The recreational parks of Lima city are green areas where diverse species of animals and plants live. These are also recreational areas located in the Rímac river basin. The GPLM (Gambella People's Liberation Movement) considered were the Bosque 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), Leyendas (12º07´14´´S, 77º05´12´´O) and Kennedy (12º07´18´´S, 77º01´49´´O). The present total of lead in the soils constitute a potential danger to the health of the inhabitants and users. The objective of this investigation was to quantify the total lead content at the GPLM soils. Identification samplings, physical (texture) and chemical (pH, electric conductivity, organic matter, CIC) analysis were performed for soil samples of each park. Those parks that showed contamination of lead were subjected a detailed sampling with additional total lead analysis. The mean values of total lead 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 that allowed by the Environmental Quality Standards (ECA-Emission Control Areas)-Peru: 140 ppm). In park Leyendas was determined that eight of the 98 hectares were contaminated (234.5 ppm Pb) and Huachipa Zoo 0.7 of 11 hectares were contaminated too (266 ppm Pb), while Kennedy Park did not exceed the ECA (56 ppm Pb).

Tello Lily has her expertise in soils and passion in improving the quality of them. Her doctoral research is being done in recreational parks in Lima (Peru) and lead. She has developed "assisted phytoextraction" techniques for lead in greenhouse and park bioassays. To achieve efficient phytoextraction she used mycorrhizae and EDTA. She has 20 years of experience as a professor in soils. She teaches Geology, Edaphology and Geomorphology courses at National Agrarian University in Lima, Peru.
