heavy metals such as mercury, copper, arsenic, chromium And pesticides such as DDT or polychlorinated biphenyls (PCBs)... all these are responsible for causing biomagnification as they will make their way into the food chain and then are incorporated into soil and water which are taken up by plants and animals...

Any two substances that are responsible for causing biomagnification are DDT and Toxaphene etc.
When the amount of toxic chemical increased in the food chain considerably it causes a lot of harm and spoils the food chain as well.
Pesticides can be consumed by human beings and the effects can be seen for ages and people may suffer. This is why most of them like DDT is banned.
