Polyaniline-coated core-shell silica microspheres-based dispersive-solid phase extraction for detection of benzophenone-type UV filters in environmental water samples. Polyaniline-modified core-shell mesoporous silica (CSMS@PANI) nanocomposite microspheres are synthesized as adsorbent in dispersion-solid phase extraction (d-SPE) for enrichment and purification of benzophenone-type UV filters. The synthesized CSMS@PANI nanocomposite microspheres exhibit large specific surface area (33.45 m 2 /g) and uniform fibrous shell (microsphere...

Azo dye pollutants Mineralization Microaerophilic consortia Lake sediment bacteria. Degradation metabolite analysis of MO and CR experiments by liquid chromatography-mass spectrometry (LC-MS) indicated that both dyes were catabolised into simpler com- pounds. Molecular phylogeny of several bacterial isolates from the experiments indicated that individual bacterial isolates possessed MO and CR degradation capability. Azo class dyes are known to be among...

Ultimate fate and toxicological consequences of insecticide pyriproxyfen and its metabolites in soil ecosystem. We studied metabolic pathway of PYR by observing dissipation behavior of different metabolites in soil under sub-tropical agro-climatic conditions of north India. Most metabolites appeared very early and attained maximum concentration on day one of PYR application. Summary: Degradation of pyriproxyfen revealed 6 metabolites most of...

Due to the Covid-19 pandemic, the use of disposable face masks has been adopted worldwide as a precautionary measure to slow down the transmission of the virus. This has determined an unprecedented rise in the production of these protective equipments, and unfortunately to a new form of environmental contamination due to the improper disposal. To provide a preliminary estimation of...

Fungi play a key role in the soil ecosystem, where they occupy the first level of the food chain. Among environmental pollutants, phenolic compounds and metal cations require special attention, since they occur in many different products/processes and are released on a massive scale in into the environment, causing highly negative impacts, especially to the bio- sphere ( Arjoon et...

A preliminary study on the detection of potential contaminants in the European brown hare ( Lepus europaeus ) by suspect and microplastics screening. Interestingly, POEAs had only been found in the wild hares investigated. Remarkable, numerous microplastic particles were detected in the lymph nodes of one wild brown hare from Pellworm. Results from long-term pathological examination conducted at the Research...
