Summary
Abalone and sea cucumbers contain beneficial trace elements like iron and zinc. However, environmental pollution can lead to high levels of harmful heavy metals, so caution is advised when consuming them.
Area of Science:
- Marine biology
- Analytical chemistry
Context:
- Abalone and sea cucumbers are valuable seafood sources.
- Trace element analysis is crucial for assessing nutritional value and safety.
Purpose:
- To determine trace element concentrations in abalone and sea cucumbers.
- To optimize an analytical method for multi-element determination.
- To assess the impact of environmental pollution on seafood safety.
Summary:
- An orthogonal test design and ICP-AES were used to determine 15 trace elements in abalone and sea cucumbers.
- The optimized method is sensitive, accurate, rapid, and environmentally friendly.
- Both seafood types are rich in beneficial trace elements but can accumulate heavy metals due to pollution.
Impact:
- Provides data on the nutritional profile of abalone and sea cucumbers.
- Highlights the potential health risks associated with heavy metal contamination in seafood.
- Emphasizes the need to monitor seawater pollution and its effects on marine ecosystems and human health.
