The International Agency for Research on Cancer has determined that 4,4'-methylenedianiline is possibly carcinogenic to humans. A study on people exposed to bread contaminated with 4,4'-methylenedianiline did not show an increased risk of cancer. An animal study showed cancer of the liver and thyroid after animals drank water over their lifetimes containing 4,4'-methylenedianiline.

Being treated by a kidney dialysis machine. Tiny amounts are released from the polyurethane parts of the machine when it is sterilized by radiation or heat.

Limited information is available on the effects of 4,4'-methylenedianiline on people's health. The available information shows that it can cause skin irritation and liver damage. People who accidentally ate bread baked from flour contaminated with 4,4'-methylenedianiline became ill with a flu-like condition, consisting of stomach and chest pains. They also exhibited jaundice, a yellowish coloring of the skin or internal organs caused by abnormal functioning of the liver.

Methylenedianiline is found in tiny particles in air which will settle to land or water in rain or snow. Most of the 4,4'-methylenedianiline in water will attach itself to particles and sink to the bottom sediment. It may take as long as 10 days for bacteria and microorganisms in soil to break down 4,4'-methylenedianiline.

Methylenedianiline can be measured in your urine to see if you have been recently exposed to the chemical. These tests can show you were exposed to 4,4'-methylenedianiline, but cannot predict the kind of health effects that might occur. These tests are not routinely available in doctor's offices and hospitals because they require special equipment.

The International Agency for Research on Cancer (IARC), the Department of Health and Human Services (DHHS), and the Environmental Protection Agency (EPA) have not reviewed tetryl to determine whether it is likely to cause cancer.

The Department of Health and Human Services (DHHS), the International Agency for Research on Cancer (IARC), and the Environmental Protection Agency (EPA) have not classified Lewisite as to its carcinogenicity. Both the DHHS and IARC have classified the blister agent H/HD (the sulfur mustard used in the Mustard-Lewisite mixture) as a human carcinogen. We to not know whether the Mustard-Lewisite mixture might also be a human carcinogen.

The International Agency for Research on Cancer (IARC) has classified nitrogen mustard HN-2 as probably carcinogenic to humans, based on evidence that it causes leukemia in humans and cancers of the lung, liver, uterus, and large intestine in animals.

The Department of Health and Human Services (DHHS), the International Agency for Research on Cancer (IARC), and the Environmental Protection Agency (EPA) have not classified phosgene oxime for carcinogenicity. There is no information to determine whether exposure to phosgene oxime might cause cancer.

The International Agency for Research on Cancer (IARC) has determined that one TPH compound (benzene) is carcinogenic to humans. IARC has determined that other TPH compounds (benzo[a]pyrene and gasoline) are probably and possibly carcinogenic to humans. Most of the other TPH compounds are considered not to be classifiable by IARC.

The U.S. Department of Health and Human Services (DHHS) has determined that hexachlorobenzene may reasonably be expected to be a carcinogen. Animals that ate hexachlorobenzene for months or years developed cancer of the liver, kidneys, and thyroid. There is no strong evidence that it causes cancer in people. A factory worker who breathed air for several years that contained many chemicals, but mostly hexachlorobenzene, developed liver cancer.

The Department of Health and Human Services, the International Agency for Research on Cancer, and the Environmental Protection Agency (EPA) have not classified CDFs for carcinogenicity. It is not definitely known if CDFs cause cancer in people. There are no cancer studies in animals that ate or breathed CDFs.

There are no human cancer data available for manganese. Exposure to high levels of manganese in food resulted in a slightly increased incidence of pancreatic tumors in male rats and thyroid tumors in male and female mice. The Environmental Protection Agency (EPA) has determined that manganese is not classifiable as to human carcinogenicity.

There are inadequate human cancer data available for all forms of mercury. Mercuric chloride has caused increases in several types of tumors in rats and mice, and methylmercury has caused kidney tumors in male mice. The EPA has determined that mercuric chloride and methylmercury are possible human carcinogens.

Few studies of workers indicate that PCBs were associated with certain kinds of cancer in humans, such as cancer of the liver and biliary tract. Rats that ate food containing high levels of PCBs for two years developed liver cancer. The Department of Health and Human Services (DHHS) has concluded that PCBs may reasonably be anticipated to be carcinogens. The EPA and the International Agency for Research on Cancer (IARC) have determined that PCBs are probably carcinogenic to humans.

