"Metaldehyde Slug Bait - How Dangerous is it in the Garden? by Bill Meyer" angående hur giftigt snigelmedel med metaldehyd är:
“It is toxic to all mammals and birds, but not to aquatic life. Breakdown in the environment is rapid.
The average amount necessary to be fatal for a dog is somewhat variable, with the lowest being 100mg/kg, or 100 milligrams per kilogram of dog weight. This would roughly be a tablespoon of bait for the average dog. For cats, twice the amount per kilogram of body weight. Cats in general do not have excessive interest in the bait products, so are not considered to be very much at risk. Dogs are likely to remain at risk because of their interest in eating almost anything edible, but the most danger to them lies in improper use and storage rather than from areas in the garden where it has been properly applied.
Because of concern over poisoning from what could be an attractive bait, makers of slug baits containing metaldehyde were required to include denatonium benzoate, commonly known as Bitrex, the most bitter-tasting substance in the world. The amount of Bitrex was upped from 30ppm to 300ppm in late 2003, a tenfold increase, to help further reduce the number of poisonings.”
