This review explores current knowledge on the environmental, oxidative, and genomic effects of sucralose (E955), an artificial sweetener widely used in food products, including those for children, and known to cross both the placental barrier and into breast milk. Although initially considered safe, research conducted over the past two decades has presented conflicting evidence regarding its long-term impact, particularly on ecosystems and biological systems. Structurally similar to chlorinated compounds such as perfluoralkyl substances (PFAS), sucralose is highly persistent in the environment, which complicates its degradation and removal, especially from aquatic systems. Several studies have reported behavioral, metabolic, and even genomic alterations in aquatic organisms exposed to sucralose, raising concerns about its broader ecological safety. In addition, its presence has been linked to shifts in microbiota composition in both environmental and human contexts. Reports of sucralose-induced oxidative stress further highlight the need for caution in its continued use, particularly in sensitive formulations. Given its widespread presence and resistance to degradation, further investigation into the environmental and biological safety of sucralose is urgently needed.

This review presents an in-depth analysis of the latest methods used for the determination of sucralose (E955), focusing on research conducted over the past 10 years. As a widely used sugar substitute in the food and pharmaceutical industries, sucralose has raised concerns about its environmental persistence, potential genotoxicity, and health impacts. This study examines several spectrophotometric, chromatographic, and electrochemical techniques, evaluating their sensitivity, selectivity, and limitations in differentiating sucralose from natural carbohydrates and other sweeteners. The review highlights the pressing need for novel detection methods that not only improve accuracy in trace detection but also address growing concerns about its bioaccumulation and conversion into harmful metabolites. Advancing these analytical techniques is essential for enhancing food safety, public health surveillance, and environmental risk assessment. Chromatographic methods are dominant in sucralose determination in foods and environmental objects, as they allow the determination of sucralose at micro- and nanomolar levels. However, spectrophotometric and electrochemical methods are frequently used as complementary to chromatographic methodologies, sensitizing them. On the other hand, purely spectrophotometric methods are less popular, and electrochemical methods remain underdeveloped. Therefore, the advancement of sucralose determination must be due to cheaper chromatographic and classical electrochemical methods.

Bisphenol A (BPA) is one of the most produced compounds worldwide. It acts as an endocrine disruptor and can cause adverse effects in the body, even at low-dose exposures. By interacting with estrogen receptors, it can play an important role in the pathogenesis of several endocrine diseases, such as infertility, hormone-dependent tumours and various metabolic disorders. Exposure in humans, especially early in life, is of particular concern, since it can have a big impact on an individual’s development and growth. The objective of this study was to evaluate, in vivo, the genotoxicity of BPA and its effects on longevity, prolificacy and behaviour in Drosophila melanogaster. To evaluate the biological and behavioural effects, flies were crossed and subjected to different concentrations of BPA (0.5 mM, 1 mM, 2 mM, 5 mM and 10 mM) in Drosophila instant “Carolina” medium hydrated with the BPA solution for 3 days, and then transferred to a non-treated medium, where they continued to lay eggs. This procedure was repeated to obtain the F2 generation. To evaluate genotoxicity, the somatic mutation and recombination test (SMART) and Comet assays were performed. In these cases, higher concentrations of BPA were chosen (1 mM, 10 mM, 20 mM and 50 mM). The results showed that this compound caused changes in longevity and prolificacy, and that these changes also affected subsequent generations. They also showed that BPA affected Drosophila’s behaviour and social interaction, but at the exposure levels investigated here, it did not cause significant genotoxic effects.

The use of sweeteners in e-cigarette liquids has become increasingly common, aiming to enhance the sensory appeal of vaping products. Compounds like aspartame, saccharin, and sucralose are added to provide a sweet taste without any calories, especially in flavored e-liquids popular among younger users. However, recent studies suggest that these additives may pose significant health risks when vaporized and inhaled. Sucralose, in particular, can break down into potentially harmful chlorinated by-products at high temperatures typical of vaping devices. Moreover, there is growing concern about the synergistic effects of sweeteners like sucralose, one sweetener with another and when combined with other e-liquid components. It has been observed that the presence of sucralose may amplify oxidative stress; genotoxicity, including mutations; and overall toxicity, along with environmental impact. This is not limited to nicotine- and smoke-related harm, as it may strengthen the toxic effect of the substances used in e-liquids that are not present in traditional cigarettes. The combined exposure to these heated compounds can intensify cytotoxicity, potentially increasing the risk of respiratory, cardiovascular, and neurological effects over time. While marketed as safer alternatives to tobacco, e-cigarettes containing sweeteners like sucralose may introduce new and poorly understood toxicological hazards that deserve urgent regulatory attention.
