Behavioural And Cyto-Genotoxic Effects In Adult Rats And Induced Congenital Anomalies To Their Embryos, Exposed To Environmentally Relevant Concentrations Of Phthalates

Objective:

This study investigated the long-term effects of environmentally relevant, low-dose exposure to two common phthalates—di(2-ethylhexyl) phthalate (DEHP) and dibutyl phthalate (DBP)—on adult female Wistar rats and their offspring. The research focused on behavioral changes, physiological parameters, cyto-genotoxicity in bone marrow, and embryotoxicity, using concentrations reflective of contamination levels found in Lithuanian wastewater.

Key Findings:

1. Behavioral Effects:

• No consistent, significant changes were observed in anxiety-like or locomotor behaviors across standardized tests (Open Field, Elevated Plus Maze, Running Wheel).
• Behavioral assessments were exploratory and not statistically powered; results should be interpreted with caution.

2. Physiological Parameters:

• No significant changes in body weight were detected after two months of exposure.
• Minor alterations in blood parameters (e.g., white blood cell count, mean corpuscular hemoglobin concentration) were observed but remained within normal ranges, suggesting limited systemic toxicity at these doses.

3. Cyto-Genotoxic Effects:

• Significant genotoxicity: All exposed groups showed a marked increase in micronuclei formation in polychromatic erythrocytes (PCEs), indicating chromosomal damage.
• Cytotoxicity: The PCE/NCE ratio decreased significantly, indicating disrupted erythrocyte proliferation and accelerated cell aging.
• Effects were observed even at the lowest environmentally relevant doses (200 μg/kg DEHP, 100 μg/kg DBP) and were more pronounced at higher doses.

4. Embryotoxic Effects:

• Non-monotonic dose response: Lower doses (environmentally relevant) resulted in lighter and shorter embryos, while higher doses led to heavier and longer embryos compared to controls.
• Increased embryopathology: All exposed groups showed embryo resorptions and gross morphological abnormalities (e.g., hematomas, hemorrhages, placentomegaly).
• The highest pathology rates were in high-dose groups (up to 32.76%), but even low-dose DBP (100 μg/kg) caused 12.50% pathologies.

Conclusions:

• Long-term exposure to environmentally relevant concentrations of DEHP and DBP does not produce overt behavioral or physiological changes in adult female rats.
• However, these doses induce significant cyto-genotoxic damage in bone marrow and cause embryotoxic effects, including growth alterations and congenital abnormalities.
• The observed non-monotonic dose response highlights the complex toxicity profile of phthalates and underscores the inadequacy of high-dose studies for predicting low-dose risks.
• The findings raise serious concerns about the potential hidden health risks of chronic low-level phthalate exposure, particularly for reproductive and developmental outcomes.
