Fossil fuels don’t just change the climate, they impact our children’s health

It was December 2009. The newly elected President Barack Obama was spending his first Christmas in the White House, the Black Eyed Peas’ “Boom Boom Pow” was at the top of the Billboard year end charts, and the iPhone 3GS was the new kid on the block. Meanwhile, the environmental community’s eyes were turned towards Copenhagen, where climate negotiators were working to try to craft a lasting international agreement on emissions. In the middle of the negotiations, Joel Pett published a comic in USA Today (reposted here), which has stuck in the minds of a lot of us who spend time thinking about environmental issues.

So when a recent scientific review by Dr. Frederica Perera at Columbia University came to the scientists on our team, we couldn’t help but remember the point Joel made with his poignant graphic back in 2009. Namely, that by reducing fossil fuel combustion we can not only reduce our impact on climate change, but that we can have cleaner air and healthier children. The review draws our attention to the unique effect that fossil fuel combustion has on children’s health, both by accelerating climate change and by increasing their exposure to air pollutants.

“Big data” comes to chemical testing – How to ensure more is better

Jonathan Choi is a chemicals policy fellow.

EDF Senior Scientist Dr. Jennifer McPartland contributed to this post.

The beginning of this century will no doubt be known for a lot of things. In the biological sciences, I predict it’ll be known for big data. It’s hard to wrap your head around just how far we’ve come already. For example, the data chips that sing “happy birthday” to your loved ones in those horrendously overpriced cards have more computing power than the Allies did in 1945. When I first started using computers, the 5.4” floppy disk was being replaced by the new 256Kb 3.5” disk. Now in Korea, you can get 1 GB per second internet speeds for $20 a month. That’s around 4000 floppy disks of data per second for about as much as I spend every week at the burrito place down the street.

In the biological sciences, we’ve seen an explosion of new ways to generate, collect, analyze, and store data. We’re photographing the world’s biodiversity and sharing it with crowdsourced taxonomists. We’re creating a database of the genomes of the world’s organisms. We’re mapping chemical exposures (our exposome), inventorying the microbes that live in our guts (our microbiome), ripping apart cells and sequencing every bit of messenger RNA that floats around inside (our transcriptome), and much more.

So, it’s not too surprising that regulatory agencies like EPA are pushing their own efforts to amass large quantities of data to help meet their missions. EPA has the unenviable task of reviewing tens of thousands of chemicals currently on the market with little health and safety data, on top of hundreds of new chemicals banging at its door each year. As we have written on numerous occasions, the agency clearly needs a better law that gives it greater authority to get the data it needs to effectively evaluate and manage chemical risks. But, given the information abyss in which we operate, we could definitely stand to adopt new testing approaches that generate at least screening level data on chemicals faster.   Read More »

What does BPA have to do with metabolism, mazes and my mom?

[CORRECTED 11-6-15:  Two statements in this post have been corrected as indicated below.]

Last week my mom called me out of the blue with a question on chemicals. You see, in my family, we make (and eat) a lot of kimchi—that spicy, wonderful, fermented cabbage that is ubiquitous in Korean cuisine. For my entire life, we’ve been using the same hard plastic containers to store and ferment kimchi in the basement fridge. My mom was calling me because those containers were getting pretty old and she wanted to replace them. She was wondering whether she should pay a bit more to buy kimchi containers that were explicitly labeled “BPA free.”
