Ferns absorb arsenic through their roots and store it in their leaves, which can then be cut off. Arsenic -- once used to treat wood -- can still lurk in old roofs, decks, and playgrounds." 09-08 A Vacuum Alternative to Pesticides (Science Daily) "A physical chemist has developed a new technique for ridding harvested produce of insect pests and microorganisms without using pesticides such as methyl bromide. The technique, called Metabolic Stress Disinfection and Disinfestation, suffocates pests by exposing them to cycles of vacuum and pressurized carbon dioxide. Treatment chambers could be easy to develop on a large enough scale for farmers to use." 09-08 Sludge Used to Combat Lead Toxins (Time.com) "Scientists using federal grants spread fertilizer made from human and industrial wastes on yards in poor, black neighborhoods to test whether it might protect children from lead poisoning in the soil.
