Man as an entity may in this manner change only his personality if the state concerns exclusively psychic and/or emotional processes. A body part which is far from equilibrium in a dissipathogenic state (the bifucation point at the thermodynamic branch) may survive by means of either returning to near-equilibrium or equilibrium, or self-organization into a neoplasm (cancer).

This seems to be important for preventing Hg intoxication. The main source of Se is marine food, which is subject to seasonal variation in chemical composition. Average amount of Se in cord blood was 100 g/1 in summer and 300 g/1 in winter. Differences in the concentration of Se and Hg depended on factors like dietary intake and age. Both blood and hair samples are good indicators of Hg level in the body. Seasonal variation in placental Hg content has also been reported by Niwelinski et al. from some rural areas in Poland [6].
