Pollution is a problem that affects everyone, no matter where they live. Even if you reside in a rural area, you are still subject to many types of pollution, both outdoors and inside your home.
Today we will look at several air quality sensors that you can use with a microcontroller. We’ll test them out using both an ESP323 and an Arduino, and we’ll also compare the readings to a commercial air quality meter to see if there is any correlation between readings.

EPA Takes Important Step to Advance PFAS Strategic Roadmap, Requests Public Input and Data to Inform Potential Future Regulations under CERCLA
EPA Takes Important Step to Advance PFAS Strategic Roadmap, Requests Public Input and Data to Inform Potential Future Regulations under CERCLA
WASHINGTON (April 13, 2023) — Today, the U.S. Environmental Protection Agency (EPA) is issuing an Advance Notice of Proposed Rulemaking (ANPRM) asking the public for input regarding potential future hazardous substance designations of per- and polyfluoroalkyl substances (PFAS) under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as “Superfund.”
“Today’s announcement highlights EPA’s commitment to transparency and the use of the best available science to tackle PFAS pollution and protect people from exposure to these forever chemicals,” said Barry N. Breen, Acting Assistant Administrator for EPA’s Office of Land and Emergency Management. “This is a key commitment under the Agency’s PFAS Strategic Roadmap and will provide an opportunity for a large and diverse group of stakeholders, including the public, state and local governments, Tribes, industry, businesses, environmental groups, and universities, to provide input and help EPA gather the latest science and information regarding PFAS.”
This request for input and information follows EPA’s September 2022 proposed rule to designate two PFAS — perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic
Through this ANPRM, EPA is seeking input on whether to propose to designate additional PFAS, including HFPO-DA, sometimes called GenX, and compounds that degrade in the environment by processes such as biodegradation, photolysis, and hydrolysis, to form certain PFAS. EPA is also seeking information on whether some PFAS compounds can or should be designated as a group or category.
PFAS can accumulate and persist in the human body for long periods of time and evidence from laboratory animal and human epidemiology studies indicates that exposure to these compounds may lead to cancer, reproductive, developmental, cardiovascular, liver, and immunological effects. Many known and potential sources of PFAS contamination are near communities already overburdened with pollution.
A Federal Register Notice has been published in the Federal Register at docket EPA-HQ-OLEM-2022-0922 and can be viewed on www.regulations.gov. The ANPRM will be open for a 60-day comment period through June 12, 2023.
EPA intends to carefully review all the comments and information received in response to this ANPRM.
An agency may publish an ANPRM in the Federal Register to seek input and obtain more information. If EPA decides to move forward with designating additional PFAS compounds as hazardous substances under CERCLA, the agency will publish a proposed rule and seek public comment.
EPA is not reopening or otherwise proposing to modify any existing regulations through this ANPRM.
Under the Roadmap, EPA is working across its programs and with its federal partners across the Biden-Harris Administration to develop solutions to the PFAS crisis and protect public health.

Hemp plants can suck PFAS, aka "forever chemicals," out of the ground
Hemp, a variety of the plant Cannabis sativa, is often overshadowed by marijuana — a genetically distinct form of cannabis. Used for food, clothing, fuel, and plastics, it’s the seemingly more domestic member of the family.
However, new research suggests we should pay more attention to this nonpsychoactive substance. Hemp, scientists say, has an eco-friendly superpower: It can rid the environment of toxic chemicals.
Members of the Micmac (Mi'kmaq) Nation — a tribe indigenous to what’s now known as Canada’s eastern Maritime Provinces and parts of the northeastern United States — the activist group Upland Grassroots, and research scientists came together in 2019 to test methods for removing per- and polyfluoroalkyl substances (PFAS) from land located at the Loring Air Force Base. After years of lobbying and dispute, portions of the former bomber base were given back to the Aroostook Band of Micmacs in 2018.
On Tuesday, the eclectic team published a commentary reflecting on their work and progress in the journal Cell Press. The project, so far, is a success: Results suggest planting small fields of fiber hemp removed a primary type of PFAS at the polluted site, a chemical called perfluorooctanesulfonic acid (PFOS).
“Protecting the land is part of the Micmac beliefs,” Chief E. Peter Paul of the Micmac Nation said in the commentary. “Anything we can do to contribute to making the environment better, we want to be a part of.”
What you need to know first — The idea of removing toxic contaminants from the soil by planting certain plants is known as “phytoremediation.”
Hemp is “versatile in extracting many different kinds of chemicals from the soil,” Chelli Stanley, a member of Upland Grassroots, states in the commentary.
Previous research has also demonstrated industrial hemp can be effective in phytoremediation.
“Hemp phytoremediation has been previously used for other types of soil contaminants – mainly metals,” Sara L. Nason, one of the lead researchers on the project, tells Inverse. Nason is a scientist affiliated with the Connecticut Agricultural Experiment station.

I would like to appeal to the logical area of the brain for a moment. We know we're under attack by the state. Rather than expend our energy debating the precise nature of each tool being used to murder us, I suggest we focus our attention and talk about the only peaceful way out https://t.co/2I6l0V6h3h

Ohio Trainwreck Bioremediation Soil Treatment Research
JOINT STUDY OF BIOREMEDIATION AT PILOT SCALE FOR DETOXIFICATION OF HERBICIDE/DIOXIN IN DA NANG HOT SPOT, VIETNAM
Conclusions Aerobic bioremediation is capable of significantly reducing TCDD toxicity (p=0.0026). Bioaugmentation with small amounts of treated soil or contaminated sediment may be effective for anaerobic treatment. However, if suitable growth conditions are provided, the indigenous microbes in the mixed soil and sediment at Da Nang appear capable of degrading TCDD without adding another source of microbes. Anaerobic bioremediation rate is about half the rate of aerobic treatment, but the results are not as significant (p=0.25). From our of point active landfill containing both aerobic and anaerobic degradation become feasible resolution for detoxification of heavy herbicide/dioxin in full scale in Vietnam.
Bioremediation is recognized as a “Green Technology,” which has a very low energy requirement and produces few emissions. Bioremediation is a permanent solution which produces a soil which can be returned to beneficial use. Knowledge gained from this project by both Vietnamese and US scientists will allow for design of customized recipes suitable for addressing dioxin and other persistent organic pollution problems throughout Vietnam and elsewhere
