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.
Clues from the fossil record give us information about what species went extinct and when, but how the extinction happened in the first place has been a puzzling question for scientists. One of the biggest theories involves a series of volcanic eruptions, which took place about 250 million years ago in Siberia. According to Smithsonian's Mass Extinction, these eruptions spewed enough lava to bury the continental US under a layer 1,000 feet deep. Wikimedia Commons Part of the Siberian traps.
