Abstract
Three decades ago, several articles on the subjectivity in chemical risk judgments (i.e., labeled "intuitive toxicology") measured the divide between the public and toxicologists with different backgrounds regarding the validity of predicting health effects based on in vivo studies. Similar divides with impacts on societal discourse and chemical risk assessment practices might exist concerning alternative toxicity testing methods (i.e., in vitro and in silico). However, studies to date have focused either on the public's views of in vivo or stem cell testing or on experts' views of in vivo testing and potential alternatives (i.e., toxicologists and medical students), which do not allow for a direct investigation of potential divides. To fill this knowledge gap, we conducted two online surveys, involving members of the German-speaking public in Switzerland and European human health risk assessors, respectively. This article presents the results of these two surveys regarding the divide in the public's and risk assessors' perspectives on risk assessment based on in vivo, in vitro, and in silico testing. Particularly, the survey with the risk assessors highlights that, beyond scientific and regulatory barriers, alternatives to in vivo testing may encounter individual hurdles, such as higher uncertainty associated with them. Understanding and addressing these hurdles will be crucial to facilitate the integration of new approach methodologies into chemical risk assessment practices as well as a successful transition toward next-generation risk assessment, bringing us closer to a fit-for-purpose and more efficient regulatory landscape.

RISK ANALYSIS : AN OFFICIAL PUBLICATION OF THE SOCIETY FOR RISK ANALYSIS 2024; 44:493-507.

Abstract
In the coronavirus disease 2019 era, biocidal products are increasingly used for controlling harmful organisms, including microorganisms. However, assuring safety against adverse health effects is a critical issue from a public health standpoint. This study aimed to provide an overview of key aspects of risk assessment, management, and communication that ensure the safety of biocidal active ingredients and products. The inherent characteristics of biocidal products make them effective against pests and pathogens; however, they also possess potential toxicities. Therefore, public awareness regarding both the beneficial and potential adverse effects of biocidal products needs to be increased. Biocidal active ingredients and products are regulated under specific laws: the Federal Insecticide, Fungicide, and Rodenticide Act for the United States; the European Union (EU) Biocidal Products Regulation for the EU; and the Consumer Chemical Products and Biocide Safety Management Act for the Republic of Korea. Risk management also needs to consider the evidence of enhanced sensitivity to toxicities in individuals with chronic diseases, given the increased prevalence of these conditions in the population. This is particularly important for post-marketing safety assessments of biocidal products. Risk communication conveys information, including potential risks and risk-reduction measures, aimed at managing or controlling health or environmental risks. Taken together, the collaborative effort of stakeholders in risk assessment, management, and communication strategies is critical to ensuring the safety of biocidal products sold in the market as these strategies are constantly evolving.

Abstract
Taking the public discourse on health risks due to aluminum in antiperspirants as an example, we conducted a randomized controlled study with repeated measurements to research how selective reporting of risk information affects risk perception and trust in risk information. First, the study varied the information scope that the experimental subjects received (selective vs. complete information). Selective information highlighted that a health risk is given. Considering the full range of studies, complete information is indicated the opposite. A second variation referred to the facticity of the hazardous agent mentioned in the risk information (a reference to either an actual or fictitious agent). Moreover, the selectively informed subjects received the complete information after the effects of the selective information were measured. Four risk perceptions constructs were chosen as dependent variables, differing on two dimensions (affective vs. cognitive and personal risk vs. risk for others). In addition, subjects´ trust in the given risk information was measured. The study reveals that presenting selective information amplifies risk perceptions. The effect was observed, irrespective of whether the hazardous agent mentioned in the risk information was actual or fictitious. When subjects who first received the selective information obtained the complete information, indicating no elevated risk, risk perceptions decreased. However, the analysis also indicates that corrective information (indicating no risk) is less trusted than selective information that points to health risks. Furthermore, proper toxicological understanding, i.e., taking into account the dose-response relationship, supports the effect of corrective information on risk perceptions.

Abstract
Human security, defined as "freedom from want and fear and freedom to live in dignity", provides an overarching concept to address threats to human security dimensions such as health, food, economics, the environment and sustainable development, while placing the individual at the centre of attention. Chemistry is central to addressing these challenges, but surprisingly its role and contributions to human security have hitherto not been explicitly set out. This article situates chemistry in the human security framework, highlighting areas where chemistry knowledge, methods and products are vital. It underscores three complementary facets: 1) chemistry contributes to many dimensions of human security, but needs to do much more in the light of oncoming global challenges; 2) the human security framing illuminates areas where chemistry itself needs to adapt to contribute better, by intensification of current approaches and/or by building or strengthening chemistry tools, skills and competencies; and 3) repositioning as central to human security affords chemistry a powerful opportunity to refresh itself as a science for the benefit of society-and it will need to engage more directly and dynamically at the interface of science, society and policy in order to do so.

Trace chemicals in consumer products - Consumers' acceptance before and after receiving information about toxicological principles. Food Chem Toxicol 2021; 153:112252. [PMID: 33961928 DOI: 10.1016/j.fct.2021.112252] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Revised: 04/28/2021] [Accepted: 04/30/2021] [Indexed: 11/21/2022]
Abstract
Toxicologists face several challenges when communicating with the public about the potential risks of chemical substances in consumer products. However, based on the consumers' scepticism and detachment from the use of chemical substances in the manufacturing of consumer goods, evidence is needed on how this communication can be improved. Hence, the goal of this study was to experimentally check the effect of an informational video on consumers' acceptance of trace chemicals in consumer products, their willingness to purchase and finally, their perception of the dose-response mechanism. For this, an informational video was developed and evaluated in a pre-post online study with a sample of South Korean consumers (N = 600). The results suggest that providing information on toxicological principles increases people's acceptance of trace chemicals in consumer products and their willingness to purchase a consumer product containing trace chemicals. Within the article, implications for practice and ideas for new research avenues are presented.
