Tetramethyl Bisphenol F: Organ- and System-Specific Toxicity, Current Status, and Perspectives.

Area of Science:

• Toxicology
• Endocrinology
• Environmental Health

Background:

• Tetramethyl bisphenol F (TMBPF) is widely adopted as a Bisphenol A (BPA) alternative, particularly in food can coatings.
• Initially perceived as safer due to a lack of estrogenic effects, TMBPF is marketed as 'BPA-free'.
• Early studies suggested lower toxicity compared to BPA, driving its market expansion.

Purpose of the Study:

• To review current toxicological findings on TMBPF.
• To discuss the implications for future research and regulatory actions.
• To highlight the importance of proactive public health assessments.

Main Methods:

• Comprehensive literature review of recent toxicological studies on TMBPF.
• Analysis of reported adverse effects across multiple biological systems.
• Evaluation of endocrine-disrupting potential and neurodevelopmental toxicity.

Main Results:

• Growing evidence indicates TMBPF causes cytotoxicity, apoptosis, and endocrine disruption (thyroid, skeletal, neurodevelopmental, reproductive).
• Variability exists in estrogen/androgen effects and obesogenic potential, but significant impacts are noted.
• Neurodevelopmental toxicity is a key concern, potentially irreversible and manifesting after long-term exposure.

Conclusions:

• TMBPF exhibits a concerning toxicological profile, challenging its 'safe substitute' status.
• Environmental accumulation and biomagnification pose long-term risks despite minimal current leaching.
• Urgent, comprehensive toxicological evaluation is needed to inform regulation and ensure consumer safety.
