Balancing nutrition gains and microplastic exposure reduction in global bivalve consumption
Summary
Eating shellfish like clams, mussels, and oysters comes with a tradeoff: you get valuable nutrients, but you also swallow tiny plastic particles that come from ocean pollution. This research provides the data and tools to measure that tradeoff country by country and tests strategies, like cleaning up pollution, changing trade patterns, or shifting what types of shellfish people eat, to help people keep the nutritional benefits while cutting down on microplastic exposure. In short, it's a toolkit for figuring out how we can eat seafood more safely without giving up its health perks.
This record provides the input data and executable Python scripts required to reproduce the main computational results of the study on global bivalve-associated microplastic exposure, nutritional benefits and exposure intensity. The package corresponds to the analysis and contains three self-contained modules: 1. Result 1 reproduces 2023 country-level and global/income-group results for microplastic exposure, nutritional benefits and exposure intensity. 2. Result 2 reproduces the factor decomposition of exposure intensity from 2013 to 2023 at the country level and for global and income-group aggregates. 3. Result 3 reproduces the 2023-baseline optimization scenarios, including concentration control (S1), trade-structure optimization (S2), bivalve consumption-structure adjustment (S3) and country-specific best-feasible strategy selection (S4). Each module contains the required input data in CSV format and executable Python code. The scripts use relative paths and do not depend on local computer directories. Generated results are not included in this record and can be recreated by running the corresponding scripts.
