“…Ionic gel formation depends mainly on the alginate affinity to the cross-linking ions, which decreases in series: Pb > Cu > Cd> Ba > Sr > Ca > Co, Ni/Zn > Mn [ 20 , 21 ]. Whereas the use of Ba 2+ , Sr 2+ , and Pb 2+ is limited due to their potentially toxic effect on the human organism [ 22 , 23 , 24 ], the calcium(II) ion is the most used due to it having the safest profile and a solid cross-linking ability, being a golden standard for external ionic gelation [ 25 ]. Only few papers dealing with cross-linking via ion mixture have been published [ 26 ], even though it could provide some advantages including the reduction in single cation weaknesses regarding both technological and biological aspects.…”

Antimicrobial agent abuse poses a serious threat for future pharmacotherapy, including vaginal administration. The solution can be found in simple polymeric systems with inherent antimicrobial properties without the need to incorporate drugs, for instance alginate beads cross-linked by bivalent ions. The main goal of the presented study was to provide improvement on the well-documented cytotoxicity of Cu2+ cross-linked alginate. Alginate beads were prepared by external ionotropic gelation by cross-linking with Cu2+, Ca2+ and Zn2+ ions, separately and in mixtures. Morphological properties, swelling capacity, ion release and efficacy against the most common vaginal pathogens (C. albicans, E. coli, E. faecalis and virus strain—human herpesvirus type 1) were evaluated. The prepared particles (particle size 1455.68 ± 18.71–1756.31 ± 16.58 µm) had very good sphericity (0.86 ± 0.04–0.97 ± 0.06). In mixture samples, Cu2+ hampered second ion loading, and was also released incompletely (18.75–44.8%) compared to the single ion Cu2+ sample (71.4%). Efficacy against the selected pathogens was confirmed in almost all samples. Although anticipating otherwise, ion mixture samples did not show betterment over a Cu2+ cross-linked sample in cytotoxicity–pathogen efficacy relation. However, the desired improvement was found in a single ion Zn2+ sample whose minimal inhibition concentrations against the pathogens (0.6–6.12 mM) were close to, or in the same mathematical order as, its toxic concentration of 50 (1.891 mM). In summary, these findings combined with alginate’s biocompatibility and biodegradability give the combination solid potential in antimicrobial use.

“…Barium enters the air during refining processes and coal and oil combustion, and its compounds that dissolve in water can be harmful to human health. Extraordinarily large amounts of barium that are water-soluble may cause paralysis and even death [45]. Nevertheless, the common amount of barium found in food and water is typically low and not harmful to human health.…”

“…Nevertheless, the common amount of barium found in food and water is typically low and not harmful to human health. Workers in the barium-related industry have a higher risk of barium exposure [45]. While iodin, 2,3,7,8 tetracholodibenzo-p-dioxin (TCDD) is produced from burning or heating of commercial, and it might affect the reproductive system when excessively exposed [46].…”

In the development of packaging products, the considerations are not limited to the food shelf-life, safety, and practicality, but also environmental sustainability. This paper reports a life cycle assessment (LCA) analysis of a proposed natural fiber-reinforced biopolymer composite takeout food container. The study focuses on the damage assessment of the whole product system, including disposal scenarios of the thermoformed sugar palm fiber (SPF)-reinforced sago starch composite takeout food container. The analysis performed was to anticipate the environmental impact of the cradle-to-grave approach. The results exhibited the total human health damage of 2.63 × 10−5 DALY and ecosystem damage of 9.46 × 10−8 species.year per kg of containers. The main contributor was the carbon dioxide emission from fossil fuel combustion for energy generation that contributed to climate change and caused human health and the ecosystem damages with low-level metrics of 1.3 × 10−5 DALY and 7.39 × 10−8 species.yr per kg of containers, respectively. The most contributed substances in the ‘Particulate matter formation’ impact categories that caused respiratory diseases were from air/nitrogen oxides, air/particulates, <2.5 µm, and air/sulphur dioxide with the metrics of 2.93 × 10−6 DALY, 2.75 × 10−6 DALY, and 1.9 × 10−6 DALY per kg containers, correspondingly. Whereas, for the ‘Agricultural land occupation’, which contributed to ecosystem damage, almost the total contributions came from raw/occupation, forest, intensive with the metric of 1.93 × 10−9 species.yr per kg of containers. Nevertheless, from the results, all impact categories impacted below than 0.0001 DALY for the Human Health damage category and below 0.00001 species.yr for the ecosystem damage category. These results would provide important insights to companies and manufacturers in commercializing the fully biobased takeout food containers.