There is no evidence that pyrethrins or pyrethroids causes cancer in people or in animals. The International Agency for Research on Cancer (IARC) has determined that the carcinogenicity to humans for three pyrethroids (deltamethrin, fenvalerate, permethrin) is not classifiable.

Usually, the cancer treatment, not the actual cancer, damages a man’s fertility. Radiation and chemotherapy kill cells that are in the middle of dividing and growing, when they are easier to damage. Cancer cells divide much more often than most normal body tissues, so they are killed off while normal cells survive. However, hair and sperm cells also grow constantly, making them sensitive to chemotherapy or radiation.

No information is available to show that 1,1,1-trichloroethane causes cancer. The International Agency for Research on Cancer (IARC) has determined that 1,1,1-trichloroethane is not classifiable as to its human carcinogenicity.

The International Agency for Research on Cancer has determined that chlordane is not classifiable as to its carcinogenicity to humans. Studies of workers who made or used chlordane do not show that exposure to chlordane is related to cancer, but the information is not sufficient to know for sure. Mice fed low levels of chlordane in food developed liver cancer.

The Department of Health and Human Services, the International Agency for Research on Cancer, and the Environmental Protection Agency (EPA) have not classified the nitrophenols as to their human carcinogenicity. animal study found no evidence of cancer when 4-nitrophenol was applied to the skin of mice, and no studies in people are available.

The Department of Health and Human Services (DHHS), the World Health Organization (WHO), and the EPA have determined that asbestos is a human carcinogen. It is known that breathing asbestos can increase the risk of cancer in people. There are two types of cancer caused by exposure to asbestos: lung cancer and mesothelioma. Mesothelioma is a cancer of the thin lining surrounding the lung (pleural membrane) or abdominal cavity (the peritoneum).

The Department of Health and Human Services (DHHS) has determined that nickel and certain nickel compounds may reasonably be anticipated to be carcinogens.

The Department of Health and Human Services (DHHS) has determined that cadmium and cadmium compounds may reasonably be anticipated to be carcinogens.

Long-term exposure to high levels of benzene in the air can cause leukemia, particularly acute myelogenous leukemia, often referred to as AML. This is a cancer of the bloodforming organs. The Department of Health and Human Services (DHHS) has determined that benzene is a known carcinogen. The International Agency for Research on Cancer (IARC) and the EPA have determined that benzene is carcinogenic to humans.

Some studies with mice and rats have suggested that high levels of trichloroethylene may cause liver, kidney, or lung cancer. Some studies of people exposed over long periods to high levels of trichloroethylene in drinking water or in workplace air have found evidence of increased cancer. Although, there are some concerns about the studies of people who were exposed to trichloroethylene, some of the effects found in people were similar to effects in animals.

The Department of Health and Human Services has determined that 1,3-butadiene may reasonably be anticipated to be a carcinogen. This is based on animal studies that found increases in a variety of tumor types from exposure to 1,3-butadiene. Studies on workers are inconclusive because the workers were exposed to other chemicals in addition to 1,3-butadiene.

Several studies have shown that ingestion of inorganic arsenic can increase the risk of skin cancer and cancer in the liver, bladder, and lungs. Inhalation of inorganic arsenic can cause increased risk of lung cancer. The Department of Health and Human Services (DHHS) and the EPA have determined that inorganic arsenic is a known human carcinogen. The International Agency for Research on Cancer (IARC) has determined that inorganic arsenic is carcinogenic to humans.

We do not know whether ammonia can cause cancer in humans or in laboratory animals. The Department of Health and Human Services (DHHS), the International Agency for Research on Cancer (IARC), and the EPA have not classified ammonia for carcinogenicity.

It is not known if phenol causes cancer in people. Cancer occurred in mice when phenol was applied to the skin several times each week for the lifetime of the animal. Phenol did not cause cancer in mice or rats when they drank water containing it for 2 years. The International Agency for Research on Cancer (IARC) has determined that phenol is not classifiable as to its carcinogenicity to humans.
