Medical treatment of individuals with overt lead intoxication involves decontamination, supportive care, and judicious use of chelating agents.
Adults with overt lead intoxication will generally experience improvement in symptoms after removal from lead exposure and decline in blood lead concentration.
The serious public health problem of overt lead intoxication from eating lead-based paint has tended to obscure low level toxicity which may be related to atmospheric lead pollution.
Thus, a 16 g bat should require 1.03 ml of ethanol sugar water to achieve a BAC of 0.11 g 100 ml−1 [41], [41], which we expected would produce overt effects of intoxication.
The developmental neurotoxicity of organophosphate pesticides occurs at doses below the threshold for overt symptoms of intoxication, or even lower than that required for cholinesterase inhibition, the standard biomarker for exposure and risk assessment (reviewed by Slotkin 1999, 2004, 2005).
In this regard, not all people living in this area of endemic arsenicosis show overt signs of arsenic intoxication (Liu et al. 2002; Yang et al. 2006; Zhang et al. 2006), so some differences in sensitivity might be expected.
Where the degree of synergism was severe (e.g., for pairings of diazi-non and malathion), enhanced AChE inhibition (i.e., > 90%) corresponded to overt signs of anticholinesterase intoxication and death.
Chest x-ray findings of increased interstitial markings, atelectesis, overt pulmonary edema, or acute respiratory distress syndrome are also nonspecific and only present in inhalational intoxications of SEB (5 ).
