From a toxicological perspective, the introduction of non-native species through ballast water can lead to significant ecological disruptions, which may include the release of natural toxins or the introduction of toxin-producing organisms. For example, certain harmful algal blooms can be exacerbated by non-native species, leading to the production of toxins that affect marine life and human health. Understanding the chemical and biological processes involved in these scenarios is crucial for risk assessment and management.
