Sensitivity to Pollution and Envirotoxins
Detox efficiency for VOCs, exhaust, fragrances, and pesticides varies. Higher-sensitivity individuals feel city air, new car smell, and perfume counters—and often recover dramatically with cleaner environments and air filtration. It's not being "difficult." It's biology.
What this measures
How your DNA shapes sensitivity to pollution and envirotoxins.
NQO1 (NAD(P)H quinone dehydrogenase 1) is a key Phase II enzyme that protects against the oxidative damage from air pollution and many environmental toxins. GSTM1, GSTT1, and AHR (the aryl hydrocarbon receptor) handle clearance of specific environmental pollutant classes including PAHs, diesel exhaust, and industrial chemicals.
Carriers of NQO1 reduced-activity variants are associated with elevated oxidative damage from given pollution exposure levels — and may experience respiratory or systemic inflammatory symptoms in environments that don't bother neighbors. Carriers of GSTM1-null or GSTT1-null variants are associated with reduced clearance of specific pollutant classes. AHR variants shape inflammatory response.
Cruciferous vegetables (sulforaphane specifically) potently activate NQO1 and the broader Nrf2 antioxidant pathway. HEPA filtration significantly reduces indoor particulate exposure. Limiting outdoor exercise during high-pollution periods reduces acute load. Adequate antioxidant intake (vitamins C and E, polyphenols) buffers oxidative stress.
The "I felt better when I moved out of the city" or "wildfire smoke really hits me" pattern often reflects a variant-driven sensitivity rather than universal toxicity. Which NQO1/GST/AHR combination you carry decides whether pollution exposure is one of the more consequential environmental inputs to manage.
Sensitivity to Pollution and Envirotoxins is one specific finding in this system. Your Genomic Lifestyle Optimization Report shows where your variants place you on the toxin sensitivities spectrum — and what you can do about it.
In your report
Where Sensitivity to Pollution and Envirotoxins lives inside your Genomic Lifestyle Optimization Report.
Sensitivity to Pollution and Envirotoxins renders as a dark-background card with a color marker calibrated to your specific variants. The card opens with the gene mechanism, shows your result at a glance via that marker, and closes with a practical, mechanism-led recommendation — what to eat, what to time, what cofactors to support.

Questions people ask
About Sensitivity to Pollution and Envirotoxins.
- How does my DNA influence sensitivity to pollution and envirotoxins?
- Why a scented candle is invisible to one nervous system and a four-hour headache for another. The TRPA1 receptor, the GST and NAT2 detox enzyme families, the HFE iron-loading variants, and the MTHFR methylation cycle together calibrate where your environmental tolerance threshold sits.
- What kind of test do I need to see my Sensitivity to Pollution and Envirotoxins result?
- Whole-genome sequencing at 30× clinical depth. Consumer SNP-chip tests like 23andMe or AncestryDNA only read ~0.02% of your DNA and miss most of the variants this analysis needs. Mosaic reads all 3 billion base pairs and produces the full 108-insight report.
- How is Sensitivity to Pollution and Envirotoxins different from clinical lab testing?
- Clinical labs measure downstream biomarkers — blood levels, hormone values, metabolic byproducts — at a single point in time. Genomic insights like Sensitivity to Pollution and Envirotoxins reveal the underlying variant that shapes the biology, which is constant for life. The two are complementary: labs show the current snapshot; genomics shows the long-term tendency and where lifestyle leverage is highest.

Heavy Metal Health Impact
Detox speed for mercury, lead, cadmium, and arsenic varies dramatically between people. Slow detoxers accumulate more from the same everyday exposure everyone gets—and benefit most from targeted chelation, prevention strategies, and cleaner sourcing.

Histamine Metabolism
DAO and HNMT enzymes break down histamine from wine, cheese, fermented foods, and leftovers. If yours run slow, you know exactly what happens—flushing, headaches, racing heart, or IBS symptoms within an hour of sushi. This confirms it's not "all in your head."

Histamine Production
Some immune systems overproduce histamine even without obvious allergens. This explains year-round congestion, itching, or hives that antihistamines only partly control—because you're constantly producing more than you can clear.

Histamine Receptor Function
Same histamine level, wildly different reaction. High receptor sensitivity turns normal amounts into hives, racing heart, or anxiety—even when production and breakdown are fine. The issue isn't how much histamine you have. It's how loudly your body hears it.

Histamine Transport Efficiency
Even with good breakdown enzymes, poor cellular export traps histamine inside cells, where it keeps causing problems. This variant explains widespread symptoms from tiny triggers that "shouldn't" bother anyone—and why even low-histamine diets don't fully work.

Inorganic Metal Processing Capacity
Lead from old pipes, cadmium from soil, and aluminum from cookware—your clearance rate for these common exposures varies. Slow processors benefit from better water filtration, periodic testing, and cookware upgrades. Fast processors have more natural resilience.
