Weed killer impacts frog’s sexual development

Canadian researchers find evidence of feminization


 

Atrazine, a widely used weedkiller, affects the sexual development of frogs, according to a team at the University of Ottawa who found that, at low levels comparable to those measured in the environment, fewer tadpoles reached the froglet stage. What’s more, the ratio of females to males went up. “Atrazine is one of the top-selling herbicides used worldwide and was designed to inhibit weed growth in cornfields,” the university said in a statement, Reuters reports. “It is so widely used that it can be detected in many rivers, streams and in some water supplies. This has raised the alarm on the possibility of other serious detrimental environmental effects.” But Syngenta AG, the Swiss manufacturer behind atrazine, has defended it, saying it’s one of the best-studied herbicides available. Some studies have tied it to low birth weight, birth defects and premature babies.

  1. Will it affect my tadpoles? That's the next question I'd like answered.

  2. "Some studies have tied it to low birth weight, birth defects and premature babies."

    Nothing to worry about, there.

    • "But Syngenta AG, the Swiss manufacturer behind atrazine, has defended it, saying it's one of the best-studied herbicides available."

      Nice bafflegab – you notice they don't say anything about the results of the studies.

  3. the header is suggesting the comparison here is meant for the sentient human race….as far as i can tell no one on the face of the earth resembles a frog…… there might be frog people though!
