What is Arsenic Concentrations, Diversity and Co-occurrence Patterns of Bacterial and Fungal Communities in the Feces of Mice Under Sub-chronic Arsenic Exposure Through Food about?
## Background: Arsenic, a global pollutant and a threshold-free primary carcinogen, can accumulate in rice. previous studies have focused on arsenic poisoning in drinking water and the effects on gut microbes. the research on arseniasis through food, which involves the bio-transformation of arsenic, and the related changes in gut microbiome is insufficient. ## Method: Mice were exposed from animal feed prepared with four arsenic species (ias, ias, mma, and dma) at a dose of 30 mg/kg according to the arsenic species proportion in rice for 30 days and 60 days. the levels of total arsenic (tas) and arsenic species in mice feces and urine samples were determined using icp-ms and hplc-icp-ms, respectively. 16s rrna and its gene sequencing were conducted on microbial dna extracted from the feces samples. ## Results: At 30 days and 60 days exposure, the tas levels excreted from urine were 0.0092 and 0.0093 mg/day, and tas levels in feces were 0.0441 and 0.0409 mg/day, respectively. we found significant differences in arsenic species distribution in urine and feces (p < 0.05). in urine, the predominant arsenic species were ias (23% and 14%, respectively), dma (55% and 70%, respectively), a
