A possible explanation for the 'missing plastic problem': New detection technique finds microplastics in coral skeletons

These findings may also explain the "missing plastic problem" that has puzzled scientists, where about 70% of the plastic litter that has entered the oceans cannot be found. The team hypothesizes that coral may be acting as a "sink" for microplastics by absorbing it from the oceans. Their findings were published in the journal Science of the Total Environment.
