Scale Model Experiment on Local Scour around Submarine Pipelines under Bidirectional Tidal Currents

Journal of Marine Science and Engineering, 2021
In nearshore regions, bidirectional tidal flow is the main hydrodynamic factor, which induces local scour around submarine pipelines. So far, most studies on scour around submarine pipelines only consider the action of unidirectional, steady currents and

Microplastics and nanoplastics in water: Improving removal in wastewater treatment plants with alternative coagulants

The Canadian Journal of Chemical Engineering, EarlyView.
The contaminant removal performance of a conventional coagulant, alum, and alternative coagulants, aluminium chlorohydrate (ACH) and ACH + pDADMC, are compared in challenging wastewater treatment conditions (pH >7.8). The interactions of each coagulant with a negatively charged surface are depicted based on quartz crystal microbalance with dissipation ...

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

Ecography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

Toxic Metals in Dried Marine Fish and Implications for Human Health in Bangladesh and Exporting Countries

Food Safety and Health, EarlyView.
This study assessed toxic metals in five dried marine fish species from Bangladesh. Although most metals were within safe limits, chromium (Cr) consistently exceeded FAO/WHO standards, especially at Kuakata Beach. The findings highlight localized contamination hotspots and species‐specific bioaccumulation, while risk assessment supports the safety and ...
