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.

Parasite Test Types, Explained (2026)
Stool O&P, antigen/PCR panels, blood tests by parasite—clinician-ordered, exposure-matched; no cleanse kits.

Mold Remediation, in Priority Order (2026)
Moisture control first, then remove damaged porous materials, PPE, and clean—bleach last, fogging theater later.

Microplastics: From Lab Headlines to Daily Habits (2026)
Map uncertain biomarkers to high-yield habits: no heat in plastic, water choices, dust, laundry—without purity panic.

How to Actually Remove Fluoride From Water (2026)
RO, distillation, and specialty media ranked by fluoride reduction honesty—measure mg/L before buying.

Whole-House vs Point-of-Use Water Treatment: Choosing the Right Layer
POU RO/GAC targets drinking/cooking; whole-house systems address sediment, hardness, or volatile chemicals at every tap—with tradeoffs.

UV and Distillation for Drinking Water Pathogens: What They Do and Miss
UV inactivates many microbes without chemicals; distillation separates pure water vapor—neither is a universal metals/PFAS solution.

RO Remineralization Debate: Minerals, Taste, and What Evidence Actually Requires
RO strips dissolved solids; remineralization improves taste and can restore some hardness—diet remains the main mineral source for most people.

NSF/ANSI 42, 53, 58, and 401: Water Filter Standards Decoder
42 aesthetic, 53 health adsorption, 58 RO, 401 emerging compounds—certification is claim-specific and model-specific. “Tested to NSF” is weaker than listed certification.

Heavy Metals in Drinking Water: Lead, Arsenic, and Copper Filter Priorities
Lead from plumbing, arsenic from geology, copper from corrosion—each needs different testing and treatment logic.

U.S. Endemic Parasites and CDC’s Five NPIs
Pinworm, Giardia, Crypto, Toxoplasma, and trichomoniasis are everyday U.S. realities. CDC’s neglected parasitic infections: Chagas, cysticercosis, toxocariasis, toxoplasmosis, trichomoniasis.

Travel Parasites: CDC Yellow Book Priorities
Malaria first for fever, then schistosomiasis freshwater rules, enteric parasites after long trips, leishmaniasis ulcers, and Strongyloides before future steroids.

Parasite Overdiagnosis: When Not to Treat
In high-sanitation settings most bloating is not occult helminthiasis. No diagnosis → no chronic antiparasitic self-treatment. Endemic MDA ≠ Seattle herbal monthly deworming.

Nematodes Deep Dive: STH, Strongyloides, and Pinworm
1.5 billion people with soil-transmitted helminths globally; U.S. pinworm dominates domestic worm complaints. Intensity drives morbidity; Strongyloides can autoinfect for decades.

Global Burden of Soil-Transmitted Helminths and Neglected Tropical Diseases
STHs and other NTDs still cause massive disability in endemic regions; deworming and WASH are public health, not biohacking.

Parasite Prevention: Food, Water, Travel, and Household Hygiene
Prevention is exposure control—safe water, food hygiene, travel counseling, handwashing—not annual “parasite cleanses.”

Parasite Prevention Stack: Food, Water, Travel, and Home
Cook it, peel it, or forget it; safe water; hand hygiene; pinworm household rules; destination-specific malaria and freshwater advice—prevention outruns cleanses.

Parasite Diagnostics Map: O&P, Antigen, PCR, and Serology
Match method to syndrome: microscopy O&P, stool antigen, multiplex PCR, and serology each answer different questions—with different false-negative windows.

Trichothecenes and Stachybotrys: Context Without Panic
Stachybotrys chartarum (“black mold”) can produce trichothecenes in culture, but residential disease claims outran evidence. Dampness remediation still matters; toxin folklore is not the mechanism card for every symptom.
