From DNA to Multiorgan Effects: An Analysis of Everyday Chemical Toxicity and Hidden Toxic Threats to Human Health

Abstract

Exposure to hazardous chemicals has become increasingly embedded in everyday life through food, medicines, air pollution, cosmetics, and other consumer products. However, toxicity is still frequently examined separately according to the type of toxicant or target organ, leaving the relationships among genetic damage, exposure pathways, and multiorgan effects insufficiently integrated. This study aims to analyze patterns of everyday chemical toxicity from the genetic level to their manifestations in various organs. A qualitative document analysis was conducted using one core manuscript covering chemical carcinogenesis, genetic toxicology, hepatotoxicity, respiratory toxicity, neurotoxicity, and skin toxicity, supplemented by relevant scientific literature. The analysis involved in-depth reading, coding, categorization, thematic synthesis, and narrative interpretation. Three main findings were identified. First, chemical exposure may induce genetic damage that serves as an early pathway in the development of chronic disorders. Second, the liver and respiratory system emerged as the dominant target organs in the analyzed document because of their roles in xenobiotic metabolism and pollutant entry. Third, the nervous system and skin exhibited risks of toxic accumulation that may not be immediately recognized, particularly following repeated low-dose exposure. These findings indicate that everyday chemical toxicity should be understood across biological levels and organ systems. However, the results should be interpreted as a conceptual synthesis rather than as quantitative evidence derived from primary measurements. Future research should employ biomarkers, biomonitoring, and multiroute exposure analysis to examine these relationships more empirically and assess their causal implications.
