Dose-aware exposure science for modern life — citations first, slogans last.
Environmental health is the science of what gets into your body from air, water, food packaging, personal care, and buildings — and what that dose actually means. This section covers PFAS and forever chemicals, microplastics, endocrine-disrupting fragrances, mold and dampness, non-ionizing EMF, fluoride policy levels, hormones in drinking water, and water filtration including reverse osmosis. Every guide dual-sources contested claims, keeps units honest (ppt vs ppm, µT vs SAR), and separates ecological signals from human clinical risk when the dose bridge fails.

CDC Neglected Parasitic Infections (NPIs): The U.S. Framework Explained
CDC prioritizes five NPIs in the United States—Chagas, cysticercosis, toxocariasis, toxoplasmosis, and trichomoniasis—for burden, severity, and preventability—not internet “mystery parasite” lists.

The Home Water-Testing Panel for Homeowners (2026)
What to test first on municipal vs well water, how to read results, and when to filter after—not before—data.

Parasite Symptoms: When to Test and When to Wait (2026)
When GI and travel symptoms warrant stool testing—and when parasite cleanse marketing is the wrong tree.

Mold-Testing Myths, Corrected (2026)
Why moisture control beats air-spore theater, when testing helps, and how remediation hierarchy actually works.

Reducing Endocrine Disruptors at Home (2026)
Practical exposure cuts: plastics heat, fragrance, dust, receipts, pesticides—ranked without purity paralysis.

Water Filter Selection Framework: Test, Match Claims, Maintain
Start with water quality data, map contaminants to certified technologies, then budget maintenance. Skipping tests is how households buy the wrong system twice.

U.S. Endemic Parasites and Neglected Parasitic Infections (NPIs)
America is not parasite-free. Pinworm, waterborne protozoa, Toxoplasma, trichomoniasis, babesiosis, and five CDC NPIs define the domestic map.

Trichothecenes, Stachybotrys, and Indoor Mold Toxins
Satratoxins in culture versus residential dose reality—separating lab toxins from bathroom fear.

Sediment and Carbon Water Filters: What They Do and Don't
Sediment cartridges protect downstream gear. Activated carbon improves taste and reduces many organics and chlorine—not nitrate, not most hardness, not all microbes.

Reverse Osmosis Membrane Performance: What RO Actually Removes
RO semi-permeable membranes reject many dissolved ions and molecules when pressure, recovery, and membrane integrity are right—maintenance decides real-world results.

Human Protozoa: Intestinal, Blood, and Tissue Compartments
Protozoa are not worms. Split them by gut, blood/vector, and tissue-cyst niches—Giardia and Crypto are not malaria are not Toxoplasma reactivation.

Priority U.S. Clinical Parasite Syndromes Clinicians and Patients Meet
Pinworm, Giardia, Crypto, Cyclospora, Toxoplasma syndromes, trichomoniasis, and babesiosis dominate U.S. reality more than tropical Ascaris fear copy.

Parasite Transmission Pathways: Food, Water, Vectors, Blood, Zoonoses
CDC groups parasitic transmission by pathway. Prevention and clinical suspicion follow food, water, insects, blood, and animals—not generic detox stories.

Organic Farming Environmental Co-Benefits and Health Boundaries
Biodiversity, pesticide load on landscapes, climate tradeoffs—and what co-benefits do not prove for personal disease risk.

Textiles, Personal Care, and Dermal Microplastic Pathways
Synthetic textiles shed microfibers in wash and wear. Microbead bans cut intentional cosmetics particles—but skin is a weak route for intact micron plastics vs chemical additives.
