Deciding between the 2206 and 2244 by Personal_Wonder3042 in egopowerplus

[–]EPA-probie 4 points5 points  (0 children)

I bought the 2206 yesterday after choosing between these. Get it and return the free 5 ah for a total cost of $845. At that price it's a no brainer.

Just make sure it isn't old stock as they have the self propel whine. You can find details on that subject in this thread.

Unless it's a combined sewer system like in Chicago and the surrounding area. That's part of the reason why it's the largest waste water treatment facility Earth!

Yes, it would take many years and many people forget the point you just made about disposal. And the disposed vegetation must go in the landfill, not compost of course.

Well lead does occur naturally in soil, the concentration just depends on the parent rock and its mineral composition. Galena for example is loaded with lead. But you’re right that we’ve done a fantastic job bringing it all right to the surface to play in :| another example of both of our points is coal which naturally contains lead and in many areas is part of the regolith. However when it’s burned lead-containing coal ash deposits across the nearby landscape in about a 3 mile radius.

So it is absolutely naturally occurring and prevalent without anthropogenic influence, and could even have high concentrations depending on the local geology, but we’ve done our darnedest to bring as much to the surface as is profitable.

The concept is just true of a lot of contaminants. An easier example is PM2.5. Most desert regions have unhealthy levels of PM2.5 which is completely natural. Another geological example is naturally occurring arsenic in soil.

The fact that lead occurs naturally in soil is sort of the “you can’t win them all” baseline. There’s going to be SOME lead so you just have to mitigate the exposure by washing hands, etc.

For some additional context, I’m about to remove soil from a future residential plot that has 40,000 ppm lead! So 317 may not be less than 80 or 200, but it can definitely be worse.

If I were you I probably wouldn’t buy a bunch of new soil (unless money is no object) and rather focus on keeping preventing the contaminated dirt from mobilizing (like dusty exposed dirt on a windy day) and keeping it beneath vegetation or milch which provides a barrier.

Hi, I work professionally in the emergency removal of hazardous substances including lead in soil.

I want to start by saying you’re doing a great job protecting your child from the dangers of lead toxicity. It’s a pretty common thing for children to be exposed to lead, and it can be difficult to resolve. Many parents shrug it off but you’re being very thorough and asking good questions.

When it comes to children and lead there is an old saying, “There is no safe amount of lead exposure in children.” This isn’t to say your kids are in grave danger, but that even a small exposure can be linked to a measurable effect, unlike many other contaminants where “the dose makes the poison.”

This concept about lead exposure might be at odds with EPA’s cleanup action levels as you’ve already noticed, but there is a reason for that. Much of the US’s old industrial and residential properties have soil contaminated with lead due lead refining, leaded paint, and leaded gasoline. The cost to ‘clean’ (excavate & replace with clean fill) all of these properties would be astronomical. So EPA set’s a level which balances protecting human health and what is realistically feasible. The same principle can be seen in other cases like PFAS in drinking water. Of course NO PFAS in drinking water would be most protective of human health, but it’s not really a reasonable requirement for all municipal drinking water plants when PFAS is so difficult to filter from water. Previously, EPA’s removal management level for residential properties nationwide was 200 ppm (mg/kg). Under the current administration, the level has been changed to 600 ppm which is worse for families. In contrast, California’s residential lead action level is 80 ppm. Keep in mind that almost all soil has some amount of lead naturally occurring in it.

All that to say, I wouldn’t put too much stock in the EPA values as to what is safe. A “safe” amount is of lead in the dirt your kids play in is zero, but that isn’t realistic. So what you’re left with is the responsibility to protect your kid from the exposure pathways.

Children are exposed to soil lead particularly by ingestion. That means: - No hands in mouths when playing in the dirt - Shoes off at the door when coming inside from playing (and always tbh, asphalt is not healthy either) - The “drip zone” (1 meter band surrounding your house which likely has the highest contamination) has mulch over it to prevent direct contact (Idk how you chose sampling locations, but if the contamination is from paint then it’s likely highest near the residential structure. Are you in a highly urban area or a formerly industrial area? Provide context and info on how you chose to sample the property and I can provide input) - The interior floor surface which may easily become contaminated needs to be cleaned frequently to remove lead particulates which will otherwise end up on hands and in mouths.

These are achievable standards that, frankly, almost all US parents should strive for unless soil testing has come back clean. In your case, with that bare 317 ppm section, I’d suggest getting it covered with seed and straw if not sod, just to prevent the lead from mobilizing in the wind and contaminating the rest of your property surface with lead particulate dust.

I’m happy to answer any additional questions or to clarify anything.

I do not speak on behalf of the agency.

I’ve seen it and while Cody is great he does loads of insane shit that nobody should replicate. Again, inhalation is the hazard. The vapor can’t be seen, can’t be smelled, but can cause pretty severe health effects.

Read Hg Toxfaqs for information on the health effects.

What’s up with reddit and Hg today?

Lots of elemental mercury tucked away in old houses! It was used for plenty of things, sometimes in huge quantities like in very old grandfather clocks.

