Naphthalene and benzyltoluene are compounds considered interesting for chemical hydrogen

storage. In order to get an idea of their effects on the environment, an analysis of the distribution

of the contaminant among water, soil, and biota is desired. Consider a spill of $200kg$ of each of

these compounds into a lake of ${1\mathrm{.}10}^7{m}^3,$ estimating that the biota concentration in the lake is $0\mathrm{.}006$

$k\frac{g}{m^3},$ and the mass fraction of soil with water exchange capacity is of the order of $1\%($water

mass$/$soil mass$)$ and use the group contribution theory. Based on these results, could you choose

one of these components as the "most sustainable" one? Do you need to consider other aspects?

In case of a positive answer, please specify some of them.
