Special Issue Information

Dear Colleagues,

Microcystins (MCs) are highly toxic substances widely distributed in lakes, and pose a hazard to human health. A large number of detection methods have been developed to avoid the harm of MCs. However, current detection methods can only detect MCs in water samples, have low sensitivity and require complex operation procedures. Therefore, we believe that it is necessary to develop a novel tool for the detection of MCs in lake waters and biological systems. Thus, in this Special Issue, we solicit papers which develop novel environment materials for detecting MCs with sensitivity and selectivity.

We are pleased to invite you to develop novel materials for achieving detection of MCs with high sensitivity. Studies may make use of organic and functional materials, nanomaterials, photoelectric materials, etc. The detection technologies of MCs could include fluorescence technology, immune technology, and electrochemical technology, as examples. Compared to traditional methods (e.g., high-performance liquid chromatography (HPLC), liquid chromatography-mass spectroscopy (LC-MS), protein phosphatase inhibition (PPI), and enzyme-linked immunosorbent assay (ELISA)), novel methods should show higher sensitivity and selectivity.

This Special Issue aims to support the development of novel methods for the detection of MCs with sensitivity in lake waters and biological systems.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: fluorescence detection; environmental materials; pollution remediation; detection and application; biological imaging; immune technology; and electrochemical technology.

We look forward to receiving your contributions.

Triclosan (TCS) has been widely employed as active ingredient in household products and has received attention for its hepatotoxicity, endocrine disruption and disturbance on immune function. Polylactic acid (PLA) has been highlighted as an alternative biodegradable microplastic, and the knowledge about the adsorption affinity towards TCS is limited. In this study, the ability to act as carrier of TCS by PLA and non-biodegradable microplastics, including polystyrene (PS), polyvinyl chloride (PVC) and polyethylene (PE) with different particle sizes were explored. The influence factors (e.g., dosage, pH and salinity), adsorption kinetics and isotherms were also investigated. Batch experiment results indicated that the TCS adsorption onto PLA and non-biodegradable microplastics exhibited a pronounced pH-dependent pattern (pH of 4, 7 and 10), and the adsorption capacity decreased gradually as pH increased. Furthermore, the adsorption capacity of TCS on PS, PVC and PE decreased as salinity increased from 0 to 3.5%, while no significant inhibition for the sorption capacity of PLA was observed. The adsorption kinetic data of TCS was best fitted with the pseudo-second order model. The Freundlich model with R2 (0.999) was suitable to describe the adsorption isotherms of TCS on PLA, while the isotherms data of TCS on PS, PVC and PE was fitted by linear and Freundlich model. The higher adsorption capacity of PLA (38.6 mg g−1) compares to those of PS, PVC and PE (31.3, 11.4 and 9.64 mg g−1, respectively), illustrated by the fact that the physicochemical properties of microplastics have a noticeable impact on adsorption process, and the biodegradable PLA is a stronger vector than the non-biodegradable microplastics.
