What is the primary concern regarding the release of chemicals from Personal Care Products (PCPs) into the environment?

From the text, "These chemicals are continuously released into the environment, and if not properly regulated, they can be persistent, bioaccumulative and toxic in the environment." can be imply that its the major concern of the release.

"These chemicals are continuously released into the environment, and if not properly regulated, they can be persistent, bioaccumulative and toxic in the environment." (Abstract) "As a result, PCPs are regarded as emerging environmental contaminants; arising from their persistence, exposure potentials, toxicity and environmental accumulation"

Why are some PCP contaminants referred to as "emerging pollutants"?

"However, emerging evidence suggests that some accumulate in body tissues and negatively impact humans and animals, impacting the endocrine systems and the environment since they are continuously being released and may not degenerate easily the environment. The contaminants are thus called emerging pollutants." It can be imply that it it's hard to be degenerate, thus the third choice should be eliminated. The first and the forth choices are off-topic. This mean its left with choice 2 (They accumulate in body tissues and have negative impacts)
