Oevere toxicological responses have been associated with certain chloro- dibenzodioxins. One of these responses is chloracne, a folliculosis first associated with skin contamination by chlorohydrocarbons in 1899 (3). Serious outbreaks of chloracne-like lesions associated with runaway reactions in the production of 2,4,5-trichlorophenol occurred in Germany in the early 1950 s (5). 2,4,5-Trichlorophenol itself does not cause acne (S), but the contaminants which may be formed in the uncontrolled production of 2,4,5-trichlorophenol are extremely potent acnegens (5). 2,3,7,8-Tetrachlorodibenzo-p-dioxin and tri- and tetra-... [Pg.55]

Tissue damage occurs within minutes of exposure to vesicants, but clinical effects may not appear for up to 24 hours. Mixtures such as HL (C03-A010) contain lewisite (C04-A002) and will produce an immediate burning sensation on contact with the skin or eyes. Some agents are rapidly absorbed through the skin and extensive skin contamination may cause systemic damage. [Pg.145]

These agents rapidly permeate through the skin. Extensive skin contamination can damage susceptible tissue including blood cells and the liver. Casualties may develop signs of systemic arsenic toxicity including diarrhea, damage to the liver, kidneys, nervous system, red blood cells, and the brain. [Pg.198]

Utilization of coal and oil shale to produce liquid and gaseous synfuels results in the generation of many hazardous sub-tances. Workers in these synfuel plants are likely to be exposed to potentially carcinogenic materials present in coal tars and oils. Among the various pathways of exposure, skin contamination by direct contact transfer or by adsorption of vapors and particulates into the skin presents a serious occupational health hazard. The skin irritant and potential carcinogenic properties of raw syncrudes and their distillate fractions have been reported (1. 2, 3). [Pg.269]

This paper reports on research involved the design, construction, and evaluation of a portable instrument, a "luminoscope", for detecting skin contamination by coal tars via induced fluorescence. The instrument has been used in the laboratory to measure the fluorescence of various coal tars and recycle solvents from liquefaction processes spotted on filter paper on rat and on hamster skin. The practical use of the devices in field test measurements to monitor skin contamination of workers at coal gasifier is discussed. The paper also discusses the practicality and usefulness of the luminescence method for detecting skin contamination. [Pg.269]

Monitoring skin contamination at a coal gasifier. Recently the luminoscope was field tested at a coal gasifier facility. The purpose was to evaluate the performance of the prototype apparatus in a real-life workplace environment and to test the applicability of the instrumental concept in actual measurements. The skin contamination survey was carried out on six workers during two work-shifts. All measurements were carried out before and after washing. The portions of the workers bodies most likely to be directly exposed to coal and tar are those not protected by clothing, e.g., hands, arms, and faces. The measurements performed during this field trip were restricted only to arms and hands. [Pg.278]

This paper describes the luminoscope, a simple laboratory-constructed, portable luminescence detector designed specifically for monitoring occupational skin contamination. The instrument design is based upon a fiberoptics waveguide. The instrument is suitable for detecting trace amounts of various coal tars and has recently been field tested at a coal conversion facility. [Pg.280]

Serum TSH and thyroxine concentrations have been measured 57 days after birth in 365 healthy newborns whose umbilical stump had been treated with 10% povidone-iodine (41). The prevalence of high TSH concentrations was significantly higher in this group than in the general population (3.1% versus 0.4%), as was the rate of transient hypothyroidism (2.7% versus 0.25%). All the children were normal when retested 1 week later. Transient hypothyroidism due to skin contamination with povidone-iodine occurred in a neonate with an omphalocele (42). [Pg.332]

Highly toxic. Causes skin, eye, and respiratory system mutation. Acute effects include anorexia, nausea, vomiting, diarrhea, excessive salivation, pupillary constriction, broncho constriction, muscle twitching, convulsions, coma, respiratory failure. Special precautions are necessary to prevent inhalation and skin contamination.1 LD50 (oral rat) 13 mg/kg. LD50 (dermal rat) 21 mg/kg.

A significant correlation (r=0.71) was found between exposure levels and postshift, urinary chromium in workers exposed to chromium(VI) as chromium trioxide in the chrome plating industry. The urinary chromium level of 5.2 pg/L reflects a time-weighted average exposure of 0.002 mg chromium(VI)/m3. This correlation was obtained by excluding workers with obvious skin contamination (Lindberg and... [Pg.260]

Toxicity. Severe toxicity may result after ingestion or skin contamination with greater than 1 g, and fatalities have occurred after the ingestion of more than 2 g and after excessive skin contamination. The maximum permissible atmospheric concentration is 0.5 mg/m. ... [Pg.445]

A radiological incident may be as dramatic as a terrorist attack or as mundane as mild skin contamination from a minor spill. Radiological incidents have resulted in death from radiation sickness, but the vast majority of cases simply require decontamination and monitoring. [Pg.521]
