Benzine, a carcinogen that can cause cancer in humans can form in beverages containing

0:13.6

benzoyate preservatives in certain acids.

0:16.6

For example, fanta, soda.

0:19.1

Interesting that Coca-Cola chose to disclose that the artificial colors it uses can cause

ADHD symptoms rather than just not using them.

Anyway, the U.S. Food and Drug Administration was informed by the soda industry about the

This prompted a national survey of nearly 200 beverages for the presence of benzene,

soda and other beverages.

to reach since benzene spews from cigarettes, car exhaust, and fireplaces.

California holds the line at one part per billion,

1:12.6

but its goal for public health is 0.15 parts per billion

1:16.6

based on cancer risk from leukemia,

1:19.6

because the lifetime exposure to one part per billion

1:21.6

could cost seven additional people per million to get cancer,

1:24.6

who otherwise wouldn't.

1:26.6
