Presence of Toxic Metals in Fluids and Tissues of People of Xochitlan,Hidalgo,Mexico

摘要

To determine levels of metal bioaccumulation(Cd,Cr,Pb and Al)in weaves and corporal fluids of the inhabitants of Xochitlln,Hidalgo,has been the objective of this study.With a view to realising valuations of risk and probable damages to the health of its settlers,the study with a sociodemographic characterization began,with settlers between 6 and 90 years of age.As exclusion criterion were considered,congenital malformations,immunosuppressive sufferings and less than five years of residence in the locality.An inverted population pyramid appeared;of a total of 1947 inhabitants,the population between 10 and 19 years occupies the center of the pyramid,that thins in the ends of the life(5>X>60 years).A methodology,combined with the established by the ATSDR and the EPA has seted out and adding an instrument of survey(clinical anamnesis)for the characterization of individuals and populations with ample clinical approach.Of the interrelation of flowed and woven metal concentrations in,with aspects of environmental risks it will be possible to be poured off a present,retrospective situational diagnosis and a vision to future,on the behaviour of the contamination and its impact in health factors.The evaluated metal bioaccumulation was present in all the fluids and weaves of the settlers selected between 6 and 90 years of age.One has been a probable relation between these results and those of previous studies of metal accumulation in waters,grounds and cultures.
