Is it possible to produce a negative impact on a body by placing a biologically harmful substance (e.g., lead, bleach, etc.) on the receiver pad?

We do not know for sure, but it is possible. Some people think that our body takes what it needs, but some people think otherwise. We recommend to keep harmful substance away from the receiver coil.
