Multiple chemical sensitivity (MCS) is an unrecognized and controversial diagnosis characterized by chronic symptoms attributed to exposure to low levels of commonly used chemicals. [1] [2] Symptoms are typically vague and non-specific. They may include fatigue, headaches, nausea, and dizziness.
Acute exposure to these decomposition products can result in symptoms such as headaches, nausea, and irritation of the eyes, nose, or throat. [10] Engine bearing seals are installed to ensure that critical engine bearings are continuously lubricated, and to prevent engine oil from leaking into the compressed air stream. Engine seals will leak a ...
Toxic encephalopathy is a neurologic disorder caused by exposure to neurotoxic organic solvents such as toluene, following exposure to heavy metals such as manganese, as a side effect of melarsoprol treatment for African trypanosomiasis, adverse effects to prescription drugs, or exposure to extreme concentrations of any natural toxin such as cyanotoxins found in shellfish or freshwater ...
Exposure to harmful solvents has also been linked to parosmia specifically by damaging ORNs. [8] Damage to these neurons could render them unable to correctly encode a signal representing a particular odor, which would send an erroneous signal to the odor processing center, the olfactory bulb. This miscommunication, in turn, leads to the signal ...
Exposure to the coplanar stereoisomer 3,3',4,4',5,5'-hexabromobiphenyl (but not the non-coplanar stereoisomer) in genetically susceptible mice is known to cause immunotoxicity and disorders related to the central nervous system, and even at doses as low as 2.5 mg/kg, excess neonatal fatalities are observed (LD 50 is from 5–10 mg/kg).

Ergotism (pron. / ˈ ɜːr ɡ ə t ˌ ɪ z ə m / UR-gət-iz-əm) is the effect of long-term ergot poisoning, traditionally due to the ingestion of the alkaloids produced by the Claviceps purpurea fungus—from the Latin clava "club" or clavus "nail" and -ceps for "head", i.e. the purple club-headed fungus—that infects rye and other cereals, and more recently by the action of a number of ...
Signs of ethylene glycol poisoning depend upon the time after ingestion. [6] Symptoms usually follow a three-step progression, although poisoned individuals will not always develop each stage. [7] [8] Stage 1 (30 minutes to 12 hours) consists of neurological and gastrointestinal symptoms and looks similar to alcohol poisoning. [9]
