I think you need to read his book before making such statements. Its like judging the bible be listening to what some fundamentalists have to say.

Not all studies are to be trusted, this I know, but there are plenty of studies that if you read the data you can come to very rational conclusions in regards to mercury toxicity.

Living chlorella, does pick up heavy metals from the environment it grows in. This is really not surprising as anything living seems to accumulate things like mercury. This does not mean that it will chelate mercury after it has been dead and broken open. That is a ridiculous assumption. I might as well assume eating fish will chelate mercury from my body since fish very efficiently absorb mercury from their environment.

Consider the sources, chlorella is a big money maker, that failed to be an efficient source of food/protein that it was originally intended for.
