# Human Toxicity, Non-Cancer (PEF)

> Non-cancer human toxicity impact category in the PEF methodology

<Warning>
  This impact category is only applicable with the **Product Environmental Footprint (PEF)**
  methodology.
</Warning>

## Definition

Human Toxicity, Non-Cancer assesses the potential for substances to cause non-cancer health effects. The unit is **CTUh**.

## Environmental Mechanism

Exposure to toxic pollutants can lead to chronic respiratory, neurological, or reproductive issues. Releases occur via air, water, and soil pathways.

## Calculation in GREENZERO Journey

1. Collect emissions of non-carcinogenic toxic substances.
2. Multiply by ILCD characterization factors (CTUh).
3. Sum the results for the total impact.

  **About ReCiPe 2016**

  ReCiPe 2016 is a life cycle impact assessment (LCIA) method that provides characterization factors for converting inventory data into environmental impact indicators. It is not a methodology itself, but rather a comprehensive database of impact assessment factors developed by Dutch research institutes.

  The method provides characterization factors that translate emissions and resource use into standardized impact units (e.g., kg CO₂ eq. for climate change, kg SO₂ eq. for acidification). GREENZERO Journey follows ISO 14040/44 methodological standards while using ReCiPe 2016 characterization factors for impact calculations.

  ReCiPe 2016 does not cover this impact category, so PEF results are provided separately.
</Info>

## Environmental Cost Conversion

No CE Delft cost factor is currently available; the impact is reported in CTUh.

## Example Calculation

For an emission total of **2e-6 CTUh** the result is simply:

```
Impact = 2e-6 CTUh
```

## Interpretation

Higher values signal greater potential for non-cancer health issues. Key drivers include solvents and heavy metals.

## Reduction Strategies

* Replace hazardous substances
* Improve workplace and community emissions controls

## Data Quality Considerations

* Local exposure patterns strongly influence actual risk
