Niveles de metales pesados. Huertos urbanos en Bogotá Colombia

Urban Farm DB summary

This study sampled soil, irrigation water, and lettuce from 49 urban gardens across 13 Bogotá localities to quantify heavy metals (Pb, Cd, Cr, Ni, As, Hg), finding that all detected concentrations remained below national and international health-based guidance values.

Only numbers and their conditions are stored, as structured data — never the source's own sentences. Metric and condition names stay in English, as coded.
