TL;DR: It is shown that perchlorate is readily formed by a variety of simulated atmospheric processes, and is present in many rain and snow samples, which strongly suggests that some per chlorate is formed in the atmosphere and a naturalperchlorate background of atmospheric origin should exist.

TL;DR: On the basis of limited available data, iodide levels in breast milk may be significantly lower than it was two decades ago and recommended iodine intake by pregnant and lactating women may need to be revised upward.

TL;DR: An ion chromatography-ion association-electrospray ionization-mass spectrometry (IC/IA-ESI-MS) method of substantially greater selectivity and sensitivity than other available single-stage MS approaches is reported here.

TL;DR: Although most seaweed samples contain some amount of perchlorate, the great majority contains iodide in so much higher amount that at least for the commonly used Laminaria species, the iodide/perchlorate ratio is greater than the square of the per chlorate to iodide selectivity factor reported for the mammalian NIS and should thus lead to net beneficial iodine nutrition even in a two-stage mother-infant scenario.

TL;DR: In this article, a significant amount of particulate H 2 Ox/oxalate (Ox) occurred in the coarse particle fraction of a dichotomous sampler, the ratio of oxalate concentrations in the PM 10 to PM 2.5 fractions ranged from 1 to 2, with mean±sd being 1.4±0.2.
