Sep 15, 2012A survey of soil profiles covering 26 countries in Europe gave a median arsenic concentration of 7.03 mg kg −1 in topsoils (840 samples) and 6.02 mg kg −1 in subsoils (783 samples) (FOREGS, 2005). Concentrations of 1000 mg kg −1 or more have been found at contaminated sites close to smelters or industrial sites (Lumsdon et al., 2001).

Ironstone Wikipedia

Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron compound from which iron can be smelted commercially. This term is customarily restricted to hard coarsely banded, nonbanded, and noncherty sedimentary rocks of post-Precambrian age.. The Precambrian deposits, which have a

What is Iron stone? What is uses of iron stone?

Ironstone is a form of sedimentary rock that has a wide variety of commercial and consumer uses. Sedimentary rocks are formed by the gradual accumulation of sand or other small particles over time. Eventually the compacted particles are turned to stone by a combination of heat and pressure. In the case of ironstone, the particles
