Lead is the most prevalent heavy metal contaminant. [24] As a component of tetraethyl lead, (CH 3 CH 2) 4 Pb, it was used extensively in gasoline during the 1930s–1970s. [25] Lead levels in the aquatic environments of industrialised societies have been estimated to be two to three times those of pre-industrial levels. [26]
Examples of activation-independent carcinogens include ultraviolet light, ionizing radiation and alkylating agents. [21] 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]

[4] 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. [5]
Researchers using high-tech air monitoring equipment rolled through an industrialized stretch of southeast Louisiana in mobile labs and found levels of a carcinogen in concentrations as much as 20 ...
The analysis, published in the journal Frontiers in Toxicology, builds upon research published earlier this year, which identified more than 900 chemicals as being potential mammory carcinogens ...
Cadmium is an extremely toxic industrial and environmental pollutant classified as a human carcinogen: Group 1, according to the International Agency for Research on Cancer; [4] Group 2a, according to Environmental Protection Agency (EPA); and a 1B carcinogen as classified by European Chemical Agency. [16] [17]
New tests done by the Environmental Working Group have found 21 oat-based cereals and snack bars popular amongst children to have "troubling levels of glyphosate." The chemical, which is the ...
The first type of carcinogen is the physical type which can be ultraviolet and ionizing radiation. The second type of carcinogens is defined as asbestos, tobacco smoke, alcohol, aflatoxin, and arsenic. The third type of carcinogen is biological which highlights infections that can be caused from viruses, bacteria, or parasites. [2]
