Magnetic properties of tree leaves and their significance in atmospheric particle pollution in Linfen City, China

Distribution of magnetic remanence carriers in the human brain

“…Once cut, each specimen was placed into a sterile vessel, weighed, and transported to a magnetically shielded room (~200 nT ≈ < 0.5% of the Earth’s ambient field) situated in a forest, 80 km northeast of Munich, that houses a three-axis, superconducting magnetometer (bore diameter = 7.6 cm) (2G Enterprises Inc., Mountain View, CA, USA). This laboratory has the advantage of avoiding anthropogenic magnetic pollution pervasive in urban environments 10 . After the first three brains were measured, the shielded room was converted to a clean room complete with a high efficiency particulate air (HEPA) filter and electromagnetic filtered air; no systematic difference in magnetization characteristics (average intensity, etc.)…”

Atmospheric pollution history at Linfen (China) uncovered by magnetic and chemical parameters of sediments from a water reservoir

“…In order to alleviate the environmental pressure, the local government implemented a series of measures during the last decade to improve the air quality, and in fact the atmospheric environmental conditions have improved significantly since then (Report on the State of the Environment in Shanxi Province, 2000e2013). Previous studies mainly used the magnetic properties of tree leaves (Yin et al, 2013), soils and dust falls (submitted) to monitor the pollution status at Linfen city. There are several water reservoirs in Linfen area, which supplies the possibility to use magnetic parameters of continuous sediments for reconstructing the pollution history.…”

An economic passive sampling method to detect particulate pollutants using magnetic measurements

“…Yin et al (2013) have presented a study of magnetic susceptibility of a widespread leaf species (Juniperus Chinensis) in Linfen urban area. We meanwhile extended this work to a larger area using the same methodology.…”
