These materials possessing low inorganic contents, high carbon contents, as well as various functional groups have high affinity for pollutants uptakes.
Pb contents high in impaired sites group can be related to urban runoff, traffic density, and automobile washing which is common along stream banks.
Results show that WPCs with high fiber contents, high moisture contents, and low polymer tensile strengths are most susceptible to frost-induced damage.
They are all characterized by very high Sr and low Y Yb contents, high Sr/Y and (La/Yb N ratios, similar ƐNd(t) values from − 18.2 to − 21.4, and similar initial 87Sr/86Sr ratios from 0.7076 to 0.7119.
These highly porous catalysts have adjustable pyridine contents, high BET surface area (312 649 m2/g), large pore volume (0.5 2.0 cm3/g) and rapid swelling property, thus they efficiently combined the advantage of both homogeneous and heterogeneous catalysts.
The cores exhibit clearly oscillatory or patchy zonation, high trace element contents, high Th/U ratios of 0.13 to 2.12, steep MREE HREE patterns, and significant negative Eu anomalies.
