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.

Sourced concerns (3)

ConsensusSuspected carcinogenconfidence 100%

Short-chain chlorinated paraffins (SCCPs) are classified as possibly carcinogenic to humans (Group 2B) by the International Agency for Research on Cancer (IARC) and are listed as "Reasonably Anticipated to Be a Carcinogen" by the U.S. National Toxicology Program (NTP), based on sufficient evidence of carcinogenicity in experimental animals where oral exposure caused tumors in the liver, thyroid, and kidney.

Why here: SCCPs are persistent and bioaccumulative, leading to their presence in the environment and food chain, which can result in dietary ingestion by children.
What would have to be true: Ingestion of SCCPs through contaminated food, water, soil, or dust, or from mouthing products containing SCCPs.
The other side: The German Federal Institute for Risk Assessment (BfR) states that current daily intake levels of SCCPs in Europe are so low that they do not give cause for concern and are far below amounts expected to cause health impairment over a lifetime.

ConsensusRestrictedconfidence 100%

Short-chain chlorinated paraffins (SCCPs) have been globally banned under the Stockholm Convention on Persistent Organic Pollutants (POPs) since 2017, effective December 2018, with exemptions for their use expiring in 2024.

Why here: The global ban and restrictions aim to reduce environmental contamination and subsequent human exposure, including through ingestion, particularly for vulnerable populations like children.
What would have to be true: The ban addresses the presence of SCCPs in various products and the environment, which can lead to ingestion.
The other side: None.

Short-chain chlorinated paraffins (SCCPs) are classified as persistent, bioaccumulative, and toxic to aquatic organisms at low concentrations, leading to their widespread presence in the environment, wildlife, and humans.

Why here: The environmental persistence and bioaccumulation of SCCPs mean they can enter the food chain and accumulate in various food items, leading to dietary exposure in children.
What would have to be true: Ingestion of SCCPs through contaminated food (e.g., poultry, eggs, cow's milk, dairy products, vegetable oil), water, soil, or dust.
The other side: None.

Sourced concerns (3)

ConsensusSuspected carcinogenconfidence 100%

Short-chain chlorinated paraffins (SCCPs) with an average chain length of C12 and a chlorination degree of approximately 60% are classified by the International Agency for Research on Cancer (IARC) as possibly carcinogenic to humans (Group 2B) based on sufficient evidence in experimental animals.

Why here: SCCPs are semi-volatile organic compounds used in various consumer and building products, leading to their presence in indoor air and subsequent human inhalation exposure.
What would have to be true: Adult exposure to sum of chlorinated paraffins (CPs), dominated by SCCPs in air, via the indoor environment is estimated at approximately 1 µg per day, with inhalation being the predominant pathway for SCCPs. Indoor air concentrations of SCCPs have been reported up to 210 ng m-3.

ConsensusRestrictedconfidence 100%

Short-chain chlorinated paraffins (SCCPs) were globally banned under the Stockholm Convention on Persistent Organic Pollutants, effective December 2018, due to their classification as persistent, bioaccumulative, and toxic (PBT) substances.

Why here: The persistence and semi-volatile nature of SCCPs allow them to remain in the indoor environment and partition into the air, leading to continuous human exposure.
What would have to be true: SCCPs are detected in indoor air, with concentrations ranging from <5-210 ng m-3, and inhalation is a predominant exposure pathway for adults, contributing significantly to overall human exposure.

EmergingEndocrineconfidence 100%

In vitro studies suggest that short-chain chlorinated paraffins (SCCPs) can induce estrogenic effects, including mediation by estrogen receptor α (ERα), and stimulate the secretion of 17β-estradiol (E2).

Why here: SCCPs are present in indoor air as semi-volatile compounds from various products, leading to potential human inhalation and subsequent internal exposure.
What would have to be true: SCCPs have been detected in indoor air at concentrations up to 210 ng m-3, and inhalation is a significant pathway for human exposure.

Sourced concerns (5)

ConsensusSuspected carcinogenconfidence 50%

Short-chain chlorinated paraffins (SCCPs) are classified as possibly carcinogenic to humans (IARC Group 2B) and reasonably anticipated to be human carcinogens (NTP) based on sufficient evidence in experimental animals.

Why here: Inhalation exposure to SCCPs can occur from mists generated during metalworking, spray application of products like paints, adhesives, and sealants, and from indoor air, leading to potential systemic exposure.
What would have to be true: Inhalation of SCCP-containing mists or indoor air containing SCCPs, with estimated potential occupational inhalation exposure ranging from 1.8 to 8.3 mg/day in some scenarios.

ConsensusEnvironmentalconfidence 50%

Short-chain chlorinated paraffins (SCCPs) are persistent, bioaccumulative in humans and wildlife, and toxic to aquatic organisms, leading to their global ban under the Stockholm Convention on Persistent Organic Pollutants.

Why here: Inhalation is a route of human exposure, contributing to the overall body burden of these bioaccumulative substances, which are found globally in the environment, wildlife, and humans.
What would have to be true: Inhalation of SCCPs from environmental sources, including indoor air, where they have been measured.

EmergingMetabolicconfidence 50%

Studies suggest that exposure to short-chain chlorinated paraffins (SCCPs) may lead to damage in multiple organs, including the liver, kidney, and thyroid.

Why here: While primarily observed in oral animal studies, SCCPs are absorbed into the body, and inhalation is a significant exposure pathway, suggesting potential for similar systemic effects if absorbed.
What would have to be true: Systemic absorption of SCCPs following inhalation from indoor air or product mists.
