A/HRC/45/12/Add.4 Toxicological Studies, as well as the need for prior authorization from the Renova Foundation, together with CT-Saúde, for their dissemination. The only prohibition for disclosing the data was and still is for the contracted company. 73. Therefore, it should be clarified that no ownership clause allows the Renova Foundation to omit the studies' data. What is forbidden is that the company hired for its preparation makes its disclosure without an evaluation by relevant bodies. 74 It should also be stressed that all remedial actions must be approved by the CIF, which is governed by the principles of legality, impersonality, and morality, with no interest in benefiting or harming contracted consultants. Protecting the most vulnerable 75. The Rapporteur mentions Barra Longa deposition of waste in an area belonging to a peripheral neighborhood with a predominantly Afro-descendant population as a possible case of racial discrimination: “Low-income families, including Afro-Brazilians, suffered disproportionate exposure to dust and heavy metals in mud heaped in Barra Longa following the Mariana dam collapse by agents of the companies and the Renova foundation.” (page 12) 76. In this regard, it is important to mention that the CIF applied several sanctions to the Renova Foundation regarding the tailings management program present in the TTAC. It should also be noted that decisions on the location and disposal of waste follow environmental legislation, and the CIF does not endorse any discrimination, guiding itself by technical assessments. 77. About the protection of the vulnerable, it is recalled that the General Coordination for Occupational Health (CGSAT) of the Ministry of Health participated effectively in the technical meetings held during the visit of the Rapporteur, and informed him that it has been working continuously to promote the integral health of all workers, especially those most vulnerable, such as those exposed to chemical substances. 78. For this purpose, CGSAT has been strengthening the National Network of Comprehensive Attention to Occupational Health (Renast), structuring existing programs and developing new actions to promote health, prevent and monitor risk factors and injuries, to intervene in determinants of exposure to chemicals that interfere with human health. 79. Among the initiatives of CGSAT, the CAREX Brasil Project stands out, an international information system for elaborating an occupational exposure matrix whose objective is to estimate the proportion of workers exposed to carcinogens and support intervention actions in the territories. 80. The project is undergoing review and adjustments before the inclusion of new agents. However, its preliminary version demonstrated consistency, when analyzing the exposures to the pesticides Clorotalonil, Malation, and Glyphosate, to Asbestos, to Silica, to Benzene, and ionizing radiation. 81. Exposure to pesticides is an essential topic in the public health area, and a priority to CGSAT, which promotes various policies and programs aimed at agricultural workers, such as the National Policy for Comprehensive Health of the Rural and Forest Populations (PNSIPCF) and the Health Surveillance Program for Populations Exposed to Pesticides (VSPEA). 82. Furthermore, a registering and monitoring system for workers exposed to Asbestos in Brazil is in preparation, with the possibility of monitoring data in real-time. The platform is already at a very advanced stage and has the participation of several specialists and the Federal Public Prosecutor Office's support. 83. Regarding the rupture of mining tailings dams, CGSAT participates, together with the General Coordination of Environmental Health Surveillance (CGVAM), in several initiatives aimed at the care of the affected populations, intending to ensure the monitoring of the health 12
