The dry mass fraction of Cl org in surface soils (0.01–0.5%) is in parity with that of phosphorous (0.03–0.2%) and only slightly lower than nitrogen (1–5%) and sulphur (0.1–1.5%). Bulk density, horizon thicknesses and stoniness affect total storage of Cl more than concentration differences.
1 Δεκ 2001 · Abstract. Natural inputs of chlorine (Cl) to soils come mainly from rainwater, sea spray, dust and air pollution. In addition, human practices, such as irrigation and fertilization, contribute significantly to Cl deposition. In the soil solution, Cl occurs predominantly as the chloride anion (Cl −).
Runoff of organic chlorine from the lower layers of soil is about 0.01 g/m2yr, much smaller than from the top layer (0.2 g/m2yr). In fact, the concentration of organic chlorine decreases with depth as shown in Figure 3 for Skullebo (south of Linköping, S) and Klosterhede (DK). Figure 3.
30 Δεκ 2020 · In this study, a novel method using water extraction coupled with concatenated ion exchange chromatography for the extraction of hydrosoluble chlorine in soil samples is established for the determination of chorine isotopes by thermal ionization mass spectrometry.
20 Ιουλ 2023 · The results can explain why local soil chlorine levels are frequently independent of atm. deposition, and provide opportunities for improved modeling of chlorine distribution and cycling in terrestrial ecosystems.
26 Ιουλ 2005 · The origin of the chloride and organic chlorine in soil is considered and major sinks and sources are pin-pointed and estimated. Processes causing formation of organic chlorine (consumption...
1 Ιαν 2019 · The concentration of chloride (Cl −) in the soil depends on many factors: (i) the underlying parent bedrock material, (ii) depositions of airborne Cl − (iii) depositions through irrigation water, (iv) inputs via fertilization and other human activities, (v) contributions from basin brines or saline springs (Xu et al., 2000) or (vi) pumping-induc...
