“…Results of the study found that over 50 toys contained Pb concentrations exceeding those allowed by Brazilian law, which stipulates a limit of 600 ppm for lead (Silva et al 2018;Brazil 2008). Similarly, the presence of these and other toxic metals in plastic toys has been reported in many countries, including Kazakhstan (Akimzhanova et al 2020), China (Kang and Zhu 2015;Cui et al 2015) and the UK (Turner 2018).…”

Lead is a highly neurotoxic chemical element known for reducing intelligence quotient (IQ) and promoting antisocial behavior in children and adolescents, while cadmium is a carcinogenic bioaccumulative element. Contaminated foods and beverages are the most common routes of exposure. The objective of this study was to determine Cd and Pb concentrations in colored plastic utensils for use by children and to measure the speci c migration of these elements into beverages and foods. Pb and Cd concentrations were determined using a handheld XRF. Speci c migration tests were conducted using the simulant solutions. Migration levels were determined by ICP-MS and migration tests for Pb were also performed on actual samples GF-AAS determination. Utensils (n=87) were purchased for containing Cd and/or Pb concentrations above permitted limits. The mean of Pb and Cd were 1110 and 338 ppm respectively. For speci c migration assays, Pb levels were 187, 13 and 380 times above the permitted limit for acetic acid, water and orange juice, respectively. Cd levels 50 and 2.4 times above the permitted limit for acetic acid and water, respectively. The districts where the utensils were purchased were grouped according to their Social Vulnerability Index and compared using ANOVA. Results revealed a group difference in mean Pb levels for low versus medium/high social vulnerability (p = 0.006). The ndings corroborate the initial hypothesis that these utensils constitute a major source of exposure to PTEs such as Cd and Pb.

“…This attitude also raises an alert of possible problems to human health caused/aggravated by the use of plastics with the presence of the keywords “endocrine disruption,” “carcinogenesis,” “allergen,” and “biogenic toys” [ 74 ] (to avoid “children contamination” [ 95 ]). These keywords express some consumer concerns about the use of plastics.…”

Plastic makes our society more practical and safer. It is hard to consider eliminating plastic in some sectors, such as the medical field. However, after use, plastic waste becomes a global problem without precedents, and when not properly disposed of, it can cause several socio-environmental problems. Some possible solutions are recycling, the circular economy, proper waste management, and consumer awareness. Consumers play a crucial role in preventing problems caused by plastic. In this work, consumer awareness of plastic is discussed according to the point of view of the research areas—environmental science, engineering, and materials science—based on the analysis of the main authors’ keywords obtained in a literature search in the Scopus database. Bibliometrix analyzed the Scopus search results. The results showed that each area presents different concerns and priorities. The current scenario, including the main hotspots, trends, emerging topics, and deficiencies, was obtained. On the contrary, the concerns from the literature and those of the daily lives of consumers do not seem to fit in, which creates a gap. By reducing this gap, the distance between consumers awareness and their behavior will be smaller.
