Some of the types of heavy metals commonly found in seafood include:

1.    Mercury 
Mercury is a heavy metal commonly found in fish and seafood. Predatory fish like sharks, swordfish, and tuna tend to contain higher concentrations of mercury as they are at the top of the marine food chain.

2.    Lead 
Lead metal can be found in some types of seafood due to environmental pollution. Although lead is generally found in low levels, long-term exposure can have adverse health effects.

3.    Cadmium
Cadmium is a heavy metal that can be found in fish and seafood. Fish such as scallops and deep-sea crabs have a higher potential to contain cadmium.

4.    Arsenic

6.    Nickel 
Nickel can be found in low levels in seafood due to environmental exposure.

It is important to remember that most seafood contains low levels of heavy metals that do not harm human health if consumed within safe limits. 

However, certain types of seafood that are at the top of the marine food chain or live in contaminated waters have a higher potential to contain higher concentrations of heavy metals. Therefore, it is important to choose seafood that is lower in heavy metal risk, limit consumption of riskier types of seafood, and adhere to consumption guidelines recommended by health authorities.
