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) has determined that asbestos is a known carcinogen. It is known that asbestos causes cancer in people. There are two types of cancer caused by exposure to asbestos: cancer of the lung tissue itself and mesothelioma, a cancer of the membrane that surrounds the lung and other internal organs. Both of these are usually fatal. These diseases don't develop immediately, but show up only after many years.

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.

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.

In the course of mining, manufacturing and installing asbestos products, tiny asbestos fibers become airborne. Most inhaled fibers are cleared from the lungs within hours of inhalation. Coughing carries them to the throat in a layer of mucus, where they are either spit out, or swallowed, and make their way out of the body.

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 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.

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.

The Environmental Protection Agency (EPA) has determined that the carcinogenicity of toluene cannot be classified.

No studies are available on whether nitrobenzene causes cancer in people. In animals, breathing nitrobenzene resulted in an increase in liver, thyroid, and kidney tumors. The International Agency for Research on Cancer (IARC) has determined that nitrobenzene is possibly carcinogenic to humans.

The Department of Health and Human Services (DHHS) and the International Agency for Research on Cancer (IARC) have determined that beryllium is a human carcinogen. The EPA has determined that beryllium is a probable human carcinogen.

Laboratory tests in animals have shown that long-term exposure can cause cancer in mice. It is not known whether it causes cancer in humans. The International Agency for Research on Cancer (IARC) has concluded that chloroethane is not classifiable as to its carcinogenicity in humans.

There is no evidence that MTBE causes cancer in humans. One study with rats found that breathing high levels of MTBE for long periods may cause kidney cancer. Another study with mice found that breathing high levels of MTBE for long periods may cause liver cancer. The Department of Health and Human Services (DHHS), the International Agency for Research on Cancer (IARC), and the EPA have not classified MTBE as to its carcinogenicity.

Studies of laboratory animals and people show that most selenium compounds probably do not cause cancer. In fact, studies in humans suggest that lower-than-normal selenium levels in the diet might increase the risk of cancer. The International Agency for Research on Cancer (IARC) has determined that selenium and selenium compounds are not classifiable as to their carcinogenicity to humans.

The available studies in humans are inadequate to determine whether exposure to aniline can increase the risk of developing cancer in people. Rats that ate food contaminated with aniline for life developed cancer of the spleen. The International Agency for Research on Cancer (IARC) determined that aniline is not classifiable as to its carcinogenicity to humans. The EPA has determined that aniline is a probable human carcinogen.

We have no conclusive proof that lead causes cancer in humans. Kidney tumors have developed in rats and mice that had been given large doses of some kind of lead compounds. The Department of Health and Human Services (DHHS) has determined that lead and lead compounds are reasonably anticipated to be human carcinogens and the EPA has determined that lead is a probable human carcinogen.
