Mounting about ?

[INky]

Hi everybody, I read an article about plastic pollution and marine litter and in the article
there was this sentence:

Reports are mounting about impact of microplastics on all marine life.

I looked up for the German meaning of the word mounting about but I did not find anything.
Could anybody help me to find the fitting German translation to this context.

Thanks in advance !

Mounting (up) means that the reports are piling up in the sense of increasing.

I hope this helps.
