Recently, after the first registration of intoxication on 21 August 2018, the cases of contamination caused by the activities in the industrial zone intensified causing illnesses to several people including a high number of children. The state-owned company ENPA is one of the main responsible actors of the recent toxic contamination together with other companies like Gasmar and Oxiquim [20, 21].
Research on the contamination in the Puchuncavi zone [14] already had that “at the end of the 1980s, pioneering studies indicated that the toxic agents in the Puchuncavi air posed risks for the quality of life" and emphasized the lack of mitigation. This led to the declaration of Puchuncavi as a Saturated Zone for particulate matter (PM) and sulfur dioxide (SO2) in 1993, a condition that continues to exist today [18, 14]. The Chilean Medical Union Association recently requested the government to declare a health emergency in the area [15, 18]. Currently, there are more than a thousand people intoxicated, including two police experts who were examining the area. However, up to today, the acute intoxication continues [18].
In the following days in September and October, schools closed and social actions and protests increased in the region. However, the protesters faced an unusual amount of force with water cannons, rubber bullets and tear gas from the special forces and navy [12, 18].
Small-scale fisher people of the region, who are losing their resources due to contamination, have been an important part of these protests. Already in 2016, they had declared the polluting activities of ENPA and asked for mitigation claiming that in two years the company destroyed the entire flora and fauna damaging irreversibly the sea and the artisanal fisheries [6, 7].
Soon after the march against contamination and chemical intoxication, one of the leaders of the syndicate (Union of Fisher People) Alejandro Castro has been found dead on 4th October 2018 [1, 9, 18]. Even though the Chilean Government first claimed that it was a suicide, there are lots of evidences that he was receiving threats and his comrades and family claim that is must be an assassination. The police confirmed that he was receiving death threats [9] and the Congressman Latorre called for the revision of the cameras on the location where Alejandro was found dead [10, 18].
Alejandro’s case comes in the wake of the Macarena Valdes case, who was found dead in 2016, and the Mapuche leader Nicolasa Quitreman, found dead in 2013. All cases were first labelled as suicides. However, a police investigation later recognized that Macarena did not commit suicide [11, 18].
The Escazú Agreement, which has been initiated to protect environmental activists [16,18], seeks to improve environmental governance through access to information, participation and environmental justice. This agreement was initially proposed by Chile, among other countries, and is now sponsored by the United Nations, through ECLAC, in line with the 10th principle of the Rio Declaration. Unfortunately, Piñera’s administration recently dropped out of the Escazú agreement. However, Alejandro’s assassination is another grim reminder of the urgent need to protect environmental defenders [18].
