How I run things.
If you're going to trust what I write about chemicals in your dorm, you should know exactly how I find out, what I get wrong, and where my money comes from. This page is the receipts.

1. The instruments I use
Most testing happens through university lab access and student-level research workflows.
FTIR
Fourier-Transform Infrared Spectroscopy
For polymer types and common additives.
PID
Photoionization Detector
For real-time VOC measurements in indoor air.
PM
Portable particulate sensors
For dorm and rental air readings.
2. How I choose what to test
USE
Things Gen Z actually uses
Candles, sheets, snack bars, period products, and skincare you can buy on a college budget.
EVIDENCE
Things with real evidence
I won't run a one-off viral panic test if there's no underlying mechanism.
ASKS
Things you've asked about
A meaningful share of testing topics come from DMs, comments, and lab@lowtoxlab.com.
3. How reader-submitted ideas are screened
Reader submissions help shape the test queue, but they do not automatically become public tests. I screen every idea for specificity, relevance to student life, safety, privacy, cost, and whether the result would help more than one person. I do not accept unsafe, invasive, illegal, or private samples. I do not diagnose symptoms, publish medical records, reveal school or dorm details, or turn a comment into a brand-attack post without strong evidence and context. The best submissions name a specific room, product claim, campus space, material, or digital habit, then explain what made the question worth asking.
4. How I read the literature
When I cite a study, I check whether it is peer-reviewed, whether methods and conflicts are disclosed, whether independent groups replicated it, who funded it, and whether the dose and model apply to humans in real life. Whenever possible, I link the original study, DOI, or regulatory source.
5. Evidence levels
A
Strong
Multiple peer-reviewed studies, regulatory consensus, large sample sizes.
B
Moderate
Some peer-reviewed evidence; mechanism is plausible; not yet replicated widely.
C
Early
Single study or preliminary evidence; mechanism is suspected but not confirmed.
D
Disputed
Real disagreement among scientists; I'll show you both sides.
6. Conflict of interest disclosure
As of May 2026: self-funded. No active affiliate relationships, no brand partnerships, and no PR gifts in exchange for coverage. I am an undergraduate student at a U.S. university; the university does not endorse, fund, or review this site.
7. Editorial independence
No brand or sponsor has approved a piece of content on this site, and none will. If a result is inconvenient, I publish it anyway.
8. Error correction policy
Send corrections to corrections@lowtoxlab.com. Typo or link errors are fixed silently within 48 hours. Factual errors are fixed within 7 days with a visible updated note. Significant interpretation errors get a correction note and preserved original wording for transparency.
9. What I won't do
I won't write a "this product gave me cancer" headline. I won't run a test specifically to make a brand look bad. I won't manufacture urgency. I won't sell your email address.
10. Medical disclaimer
I'm a chemistry student, not a doctor. Nothing on this site constitutes medical, psychological, legal, or professional advice.
