...alone, more than 400 totally new chemicals are introduced each year. They kill bugs, clean carpets, run automobiles and wash dishes. Some of them even fight disease. But when their usefulness is ended, they often find their way-as waste-into the air people breathe, the water they drink and the food they eat. Often invisible and immune to bacteriological attack, they damage plants, kill fish, slip undetected through sewage-treatment plants, and blanket entire cities with clouds of noxious vapor. Some, like sulphur dioxide, are clearly toxic-memorably so in the five-day siege of sulphurous smog in Donora...
What's in the Water...
...decades the U.S. has prided itself on the purity of its drinking water. Today in many places the boast rings hollow.

Necessity has forced Omaha to build one of the nation's finest water-purification plants, purchase $36,000 worth of chlorine a year. Still, says a Nebraska sanitation official, the water at times tastes "like hell-fire." In St. Louis County, residents have...
Swiss Psychologist Bärbel Inhelder suggests some translations. For example, a five-year-old thinks that a tall glass contains more water than a flat bowl. Shown that glass and bowl contain equal amounts, he is learning the principle of the invariance of quantities. In fact, a grade school teacher with a roulette wheel may turn out students more skilled in probabilistic reasoning than a college professor with a course in statistics...

With it youngsters can keep the beat to a wacky lament of a dying rancher called Tie Me Kangaroo Down, Sport.* Australian parents are wobbling under the board's gloop. The craze has spread to Great Britain, where already 100,000 records have brought the resonant beat of the wobble board. Last week there...
