Fluorescent characteristic and compositional change of dissolved organic matter and its effect on heavy metal distribution in composting leachates.

Composting leachates were collected to investigate the fluorescent characteristic and compositional change of dissolved organic matter (DOM) and the effects of the DOM and nutrients on heavy metal distribution during a leachate combination treatment process. Excitation-emission matrix (EEM) fluorescence spectra showed that, with the progress of the treatment units, the content of fulvic-like, humic-like, and protein-like substances gradually decreased. One fulvic-like component (C1), three humic-like components (C2, C3, and C4), and three protein-like components (C5, C6, and C7) were identified in the leachate DOM by parallel factor analysis.

Photocatalytic disinfection performance in virus and virus/bacteria system by Cu-TiO nanofibers under visible light.

The presence of pathogenic microorganisms in water is a great threat to human health, and photocatalysis is promising for disinfection. However, the research on virus inactivation with visible-light photocatalysis is still limited, especially the coexistence of virus and its host bacteria. In this study, bacteriophage f2 and its host E.

Insights into the pollutant-removal performance and DOM characteristics of stormwater runoff during grassy-swales treatment.

The water purification performance of grassy swales for treating stormwater road runoff was evaluated using a simulated experimental device in two different seasons. The results showed that the removal rates for total suspended solids (TSS), chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP) reached 89.90%, 56.

Detection of Copper (II) and Cadmium (II) binding to dissolved organic matter from macrophyte decomposition by fluorescence excitation-emission matrix spectra combined with parallel factor analysis.

Fluorescence excitation-emission matrix (EEM) spectra coupled with parallel factor analysis (PARAFAC) was used to characterize dissolved organic matter (DOM) derived from macrophyte decomposition, and to study its complexation with Cu (II) and Cd (II). Both the protein-like and the humic-like components showed a marked quenching effect by Cu (II). Negligible quenching effects were found for Cd (II) by components 1, 5 and 6.

Prevalence of and risk factors for the occurrence of symptomatic osteoarthritis in rural regions of Shanxi Province, China.

Aim: To determine the prevalence of symptomatic osteoarthritis (OA) in rural regions of Shanxi Province, China, and to identify factors increasing the prevalence of OA.

Method: Residents over 16 years of age of targeted towns and villages in rural regions of Shanxi Province were sampled using a stratified multi-stage cluster method. Those exhibiting symptoms of rheumatism were referred to rheumatologists and those in whom rheumatism was suspected were X-rayed within 10 days of interview.

Detection of dissolved organic matter in saline-alkali soils using synchronous fluorescence spectroscopy and principal component analysis.

Dissolved organic matter (DOM) is attributed a key role in soil major biogeochemical processes. Its molecular characteristics can reflect both its source and its biogeochemical history. Saline-alkali soil samples were collected from a field in desert and semi-desert region.

[Speciation and vertical distribution of heavy metals in sediments of Baiyangdian Lake].

In order to find out the heavy metal concentrations and their potential ecological risks on sediments in Baiyangdian Lake, 0-14 cm surface sediments had been collected by the no-disturbance-gravity sampler at seven representative sampling points of Baiyangdian Lake. Optimized BCR sequential extraction procedure was used to carry out the analysis of heavy metal forms in the surface sediments. The heavy metal contents of different forms and in different depths were determined.

Spectroscopic techniques for quantitative characterization of Cu (II) and Hg (II) complexation by dissolved organic matter from lake sediment in arid and semi-arid region.

Dissolved organic matter (DOM) was extracted from six sediment samples in arid and semi-arid region, which was characterized by fluorescence excitation-emission matrices (EEMs). The results showed that four fluorescent peak, fulvic-like (peak A), humic-like (peak C) and two tryptophan-like (peaks B and D), were identified in lake sediment DOM. Fluorescence quenching titration showed that peaks B and D were quenched gradually by adding additional Cu (II) and Hg (II), whereas humic-like substances had no systematic trend of the change of fluorescence intensity.

Epidemiologic study of soft tissue rheumatism in Shantou and Taiyuan, China.

Background: Soft tissue rheumatism is a group of common rheumatic disorders reported in many countries. For investigating the prevalence rate of soft tissue rheumatism in different population in China, we carried out a population study in Shantou rural and Taiyuan urban area.

Methods: Samples of 3915 adults in an urban area of Taiyuan, Shanxi Province, and 2350 in a rural area of Shantou, Guangdong Province were surveyed.

[A cross-sectional population survey of knee osteoarthritis in Taiyuan region].

Objective: Osteoarthritis (OA) of the knee is found to be one of the commonest rheumatic disorders. For prevention of knee OA, the risk factors for this condition should first be identified.

Methods: A population sample of 2188 adults aged 35 - 64 years, living in 6-story buildings without elevators, was surveyed from April to August 2005 in the urban of Taiyuan region, north China.

Associated risk factors of knee osteoarthritis: a population survey in Taiyuan, China.

Background: Since knee osteoarthritis (KOA) is one of the common diseases, identification of its associated risk factors is of preventive significance. This investigation was designed to investigate the prevalence of KOA in Taiyuan, and identify the associated risk factors of KOA.

Methods: A population sample was surveyed of 2188 adults aged from 35 to 64 years, living in 6-story buildings without elevators.

[Analysis on the removal efficiency of phosphorus in some substrates used in constructed wetland systems].

Constructed wetlands are widely used to purify wastewater in some developing countries. As filter substrates in such wetland, these substrates play important role on removal of pollutants from wastewater. Selecting suitable substrates is one of the effective ways to improve the performance of constructed wetland on treating wastewater.
