A new study finds you can reduce the amount of microplastics you drink simply by boiling your water.
Scientists are just beginning to understand the health risks associated with microplastic exposure.
Nano- and microplastics are bits of plastic as tiny as one-thousandth of a millimeter in diameter.
Boiling and filtering your tap water may dramatically lower the amount of microplastics you drink, according to new research.
Recent studies have found that nano- and microplastics (NMPs), which are bits of plastic as tiny as one-thousandth of a millimeter in diameter, have been found in a host of products and even in tap water.
A new study, published February 28 in Environmental Science & Technology Letters, found that boiling mineral-rich water for just five minutes can reduce the amount of NMP you’re exposed to by up to 90%.
Scientists are just beginning to understand the health risks associated with microplastic exposureTrusted Source, but growing evidenceTrusted Source suggests the plastics can accumulate in the body and trigger oxidative stress, inflammation, insulin resistance, and liver issues.
Certain advanced water filtration systems can capture and help remove some NMPs from tap water. But researchers wanted to figure out other options to remove microplastics, especially since in poorer countries cheaper, more accessible solutions for clean water are needed.
Boiling water may be a safe, simple solution that can effectively decontaminate household tap water, the new findings suggest.
“Boiling water before drinking is a great example of an ancient cultural practice that can help reduce an environmental exposure,” Dr. Luz Claudio, PhD, a professor of environmental medicine and public health at the Icahn School of Medicine at Mount Sinai, told Healthline.
Claudio was not involved in the study.
How boiling water can help remove microplastics
The researchers found simply boiling water is the first step to removing NMPs from tap water.
The researchers collected multiple samples of tap water from Guangzhou, China and contaminated the samples with varying levels of NMPs.
Each sample was boiled for five minutes then left to cool for 10 minutes.
Boiling hard water that’s rich with minerals — such as calcium or magnesium — creates a chalk-like residue known as limescale, or calcium carbonate (CaCO3), which can trap the plastics.
That solid, chalky residue then had to be separated and removed from the water with a standard coffee filter or stainless steel filter, thereby removing NMPs.
The team found that the impact was greatest in harder water: In samples that had 300 milligrams of CaCO3, for example, nearly 90% of NMPs were removed.
In softer water samples with less than 60 mg of CaCO3, roughly 25% of NMPs were removed.
“What’s important to note here is that the effectiveness of trapping these micro/nano plastics in these mineral solids is tied to how hard the water is – the harder the water, the more solids are formed, the more microplastics are trapped,” Dr. Anja Brandon, PhD, the associate director of U.S. plastics policy at Ocean Conservancy and an environmental engineer, told Healthline.
Brandon was not involved in the study...
How to limit your exposure to microplastics 
Anyone who wishes to boil their water should do so in a glass or stainless steel pot.
After boiling the water for about five minutes, let it cool, and do not stir it, Claudio says.
The microplastics need to bind to the calcium and fall to the bottom of the pot so they can filtered or scooped out."

Water Pollution - Effects and Causes
Water pollution has become a pressing problem all over the globe. In the previous blog, we had a look at the major water pollutants. In this blog, let me walk you through the effects and causes of water pollution. All water bodies have an innate ability to cleanse themselves. They can easily handle small volumes of pollutants and degrade them with the help of dissolved oxygen and the microbial…

