Mercury Mercury has no known beneficial role in human metabolism, and its ability to affect the distribution and retention of other heavy metals makes it one of the most dangerous toxic metals (Houston 2011). Mercury toxicity can arise from ingestion of metallic mercury or mercury salts (which are generally poorly bioavailable) or by inhalation of mercury vapor (which is readily absorbed) (ATSDR 2001). The relatively high solubility and stability of certain mercury salts in water enables them to be readily taken up and biotransformed to methylmercury by certain fish; these forms are readily absorbed through the GI tract and are becoming a major source of mercury exposure in humans (Houston 2011). Dimethylmercury, a mercury compound chemically synthesized in the laboratory, can also be absorbed through the skin, and several cases of fatal exposure among laboratory workers have been reported (Nierenberg 1998; Bernhoft 2012). Although humans can excrete small amounts of mercury in urine or feces as well as via exhalation or sweating, they lack an active robust mechanism for mercury excretion, allowing levels to accumulate with chronic exposure (Houston 2011; Sällsten 2000; Houston 2011). Mercury, particularly when inhaled as mercury vapors, can distribute to many organs, but may concentrate in the brain and kidneys (ATSDR 2001). It can also cross the placenta and be found in breast milk (Yang 1997). Mercury exerts its toxic effects by competing with and displacing iron and copper from the active site of enzymes involved in energy production; this induces mitochondrial dysfunction and oxidative damage (Houston 2011). Mercury can also directly accelerate the oxidative destruction of cell membranes and LDL cholesterol particles as well as bind to and inactivate the cellular antioxidants N-acetyl cysteine, alpha-lipoic acid, and glutathione (Houston 2011). Because of its effect on cellular defense and energy generation, mercury can cause widespread toxicity and symptoms

The deleterious effect ionizing radiation has on human tissue can be divided into two types: non-stochastic (deterministic) or stochastic effects. Deterministic (Non-Stochastic) Effects Deterministic effects only occur once a threshold of exposure has been exceeded. The severity of deterministic effects increases as the dose of exposure increases. Because of an identifiable threshold level, appropriate radiation protection mechanisms and occupational exposure dose limits can be put in place to reduce the likelihood of these effects occurring. Mechanisms Deterministic effects are caused by significant cell damage or death. The physical effects will occur when the cell death burden is large enough to cause obvious functional impairment of a tissue or organ. Skin Erythema/Necrosis/Epilation Erythema occurs 1 to 24 hours after 2 Sv have been received. Breakdown of the skin surface occurs approximately four weeks after 15 Sv have been received. Epilation is reversible after 3 Sv but irreversible after 7 Sv and occurs three weeks following exposure. Cataract Cataract occurs due to accumulation of damaged or dead cells within the lens, the removal of which cannot take place naturally. Cataract occurs after 2 to 10 Gy have been received, but may take years to develop. Sterility Radiation can impair oocyte function, leading to impaired or non-fertility. The radiation dose required to have this effect decreases with age due to falling total oocyte numbers. Similarly, radiation exposure to the testes can result in temporary or permanent azoospermia. Permanent sterility occurs after 2.5 to 3.5 Gy have been received by the gonads. Radiation Sickness Radiation sickness (correctly termed acute radiation syndrome) involves nausea, vomiting, and diarrhea developing within hours or minutes of a radiation exposure. This is due to deterministic effects on the bone marrow, GI tract, and CNS.
