“…Subjects in all three states are tested for visual acuity and contrast sensitivity as described previously (13). North Carolina and Virginia also assess color blindness and hue discrimination using standard methods (15,16). Vibrotactile perception threshold is measured in the North Carolina cohort using a portable biothesiometer (R. Fortier Ceramics Registered, Montreal, Canada) because of previous reports that this is a useful technique for detecting peripheral nervous system disease or dysfunction that may result from exposure to neurotoxic substances (17,18).…”

A variety of human symptoms have been associated with exposure to the dinoflagellate Pfiesteria and have been grouped together into a syndrome termed "possible estuary-associated syndrome." Prospective cohort studies of health effects associated with exposure to estuarine waters that may contain Pfiesteria spp. and related organisms are in progress in North Carolina, Virginia, and Maryland. The three studies recruited cohorts of 118-238 subjects who work or engaged in recreation in estuary waters. Baseline health and neuropsychological evaluations are conducted, and study subjects are followed prospectively for 2-5 years with periodic assessments of health and performance on a battery of neuropsychological tests. Health symptoms and estuary water exposure are recorded by telephone interviews or diaries every 1-2 weeks. Water quality information, including measurements of Pfiesteria spp., is collected in the areas where the subjects are working. Because it is not possible to measure individual exposure to Pfiesteria or a toxin produced by this organism, these studies examine surrogate exposure measures (e.g., time spent in estuary waters, in a fish kill area, or in waters where Pfiesteria DNA was detected by molecular amplification). Preliminary analyses of the first 2 years (1998-2000) of data indicate that none of the three ongoing cohorts have detected adverse health effects. However, there have not been any reported fish kills associated with Pfiesteria since the studies began, so it is possible that none of the study subjects have been exposed to toxin-producing Pfiesteria spp.

Over 250 adults and children were exposed to chlordane when the wooden building surfaces and soil around an apartment complex were sprayed in 1987. Two hundred-sixteen adults had neurobehavioral functions measured and completed questionnaires for symptom frequency, mood status, confounding factors, and medical, rheumatic, and respiratory disorders in 1994. Measurements included simple and choice reaction time, balance, blink reflex latency, color vision, cognitive, perceptual motor, memory, and recall functions. We analyzed 216 exposed and 174 referent adults. Age, educational level, weight, height, and gender ratio were similar for the exposed and referent groups. Performance of balance, reaction times, Culture Fair, digit symbol, verbal recall, and trail-making were significantly impaired in exposed persons compared to referents. Mood-state scores were elevated, as were the frequencies of respiratory, neurobehavioral, and rheumatic symptoms. In contrast, long-term memory function was similar in both groups, consistent with its status before exposure. There was no identified bias or confounding factors. Chlordane exposure was associated with protracted impairment of neurophysiological and psychological functions. The central nervous system is the most important target of chlorinated cyclodiene insecticides. Human exposure should be prohibited. Images p690-a

Suggested color combinations and actually existing color combinations for apartment bathrooms are empirically examined in this experiment to test the levels of color discernment for both normal and elderly vision. A YA3 filter was employed for simulating yellowed eyesight that commonly affects the color vision of the elderly. Results of the study imply most color combinations in apartment bathrooms found in Korea today are difficult to discern for both the elderly and young adults with normal vision. In elderly vision, the high discernment levels of the suggested combinations support the efficiency of the color schemes developed in the previous study. The color schemes were complemented and improved through analysis of other combinations, which showed low discernment levels in normal or elderly vision. In conclusion, with the perspective of universal design in mind, this study suggested color schemes that are easily discernable for both elderly and normal vision while maintaining the original mood.
