Long-Term Atmosphere Surveillance (2016-2021) of PM-bound Polycyclic Aromatic Hydrocarbons and Health Risk Assessment in Yangtze River Delta, China.

Unlabelled: Long-term atmospheric quality monitoring of fine particulate matter (PM) and PM-bound polycyclic aromatic hydrocarbons (PAHs) was performed in Wuxi from 2016 to 2021. In total, 504 atmospheric PM samples were collected, and PM-bound 16 PAHs were detected. The PM and ∑PAHs level decreased annually from 2016 to 2021, from 64.

Surveillance of long-term environmental elements and PM health risk assessment in Yangtze River Delta, China, from 2016 to 2020.

PM metal pollution significantly harms human health. The air quality in Wuxi is poor, especially in winter, and long-term monitoring of PM elements comprising has not been performed previously. In the present study, 420 PM samples were collected from January 2016 to December 2020.

Drinking water elements constituent profiles and health risk assessment in Wuxi, China.

Water elements pollution has attracted public attention globally. Wuxi is located in East China, and its water source, Taihu Lake, has been severely polluted since 2007. Studies of elemental pollution profiles have yet to be conducted in this area.

Determination of 10 Haloacetamides in drinking water by gas chromatography with automated solid phase extraction.

Drinking water disinfection may result in the formation of different classes of toxic disinfection by-products (DBPs). Haloacetamides (HAcAms) are an emerging class of nitrogenous DBPs (N-DBPs), which are generally more prevalent at lower concentrations in disinfected water than carbonaceous DBPs. Herein a fast, convenient, and effective method of analyzing 10 HAcAms in drinking water samples was demonstrated.

Investigating the adsorption behavior and quantitative contribution of Pb adsorption mechanisms on biochars by different feedstocks from a fluidized bed pyrolysis system.

The aim of this study was to examine the qualitative and quantitative analysis of Pb adsorption mechanisms performed with biochars derived from rice straw (RSBs), rice husk (RHBs) and saw dust (SDBs) at several pyrolysis temperatures (400-600 °C) in a fluidized bed system. Adsorption isotherms, kinetics, and desorption analysis were determined, and biochars were analyzed by X-ray Photoelectron Spectroscopy (XPS), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscope with Energy Dispersive Spectrometer (SEM-EDS) and Boehm titration method. The effect of minerals on Pb adsorption, including precipitation and cation exchange, revealed increasing contribution of precipitation from a range of 4.

A novel CdSe/CdS quantum dot-based competitive fluoroimmunoassay for the detection of clenbuterol residue in pig urine using magnetic core/shell Fe3O4/Au nanoparticles as a solid carrier.

Quantum dots (QDs) are semiconductor fluorescent nanoparticles, which can be used for food safety or environmental monitoring with high sensitivity. This work demonstrates the feasibility of detecting clenuterol residue in pig urine using CdSe/CdS quantum dots as fluorescent labels based magnetic core/shell Fe3O4/Au nanoparticles (MCFN) as solid carriers. The detection of clenbuterol is carried out by a fluoroimmunoassay-based biosensor using competitive binding between conjugated clenbuterol antigen-CdSe/CdS QDs and free clenbuterol with immobilized clenbuterol antibodies on MCFN.
