Science / Re: "Just One Word: Microplast...
Last post by Recusant - December 01, 2024, 06:55:44 PMI've missed posting a few items on this beat the past few months--none of them particularly encouraging. This one may at least be helpful. Cutting to the chase: boil it then filter it--even just boiling it can help.

"There's a Surprisingly Easy Way to Remove Microplastics From Drinking Water" | Science Alert
QuoteTiny fragments of microplastics are making their way deep inside our bodies in concerning quantities, significantly through our food and drink.
Scientists have recently found a simple and effective means of removing them from water.
A team from Guangzhou Medical University and Jinan University in China ran tests on both soft water and hard tap water (which is richer in minerals).
"Tap water nano/microplastics (NMPs) escaping from centralized water treatment systems are of increasing global concern, because they pose potential health risk to humans via water consumption," write the researchers in their paper, published in February.
They added in nanoplastics and microplastics before boiling the liquid and then filtering out any precipitates.
In some cases, up to 90 percent of the NMPs were removed by the boiling and filtering process, though the effectiveness varied based on the type of water.
Of course the big benefit is that most people can do it using what they already have in their kitchen.
"This simple boiling water strategy can 'decontaminate' NMPs from household tap water and has the potential for harmlessly alleviating human intake of NMPs through water consumption," write biomedical engineer Zimin Yu from Guangzhou Medical University and colleagues.

QuoteAbstract:
Tap water nano/microplastics (NMPs) escaping from centralized water treatment systems are of increasing global concern, because they pose potential health risk to humans via water consumption. Drinking boiled water, an ancient tradition in some Asian countries, is supposedly beneficial for human health, as boiling can remove some chemicals and most biological substances. However, it remains unclear whether boiling is effective in removing NMPs in tap water.
Herein we present evidence that polystyrene, polyethylene, and polypropylene NMPs can coprecipitate with calcium carbonate (CaCO3) incrustants in tap water upon boiling. Boiling hard water (>120 mg L–1 of CaCO3) can remove at least 80% of polystyrene, polyethylene, and polypropylene NMPs size between 0.1 and 150 μm. Elevated temperatures promote CaCO3 nucleation on NMPs, resulting in the encapsulation and aggregation of NMPs within CaCO3 incrustants. This simple boiling-water strategy can "decontaminate" NMPs from household tap water and has the potential for harmlessly alleviating human intake of NMPs through water consumption.

Only the first hurdle in making it law.
The House of Lords will obstruct it.
Biggest problem is coercion.
Son: "Look Mom, you'll be better off dead."
Daughter: "No."
We should all be taught there is nothing in life that cannot be taken away, and what goes around comes around.

Last post by Tank - November 30, 2024, 09:33:51 AMWhat was impressive is that this is an apolitical 'bill'. That is to say there is no party line to follow. It is a free vote. Listening to the 5 hours of public debate in parliament was basically quite refreshing. Strong views deeply held dealt with respect. I'd forgotten politics could be done this well.

It still has some way to go and may be modified in the process.

Last post by Icarus - November 30, 2024, 01:20:43 AMYes that is the one Recusant. For some reason that kind of stuff grabs my interest. Certainly not in the same league as the eceptional work that DL has done.

We have made a mistake while in the process of selecting our national leader. The degree of seriousness of the the mistake is yet to be determined. More than a few of us have come to believe that we have fucked ourselves..Royally!
It is of only small comfort that the Leapord will not eat MY face. The voters choice will almost surely lead to more inflation which will affect my own budget unfavorably. I will manage somehow. The less fortunate, which is something like 50% of the entire population, will fall onto harder times than ever. They are the ones who live paycheck to paycheck. Not because they are lazy or unworthy but because that is an economic situation in which they cannot escape. The sadist part of that scenario is that the disadvantaged will probably blame their plight on Biden or Obama or Harris. (SIGH)

Last post by Dark Lightning - November 30, 2024, 01:11:48 AMI need to formalize my requirements in the case that I'm left quadriplegic or incapacitated in some way where I can't make my wishes clear. In either of those cases, I want no nutrition nor even an IV. My wife's mother laid in a bed for almost 2 years after a stroke. Managed to eat, though. It's a complete waste of resources that I have no interest in using...just to end up dead at the end, anyway.
