lead

According to both the American Veterinary Medical Association and the American Society for the Prevention of Cruelty to Animals, pets are more likely to exceed recommended levels of lead exposure through household contamination rather than by pet toys. Pets and children may be exposed to lead contained in consumer products like lead sinkers used to weigh down fishing lines, the consumption of old paint chips, linoleum, certain paints used by artists, or the inhalation of lead dust when surfaces of older homes are scraped or sanded.
