Sydney Beaches Reopen after Pollution Balls Clear

• Sydney beaches reopened after thousands of black pollution balls washed ashore.

• Testing found the balls to be made from chemicals similar to those in cosmetics and cleaning products.

• Around 2,000 of the mystery black balls washed onto beaches since October 15, forcing the closure of eight, including Bondi Beach.

• The Environment Protection Authority confirmed the balls are made up of fatty acids and some fuel oil.

• The balls are not harmful when left on the sand but should not be touched.

• Laboratory testing is ongoing to determine the origin of the balls.
