Child risk assessment of selected metal(loid)s from urban soils using in vitro UBM procedure

In city agglomerations significant pollution results from fossil fuel combustion from heat and power plants, transportation, and boilers in households. In this context, pollution from recalcitrant, environmentally accumulative metal(loid)s can be a critical human health risk. In day-care centers, pl...
