“…Under these circumstances, carbon dots (CDs) outstand from the numerous fluorescence materials for their good aqueous solubility, − high biological safety, , and nanoscale size. − Most of the CDs could be successfully modified at the molecular level to produce nanoscale luminescent materials for the detection of various targets, − including reactive oxygen species, − metal ions, , antibiotics, , and enzymes. , However, bifunctional sensors, which could detect aqueous metal ions and anions simultaneously, were rare to see. Hence, the design and development of novel bidirectional sensors would be very interesting and significant.…”

Devising novel water-soluble carbon dots (CDs) with a facile and economical process is pivotal for the detection of ions in the environment. In this paper, novel nanoscale CDs (polyethyleneimine-2,4-dihydroxybenzoic acid (PEI-DA)) with water solubility and bifunctional detection were synthesized from hyperbranched polyethyleneimine (hPEI) and 2,4-dihydroxybenzoic acid (DA) via a hydrothermal reaction and further self-assembly. PEI-DA exhibited a good linear relationship with Cu2+ or ClO– in the range of 0–30 μM, and its detection limit was determined to be 193 nM (Cu2+) or 478 nM (ClO–). Meanwhile, PEI-DA presented excellent hypotoxicity and biocompatibility in living cells (HeLa cells). On the basis of extraordinary fluorescence properties, PEI-DA-doped solid sensors (test strips and nanofibrous films) were successfully employed to monitor targets sensitively. More importantly, the fluorescence hydrogel was further constructed to rapidly respond to targets (Cu2+ and ClO–), and it could effectively remove Cu2+ in aqueous solution through adsorption ability. In summary, these simple sensing techniques could be implemented as effective tools to monitor Cu2+ and ClO– in environmental and biological samples.

“…Copper oxide and zinc oxide nanoparticles are both important anthropogenic pollutants (Neff & Dharmarajan 2021 ). Both free-living and parasitic stages of Marshallagia marshalli , a trichostrongylid nematode of sheep, are sensitive to copper oxide and zinc oxide nanoparticles in vitro, as evidenced by concentration-dependent decreases in egg hatching, larval motility, and adult motility and survival (Jalali et al 2021).…”

“…This raises the possibility that nanoparticles in the environment may negatively affect free-living eggs and nematode larvae. Copper has also been suggested to influence transmission of Dirofilaria by altering vector competence (Neff & Dharmarajan 2021). Exposure of larval mosquitoes to 600 ug/L copper, a concentration considerably below the U.S. Environmental Protection Agency safe drinking limit of 1300 ug/L, not only lowered survival of the mosquito larvae but also lowered survival and fecundity of Dirofilaria- infected adult females.…”

Helminth-host-environment interactions: Looking down from the tip of the iceberg

In 1978, the theory behind helminth parasites having the potential to regulate the abundance of their host populations was formalized based on the understanding that those helminth macroparasites that reduce survival or fecundity of the infected host population would be among the forces limiting unregulated host population growth. Now, 45 years later, a phenomenal breadth of factors that directly or indirectly affect the host–helminth interaction has emerged. Based largely on publications from the past 5 years, this review explores the host–helminth interaction from three lenses: the perspective of the helminth, the host, and the environment. What biotic and abiotic as well as social and intrinsic host factors affect helminths? What are the negative, and positive, implications for host populations and communities? What are the larger-scale implications of the host–helminth dynamic on the environment, and what evidence do we have that human-induced environmental change will modify this dynamic? The overwhelming message is that context is everything. Our understanding of second-, third-, and fourth-level interactions is extremely limited, and we are far from drawing generalizations about the myriad of microbe-helminth-host interactions.Yet the intricate, co-evolved balance and complexity of these interactions may provide a level of resilience in the face of global environmental change. Hopefully, this albeit limited compilation of recent research will spark new interdisciplinary studies, and application of the One Health approach to all helminth systems will generate new and testable conceptual frameworks that encompass our understanding of the host–helminth–environment triad.

“…Heavy metals. Heavy metal pollution in the freshwater ecosystem poses a great threat to the growth of aquatic insects [ 119 , 120 ]; therefore, there is a growing concern that it will eventually affect the health of humans [ 121 , 122 ]. Up to date, over 33 metallic elements of aquatic edible insects have been detected, and heavy metals, such as Hg, Pb, Cd, and Cr, have attracted serious concern [ 123 ].…”

“…Meanwhile, the mercury content in carnivorous insects was generally higher than that in herbivorous insects, and the mercury content in aquatic insects was much higher than that in terrestrial insects ( t -test, p < 0.01), with the investigation of 42 insect species from Yunnan, China [ 58 ]. Many studies [ 121 , 127 , 128 , 129 , 130 , 131 , 132 ] have indicated that the larvae of aquatic insects accumulate metals in aquatic ecological environments and retain them until the adult stage. After being preyed on by bats, spiders, birds, fish, and so on, they become the connector of the aquatic and terrestrial food chains, and, thus, bring metal elements into the terrestrial food chain.…”

Edible insects have great potential to be human food; among them, aquatic insects have unique characteristics and deserve special attention. Before consuming these insects, the nutrition and food safety should always be considered. In this review, we summarized the species diversity, nutrition composition, and food safety of edible aquatic insects, and also compared their distinguished characteristics with those of terrestrial insects. Generally, in contrast with the role of plant feeders that most terrestrial edible insect species play, most aquatic edible insects are carnivorous animals. Besides the differences in physiology and metabolism, there are differences in fat, fatty acid, limiting/flavor amino acid, and mineral element contents between terrestrial and aquatic insects. Furthermore, heavy metal, pesticide residue, and uric acid composition, concerning food safety, are also discussed. Combined with the nutritional characteristics of aquatic insects, it is not recommended to eat the wild resources on a large scale. For the aquatic insects with large consumption, it is better to realize the standardized cultivation before they can be safely eaten.
