...Published in Chemosphere
To investigate the cross-sectional and longitudinal associations between aluminum exposure and lung function and the risk of chronic obstructive pulmonary disease (COPD). The repeated-measure study was developed with 3917 adults from the Wuhan-Zhuhai cohort and they were followed-up after 3 years and 6 years. Urinary aluminum and lung function were...
Performance and operational strategy of simultaneous nitrification, denitrification, and phosphorus removal system under...
Published in Chemosphere
A pilot-scale aerobic granular sequencing batch reactor (SBR) with domestic wastewater was operated to evaluate the effects of the low organic loading rate (OLR) due to wet weather flow conditions on simultaneous nitrification, denitrification, and phosphorus removal (SNDPR). As the OLR decreased from 0.85 to 0.43 kg COD m-3 d-1, the total nitrogen...
Spectrophotometric determination of hydrogen peroxide in water with peroxidase-catalyzed oxidation of potassium iodide a...
Published in Chemosphere
A spectrophotometric method for the rapid measurement of hydrogen peroxide (H2O2) in aqueous solutions was developed in this study. This method is based on a reaction catalyzed by peroxidase (POD) in which potassium iodide (KI) is oxidized to generate the stable yellow-colored I3- within 15 s. The absorbance of the generated I3- at both 350 nm and ...
Coordinated control of PM2.5 and O3 is urgently needed in China after implementation of the "Air pollution prevention an...
Published in Chemosphere
To improve air quality, China formulated the Air Pollution Prevention and Control Action Plan (APPCAP) in 2013. In the present study, the changes in the concentration of air pollutants after the implementation of APPCAP were investigated based on nationwide monitoring data. From the results, it is evident that the annual mean concentrations of PM2....
Spiromesifen induces histopathological and cytotoxic changes in the midgut of the honeybee Apis mellifera (Hymenoptera: ...
Published in Chemosphere
The honeybee Apis mellifera is an important pollinator that, similarly to other bees, undergoes colony losses due to several problems, including the use of pesticides in the agriculture. In addition to direct mortality, pesticides cause side-effects in some non-target organs, such as the midgut, which is the main organ for digestion and absorption....
Dietary exposure to polyethylene terephthalate microplastics (PET-MPs) induces faster growth but not oxidative stress in...
Published in Chemosphere
Polyethylene terephthalate (PET) is one of the main plastic polymers contaminating natural ecosystems. Although PET microplastics (PET-MPs) have been found in both aquatic and terrestrial ecosystems, the information concerning their potential toxicity towards terrestrial organisms is limited. The present study aimed at investigating the ingestion a...
Facile fabrication of a conductive polypyrrole membrane for anti-fouling enhancement by electrical repulsion and in situ...
Published in Chemosphere
Conductive membranes provide a promising method to alleviate membrane fouling, but their cost-effective fabrication, which is urgently needed, is still a challenge. This paper describes the facile fabrication of an ultrafiltration conductive polypyrrole (PPy)-modified membrane (PMM) by in situ chemical polymerization of FeCl3 and monomer pyrrole va...

Published in Chemosphere
In this work, a novel ternary Fe3O4/[email protected] composite was fabricated using iron-doped copper 1,4-benzenedicarboxylate metal-organic frameworks as a self-sacrificing template. The morphological, structural, and optical properties of the prepared composite were determined by various techniques, and its photocatalytic behavior was investigated for degra...
Toxicokinetics of copper and cadmium in the soil model Enchytraeus crypticus (Oligochaeta).
Published in Chemosphere
Toxicokinetics information is key to understanding the underlying intoxication processes, although this is often lacking. Hence, in the present study the toxicokinetics of copper (Cu) and cadmium (Cd) was assessed in the soil invertebrate Enchytraeus crypticus. The animals were exposed in LUFA 2.2 natural soil spiked to the estimated EC20 for repro...
