothing from affected area, brush material off skin, wash affected area with mild soap and water, seek medical attention immediately.

EYES:  Flush eyes with lukewarm water, lifting upper and lower lids, for at least 15 minutes, and seek immediate medical attention.
