Activated carbon was prepared from coirpith by a chemical activation method and characterized. The adsorption of toxic heavy metals, Hg(II), Pb(II), Cd(II), Ni(II), and Cu(II) was studied using synthetic solutions and was reported elsewhere. In the present work the adsorption of toxic heavy metals from industrial wastewaters onto coirpith carbon was studied. The percent adsorption increased with increase in pH from 2 to 6 and remained constant up to 10. As coirpith is discarded as waste from coir processing industries, the resulting carbon is expected to be an economical product for the removal of toxic heavy metals from industrial wastewaters.

Synthetic organic dye such as methylene blue (MB) is non-biodegradable and highly toxic, released from textile wastewater. This work investigates the applicability of Ni@ZnO polymer nanocomposite for MB removal from the wastewater. To understand their differences before and after MB adsorption, composites' surface morphology was characterized by various techniques including scanning electron microscope (SEM), thermogravimetric analysis (TGA), X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), Fourier transformation infrared (FT-IR) and UV-Vis spectrophotometer.

Ternary heterojunction BiS/MoS/BiMoO was designed as a signal probe to develop a dual signal amplification strategy empowered electrochemical biosensor for sensitive miRNA-21 detection by combining with catalytic hairpin assembly (CHA). The combination of the BiS/MoS/BiMoO heterojunction as a tracer indication probe and the CHA amplification strategy not only took fully use of the highly dense nanowire interwoven structure and superior active region of the probe, but also endowed the ability to improve the molecular hybridization efficiency by collision, which significantly avoided the cumbersome chain design and greatly simplified the step-by-step construction of the electrode surface. Hairpin H1 was first added dropwise to the gold nanoparticle-decorated electrode surface, and then opened by the introduced miRNA-21 to initiate the specific hybridization.

Whether soil heavy metal pollution contributes to the decline in pollinator populations remains inconclusive. Based on the detection of heavy metals in the nectar, pollen, and bodies of pollinating insects in areas affected by heavy metal pollution, this study aimed to investigate the impact of adding four heavy metals-zinc (Zn), lead (Pb), copper (Cu), and nickel (Ni)-at realistic concentrations to the diet on the pre-oviposition period, larval development period, production of adult bees, and weight of worker bees. The study sought to evaluate the influence of heavy metal accumulation mediated by floral rewards on key stages of growth and development of bumblebee (Bombus terrestris L.
