Not sure if I understand you.

If you remove the ceramic material, what happens to pollution?

And this suggestion to remove ceramic material is in response to the issue that the thread-owner has posted? I mean will this fix the problem of balck smoke and oil leakage?

BTW, -my Tucson had suffered oil leakage around 2 years ago. I was loosing oil but no black smoke in the exhaust. The ASC pointed at Turbo, but after consulting a fellow Tucson owner on team-bhp (Digital_Vampire), and reading on some forums, I asked the ASC to open the complete plumbing of the air-intake, intercooler and Turbo (to check all hoses) and in deed 2 hoses had developed cracks and holes. They were replaced and the issue was solved.

Here are the details (problem, pictures and the solution) for reference:
