As a primary sink of pollutants, urban soil heavy metal pollution and its influence on residents ecosystems has been becoming one the most important environmental problems. In present study, four indices, Geoaccumulation index (Igeo), improved Nemerow (IMN), degree contamination (mCd), security (CSI), as well potential ecological risk (RI), were used to evaluate individual or integrated for samples collected from city parks, vicinity landfill, an industrial area within Guangzhou. The results...
Abstract Widespread geological preservation of biogenic magnetite makes it important to assess how such particles contribute sedimentary paleomagnetic signals. We studied a sediment core from the South China Sea that passes strict empirical criteria for magnetic “uniformity” used in relative paleointensity studies. Such assessments are based routinely on bulk parameters often fail enable identification mixed mineral assemblages. Using techniques component‐specific identification, we find and...
During the past decades, heavy metal pollution in agricultural soil and its impact on human health have been becoming one of most important global environmental problems. In this research, (Cu, Pb, Zn, Cr, Cd, Ni, As, Hg) concentrations were measured for four hundred two samples collected from area within Guangzhou-Foshan urban zone. Soil was evaluated used geoaccumulation index potential ecological risk index. The dose response model proposed by USEPA to estimate caused metals soil. results...
Similar to loess-paleosol sequences in northwestern China, terrestrial sedimentary (red soils) southern China also provide sensitive Quaternary records of subtropical/tropical paleoclimate and paleoenvironment. Compared with red clay originated from eolian dust, soils derived bedrock have received little attention. In this study, a long core soil weathered basalt northern Hainan Island, was systematically investigated by using detailed magnetic measurements rare earth element analyses. The...
Abstract The Red River is located at the intersection of Indian and East Asian monsoons. Understanding evolution history monsoon in basin helps to comprehend Summer Monsoon. Herein, we present high‐resolution major elements Sr‐Nd isotopic ratios terrigenous sediment component for a well‐dated core retrieved from northern South China Sea slope, aiming identify provenance reconstruct silicate chemical weathering intensity since past 36 kyr. was confirmed as source through ratios. affected by...
A composite Holocene sediment profile ∽5 m in length, constrained by both radiocarbon dating and magnetic susceptibility based correlation, was obtained from three Livingstone piston cores collected ∽10-m water depth the Huguangyan (HGY) maar lake, southern China. The homogeneous silty clay indicates stable continuous deposition. dominant carrier is magnetite pseudo-single-domain grain size range thus suitable for recording palaeomagnetic secular variations (PSV). Results show that HGY PSV...
Abstract South China Sea (SCS) sediments can provide important paleoclimate records because of their generally high deposition rates and strong regional influence East Asian summer monsoon (EASM) variations. However, interpretation sedimentary from the northwestern SCS slope is complicated sedimentation sensitive to sea level provenance We seek develop a paleoclimatic record by analyzing sediment magnetic properties over past ∼36 kyr core PC338. The dominant minerals are magnetite hematite...
