text: Where did you get the math for "Scientists believe coral is damaged when oxybenzone exceeds a concentration of 62 parts per trillion, which is roughly equivalent to one drop of water in 6.5 Olympic-sized swimming pools." According to the real study found at the link below it says that damage was made to coral at 0.062 µg/L at the lower limit... That is 62000 ppt and 62 ppb. Can you guys please recheck the math? I've seen this stat in many publications and I'm concerned it's not correct... http://link.springer.com/article/10.1007%2Fs00244-015-0227-7
