Chlorpyrifos: Mr. Pruitt, the science has been reviewed

Dear Mr. Pruitt, I hope you can help me out here. I’ve been having trouble explaining your recent decision in favor of the pesticide chlorpyrifos while dismissing years of work by EPA scientists to my environmental toxicology students. This is a chemical that interferes with the normal processes of the brain causing both acute toxicity – […]

Dear Scott Pruitt: Is this Atrazine’s DDT moment?

Dear Mr. Pruitt, I imagine there must be some angst these days about Atrazine.  With the 2016 EPA reevaluation concluding that the herbicide isn’t as safe as we all once thought, I am sure growers and consumers are anxious about which way the agency will swing: to ban or not to ban.  Admittedly, back in […]

Dear Mr. Pruitt: On this we can agree (I think.)

Dear Mr. Pruitt, With Trump’s proposed budget, looks like you could use some support. We disagree about climate change so I won’t go there, but you have said that cleanup of contaminated sites was a priority, and it looks like hundreds of millions of dollars for haz-waste cleanup could be axed. So, since I’ve been […]

Dear Mr. Pruitt, let’s talk about lead.

Dear Mr. Pruitt, Last week I wrote to you about DDT. This week let’s consider lead. Like DDT, another jaw-dropper for my environmental toxicology undergrads. You may not remember leaded gasoline. It was phasing out just as you were probably hitting the road. But I do, and I remember feeling good about asking for “unleaded” at […]

Urban landscapes, where even evolution is fast-paced

It is no surprise that we humans have a powerful effect on Nature. Not just the very large footprint we leave behind on the landscape, ocean life, and the atmosphere – but on life it self. As we increasingly become aware of how quickly at least some species can evolve in response to our heavy-handed […]

Make America Great Again?

Somewhere during the 2016 election night I read that voters wanted to turn back the clock to the days when they imagined our country was great. Greater than they consider it to be today; a 1950’s America. You know, the pre-Civil Rights America when a woman’s place was in the kitchen and the bedroom. The […]

GMO: The Times, They Are Misleading

The New York Times article, Doubts About the Promised Bounty of Genetically Modified Crops  rightly argues that herbicide resistant GMOs haven’t reduced the use of chemicals on the farm. But by equating genetic modification with herbicide resistant plants, this article is misleading. Many of us agree there are problems with herbicide resistant plants, and that […]
