And then what...?
If you stuff tampons into them, won't all the lakes & rivers just dry up?
A paper by a University of Sheffield research team, published Tuesday in the Water and Environmental Journal, has sought to answer one of the eternal questions facing humanity — how female hygiene products can be used to detect sewer misconnection discharge. Professor of Environmental Engineering David Lerner told The Register …

Wild guesses:
Almost everything contains fluorescors. Tampons might be one of the few things that don't.
The concentration in fluorescors in river water could be too low to detect with cheap equipment.
Washing powders include fluorescors to make your shirts look whiter. If the fluorescor simply rinsed out, it would not be of any use. I assume they include one that binds to cotton.
If my three guesses are correct, tampons concentrate fluorescors to the point where they become easily detectable with cheap portable equipment.
I imagine it's easier this way than taking samples for testing in the lab. Tampons don't cost much.
I can only assume they use tampons instead of cotton balls because they have a handy string for tying them to things.
Plus if they used cotton balls it wouldn't be in all the national newspapers. This has been done for ages by cavers wanting to find out if point A and point B are connected underwater: place some cotton balls at point B, tip some laundry detergent in at point A and go back with a UV light a few days later....

I'm not sure using Tampons for anything other than their original purpose is a good idea.
A few years ago I cut my head, it was bleeding profusely and wouldn't stop. After soaking through multiple tea towels a female friend took a sanitary pad from her bag and suggested I try it. It worked perfectly: the bleeding was controlled almost instantly.

Ah, the old chestnut that is the Glowing Tampon. Is there nothing that Glowing Tampons cannot be used for? Often these days, in very diverse applications, Glowing Tampons are the solution that scientists are turning to, again and again. Whatever the vexing question, it would appear that Glowing Tampons are the answer. People are smoking them, building houses out of them... They'll be eating them next.
Firefox isn't showing me the alt text, for some reason, but the image URL says it's Lock and Dam number 7 on the Mississippi River, not somewhere in the state of Mississippi. Wikipedia says L&D7 is on the Minnesota/Wisconsin border. Apparently it is just upstream from the I-90 Mississippi River bridge.
It has been the detector of choice for hydrologists studying the flows of cave water for years. We drop the optical brighteners in a stream in a cave and have tampons at all the possible outlets. We replace the 'sensors' at regular periods to find out which is the outflow and how long it took for the water to flow through (an indication of how much of the route has air spaces). - so many puns!
