Metal toxicity or metal poisoning is the toxic effect of certain metals in certain forms and doses on life.Some metals are toxic when they form poisonous soluble compounds. . Certain metals have no biological role, i.e. are not essential minerals, or are toxic when in a certain for
Like most toxic gases, the dose inhaled determines the toxicity on the respiratory tract. Occupational exposures constitute the highest risk of toxicity and domestic exposure is uncommon. Prolonged exposure to low concentration of the gas may have lethal effects, as can short-term exposure to high concentrations like chlorine gas poisoning.
Bromoform can be absorbed into the body by inhalation and through the skin. The substance is irritating to the respiratory tract, the eyes, and the skin, and may cause effects on the central nervous system and liver, resulting in impaired functions. Its LD 50 is 7.2 mmol/kg in mice, or 1.8 g/kg. The International Agency for Research on Cancer ...
Cutaneous squamous-cell carcinoma is the second-most common cancer of the skin (after basal-cell carcinoma, but more common than melanoma). It usually occurs in areas exposed to the sun. Sunlight exposure and immunosuppression are risk factors for SCC of the skin, with chronic sun exposure being the strongest environmental risk factor. [26]
Skin cancer is the most commonly diagnosed form of cancer in humans. [11] [12] [13] There are three main types of skin cancers: basal-cell skin cancer (BCC), squamous-cell skin cancer (SCC) and melanoma. [1] The first two, along with a number of less common skin cancers, are known as nonmelanoma skin cancer (NMSC).
Other toxic effects such as endocrine disruption (notably blocking of thyroid system functioning) and neurotoxicity are known. [8] The bromine analogues of PCBs are polybrominated biphenyls (PBBs), which have analogous applications and environmental concerns. An estimated 1.2 million tons have been produced globally. [9]

The most common health hazard of radiation is sunburn, which causes between approximately 100,000 and 1 million new skin cancers annually in the United States. [ 3 ] [ 4 ] In 2011, the World Health Organization (WHO) and the International Agency for Research on Cancer (IARC) have classified radiofrequency electromagnetic fields as possibly ...
