Around here the biggest issue is duck hunting, where the pellets almost certainly wind up directly in a wetland.

I take about 20g daily of psyllium husk, i'm worried about lead. Any advice?

Check for reviews that test for lead levels and buy products with low lead. For example, ConsumerLab is one subscription website that does this testing, but there are many others.

What about lead tape for golf? My putter has a strip of it on the sole. I don’t lick it or anything but is it shedding contaminants constantly?

Yes, it's depositing some lead on surfaces it contacts, including likely the grass on the green. That said, if the tape isn't wearing away and requiring regular replacement, the amounts likely are trivial. A quick search suggests that lead-free alternatives such as Tungsten-based weight tape are becoming available.

There's a weird trend on here of karma chasers playing "gotcha" by posting rebuttals to things that literally nobody is claiming and hoping that we don't notice. It's fucking pathetic man. What would it take for you to reevaluate your life.

Lead-free solder works fine as long your soldering iron is decent. Even if the lead isn't vaporized, you'll be exposed by touch and splatter. When I learned to solder I learned on complete crap soldering irons that could barely work with leaded solder, and I developed a prejudice against lead-free. But lead-free solder has gotten better, and investing in a Weller or a Hakko will save the hobbyist so much time and fru…

Damn right, there's absolutely no justifiable reason for using leaded solder for hobby projects today. Get a good iron, and a nice roll of SAC305 from a reputable vendor and you won't have any issues.

Does modern lead-free soldering still end up having tin whiskers? That was always the big downside as far as I was concerned. A quick internet search implies it's still a thing.

Did you know, the world still mines more lead now than it did 50 years ago, at the peak of 'put lead in everything' mania? To me, this says that we still put lead in too many things. Lead is still used for flashing in roofs. It's still used as a mould release when making plastics. It's still used in making dishware. It's still used in bullets. It's still used for all kinds of things which will one day end up in the e…

I didn’t know about the flashing. Lots of people use rail barrels that fill from a downspout to water their gardens. I wonder what kind of lead exposure that could create.

Isn't that implied by the context? Lead is fantastically bad for human health and it's worth the cons to use Li batteries to avoid pulling lead out of the earth and into the chain of human contaminants .

My point is that lead for batteries is aggressively recycled while lithium is almost exclusively pulled from primary extraction and rarely recycled. > Despite the smaller supply of lithium, a study earlier this year in the Journal of the Indian Institute of Science found that less than 1 percent of Lithium-ion batteries get recycled in the US and EU compared to 99 percent of lead-acid batteries, which are most often…

That's a fine stance, of course. But you asked "why". The posters above are focused on human health as a concern, over the environmental impact you're focusing on. Just different perspective.

https://www.cbsnews.com/news/milwaukee-schools-lead-poisonin... This aged wildly poorly.

Better link? https://www.cbsnews.com/news/rfk-jr-hhs-layoffs-cdc-lead-poi... TL;DR: RFK has cut health programs including the division that deals with lead poisoning. The first link is about that choice's fallout on school children exposed to lead. Yay blanket federal cuts.

Can you imagine a world where two things could be true at the same time: RFK cares about environmental toxins, and RFK cut a department that was meant to deal with lead posioning?

I don't know if this was something he pushed for, but let's assume it was. Could there still be a reasonable cause to cut that department?

A lot of people assume if you oppose the Do Good Things act, that you must be a bad person. Was this department getting results? It was spending roughly 750k per full time employee per year (based on the 150M for 200 full timers from the article). Was it working? It could have been, it also could not have been.

Maybe this was an actually bad decision made by an actually bad man. But previous coverage of him has taught me to take anything reported about him with a very large grain of salt.

All over. There are multiple indoor ranges in almost every state.

It’s hard to have an outdoor gun range in an urban environment!
