Article Synopsis
  • Heavy metal pollution in urban river sediments poses a significant threat to ecosystem health; a study conducted in Kaifeng City compared sediment samples from 2015 and 2021 to evaluate this issue.
  • Results showed a notable decrease in heavy metal concentrations—Cd, Cr, Cu, Ni, Pb, and Zn dropped significantly, with Cd showing the largest reduction.
  • Despite improvements, heavy metal levels, especially in the Huafei and Huiji Rivers, remain concerning, indicating a need for ongoing monitoring and targeted pollution control efforts.

Background: In recent years, the goal of universal coverage of the basic medical insurance schemes has been basically achieved in China, but the heavy economic burden of diseases is still the main cause of poverty in many households. Exploring catastrophic health expenditure (CHE) and its inequality are highly important for forward-looking policymaking. This study aims to compare the incidence, intensity and inequality of CHE between urban and rural households in China.

Background: After achieving universal basic medical insurance coverage, Chinese government put the development of private health insurance (PHI) on its agenda to further strengthen financial risk protection. This paper aims to assess the level of financial protection that PHI provides for its insured households on the basis of resident basic medical insurance (RBMI).

Methods: We employed balanced panel data collected between 2015 and 2017 from the China Household Finance Survey (CHFS).

Background: The prevalence of chronic non-communicable diseases (NCDs) challenges the Chinese health system reform. Little is known for the differences in catastrophic health expenditure (CHE) between urban and rural households with NCD patients. This study aims to measure the differences above and quantify the contribution of each variable in explaining the urban-rural differences.

Background: Aging and the chronic non-communicable diseases (NCDs) challenge the Chinese government in the process of providing hospitalization services fairly and reasonably. The Chinese government has developed the basic medical insurance system to solve the problem of "expensive medical cost and difficult medical services" for vulnerable groups and alleviate the unfair phenomenon. However, few studies have confirmed its effect through longitudinal comparison.

The present paper reports photocatalytic degradation of bovine serum albumin (BSA) by TiO2 under near UV (365 nm) irradiation. Ultraviolet-Visible spectrometry, FTIR spectrometry and HPLC were used to study the degradation and characterize the final degradation products. It was found that under near UV irradiation, BSA (0.

The TiO2 membranes were prepared on glass, ceramic tile and aluminum pieces by Sol-Gel and PVD methods. A fast and exact evaluation on the photocatalytic self-cleaning performance of the membrane materials was achieved by FTIR-ATR technique using oleic acid which was laid on the surface of the membrane. The hydrophilic property of the samples was also determined by the contact angle with water.

Disinfection with photocatalysis, compared to with the conventional cleanout, is both high efficient and non contaminative, but the simple TiO2 photocatalyst is showing to be of low activity and low active stability so to be hardly practical application. In the paper, SO4(2-)/TiO2 were papered by surface modification of TiO2 with dilute H2SO4, and the photocatalytic degradation of 2-chloroethyl ethyl sulfide (2-CEES) on the samples was examined in a fixed-bed microreactor. The examination show that the acidic modification enhanced both the activity and the active stability of TiO2, and the sample ST200 prepared by calcination at 200 degrees C was better than ST400 by calcination at 400 degrees C.

MCM-41 modified with tetrabutyltin and Sn-O-MCM-41 obtained from calcination of the modified MCM-41 in pure oxygen were characterized by XRD, FTIR, UV-Vis DRS, and TG analysis. It was found that the hydrothermal stability, surface acidity, and coordinative states of tin atoms on both samples were evidently different. After calcination, the surface tin atoms of sample remained in the tetrahedronal structure, and the hydrothermal stability and surface acidity were improved.

Photocatalytic ceramic was prepared by coating photocatalytic membrane on ceramic matrix. The photocatalytic behavior of the TiO2 coated ceramic for degradation of oleic acid, ethylene, SO2, NOx and sterilization was studied by using XRD, chromatogram, in-situ IR and spectrophotometer. The results showed that the photocatalytic ceramic prepared by special conditions have the function of environmental conservation such as the photodegradating organic contaminants, removing inorganic baleful gas and killing bacteria.
