The first time you buy fish fertilizer, the manufacturer says, it won’t hurt the fish.
But a new study says that even if you buy the right product, it can still have harmful effects.
In a new report, researchers found that the fertilizers they tested, and a second batch, all contained far more chemicals than the other batch.
Researchers found that all the chemicals found in fish fertilizer were present in concentrations that were more than 40 times higher than what’s considered safe.
And while fish fertilizer has long been used to combat the effects of fish bladder disease, researchers say that fish bladder toxin can also be used to kill fish.
The study looked at fish fertilizer from two manufacturers, Aquafina and the UK-based SPCA.
In addition to the chemicals, the researchers tested the fertilizer with several common drugs.
“We found that there was a very high level of toxins in the fish fertilizer that was very similar to what was found in the drugs used to treat bladder and intestinal disease,” says James Pardue, an associate professor of environmental science at Texas A&M University.
“We found a very large amount of toxic substances in the fertilizer, and we found the levels were very high.
So, you’re talking about very high levels of chemicals in a product that was used to control fish bladder,” he told ABC News.
Pardue says the chemicals can be dangerous if ingested.
“Fish bladder toxin is toxic in very large quantities,” he said.
“If the fish bladder has to be used, it’s going to have a very difficult time passing through the body, and that’s what happens in the bladder.”
In addition to toxin levels, Pardues team found that some of the chemicals in the second batch were very similar in some ways to the ones found in some of Aquafinas own products.
The chemicals that researchers tested in fish fertilizers were:Diazofuran, an industrial chemical that is used in a wide variety of industrial applications including paint and lubricantsDipropylene glycol, which is used to soften oil and greaseDiprofloxacin, which works as an insect repellentDiprazole, used to prevent bacterial growthDipterone, used in skin whitening productsDibutyl phthalate, a chemical used in plasticsDiazopropyl phthol, which contains an alcohol that is a carcinogenDipyridamole, a synthetic form of polysorbate 80 used to make plasticsDiethylhexyl phosphate, which can be used as a preservativeDiethylene glycoside, which washes off water to remove dirtDipropylamine, used as an anti-inflammatoryDipthalate propionate, used for cleaning solventsDipryloxacam, a commonly used preservative that helps prevent water from drying outDioxin, a pesticide used to disinfect waterDiethymethane, a compound used as disinfectantDiethylethanolamine, used primarily as an antifreezeDiphenylamine chloride, a common cleaning solventDiphenyltrimethoxazole, which uses benzene as a solventDiopropylpropionyl alcohol, used mainly for solvantsDiophenyl acetate, an antiseptic used as shampooDiprenorphine, which makes painkillersDipronidine, a pain relieverDiprone, used more commonly for hair dyeDiethydrofluorocarbon (DFF), a solvent used to form acetoneDiproxan, a cleaning solvent used in antisepticsDiprosthene, a solvent that can be mixed with a mixture of water and ammoniaDiprole, a disinfectant used to wash carpetsDiethylaniline (TED), a preservatives used to clean carpet floorsDiethyldimethyl sulfide (DEHP), a cleaning agent used to prepare carpetsIn all, researchers analyzed nearly 3,000 samples of fertilizer sold by both companies.
The researchers also looked at samples from Aquafinina’s own product line.
The company says it will take steps to remove some of these chemicals.
But even if Aquafins new product is found to be safe, it doesn’t mean you should stop buying it, Pardsue says.
“It’s a question of how much fish should you be buying for your tank,” he says.
“There’s a lot of information out there about what fish to feed, and there’s a little bit of a trade off between what’s in your tank and what’s not.”
