ClearComprehensive Insight from Phthalates Occurrence: From Health Outcomes to Emerging Analytical Approaches
This review summarizes the widespread occurrence of phthalates, chemicals commonly used as plasticizers in plastic products, and their potential health effects including endocrine disruption and reproductive harm. The study also surveys emerging analytical methods for detecting phthalates in food, water, and biological samples, highlighting the challenge of daily human exposure through consumer products.
Unpacking Phthalates from Obscurity in the Environment
This review traces how advances in analytical chemistry have brought phthalates, a group of plastic additives, from relative obscurity to recognition as widespread environmental contaminants. Phthalates leach easily from plastic products because they are not chemically bound to the polymer, and they are now categorized as endocrine-disrupting chemicals with potential links to organ damage. The study discusses the evolving methods for detecting phthalates in complex environmental and biological samples.
