EPA TO OKAY HUMAN TESTS OF PESTICIDES Draft rule omits some safeguards sought by National Research Council

A LEAKED DRAFT EPA RULE

on using human volunteers for tests of pesticides and

toxic chemicals has drawn a sharp response from Congress.

The proposal follows some of the recommendations of a Feb­ruary 2004 National Research Council report on the subject. But the draft omits several safe­guards and allows certain exper­iments that NRC said should be prohibited.

For example, the draft pro­posal allows exposure studies on children if conducted during chil­dren's normal activities and not used to identify a toxic effect. NRC, in contrast, concluded that studies on pregnant women, as well as children, newborns, and prisoners, would generally be un­ethical. NRC also recommend­ed that EPA establish a review board to evaluate all human dos­ing studies, but the EPA propos­al does not require such a board. The agency says a review board "would unnecessarily confine EPA's discretion."

EPAs controversial proposal has led to conflicting amendments being passed in the Senate. On June 29, the Senate addressed pes­ticide testing in two amendments to the appropriations bill for in­terior and related agencies. One measure, by Sen. Barbara Boxer (D-Calif), prohibits EPA from spending any funds to consider third-party pesticide studies— those conducted by industry or outside organizations—in which humans are intentionally dosed. The second measure, by Sen. Conrad Burns (R-Mont.), in­structs EPA to conduct a thor­ough review of human pesticide dosing studies and to issue a final

rule on the conduct of such stud­ies within 180 days.

Last month, the House ap­proved a measure similar to the Boxer amendment.

EPAsays the draft proposal has not been reviewed by Adminis­trator Stephen L. Johnson and that the agency had not planned to re­lease the proposal until August. "EPAis taking the historic step of regulating, for the first time, sci­entific and ethical standards for accepting third-party human stud­ies, and it's unfortunate that mem­bers of Congress have chosen to politicize this important issue," the agency says in a statement.

Gates Foundation Awards 43 Grants For Global Health Research

A global health initiative that was launched in 2003 by the Bill & Melinda Gates Foun­dation has awarded 43 grants totaling

$436 million for a broad range of innovative re­search projects designed to prevent, treat, and cure diseases of the developing world.

The 43 projects are grouped under seven ma­jor goals:

• Develop improved childhood vaccines that do not require refrigeration, needles, or multi­ple doses.

• Create new vaccines to prevent malaria, tu­berculosis, and HIV infection.

• Develop new ways to prevent insects from transmitting diseases such as dengue.

• Discover ways to prevent drug resistance in infectious microorganisms.

• Create therapies to cure latent and chronic infections such as tuberculosis.

• Develop technologies to diagnose and track diseases more accurately in poor countries.

• Grow more nutritious versions of staple crops such as rice and cassava to combat mal­nutrition.
