What do the Clean, Low, Watch and Swap levels mean?

They are cut from a continuous concern level the app computes from the sourced claims that the chosen evidence lens shows: each claim counts its concern class, tier weight, confidence and dose relevance, combined worst-first with a decay so one serious finding outweighs many small ones, then scaled by how much of the substance reaches you in this use. Clean is below 0.35, Low below 1.1, Watch below 2.0 and Swap above that, on a 0 to 3 scale.

Is Mercury safe in drinking water?

Q: Is mercury safe in drinking water?

Under the app's default Cautious lens, mercury in drinking water rates Swap: the app would put this near the top of your swap plan. 3 sourced concerns count (suspected carcinogen, consensus tier; endocrine, consensus tier; metabolic, consensus tier). This is research with sources, not medical advice.

Where it turns up: industrial pollutant, neurotoxin, toxic. Detox My Life researched mercury under one use, because the same substance means something different in each use. Every claim below carries its evidence tier, how sure the research is that it applies here, and the sources it cites. The level is computed by the app's own deterministic engine, so the page says exactly what the app would.

Mainstream shows consensus claims only; Cautious adds emerging research; Based adds fringe claims, labelled as such. The last column counts, under Cautious, the sourced concerns, the findings in its favour and the fringe claims Based would add.

Safer swaps: the app's swap catalog has no entry tied to this ingredient yet. When you scan a product that contains it, the app suggests cleaner alternative types for that product; the swap categories list what the catalog covers today.

Sourced concerns (3)

ConsensusSuspected carcinogenconfidence 50%

The U.S. Environmental Protection Agency (EPA) has determined that mercuric chloride (an inorganic mercury salt) and methylmercury (an organic mercury compound) are possible human carcinogens (Group C). The International Agency for Research on Cancer (IARC) classified methylmercury compounds as possibly carcinogenic to humans (Group 2B).

Why here: While the primary concern for mercury in drinking water is inorganic mercury, both inorganic and organic forms have been evaluated for their carcinogenic potential.
What would have to be true: Exposure to mercury compounds through environmental pathways, including drinking water, has been assessed for carcinogenic risk.
The other side: The EPA concluded in 2005 that environmental exposures to inorganic mercury and methylmercury are not likely to cause cancer in humans. IARC designated inorganic mercury and elemental mercury as not classifiable for causing cancer in humans.

ConsensusEndocrineconfidence 50%

Mercury is an endocrine disruptor, meaning it can interfere with the body's hormone system, affecting processes like growth, metabolism, and reproductive health.

Why here: Exposure to endocrine-disrupting chemicals, including mercury, can occur through contaminated drinking water.
What would have to be true: Ingestion of drinking water containing mercury, even at low concentrations, can have long-term health effects.

ConsensusMetabolicconfidence 50%

Long-term consumption of drinking water containing inorganic mercury above the Maximum Contaminant Level (MCL) of 2 parts per billion (ppb) can cause damage to the kidneys and nervous system, including the brain.

Why here: Inorganic mercury can enter drinking water from natural geological deposits, industrial contamination, mining operations, and runoff from landfills and croplands.
What would have to be true: Ingestion of drinking water with inorganic mercury concentrations exceeding 2 ppb (0.002 mg/L). The World Health Organization (WHO) guideline value for inorganic mercury in drinking water is 0.006 mg/L.
The other side: Acute mercury poisoning from a single glass of highly contaminated water is not commonly found in drinking water, but mercury can accumulate in the system over time.

Not researched here

The engine has no dossier for mercury when cooked with heat, in cold food, as a finishing ingredient, in heated food packaging or other uses. The app researches an ingredient for the use it infers from your product, so a scan fills these in; this page only shows what has already been researched and source-verified.

This is research, not medical advice. Detox My Life shows sourced claims sorted by evidence tier. It does not diagnose, treat, or tell you to start or stop anything. Talk to a qualified professional about your health.

Scan your own. The app reads any product label with your camera, works out how you are about to use it, and researches every ingredient for that use with live sources. Every scan adds to a Detox Score for your home, where 50 is a typical home in your region, and a plan of next swaps.
