What is done with the contaminated soil/water once it is removed from the area? Where does it go?

This is a problem, combustion byproducts should be the primary thing they're looking for if they torched it... right?

Considering your experiences, Is there any government's inappropriate response to the disaster? what are the effective steps to deal with the accident?

Some non-urology (but medical still) questions. And you can combine the responses however you want.
- Is becoming a MD in America still a matter of meritocracy? Or do you think it favors students with connections and means?
I've seen many MDs who come from medical families and I feel they have a huge "advantage" over working class students when applying for med school.
-
Is getting the slots to the best residency / fellowship programs a matter of work performance or connections?
-
What's your opinion on America's research prowess on urology today?
-
What do you think of the direction America is headed in terms of medical access and costs of service? Should we remain optimistic?
-
What's the best way for patients to prepare for their first visit to a specialist? I've visited docs armed with a one - page summary of my medical history and purpose of my visit and many of them barely look at it.

Do you have a favorite Bollywood movie? :)

I believe sperm is less than 1% of ejaculate, most of the fluid comes from your prostate.

Can finasteride 1 mg per day cause any kind of damage in the long term?

As of right now, based on the data available, staying away from the spill site is the best option (how much outside of the range is really dependent on the level of concentrations detected near the spill site and wind direction). If you are near the spill site, make sure that the air around your house is monitored frequently (recommended continuous monitoring). If you are well outside of the spill site, there isn't much concern as long as you don't get near any down gradient surface water bodies.

We want know if there are continuing chemical releases, what they are, the ways people may be exposed - air, water, and in their homes - and how we can eliminate their exposures?

I wouldn't know if it hasn't been reported, I can only go off of what is publicly available since I am not involved with the current cleanup efforts.

Definitely would avoid any surface water bodies for a while until they have been cleared if they are connected to any streams near the spill site. As far as drinking water goes, if its from a municipal water supply, your local government will test for those chemicals typically anyways, they should post the results somewhere online. If you have well drinking water, take a sniff of the water and if you smell anything you may want to get it tested (you should have it tested regularly anyways). Just because you smell something doesn't mean it poses a risk to you in the short term. Our olfactory senses can detect concentrations of chemicals well below laboratory detection limits.

Environmental remediation typically adheres to risk standards based on adverse health effects observed in toxicological studies. These can range from immediately dangerous to life and health (IDLH), to burns, to difficulty breathing, and cancer risk factors. The symptoms people are encountering can be a mix of a few different things. Either they may be particularly sensitive (i.e. outside the standard deviations of the toxilogical study) or they may have had an acute exposure when the accident occurred. Current levels show that current exposure to air and groundwater is not a concern. I would say that surface water and soil near the site should be avoided.

The total VOCs they are measuring wouldn't capture dioxin concentrations in air, they would need to be evaluated separately. I haven't seen any dioxin measurements yet and I am not aware if they are measuring them at the moment.

So, I live less than 20 miles away from the center of East Palestine. When they did a 'controlled release' and the winds changed, hazmat guys were seen just down the street, and you could smell it in some parts of the city.
That said, how worried should I be when it comes to my tap/drinking water? What about my dog playing in the local ponds, or in Mill Creek?

Despite reassurances from officials that the area’s air and water quality is safe, residents in the vicinity of the derailment have reported multiple health symptoms, including nausea and burning sensation in their eyes. So whether it is safe for ppl to go back?

Oh got it for 624.1. Oh I see, yes I agree, the PQLs are much higher they could also be due to turbid samples requiring significant dilution. I cant imagine why they wouldn't be able to collect enough sample for surface water unless its a dry creek bed.

The second site has PQLs that are higher by a factor of 50x from the other two sites. I want to see the instruments they are using, see the procedures they are following, see results of quality control assessments. This looks very strange.

There were two major volcanic eruptions in 536 and 542 AD which led to a period known as the Late Antiquity Little Ice Age. It is suspected poorer diets from poorer harvests led to the Plague of Justinian wrecking havoc with a weakened population.
While there was a decline the Avars, Sassanid and Gupta civilisations, the vacuum led to the rise of Turks, Mongols and Islam. The strategy they have in common is that, at the time, the peoples lived nomadic lifestyles on the fringes of deserts. With the Sun being ‘feeble’, as Roman senator Cassiodrus puts it, these people could be more productive during the day.