putting my prediction on record now that the coming decade is going to see the rise of viral-marketed fancy at-home water filtration systems, driving and driven by a drastic reduction in the quality of U.S. tap water (given that we are in a 'replacement era' where our current infrastructure is reaching the end of its lifespan--but isn't being replaced). also guessing that by the 2030s access to drinkable tap water will be a mainstream class issue, with low-income & unstably housed people increasingly forced to rely on expensive bottled water when they can't afford the up-front cost of at-home filtration--and with this being portrayed in media as a "moral failing" and short-sighted "choice," rather than a basic failure of our political & economic systems. really hope i'm just being alarmist, but plenty of this already happens in other countries, and the U.S. is in a state of decline, so. here's praying this post ages into irrelevance. timestamped April 2023
#apollo don't fucking touch this one#serious post#not a shitpost#hope i forget about this post and have no reason to ever look back on it one day#fyi i'm aware that access to potable water is already a major issue in parts of the U.S. yes i know flint michigan exists#i'm saying that this issue is going to GROW unless local & federal governments work together to fix it.#so it's a matter of if we trust them to fix it. And well--do you?#what are the chances the government just denies there's a problem until the water actually turns brown#at which point it's already been common knowledge for years and people have just become resigned and that's our new normal#i'm mean come on. how many of us already believe that we're being exposed to dangerous pollutants we don't know about and can't avoid#like that's pretty much just part of being a modern consumer. accepting that companies will happily endanger your life for a few pennies#and the most you'll get is like a $50 gift card as part of a class action rebate 20 years down the line#probably the history books will look back on Flint as a warning and a harbinger that went ignored#luxury condos will advertise their built-in top-of-the-line filtration systems--live here and you can drink water straight from your tap!#watch the elite professional class putting $700 dyson water filtration systems on their wedding registry#while the rest of us figure out how to fit water delivery into our grocery budget while putting 90% of our paycheck towards rent#also eggs are $15

Living machines are essentially intensive, indoor artificial wetlands. Technical names for living machines include "advanced ecologically engineered systems" and "fixed-film ecology wastewater treatment systems." What they entail is mimicking natural processes of biological decomposition in a constructed aquatic environment. Simply put: dirty water goes in, passes through a series of self-contained aquatic ecosystems, and clean water comes out. The water is, in fact, so clean that it can be safely discharged into sensitive aquatic environments, like natural wetlands. And it does all of this without any of the usual chemical treatments or high-energy inputs of conventional wastewater treatment. Living machines produce such safe effluent because they achieve what is known as "tertiary treatment," meaning they successfully abate pollutants. How does a biological system do this? Simple: it uses them as inputs. Let me explain. The most common such pollutants are nitrogen and phosphorous. These happen to be the two nutrients whose out-of-whack flows have pushed us past a key planetary boundary. The biggest reason for this is industrial agriculture: it relies on synthetic nitrogen and mined phosphorous to exceed the carrying capacity of the ecosystems in which it operates. One of the big problems with industrial agriculture is that a great deal of the nitrogen and phosphorous applied isn't actually utilized by the food being produced: most of it runs off into waterways. This leads to far-reaching, ecologically catastrophic events ("eutrophication"). By constructing a complete food chain within the living machine, each step creates the food for the next step. Excess nutrients, like nitrogen and phosphorous, feed microorganisms which are then consumed by larger creatures and so on up the food chain, until we are left with harmless components and a great deal of life. The living machine converts pollution into biodiversity and clean water, instead of run-off and eutrophication. It's a prime example of true "regeneration."

Per- and polyfluoroalkyl chemicals, known commonly as PFAS, could take over 40 years to flush out of contaminated groundwater in North Carolina's Cumberland and Bladen counties, according to a new study from North Carolina State University. The study used a novel combination of data on PFAS, groundwater age-dating tracers, and groundwater flux to forecast PFAS concentrations in groundwater discharging to tributaries of the Cape Fear River in North Carolina. The research is published in the journal Environmental Science & Technology. The researchers sampled groundwater in two different watersheds adjacent to the Fayetteville Works fluorochemical plant in Bladen County.

Subspace doodles (PHIGHTING! Mermaid au)
Tumblr media Tumblr media
so I was thinking more about the PHIGHTING mermaid au I’m doing and. What if subspaces’ gas- instead of being like actual gas, was polluted oil? I think that could make for a really cool trope if I ever were to redesign him for it :3!
For the design notes in specific:
When out of control, his “gas” takes the form of polluted oil, in control (as in wearing his mask and tank) it gets filtered into something akin to toxic brine (in which long exposure to can cause a lot of issues, specifically different types of shock, breathing issues, etc). Although the brine isn’t too dangerous to be around in small amounts, it can be harmful over time.
for those wondering what ACTUAL brine water (or more specifically brine pools) are, it’s pretty much a large accumulation of highly concentrated saltwater (which usually is around 10 times saltier then the ocean surrounding it) For most sea animals this brine means instant death due to the fact that is has no oxygen in it as well as the high saline levels.

