Rorschach Responses at Four Exposure Levels

Perceptual and Motor Skills, 1959
The purpose of the present study was to further clarify the role of stimulus exposure time as a variable which affects responses to projective material. Presentation of the standard Rorschach cards over a series of exposure times, ranging from .03 sec.

Sources of variability in levels and exposure to trihalomethanes

Environmental Research, 2007
In the framework of a cohort study of pregnant women conducted in Brittany (France), we assessed the exposure to trihalomethanes (THM) during pregnancy in a subset by evaluating (1) potential sources of variability in household THM levels; (2) the between- and within-subject variability in THM levels; (3) THM levels in swimming pools; and (4) the role ...

Levels of exposure from drinking water

Food and Chemical Toxicology, 2000
The relative exposure from drinking water is generally small, although there is a lack of information on total daily intake of individual organic micropollutants. There are, however, a few exceptions. Materials used in domestic distribution systems (lead, copper and plastics) may cause a deterioration of the water quality, especially in stagnant water.

Health effects of low-level exposures

Environmental Science & Technology, 1984
One of the goals of environmental epidemiology is to ascertain and quantify the relationships that exist between long-term, low-level exposures to pollutants and the impairment of bodily functions or the development of chronic diseases. Progress in meeting this goal was reported at the Fifth Annual Symposium of Environmental Epidemiology held in ...

Risk assessment of low-level exposures

IEEE Power Engineering Review, 1994
This presentation contends that in cancer-risk assessments employed by the US Environmental Protection Agency, assumptions are made that exaggerate risks by large factors. Among these is an important but unproven hypothesis that results obtained by administering huge doses of substances are predictive of effects of minuscule doses. To calculate effects
