— Three decades after removing lead from gasoline, the Environmental Protection Agency is slashing the amount of the toxic metal that will be allowed in the nation's air by 90 percent.

EPA officials, under a federal court order to set a new standard by midnight Wednesday, said the limit would better protect public health, especially for children. They can inhale lead particles released from smelters, mines and waste incinerators and ingest it after it settles on surfaces.

Exposure to even low levels of lead early in life can affect learning, IQ and memory in children. Lead can cause cardiovascular, blood pressure and kidney problems in adults.
