For residential combustion sources, we assumed that the mobile source intake fraction estimates were applicable (given emissions at or near ground level) and calculated intake fractions for each Metropolitan Statistical Area (MSA) across the US.
Mobile source intake fractions may not be identical to residential intake fractions, and the values applied may be underestimates, given the importance of near-source impacts and the relatively low geographic resolution of models underlying our intake fraction estimates [ 22].
"Zhou and Levy point out that in urban street canyons mobile source intake fractions may be two to three orders of magnitude larger than in suburban and rural areas.
We observed an increased risk of total RCC among participants in the highest quintile of nitrite from animal sources intake compared with those in the lowest quintile (HR=1.28, 95% CI, 1.10 1.49) with a significant positive trend (P-trend<0.01).
Further evidence is nevertheless needed to elucidate the interrelationships among arsenic exposures from multiple sources, intake of various types of rice grains, and CVD risk, as well as other disease outcomes.
Population differences in dietary sources, intake levels, and mineral balances may explain why an American study [ 7] reported a negative association and we conversely detected a positive association, both of borderline statistical significance, between dietary phosphorus and bladder cancer.
Moreover, several genes involved in nitrogen sources intake and assimilation were inhibited in E3 strain, including the oligopeptide transporter operons (SACE_0257-0260, Samino844-0848), acido acid transporter operon (SACE_6266-6269), glutransporterspoperonoperon (SACE_1743-1746), glutransporterspoperonoperon (SACE_7284-7286), ammoniumnium transporter gene (amt, SACE_6062).

The main advantages of this water source were: intake and infrastructure already available: reduces costs for feed water intake; high temperature seawater: reduced seawater RO feed pressure; abundant availability: higher reliability.
Urine pH, blood pH and blood HCO 3− concentrations were significantly lower for horses consuming diets with a low DCAD as compared with high DCAD diets regardless of starch source or intake.
Alcohol consumption was assessed using questionnaire designed to determine long-term (at least for a last year and extending back to several years), frequency, amount, and source of intake, with the help of the same dietitian.
