Abstract

Introduction: The generation and increase of electronic waste (e-waste) represents a focus of attention in the biomedical area due to the devastating impact on health. The importance and study ranges from toxicological understanding in adults to teratological effects in neonates. Studies have shown that e-waste affects the uptake of micronutrients, in addition to environmental contamination. Objective: To describe the main nutritional effects of e-waste in vulnerable populations. Methods: A retrospective descriptive model was performed following the PRISMA model, including manuscripts that were published since 2015. Results: Of the total number of articles identified, 21 articles were selected that met the established criteria. E-waste has a great impact on the environment by contaminating soil, food, vegetables, and air. Through these routes, children, pregnant women, and recyclers can acquire different toxic compounds. The main affectations described are alterations in iron metabolism and glycemic index, metabolic alterations, changes in the microbiota, affectation in the synthesis of antibodies and metabolic activity of reparative enzymes. Conclusions: Personnel in nutrition and related areas should understand the mechanism of action of e-waste, nutrient utilization, and the effect of metals and compounds derived from e-waste to avoid nutritional deficiencies
