More formally, it is a biological assay to assess the mutagenic potential of chemical compounds. [1] A positive test indicates that the chemical is mutagenic and therefore may act as a carcinogen, because cancer is often linked to mutation. The test serves as a quick and convenient assay to estimate the carcinogenic potential of a compound ...
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]
Hazardous chemicals present physical and/or health threats to workers in clinical, industrial, and academic laboratories. Laboratory chemicals include cancer-causing agents (carcinogens), toxins (e.g., those affecting the liver, kidney, and nervous system), irritants, corrosives, sensitizers, as well as agents that act on the blood system or damage the lungs, skin, eyes, or mucous membranes.
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 ...
Chemical hazards typically found in laboratory settings include carcinogens, toxins, irritants, corrosives, and sensitizers. Biological hazards include viruses, bacteria, fungi, prions, and biologically derived toxins, which may be present in body fluids and tissue, cell culture specimens, and laboratory animals.
A carcinogen (/ k ɑːr ˈ s ɪ n ə dʒ ən /) is any agent that promotes the development of cancer. [1] Carcinogens can include synthetic chemicals, naturally occurring substances, physical agents such as ionizing and non-ionizing radiation, and biologic agents such as viruses and bacteria. [2]
The presence of such an adduct indicates prior exposure to a potential carcinogen, but it does not necessarily indicate the presence of cancer in the subject animal. DNA adducts are researched in laboratory settings. A typical experimental design for studying DNA adducts is to induce them with known carcinogens. A scientific journal will often ...
