"Toxins in fish from polluted water can also be a source of problem. Many of these toxins comes in the form of metals and may even contain mercury. The fish at the top of the food chain are those likely to be contaminated. However, plants that are not consumed will constitute no problem however you still need to run some background checks to ascertain what you are putting in your soil." - @kenhudoy

Great read. Thanks for sharing. Upvoted.
