Lead in paint and the health hazard posed by exposure through inhaling or swallowing lead-based paint prompted Congress to pass a federal lead based paint disclosure form requirement in 1996, called the Residential Lead-Based Paint Disclosure Program, or Title X.hat Lead-Based Paint Disclosure Laws Require. 1  Under federal EPA and lead disclosure rules, a lessor or seller of private or public housing built after 1977 must use a lead paint disclosure form to disclose any known information concerning lead-based paint or lead-based paint dangers or hazards.
The Permian-Triassic extinction The largest of the Big Five was the end-Permian or Permian-Triassic extinction event roughly 250 million years ago, which eliminated as much as 95 percent of the planet's species. Before this extinction, marine animals were mostly filter feeders stuck in place on the seafloor, such as crinoids or sea lilies.
The K-T extinction was not the first such massive die-off in history, nor was it the largest. The Permian-Triassic extinction event, known as the Great Dying, occurred 251.4 million years ago and eradicated 96 percent of all marine species and 70 percent of all terrestrial vertebrates species on earth.
