Organic Chemical Pollution: Petroleum, Pesticides, and Detergents,e is the result of new compounds developed for consumer use rather than of an increased use of a few known compounds. The environmental impact of using these compounds has only slowly become apparent, and in many cases the findings have caused serious concern.冒烟 发表于 2025-3-23 19:05:19

Radioactivity, that radiation is continuously released from uranium-containing minerals, just a few months after Roentgen’s discovery of X rays in November, 1895. But only within the last 30 years has concern over man-made radioactivity arisen, as a result of the discovery of fission and its use in weapons that rsacrum 发表于 2025-3-24 05:05:58
Abundant, Clean Energy,travel, the production of goods from factories are all very energy dependent and their availability to average members of the population is clearly a function of the ratio of the price per unit of energy to the price of a day’s work. In the material sense, there were no radical changes in the way peFOIL 发表于 2025-3-24 10:34:43
The Hydrogen Economy,se with hydrogen. Thoughts concerning this were expressed in the United States in respect to a desire to avoid pollution from automobile exhausts, but they spread to the concept that hydrogen would be introduced into industry to replace natural gas as it was exhausted. Thus, one could see the possib独白 发表于 2025-3-24 12:37:51

Notes on Electrochemical Transportation,re three possible solutions to the dilemma we are in, i.e., that of wishing to have good transportation in order that our lives may continue in the same form as hitherto, and knowing that our present mode of transportation is not possible in the long term. The first two solutions are to use methanol最小 发表于 2025-3-24 20:37:24

Possible Climatic Changes from Carbon Dioxide Increase in the Atmosphere,mely low, and heating due to ultraviolet radiation absorption by ozone and cooling due to infrared emission by ozone and carbon dioxide become predominant. In the mesosphere, above 50 km, the cooling effect of carbon dioxide is the most important.
