Bioaccessibility results for solder glass sample:

The bioaccessibility of inorganic glass has been investigated experimentally in vitro by simulating dissolution under physiological conditions considered to mimic the most relevant exposure routes (oral, dermal and inhalation). Dissolved Pb concentrations were between 0.65 µg/L (GMB 24h) and 85033 µg/L (GST 24h)

Bioaccessibility results for optical glass sample:

The bioaccessibility of inorganic glass has been investigated experimentally in vitro by simulating dissolution under physiological conditions considered to mimic the most relevant exposure routes (oral, dermal and inhalation). Dissolved Pb concentrations were between <LOD µg/L (GMB,PBS 24h) and 12332 µg/L (GST 24h)
