Meta-analysis data on the effects of metals on weight, number of neonates and body metal content in invertebrates

Data:
- Coordinates used for creating a world map showing the localization of contaminated sites from which organisms are sampled);
- Computed datasets (weight, number of neonates, and body metal content) that were used in the meta-analysis;
- Not computed datasets (weight, number of neonates,and body metal content). These datasets include all datapoints before transformation for analysis with computed data.
