Brain Shrinkage, Memory Problems, Depression Linked to Air Pollution Chemicals

Two separate scientific studies have revealed some sobering news about the link between air pollution chemicals and serious brain harm.  In the first study, higher exposures to air pollution chemicals were associated with increased depressive symptoms and subsequent memory decline. In the second study, people who had higher levels of air pollution exposure had more brain shrinkage–the kind of shrinkage commonly seen in people suffering from Alzheimer’s disease.

Neurotoxic Flea Treatment for Pets Contaminating Water

Scientists have recently discovered that pesticides commonly used as flea treatments for pets are contaminating rivers. The new research reveals widespread contamination, with two neurotoxic pesticides found in concentrations that far exceed accepted safe limits.  More specifically, researchers have found widespread contamination of rivers with two neurotoxic pesticides commonly used in veterinary flea products: fipronil and the neonicotinoid imidacloprid. 

Household Chemicals PFAS and Phthalates Alter Gut Microbiome: Study

In another new study scientists have again found that chemicals commonly found in our food and home environment alter our gut microbiome.  This is a critical confirmation of the findings found previously because gut microbiome–the community of microorganisms (bacteria, fungi, and viruses) that inhabit the human gastrointestinal tract–has recently come under close scrutiny by the medical science community because several serious health conditions have been suspected to be linked to an imbalance in gut microbiome. 

Our Most Toxic Chemical: Who is Doing What about PFAS?

What are the Effects of PFAS Chemical?   Because of their toxicity at extremely low concentrations, there are risks from PFAS bioaccumulation.  In addition to their presence in the human body–where, among other serious effects, they are linked with increased rates of some types of cancer, hormonal disruption, and immune responses–PFAS chemicals (a class of over 3000 compounds) are released into the environment, transported through groundwater, river, and soils, and can only be partially remediated. Scientists will be
meeting at the Geological Society of America’s 2020 Annual Meeting to learn more about this highly toxic chemical and discuss the need for more research.

Toxic Furniture and Industry Lies: Doc Recommendation

Fire retardant chemicals (also known as PBDEs) are released when humans and pets sit on furniture that contains them; they are toxic, volatile and travel widely into the air. These toxic chemicals have been linked to numerous serious health problems, including cancer. There is no scientific evidence in peer-reviewed journals that confirm these fire retardants in our sofas, beds and chairs really slow fires down enough to save lives.  These chemicals present significant risks to human health and well-being so if they do not definitively slow or retard fires, then why are they in our furniture? The HBO documentary ‘Toxic Hot Seat’ exposes the nexus of money, politics and power behind the answer.

Eye Health Threatened by Toxic Chemicals in the Air

The toxins from indoor and outdoor air pollution can trigger eye infections, dry eye disease, eye irritation, burning and itching and vision problems, including blurry vision.  This is nothing to take lightly.  Scientific studies have confirmed that if exposure to toxic air is prolonged it has the potential to cause chronic and even serious eye diseases like glaucoma.

Neurological Disorders Significantly Linked with Chemicals in Air Pollution

The results from a long-term study revealed a significant link between air pollution and an increased risk of hospital admissions for several neurological disorders, including Parkinson’s disease, Alzheimer’s disease, and other dementia-related conditions.
