Tetrachlorethylen (PCE), eine Chemikalie, die in der chemischen Reinigung und in Konsumgütern wie Klebstoffen, Fleckenreinigern und Edelstahlpolitur verwendet wird, erhöht nachweislich das Risiko einer Leberfibrose, die zu Leberkrebs, Leberversagen oder zum Tod führen kann

>PCE is a human-made, colorless liquid used in dry cleaning, household goods and industrial settings to remove grease and for other purposes.
>
>People are typically exposed to PCE through the air — for example, the chemical can be slowly released into the air over time from clothes that have been dry cleaned. PCE can also be present in drinking water from contaminated sites due to spills and improper disposal of PCE that can seep into the soil and then into the groundwater.

>The study did show that those most at risk of PCE exposure were from higher-income households. “People with higher incomes may be more likely to use dry cleaning services, which could increase their exposure to PCE,” said Lee. “However, people who work in dry cleaning facilities may also face elevated risk due to prolonged, direct exposure to PCE at work.”

>The researchers also found that for every one nanogram per milliliter increase in PCE concentration in the blood (one nanogram is one-billionth of a gram), the individual’s odds of having significant liver fibrosis increased five-fold.

That is a little concerning to me. I worked at a dry cleaner for 2 years in the 1980s, and there was no PPE ever offered. The ventilation was open the back door.
