The carcinogenity of chromate dust has been documented since the late 19th century, when workers in a chromate dye company were found to exhibit high incidence of cancer. [ 12 ] [ 13 ] Chromate enters cells by means of the same transport mechanism that carries sulfate and phosphate ions into cells.
Estrogen therapy, postmenopausal NB There is "evidence suggesting lack of carcinogenicity" for estrogen-only menopausal therapy in humans and colorectal cancer. An inverse association has been observed between estrogen-only menopausal therapy and cancer of the colorectum. Leather dust; Mineral oils, untreated or mildly treated
The use of personal protective equipment may substantially reduce the risk of adverse health effects from contact with hazardous materials. [2] Long-term exposure to chemical hazards such as silica dust, engine exhausts, tobacco smoke, and lead (among others) have been shown to increase risk of heart disease, stroke, and high blood pressure.

The general population and people living near hazardous waste sites may be exposed to cadmium in contaminated food, dust, or water from unregulated or accidental releases. Numerous regulations and use of pollution controls are enforced to prevent such releases.
A video on cleaning dust from workers' clothing. Occupational dust exposure occurs when small particles are generated at the workplace through the disturbance/agitation of rock/mineral, dry grain, timber, fiber, or other material. When these small particles become suspended in the air, they can pose a risk to the health of those who breath in ...
A closed system drug transfer device or "CSTD" is a drug transfer device that mechanically prohibits the transfer of environmental contaminants into a system and the escape of hazardous drug or vapor concentrations outside the system. Open versus closed systems are commonly applied in medical devices to maintain the sterility of a fluid pathway.
A person’s immune system is able to fight off many diseases, but it tends to be ineffective against cancer because of a mechanism called immune tolerance. Scientists find dangerous parasite that ...
There is no long-term research concerning the cancer risk related to the potentially small level of exposure to the identified carcinogens in the e-cigarette vapor. [132] Their long-term effect on risk of developing cancer is not known. [208] Their long-term use is anticipated to raise the risk of developing lung cancer. [209]
