Editors' Summary: The U.S. Supreme Court ruled on three takings cases in its 2004 term: Lingle v. Chevron U.S.A., Inc.; Kelo v. City of New London; and San Remo Hotel, Ltd. Partnership v. City & County of San Francisco. In Lingle, the Court struck down the "substantially advance" test set forth in Agins v. City of Tiburon. Kelo, which gained attention from the media and public, upheld the use of eminent domain for economic development purposes. And San Remo involved a relatively straightforward procedural issue.

One of the most fundamental tenets of toxicology is that "the dose determines the poison." This simple phrase provides the basis for the belief that all agents—chemicals and physical phenomena that are capable of producing some effect—have the potential to cause toxicity. Whether toxicity actually occurs is principally a matter of dose: the greater the exposure to a given agent, the more pronounced or severe the response of a cell or organism.
