What does the term 'emerging pollutants' refer to in the context of the study?

the other choices is New pollutants induced to environment due to Natural disaster is not correct it induced by inefficeint waste water treatment system and Pollutant in this article not only used in Contruction . the pollutant doesn't phase out so The correct answer is Pollutant that have Recently Been discovered and May not Degrade easily.

emerging pollutants is a chemicals that are persistent, bioaccumulative and toxic in the environment. and maynot degrade easily Emerging mean it mot only can affects to human but also affects to the environment.
