Editors' Summary: Until recently, the regulation of chemical carcinogens and the regulation of radiological carcinogens developed independently. Different governmental agencies operating under different statutory directives were responsible for addressing the dangers from these carcinogens. As a result, different policies and practices were developed. This Article explores these differences and the record on resolving them. It first examines the history of federal regulation of chemical and radiological carcinogens and summarizes EPA's approach to risk assessments for them.

Editors' Summary: This Article addresses the effect of the U.S. Constitution's Takings Clause on the government's authority to protect environmental resources. An earlier Article, published in the May 1994 of ELR, analyzed bases for government regulation provided by limitations inherent in the property right itself.

Perhaps because it had never explicated the meaning of "temporary taking," and perhaps in part because its interest was kindled by the Kozinski dissent, the U.S. Supreme Court recently granted certiorari. The question is limited to:

Editors' Summary: Since 1910, the federal government has played a role in regulating pesticides. At first, the motive was to fight fraud, but as pesticides became more sophisticated and as environmental concerns grew, the government's regulatory efforts became more comprehensive. Now, near the dawn of bioengineered pesticides, with society confronting and reevaluating environmental risks, and with agencies facing fiscal challenges, pesticide regulation continues to evolve. It is a field of concern to the pesticide industry, of course, but in U.S.
