TL;DR: It is shown that the widely used herbicide, atrazine, was the best predictor of the abundance of larval trematodes in the declining northern leopard frog Rana pipiens, and analysis of field data supported a causal mechanism whereby both agrochemicals increase exposure and susceptibility to larval Trematodes by augmenting snail intermediate hosts and suppressing amphibian immunity.

TL;DR: The case for atrazine as an endocrine disruptor that demasculinizes and feminizes male vertebrates meets all nine of the "Hill criteria" for establishing cause-effect relationships.
Journal ArticleDOI
Alteration of Tissue and Serum Sphinganine to Sphingosine Ratio: An Early Biomarker of Exposure to Fumonisin-Containing Feeds in Pigs

TL;DR: The results of this study show that free sphinganine is elevated in liver, lung, and kidney, from pigs consuming feeds containing fumonisin concentrations of 23 ppm or greater, and this supports the hypothesis that inhibition of sphingosine and sphingAnine N-acyltransferase plays an important role in the pathogenesis of animal diseases associated with consumption of feed containing fUMonisins.
