“…The chemistry and ecotoxicology of harmful heavy metals and metalloids in the environment have revealed that actions should be done to reduce their influence on human health and the ecosystem. The paper [ 15 ] has presented an overview of the heavy metal ions detecting capacity of various quantum dots and their usefulness as a nanosensor for on-field heavy metal ions detection in water. Quantum dots (QDs) are zero-dimensional nanomaterial particles with unique optical and electrical properties that are employed as nanosensors.…”

There are numerous uncertainties associated with environmental health risk assessment (EHRA), and it is unavoidable to apply the best models and information available to save human lives. The EHRA is a method for determining the type and likelihood of adverse health effects on people who are exposed to chemicals in the workplace. To address the environmental health problems caused by harmful gas leakage and water pollution generated by the coastal regional chemical industry, a novel EHRA model for the coastal chemical industry has been developed. The premise of the Gauss plume diffusion model is used to define the model’s parameters and the evaluation criterion for harmful gas concentration health risk. The EHRA model is evaluated against the leakage of harmful gases and consists of three steps. The first step is to identify the threat posed by the chemical industry in the coastal region; the second step is to quantify the risk; the third step is to develop a model for assessing water-related environmental health risk. The water-related environmental health assessor analyzes the pollutant variables and parameters of the assessment model to estimate the health risk caused by dangerous compounds in the water, using the assessment model of chemical carcinogen health risk and noncarcinogen health risk Type B. The experiments’ findings suggest that the model can effectively assess the dangers to human health from hazardous gases and heavy metals in the water bodies of chemical factories in coastal communities.

“…QDs have enriched fluorescence properties which includes broad excitation spectrum, narrow emission spectrum and photostability. At the same time, there are discrete capping agents and different functional groups on its surface, thus increasing the sensitivity of the method ( Biranje et al, 2021 ). Xie et al ( Xie et al, 2021 ) established both ic-ELISA and Fluorescence-Linked Immunosorbent Assay (FLISA) based on QDs to detect AMOZ.…”

Nitrofuran antibiotics have been widely used in the prevention and treatment of animal diseases due to the bactericidal effect. However, the residual and accumulation of their metabolites in vivo can pose serious health hazards to both humans and animals. Although their usage in feeding and process of food-derived animals have been banned in many countries, their metabolic residues are still frequently detected in materials and products of animal-derived food. Many sensitive and effective detection methods have been developed to deal with the problem. In this work, we summarized various immunological methods for the detection of four nitrofuran metabolites based on different types of detection principles and signal molecules. Furthermore, the development trend of detection technology in animal-derived food is prospected.

“… 15 , 37 − 41 The emission wavelength of QDs can be modified via the changing in QDs’ particle size or by selecting a suitable light source for excitation. 42 − 46 QDs exhibit a narrow, tunable, and symmetric emission spectrum compared to organic fluorophores. 47 , 48 However, QDs with small capping agents tend to aggregate or agglomerate.…”

Chitosan-CdS Quantum Dots Biohybrid for Highly Selective Interaction with Copper(II) Ions

Cadmium sulfide (CdS) quantum dots (QDs) were homogeneously embedded into chitosan (CTS), denoted as CdS@CTS, via an in situ hydrothermal method. The intact structure of the synthesized materials was preserved using freeze-drying. The materials were characterized using X-ray diffraction (XRD), X-ray photoelectron spectroscopy, transmission electron microscopy, high-resolution TEM, scanning TEM, dispersive energy X-ray (EDX) for elemental analysis and mapping, Fourier transform infrared spectroscopy, nitrogen adsorption–desorption isotherms, thermogravimetric analysis, UV–vis spectroscopy, and diffuse reflectance spectroscopy (DRS). The synthesis procedure offered CdS QDs of 1–7 nm (average particle size of 3.2 nm). The functional groups of CTS modulate the in situ growth of CdS QDs and prevent the agglomeration of CdS QDs, offering homogenous distribution inside CTS. CdS@CTS QDs can also be used for naked-eye detection of heavy metals with high selectivity toward copper (Cu 2+ ) ions. The mechanism of interactions between Cu 2+ ions and CdS@CTS QDs were further studied.
