By now, most dogs have learned to scrub the floor, but one breed of dog that still suffers from the toxic legacy of the pesticides has a special need for a little extra help.
For centuries, people have used horse manure as the basis for a range of household products.
Horses have been a key ingredient in the creation of many different types of cosmetics, and horse manure is one of the most abundant sources of organic food in the world.
But horse manure contains a lot of chemicals, including pesticides and PCBs, that can cause health problems in humans.
In a new study published in the journal Environmental Science & Technology, a team of researchers from the University of Michigan and the University at Buffalo used a new type of analytical method to identify more than a dozen chemicals present in horse manure, including arsenic, PCBs and aflatoxin.
This is not the first time researchers have looked for chemicals in horse-based products.
Previous studies found chemicals in organic chicken and pork products.
The study used new analytical techniques to find out if there were chemicals in the horse manure.
Researchers then analyzed the chemicals in these organic products to see if they were the same as those in organic poultry, fish, and egg products.
They found no evidence of these chemicals in any of these organic ingredients.
They also tested the contents of organic dog treats to see whether they contained any chemicals that are inorganic.
They tested three different organic dog foods, and all three tested below the EU limit of 10 parts per billion of arsenic, but no traces of the same chemicals found in horse urine.
The researchers found no significant differences between the products when the organic and horse-derived ingredients were compared.
“These results suggest that horse urine has a much lower concentration of contaminants than organic dog products,” said lead author of the study, Michael M. Hildebrand, PhD. “If you’re a dog owner and you have a few horses in your home, you may want to avoid horse urine.”
Hildebrand is a senior lecturer in animal science at the University College London.
He is the lead author on a new paper about this study that was published in Environmental Science&TECH in June.
The study was funded by the National Science Foundation.
