...request of the University, carbon monoxide levels were measured last week in Watson Rink, along the banks of the Charles and at other locations, under the direction of John Spengler, professor of Public Health. Potentially hazardous levels of carbon monoxide (CO) were found in the skating rink and levels exceeding National Air Quality standards were found in other locations...
...Carbon monoxide is a noxious gas which binds hemoglobin and prevents the uptake of oxygen. When an athlete is exposed to moderate amounts of CO he may suffer headaches and nausea, decreased visual acuity and reduced maximal work rates. As a consequence, the athlete is not able to judge time intervals correctly and his response time is decreased. In addition the athlete risks coronary artery disease. Harvard athletes are exposed to significant amounts of carbon monoxide when exercising in Watson Rink or running along the Charles--and the effects are magnified due to their increased breathing rate...
...Watson Rink the ice cleaning machine and cigarette smoke produce unsafe carbon monoxide levels. Air testing has shown that at ice level the average carbon monoxide level was 63 parts per million (ppm) during game time and reached as high as 192 ppm during peak levels of activity...
...hard-breathing Harvard hockey team these levels are dangerous. For instance, a Harvard iceman whose ventilation rate reaches 25 litres per minute after 80 minutes, at exposures of 60 ppm will incur a 10 per cent carboxyhemoglobin level--10 per cent of his oxygen carrying hemoglobin is bound by carbon monoxide. This means that the Harvard player is receiving oxygen as if he were at 12,000 feet above sea level...
...earlier evolution of qualities that we regard as uniquely human?" This need to impose a dramatic unity on unimaginable lengths of time can also lead to inconsistencies. Ardrey says at one point that science has failed to advance our knowledge of ourselves, and elsewhere discusses the value of carbon dating, molecular genetics and the study of coprolites-fossilized feces-in revealing our prehistoric past. He asserts that the fate of Neanderthal man is unknown, and two pages later says with equal certainty that Cro-Magnon man killed him off. Finally, he notes dourly the prevalence of a current "doomsday attitude...
