Any oil spill could be dangerous to marine life however Dr Sharon Hook, CSIRO’s principal analysis scientist, stated Sydney’s seashores can be secure for individuals as soon as the tar balls have been collected and eliminated.
They “are filled with carcinogenic compounds so you wouldn’t want people to come in contact with them,” she instructed ABC radio.
“[But] as soon as it [the beach] is cleaned it will be safe because the chemicals and tar stick together. Oil and water don’t mix … so when the beach is reopened it will be fine.”
