 | | Before 1958, arsenic levels in the water of Antofagasta averaged 90 [micro]g/L. After the introduction of the Toconce River as the main water source, the mean arsenic levels during the period 1958-1970 rose to approximately 860 [micro]g/L. In 1970, the city installed an arsenic-removal plant for this water supply. |
 | | Between 1950 and 1996, Antofagasta experienced an 86% decline in the late fetal mortality rate, an 81% decline in the neonatal mortality rate, and a 92% decline in the posmeonatal mortality rate. |
 | | Although both Antofagasta and Valparaiso experienced substantial improvements in their overall infant mortality rates over the study period, the pattern of infant mortality for these two communities was quite different before the 1970s. |