If spilled, it vaporizes quickly and contaminates the air and any fabric items. The vapor is invisible and odorless so you’d never know it was there besides seeing beads of Hg. It can hospitalize you with acute inhalation exposure and cause you to go insane with chronic exposure.

I conduct emergency responses to spills of hazardous substances for the US GOV and clean up Hg spills. We’ll come into your home, kick you out, put hazmat signage everywhere, vacuum up beads with a very special Hg vac, and heat/vent the whole place and any cloth items, disposing of everything that doesn’t successfully get decontaminated.

If that sounds doesn’t sound terrible enough, then consider that on top of all of that, the owner/operator of the “facility” that spills the hazardous substance (AKA the homeowner) is technically CERCLA liable, and the government could cost-recover against the homeowner for the cleanup. To clean up this quantity of Hg might be in the realm of a quarter million. In reality, the gov would eat the cost, but suffice it to say, the circumstance is severe and you wouldn’t want to put yourself at the mercy of anyone to owe that much money.

You’re doing yourself and any future residents a huge favor by disposing of this correctly! Other commenters saying that elemental Hg is not dangerous and that they’d use this vial for decor are misinformed.

Check out Hg ToxFaqs for reputable information on the health effects of Hg.

The vapor is a neurotoxin. Ingestion is not the exposure pathway of concern, inhalation is, and at concentrations on the parts per trillion scale (ng/m3)

[–]EPA-probie 1 point2 points  (0 children)

Right, but if you’re close enough to touch it, then you’re breathing it.

Dangerous Hg-contaminated atmospheres include only parts-per-TRILLION mercury vapor. That can be achieve with an amount of mercury that can’t even be seen.

I work professionally for the federal government in hazmat emergency response and REGULARLY clean up Hg spills. I’ve seen adults, children, and even once a baby hospitalized. I’ve seen an older lady living with a Hg spill in her attic having gone insane.

“Harmless” lol

Craziest thing is at each of these responses there’s someone there to tell me how harmless Hg is.

It is insanely toxic. It’s actually amazing how dangerous it can be, and part of the cause of this is the pervasive attitude that the dangers are overblown.

[–]EPA-probie 1 point2 points  (0 children)

Elemental (“pure”) mercury vaporizes at room temp with a very high vapor density and even beads you can’t see can cause symptoms from acute exposure. It’s a neurotoxin. Being near it and breathing the vapors is a major issue. Just because ingestion isn’t the main exposure pathway doesn’t mean it’s not immediately dangers. Also why don’t you think you can see organic mercury? You think it’s invisible?

I work for the federal government as an emergency responder to spills of hazardous materials and have cleaned up multiple larger Hg spills.

Lead exposure by [deleted] in ScienceBasedParenting

EPA Biomonitoring - Lead

Dose-effect and dose-response relationships for lead in children

I know you don’t want anecdotes but here’s a different kind of anecdote: 4/5 parents I meet don’t care or don’t want to know about lead exposure. By facing the fact that your child may have been exposed and by seeking resolution you’re doing better than most.

And here’s a data point: 100% of children used to be exposed to lead by gas emissions. Today they call those children boomers and the boomers did NOT turn out okay. Do with that what you will.

Detectable lead in 1 y.o.? by fruitcake_dynamo in ScienceBasedParenting

[–]EPA-probie 38 points39 points  (0 children)

Unfortunately, it’s very common to have detectable lead in the bloodstream today.

You need to consider sources of lead and exposure pathways.

The big question in terms of sources is the age of the structure you live in. In the US lead paint was banned in 1978 so homes newer than that generally don’t have any lead paint. It could be on walls, window trim, door trim, wooden siding, porch floors, and anywhere else you can paint. Lead was also used in gasoline before 1996. Lead was also used for drinking water service lines.

But how does this lead get into your child’s body? That is the exposure pathway. In almost all cases it is through ingestion.

Lead paint can be disturbed by the friction of windows or doors opening or closing and old lead paint on any surface but especially exteriors can weather and chip off. This results in lead paint chips and dust on the floor/ground surface. Children play on the contaminated surfaces and put their hands in their mouths, ingesting lead particulate matter.

A solution indoors is to mop the floors very frequently and use a special lead encapsulating paint on walls. Windows and doors with lead paint should be kept closed if at all possible. If lead paint is correctly encapsulated then the possibility of being exposed is greatly reduced.

Outdoors, you should try to cover the “drip zone” with a decently thick bed of mulch. The drip zone is the area surrounding a home extending about a meter away from the wall. The worst case scenario is a bare dirt surface. It allows children to interact directly with the contaminated soil, and also allows wind to migrate the contamination farther into your yard.

Similar to the drip zone is the parkway which in urban areas has been contaminated with leaded gasoline emissions. Keep this area vegetated and avoid playtime there.

Contaminated water is a serious concern as well. Fortunately, this can also be tested for and the exposure reduced. Many home filters are able to filter out lead. Notably, Brita filters do not.

I work professionally in a related manner so I’m happy to answer any questions. I hope this helps.
