“…attributed the presence of Sc and other REE in dry commercial dog food to soil particle impurities and the addition of non‐purified mineral ingredients. Phosphates, which can have high concentrations of REE impurities, are used as a source of P in dry dog food . Table S3 also shows an association of REE with insecticide use, although no intentional use of REE in insecticides could be found in the literature (again, this association may be related to REE impurities in phosphates).…”

“…Another difference in elemental signatures associated with dogs vs cats is the stronger correlation for Sc with dogs ( r s =.28; P <.001) compared to cats ( r s =.08; P =.015), which also may reflect differences in pet products associated with each group. Elias et al . attributed the presence of Sc and other REE in dry commercial dog food to soil particle impurities and the addition of non‐purified mineral ingredients.…”

Rare earth elements and select actinoids in the Canadian House Dust Study

Nationally representative baseline data are presented for rare earth elements (REE), thorium (Th) and uranium (U) in house dust sampled from 1025 urban homes, in units of concentrations (μg g ), loadings (μg m ), and loading rates (ng m d ). Spearman rank correlations indicate that, in addition to outdoor sources, consumer products and building materials can influence indoor dust concentrations of REE, Th, and U. Correlations (P<.01) with numbers of occupants, dogs, and cats suggest soil track-in. Correlations (P<.01) with hardwood floors suggest release of REE additives used in pigments and coatings during daily wear and tear. Concentrations of light REE are elevated in smokers' homes compared to non-smokers' homes (P<.001), suggesting that a key source is "mischmetal," the REE alloy used in cigarette-lighter flints. Indoor sources include geological impurities in raw materials used in consumer products, such as U and Th impurities in bentonite clay used in cat litter, and REE impurities in phosphates used for a variety of applications including dog food and building materials. Median gastric bioaccessibility (pH 1.5) of most REE in dust ranges from about 20% to 29%. Household vacuum samples correlate with fresh dust samples from the same homes (P<.001 for all investigated elements).

“…Literature data showed uranium values in pet food (n = 58) ranging from 0.78 mg/kg to 0.86 mg/kg (Atkins et al 2011). In another study of dry dog food (Elias et al, 2012) uranium was found at levels as high as 4 mg/kg in some of the 34 samples analyzed.…”

“…The global feed industry for dogs and cats has grown extensively, particularly in Brazil, which occupies the second place in cat and dog feed production behind the United States. [1][2][3] Various types of feed are available in the market, and they can be differentiated according to the ingredients, size and breed of the animal, and for animals predisposed to a specific disease. [2][3][4] Dry feeds should present a final humidity between 10 and 12% 5 and be formulated to achieve a specific amount of nutrients, using as raw material cereal grains and products derived from animal sources.…”
