Yes and it is being thoroughly investigated, as it should be. But so far nothing has been found, so sensationalism is only detrimental as:

• it takes away focus from materials that have actually been found to be harmful
• puts public pressure on researchers, and if they don't find something quick it might be the end of the whole field, and then they might have difficulties funding research on future polymers
• builds up anxiety about something we can't do anything about (the plastics are there and they're here to stay for a while)
