This week, Open Phil launched the Lead Exposure Action Fund (LEAF) and became a founding partner of the Partnership for a Lead-Free Future (PLF). Given the interest around these initiatives, I thought an AMA might be a good way to share more.
At Open Phil, I’ve been fortunate to oversee our work on lead exposure with Santosh Harish and have been involved in some of the recent developments. I’ve particularly focused on helping get LEAF off the ground and contributing to the early stages of the PLF.
If you’re interested in learning more, here are a few useful resources:

A bit more about me:
I’ve been with Open Phil for about 2.5 years, after five years at GiveWell and a year with Giving What We Can. Currently, I lead our grantmaking in public health policy — covering areas like lead exposure, air quality, alcohol policy, and suicide prevention — as well as Global Aid Policy, and some work related to effective altruism (GHW). Before joining Open Phil, I worked across a variety of areas at GiveWell, from public health policy to charity evaluations, including methodological questions around moral weights and discount rates. I also contributed to GiveWell’s response to COVID-19.
I’m happy to answer any questions you have about lead exposure, our work at Open Phil, or anything else that catches your eye! I’ll be answering questions on Thursday afternoon, October 3rd Pacific Time (Edit: I answered some questions a bit early, but will check back)
Thanks Parth, I appreciate it and thank you for your support along the way!
IIRC, I first learned about it as a development issue from some very early work my colleague Andrew did at GiveWell. At the time, GiveWell wasn’t funding policy work, so it’d been deprioritized. But I’d got interested in public health policy from investigating this grant on pesticide suicide when I was at Giving What We Can, so I was pretty keen to dig into it.
But it was a pretty slow burn and I only got really excited about it between 2019 and 2021. Things I found particularly persuasive were this systematic review suggesting the median kid in an LMIC had elevated blood lead by US standards, Pure Earth telling me about Jenna Forsyth’s work in Bangladesh to remove lead from spices, and this comparative analysis highlighting its relative neglectedness, even compared to other hugely neglected issues like tobacco.
I’m not sure! When I first started talking to Pure Earth, they’d recently started to focus more narrowly on lead exposure, having previously worked across a bunch of different pollutants. They were also starting to explore focusing on more regulatory interventions when before they were mostly cleaning up individual toxic waste sites. It was pretty cool to see an organization really shifting and following the burden like that. Fwiw I haven’t reviewed the $1-$50 estimate, but I’m skeptical of the claim if it’s referring to remediating individual toxic waste sites (though so much is down to how many years of “speedup” to count that it’s hard to know without digging in).
Yeah, I think about this a lot. If we believe the GBD estimates, 6 million people died from lead exposure in the four years it took me to recommend substantial grants in the space. So even though that certainly wasn't the only bottleneck, it’s a source of personal angst.
The short (and probably unsatisfying) answer is I was working on a lot of other things. I think over the ~5 years I spent at GiveWell, ~25% of my time was on public health policy, and lead was only a fraction of that. With hindsight, I wish I’d advocated more effectively for GiveWell to put more capacity towards that work (though it’s also worth noting that a lot of the most compelling data points weren’t available until ~2020).
On LEEP specifically, we were pretty close to making a grant at GiveWell, but I’d got hung up on whether I believed the evidence for lead paint being a significant source of exposure (I still find that evidence tricky to interpret, but lead paint regulation has also been far more tractable than I expected such that I think it should be a priority anyway). When I moved to Open Phil in 2022, it was to launch the EA program on global health and wellbeing. We also agreed to transition the lead portfolio and other public health policy grants from GiveWell to Open Phil, but it took a bit of time for us to get to launching a program. I agree with Alexander’s assessment of our mistakes here. Fwiw this has all made me quite appreciative of other funders in the EA space who funded LEEP. I admire their work, and it's been fun working with Lucia and Clare (LEEP's co-EDs) in the build up to the launch.