The company behind the Coastal GasLink gas pipeline project in northern B.C. has received a whopping $346,000-fine from the B.C. government for environmental deficiencies and providing false and misleading information.
According to the Ministry of Environment, Coastal GasLink Pipeline Ltd. failed to meet conditions of its environmental assessment certificate. In a Thursday statement, it said compliance officers found inadequate erosion and sediment control during several inspections along the pipeline route in April and May last year.
The company also gave false and misleading information last October as well in relation to maintenance inspection records, the province found. That cost Coastal GasLink $6,000, while the erosion control matter cost $340,000.
“As a result of continued concerns, the Environmental Assessment Office has prioritized the CGL project for compliance monitoring, with nearly 100 inspections by air and ground since the project started in 2019,” B.C.’s statement reads.
“These inspections have led to the EAO issuing 59 warnings, 30 orders – including 13 stop-work orders – and more than $800,000 in fines.” [...]

3D Maps Reveal a Lead-Laced Ocean
About 1000 meters down in a remote part of the Atlantic Ocean sits an unusual legacy of humanity’s love affair with the automobile. It’s a huge mass of seawater infused with traces of the toxic metal lead, a pollutant once widely emitted by cars burning leaded gasoline.

"Legislative momentum against PFAS has surged this year, as at least 11 states enacted laws to restrict the use of “forever chemicals” in everyday consumer products or professional firefighting foam.
The legislation includes bans on PFAS in apparel, cleaning products, cookware, and cosmetic and menstrual products. Meanwhile, lawmakers in some states also passed measures that require industries to pay for testing or cleanup; order companies to disclose the use of PFAS in their products; and mandate or encourage the development of PFAS alternatives, according to Safer States, an alliance of environmental health groups focused on toxic chemicals.
In total this year, at least 16 states adopted 22 PFAS-related measures, according to the group. Since 2007, 30 states have approved 155 PFAS policies, the vast majority of them in the past five years.
The thousands of chemicals categorized as perfluoroalkyl and polyfluoroalkyl substances, or PFAS, do not naturally break down and are found in the blood of 97% of Americans. Some PFAS compounds can harm the immune system, increase cancer risks and decrease fertility...
Earlier this year, the U.S. Environmental Protection Agency released new standards limiting PFAS in drinking water. Water systems have five years to comply with the rules. Even before the EPA action, 11 states had set their own limits on PFAS in drinking water, starting with New Jersey in 2018.
Water utilities and chemical manufacturers are challenging the new EPA standards. But states also are heading to the courthouse: So far, 30 states have sued PFAS manufacturers or key users for contaminating water supplies and other natural resources, according to Safer States...
Sarah Doll, national director of Safer States, said one reason states have been so successful in enacting PFAS limits is that more companies are willing to stop using the chemicals.
“When California restricted PFAS in textiles, all of a sudden you saw companies like REI saying, ‘We can, we’re going to do that. We’re going to move to alternatives,’” Doll said.
In Vermont, state lawmakers in April unanimously approved a measure banning the manufacture and sale of PFAS in cosmetics, menstrual products, incontinence products, artificial turf, textiles and cookware.
“The same as everyone else, like Democrats, we want to make sure that we remove PFAS and get it out of products as soon as we can,” said Vermont Republican state Rep. Michael Marcotte, who said his district includes cosmetics manufacturer Rozelle Cosmetics, in Westfield.
Democratic state Sen. Virginia Lyons, the chief sponsor of the Vermont bill, said it is particularly important to get PFAS out of products that are essential to consumers.
“There are some consumer products where you can say, ‘I don’t need to buy that, because I don’t want PFAS,’” Lyons said. “But it’s really tough to say that [about] a menstrual product.”
California’s latest PFAS measure, which Democratic Gov. Gavin Newsom signed last month, specifically bans the use of PFAS in menstrual products. Democratic Assemblymember Diane Papan, the author of the bill, said it was particularly strong because it covers both intentional and unintentional uses of PFAS, so “manufacturers will have to really be careful about what comes in their supply chain.”
While more states enact laws focused on specific products, Maine is preparing to implement the world’s first PFAS ban covering all consumer goods. The Maine law, which is scheduled to take effect in 2030, will include exceptions for “essential” products for which PFAS-free alternatives do not exist. Washington state has also taken a sweeping approach by giving regulators strict timelines to ban PFAS in many product categories.
