bioacc

bioacc analyzes accumulation-depuration toxicokinetic (TK) data to quantify chemical bioaccumulation metrics such as Bioconcentration Factor (BCF), Biota-Sediment Accumulation Factor (BSAF), and Biomagnification Factor (BMF) for environmental risk assessment.

Key Features:

• Toxicokinetic (TK) modeling: Fits TK models to accumulation-depuration time-series to capture internal concentration dynamics during accumulation and depuration phases.
• Bioaccumulation metrics: Computes Bioconcentration Factor (BCF), Biota-Sediment Accumulation Factor (BSAF), and Biomagnification Factor (BMF) from fitted TK models.
• Temporal dynamics analysis: Quantifies absorption, retention, and elimination kinetics of chemicals within organisms over time.
• Bioaccumulation test support: Applies model fitting specifically to data from bioaccumulation tests to derive internal concentration profiles.
• Literature-derived datasets: Includes an extensive collection of raw TK datasets extracted from scientific publications for modeling and analysis.

Scientific Applications:

• Regulatory bioaccumulation assessment: Provides metrics and TK analyses relevant to market authorization and regulatory evaluation of active substances.
• Environmental risk assessment: Supports estimation of chemical bioaccumulation potential and exposure dynamics in ecological risk frameworks.
• Toxicokinetic research: Enables quantitative analysis of uptake, depuration, and internal concentration trajectories for chemicals in organisms.
• Data reuse and comparative studies: Facilitates modeling across literature-extracted TK datasets to compare bioaccumulation behavior between substances and species.

Methodology:

Fitting toxicokinetic (TK) models to accumulation-depuration time-series from bioaccumulation tests to estimate internal concentration dynamics and derive BCF, BSAF, and BMF using literature-extracted raw TK datasets.
