>>1488762>The concentrations of Hg in the substrate and in the mushroom were evaluated by AAS. The range of the accumulation factor was found to be 65-140, i.e., very marked. This finding suggests that the cultivation of P. ostreatus on substrates containing Hg from industrial and urban wastes could involve possible risks to human health.Did you even read the study?
They added mercury to an artificial substrate to mimic the effects of industrial waste on growing mushrooms, paper does not contain industrial waste levels of lead or mercury, if they did they would not be safe to handle.
>The Cr concentration in all plant species exceeded the standard for vegetables. The BAF values followed the heavy metal concentrations. All plant species have a low potential for accumulating Pb and Cr. The edible plants in this study area might cause health hazards to consumers from As, Pb, and Cd contamination.These are plants grown next to a LANDFILL, do you understand why it's disingenuous to use landfills as a proxy for inocuous human waste such as paper with glue and ink on them?
>Plant uptake of organic chemicals is an important process when considering the risks associated with land contamination, the role of vegetation in the global cycling of persistent organic pollutants, and the potential for industrial discharges to contaminate the food chain. Non-specific junk
Next time try actually applying some critical thinking
