In 1996, the International Agency for Research on Cancer (IARC) reviewed the medical data and classified crystalline silica as "carcinogenic to humans." The risk was best seen in cases with underlying silicosis, with relative risks for lung cancer of 2–4. Numerous subsequent studies have been published confirming this risk.
[1] [2] Depending on extent and severity, it may cause death within months or years, or it may never produce symptoms. It is usually an occupational lung disease , typically from years of dust exposure during work in mining; [ 5 ] textile milling; shipbuilding, ship repairing, and/or shipbreaking ; sandblasting ; industrial tasks; rock drilling ...
The time from exposure to a carcinogen to the development of cancer is known as the latency period. For most solid tumors in humans the latency period is between 10 and 40 years depending on cancer type. [22] For blood cancers, the latency period may be as short as two. [22]
The alkali–silica reaction (ASR), also commonly known as concrete cancer, [3] is a deleterious internal swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive amorphous (i.e., non-crystalline) silica found in many common aggregates, given sufficient moisture.
The international pictogram for chemicals that are sensitising, mutagenic, carcinogenic or toxic to reproduction. Reproductive toxicity refers to the potential risk from a given chemical, physical or biologic agent to adversely affect both male and female fertility as well as offspring development. [1]
IARC group 1 Carcinogens are substances, chemical mixtures, and exposure circumstances which have been classified as carcinogenic to humans by the International Agency for Research on Cancer (IARC). [1] This category is used when there is sufficient evidence of carcinogenicity in humans.
People are ingesting borax. Also known by its chemical name sodium borate decahydrate, borax is a salt typically used to kill ants and boost laundry detergent, among other household cleaning needs ...
Arsenic poisoning (or arsenicosis) is a medical condition that occurs due to elevated levels of arsenic in the body. [4] If arsenic poisoning occurs over a brief period of time, symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood. [1]
