  • Public-health managers can test phosphorus levels in waters across various Gulf locations," Drs. Rance Hardison, co-author on the paper, said, "and know that low levels could indicate highly toxic red tide blooms. (planetsave.com)
  • The US organic industry has approved over 3000 toxic pesticides for use in organic farming, many of which are neurotoxins or with a toxic profile requiring "Danger" labels. (risk-monger.com)

  • It's time to tell the FDA to focus on the real issues, like toxic elements in our food supply - not health-promoting supplements that have improved lives and boosted immune systems. (federaljack.com)
  • The only difference between organic pesticides and those used in conventional farming is that organic toxins are rarely tested for health and environmental safety and there is no testing for toxic residue levels on organic produce . (risk-monger.com)
  • Toxicological examinations have shown the levels of pesticides and chemicals found even in the fish that has been withdrawn from the market are so small that an adult would have to eat between 3.4 and 166 kg of pangasius each day before they could even begin to be considered toxic. (wur.nl)
  • To explain the findings, researchers calculated the maximum amount of pangasius considered safe to eat, on the basis of the highest levels of the toxic contaminants ever discovered in pangasius. (wur.nl)
  • Now we understand the biological mechanism behind some of the varied toxic levels seen in Gulf algal cells," Damian Shea, an NC State professor of biology and environmental toxicology, said. (planetsave.com)
  • Research has found that Atlantic killifish has adapted to lethal levels of toxic pollution due to its genetic diversity. (i4u.com)
  • So while lobbyists for the organic industry continue to push the big lie and expand their market through fear campaigns (deep down, I'm sure they must be morally exhausted from carrying around such a heavy yolk of hypocrisy), I decided to focus on a group of toxic pesticides approved for organic farming.
