“I think water low in minerals absorbs plastic from containers.”
By what mechanism?
- - - - - - -
The mechanism by which natural waters with minerals absorb minerals from rocks.
“Dozens of people spontaneously combust every year. It’s just not widely reported.”

Always of interest to myself.
First heard of same on old old TV show rerun: “Kolchak: The Night Stalker”.
Then found out it may have something to do with Hydrogen Sulphide Poisoning.
Now plastic ingestion?
Stranger and stranger, all the time.
Any new information appreciated.
Thank you. Norski
So you are “assuming” that plastics have similar properties as minerals?
Got it. Please leave the science to people that actually have some education in it.
Kolchak ran from 1971-72. Very few people drank from plastic water bottles in the era.
” . . .Then found out it may have something to do with Hydrogen Sulphide Poisoning. . .”
Hydrogen sulphide flammable as well.
Could also consider Flakka. First remove clothing and act insane while naked, attack LEOs with the strength of ten, and then cannibalize faces of victims.
Seems demonic enough.
#PureBlood here.
And while I will drink the occasional bottled water, mostly I drink water or tea from a stainless steel 20 oz Yeti.
That’s to keep stuff from growing in it. Bottled water is too thoroughly dead for that.
You can use your scroll wheel as well. It goes both ways.
I think anyone who pays extra for bottled water is loopy. The bottling companies use the same water source as found in the home. Plus, you don’t get to monitor how they prepare the bottles.
I suspect the same stuff is in the water you get from your tap. The bottling companies do not have separate water supplies.
Bad title of the article:
“Alarming Study Finds Most Bottled Water Is Full of Microplastics”
In truth what was found was
“Alarming Study Finds Most Bottled Water IN FRANCE Is Full of Microplastics”
I call BS. Pretty sure I’d notice eating a 5 millimeter piece of plastic.
Yes, but you’re the one emoting and overwrought by others choices. I hoped to spare you a fit of the vapors.
Microplastics (MP’s) as Contaminants
The term ‘microplastics’ commonly refers to plastic particles whose longest diameter is <5 mm and is the definition used by most authors. It has been suggested that the term microplastics be redefined as items <1 mm to include only particles in th emicrometer size range. The upper limit of 5 mm is generally accepted because this size is able to include a range of small particles that can be readily ingested by organisms (Freshwater Microplastics Emerging Environmental Contaminants. 2018, Springer International. Martin Wagner, Scott Lambert).
MPs have undoubtedly been present in the environment for many years (first reports of marine plastics in the 1970s and in freshwater systems in the early 2000’s), but they have not been extensively studied and are still an emerging concept. Plastics are polymers which generally decompose into smaller fragments. These fragments then further disintegrate into increasingly smaller fragments eventually forming nanoplastics.
Primary microplastics: Plastics directly released into the environment in the form of small particulates. They can be a voluntary addition to products such as scrubbing agents in toiletries and cosmetics (e.g. shower gels). They can also originate from the abrasion of large plastic objects during manufacturing, use or maintenance such as the erosion of tires when driving or of the abrasion of synthetic textiles during washing. MPs can be produced in the process of landfill and sewage treatment, construction, industrial activity, household laundry, and so on.
Secondary microplastics: microplastics originating from the degradation of larger plastic items into smaller plastic fragments through photodegradation (photo-, thermal, or bio-degradation) and other weathering processes (makes them brittle) of mismanaged waste such as discarded plastic bags. Plastic films used for crop production (used to conserve of moisture, reduce weed growth and increase soil temperature) are considered an important agricultural emission.
Due to the chemical makeup of plastic materials, receiving environments are potentially exposed to a mixture of microand nano-sized particles, leached additives, and subsequent degradation products, which will become bioavailable for a range of biota. The ingestion of MPs by aquatic organisms has been demonstrated, but the long-term effects of continuous exposures are less well understood.
Currently, there are in commerce more than 5,300 grades of synthetic polymers. Their heterogeneous physico-chemical properties will likely result in very heterogeneous fates and effects once they enter the biota. MPs may be taken up from the water column and sediment by a range of organisms.
This can occur directly through ingestion or dermal uptake most importantly through respiratory surfaces (gills). Experiments have shown that many zooplankton do not differentiate between polystyrene (PS) beads (2 and 6 μm) and algae when exposed to combinations of both. Studies then show evidence that a trophic transfer of MP’s occurs for
instance, from mussels to crabs.
Effects of Leaching Chemicals
How quickly impurities, polymerization byproducts, breakdown products, catalysts, solvents, and additives leaching from plastic materials are not easy to assess but mass spectrometers can find volatile, semi-volatile, and non-volatile substances that have been leeched into water during environmental monitoring studies.
Biological Effects of Sub-micrometer Plastics
MPs can be taken up and ingested by aquatic and terrestrial organisms, which can transfer as food into humans, and may pose latent health risks. Studies on lower animals have shown that gills, gut, liver, and brain are all target organs in fish, as well as a range of toxic effects including oxidative stress, cellular pathologies consistent with tumor formation in the liver, some organ specific ionoregulatory disturbances, and vascular injury (Microplastics in Terrestrial Environments. Emerging Contaminants and Major Challenges. Springer International. 2020).
Yes… You would’ve spared me the evidence of seeing that our country is now inhabited by a bunch of pussies are afraid of their own shadows. I appreciate your consideration.
I thought plastic was forever. Not bio-degradable
If you dissolve salt in water, you can’t see it.
By the way- apologize for being uncivil about this. While I feel the root of this issue IS important and is a devastating cancer on our society (embodied by the masking and vaccination mandates for “safety” and seeing sheep compliantly masking and distancing) it isn’t really worth drilling down on it in a thread like this.
So I am sorry about that.
I think is critically important and seems to get zero discussion, but in this context, it is for people to make their own choices as they should. I wasn’t trying to throw water on the thread.
Even more surprising, 94% of water samples from the United States contained microplastics, which topped the list.
