Bioremediation in Latin America: Current Research and by Analía Alvarez, Marta Alejandra Polti

By Analía Alvarez, Marta Alejandra Polti

The e-book compiles an replace information regarding the country of bioremediation in rising Latin American international locations. many of the studied areas are websites that suffered a long time of pollutants through agrochemicals, heavy metals and commercial waste because of the loss of regulate by means of executive laws. Such is the case of Northern Argentina, the place have been illegally deposited over 30 tn of out of date organochlorine insecticides in 1994. The content material has concentrated within the use of local organisms (from micro organism to vegetation) as a practicable strategy to the matter of toxins, utilizing inexpensive and robust concepts, socially good approved and applicable from the environmental perspective. during this context, degrees of pesticide present in the Latin American inhabitants are knowledgeable. It was once additionally displayed as a multidisciplinary procedure in response to issues of a various team of researchers (biochemists, biologists, chemical engineers and geneticists) a few worldwide challenge, facing particular situations of analysis, as a way to undertaking their findings to around the globe. during this regard, researchers offer their findings to regulatory sectors, whom can make applicable decisions.

3 33 Breast Milk Persistent organic pollutants are accumulated in the fat of the different tissues due to its lipophilic properties. These compounds are translocated and excreted through breast milk during lactation. Therefore it is an important route of exposure for infants during the first months of life. Early exposure to POPs during the neonatal period may affect child neurodevelopment and growth. The concentrations of these compounds in human milk are a nice indicator of environmental contamination (Díaz-Barriga et al.

2012). Although adipose tissue levels have been preferentially used as an indicator of chronic human exposure to organochlorine contaminants, serum levels have been adopted in epidemiological studies as a less invasive and more practical alternative (Díaz-Barriga et al. 2003). In this document, we present a data collection of exposure to OCP and PCBs in adipose tissue, serum, and breast milk in Argentine general population and population from other Latin American countries, in order to evaluate the degree of exposure to POPs and compare the levels found in inhabitants of different regions.

In Latin America, Mexico had reported the highest number of studies in human adipose tissue. Levels of DDT and its metabolites in human biological media from different communities of Mexico had been assessed by Díaz-Barriga et al.
