| Mutagenic properties of emissions are essentially related to the extractible fraction of the organic particulates. |
|
| Present legislations focus on carbonaceous particulate emissions, without considering separately soot particules and extractible matter. |
|
| It turns out that, by 2020, there will be 7.25 million tons of extractible plastic in the oceans, most of it floating relatively close to the surface. |
|
| The extractible substances in pulps are mainly resins, waxes, fatty acids and similar components of wood not removed in pulping and bleaching processes. |
