DRAFT-PATCH: a multi-pass large-language-model protocol for extracting monitoring data from the primary literature
AI summary Read the abstract
Scientists have created an AI tool that can automatically read thousands of research papers and pull out data on contaminants like "forever chemicals" (PFAS), pesticides, and microplastics found in water, soil, and food. This matters because it helps researchers spot gaps in contamination monitoring and understand how these chemicals move between different environments, information that's currently scattered across too many studies for humans to easily compile by hand. Faster, more reliable tracking of contaminants could ultimately help identify pollution risks before they become bigger health concerns.
DRAFT-PATCH reads primary publications and writes structured monitoring records. A first pass drafts the records; up to four further passes re-read the source and correct omissions and formatting errors, which is what makes extraction reliable enough to run across thousands of papers. The protocol is schema-driven and not specific to PFAS: the same pipeline can be pointed at pharmaceuticals, pesticides, microplastics or any contaminant whose measurements are scattered through the literature. This repository holds the tool and every analysis built on its output for theaccompanying paper: - 01_extraction_draft_patch - the extraction tool itself: prompts, the multi-pass correction loop, a browser interface, Docker setup and a packaged benchmark.- 02_benchmark_scoring - scoring against hand-curated ground truth. Extracted rows are aligned one-to-one to ground truth by Hungarian matching on a weighted field score (PFAS type 0.10, location 0.20, date 0.20, concentration 0.30, unit 0.20); a row counts as a true positive at 0.70. Includes the alignment-threshold sensitivity analysis.- 03_meta_analysis - harmonisation and random-effects meta-analysis of co-measured pairs, yielding cross-media transfer factors. Entry point run_site_level_meta.py.- 04_occurrence_and_gaps - catchment construction, compositional analysis (CLR-PCA and non-negative matrix factorisation), source association, and the monitoring-coverage audit.- 05_figures - plotting scripts for the main and supplementary figures.

DRAFT-PATCH: a multi-pass large-language-model protocol for extracting monitoring data from the primary literature
AI summary Read the abstract
Scientists have created an AI tool that automatically reads through thousands of research papers and pulls out data on contaminants like "forever chemicals" (PFAS), pesticides, and microplastics, a task that would take humans years to do by hand. This matters because it can quickly reveal gaps in our monitoring of harmful chemicals in the environment, helping researchers and regulators spot where dangerous contaminants might be slipping through the cracks undetected.
DRAFT-PATCH: a multi-pass large-language-model protocol for extracting monitoring data from the primary literature
AI summary Read the abstract
Researchers built an AI tool called DRAFT-PATCH that automatically reads scientific papers and pulls out data on contaminants like "forever chemicals" (PFAS), pesticides, and microplastics, work that normally takes humans months or years to do by hand. By checking its own work multiple times, the tool becomes accurate enough to scan thousands of studies at once, which could help scientists and regulators spot pollution patterns and gaps in monitoring much faster than before. This matters because better, faster tracking of harmful chemicals in our environment is a key step toward understanding and reducing our exposure to them.
Artificial intelligence enabled detection of emerging contaminants in waste and wastewater systems
AI summary Read the abstract
Our wastewater often contains tiny amounts of hard-to-detect pollutants—like drug residues, hormone-disrupting chemicals, PFAS ("forever chemicals"), microplastics, and antibiotic-resistant bacteria—that regular lab tests can easily miss. This review paper (which summarizes existing research rather than presenting new experiments) explains how artificial intelligence can scan complex wastewater data to catch these contaminants faster and more accurately than older methods, which could help catch pollution problems before they spread into our water and food systems. That said, the technology isn't ready for widespread real-world use y
Integrating Computational Tools and Machine Learning for Microbial Enzyme Engineering in Persistent Pollutant Management: A Systematic Review from Detection to Recycling
AI summary Read the abstract
Scientists are using AI tools (like AlphaFold, the program that predicts protein shapes) to design custom microbial enzymes that can break down stubborn pollutants like PFAS ("forever chemicals"), microplastics, and other toxic industrial chemicals that build up in our environment and bodies. This paper reviews existing research on these computational methods rather than presenting new lab results, but it matters because faster, smarter enzyme design could eventually lead to real-world tools for cleaning up the pollutants linked to health problems like hormone disruption and cancer risk.
Modelling the fate of chemicals of emerging concern in wastewater treatment: From mechanistic models to hybrid data driven approaches
AI summary Read the abstract
Everyday chemicals from medicines, cleaning products, and plastics often slip through wastewater treatment plants and end up back in our environment, potentially in our water supply. This review looked at different computer modeling approaches—including newer AI-based methods—that scientists use to predict how well treatment plants remove these pollutants, finding that combining traditional science-based models with machine learning works best. The authors note we still need better tools to track particularly concerning substances like PFAS ("forever chemicals") and microplastics, which matters because understanding how well treatment plants filter these out helps protect the water we drink and use every day.
