The municipality of Amsterdam aims to make the city greener. To gain more insight into the benefits of green infrastructure, it commissioned the development of four different scenarios. For every scenario, and for the current situation, RIVM has calculated the value for the living environment of the city.

For Allergan Biocell breast implants an increased risk of BIA-ALCL (a very rare type of lymphoma) is plausible. The cases of BIA-ALCL in the Netherlands are predominantly found with Biocell and other breast implants with a rough surface. However, RIVM found insufficient evidence that other breast implants with a rough surface present a similar risk as Biocell implants. This is due to the small number of BIA-ALCL cases and the limited use of these other implants.
