TLDR
In this paper, the roles of microbial activities in the accumulation of iodine in soils and its loss from soils were studied, and concentrations of stable iodine in several type of soils were determined by inductively coupled plasma-mass spectroscopy.Abstract:
The roles of microbial activities in the accumulation of iodine in soils and its loss from soils were studied. Concentrations of stable iodine in several type of soils were determined by inductively coupled plasma-mass spectroscopy. High iodine concentrations were found in upland soils, particularly in Andosol, whereas the concentrations in lowland soils were considerably lower. Accumulation of iodine in soils was explained by the effects of microorganisms or their products (e.g., enzymes), or both. Iodine was observed to be desorbed from the flooded soils because of the reducing conditions (low Eh) created by the microbial activities. Evaporation of biogenerated methyl iodide from the soilplant system, specifically from rice plants, may also decrease the iodine concentrations in lowland soils.read more

Iodine and human health, the role of environmental geochemistry and diet, a review
TL;DR: Iodine is an essential element in the human diet and a deficiency can lead to a number of health outcomes collectively termed iodine deficiency disorders (IDD) as mentioned in this paper, however, the major zone of marine influence generally stretches to only 50-80 km inland and terrestrial sources of volatilised iodine, from wetlands, soils and plants are also an important aspect of its global geochemical cycle.

The role of microorganisms in gold processing and recovery—A review
TL;DR: A review of the role of microorganisms in gold processing and recovery can be found in this paper, which covers aspects such as the biotechnical pre-treatment of gold ores and concentrates, microbially catalysed permeability enhancement of ore bodies, gold solubilisation through biooxidation and complexation with biogenic lixiviants, and micro-bially mediated gold recovery and loss from leach liquors.
