TELLO, Lily; JAVE, Jorge  and  GUERRERO, Juan. Analysis of lead quantification in recreational park soils of the city of Lima - Peru. Ecol. apl. [online]. 2018, vol.17, n.1, pp.1-12. ISSN 1726-2216.  http://dx.doi.org/10.21704/rea.v17i1.1168.

The recreational parks of Lima city (GPLM) are green areas where diverse species of animals and plants live. These are also recreational areas located in the Rímac river basin. The GPLM considered were Bosque El Olivar (12º06´04´´S, 77º02´05´´O), Campo de Marte (12º04´06´´S, 77º02´29´´O), Pentagonito (12º06´01´´S, 76º59´35´´O), Huachipa Zoo (12º00´52´´S, 76º53´52´´O), Las Leyendas (12º07´14´´S, 77º05´12´´O) and Kennedy (12º07´18´´S, 77º01´49´´O). Lead presence in the soils constitutes a potential danger to the health of the inhabitants and users. The objective of this study was to quantify the total lead content in the GPLM soils. Samplings were performed for identifications, physical (texture) and chemical (pH, electric conductivity, organic matter, CIC) analysis in each park. Those parks that showed lead contamination were subjected to detailed samplings with additional total lead analysis. The mean values of total lead content in soils of the GPLM Bosque Olivar (170 ppm Pb), Campo de Marte (226 ppm Pb) and Pentagonito (159 ppm Pb) were found to be above those allowed by the Environmental Quality Standards (ECA-Peru: 140 ppm). At Las Leyendas park eight of the 98 hectares were contaminated (234.5 ppm Pb) and at Huachipa Zoo 0.7 0f 11 hectares were contaminated too (266 ppm Pb), while Kennedy Park did not exceed the ECA (56 ppm Pb).
