Background: Mining activities can produce large amounts of heavy metals that are discharged uncontrollably, causing widespread ecosystem pollution. Heavy metal pollution is a serious problem, as heavy metals are toxic and non-degradable, polluting air, water and soil. Although some heavy metals are considered essential for normal physiological functions, concentrations that exceed the prescribed limits can have negative impacts on human health and biota. Exposure to heavy metals can cause toxicity to various tissues, organs and systems such as circulatory, respiratory, endocrine, immune, nervous, urinary and reproductive systems. Due to the differences in toxicity of heavy metals, risk assessment is very important in environmental management. Objective: To describe the probabilistic simulation and sensitivity of health risks due to Nickel and Cobalt deposition around the mine using monte carlo simulation. Methods: The method used in this study was literature review. Data collection was done through searching online databases such as: Pubmed and Science Direct. The keywords used in the article search were "Heavy Metal Toxicity", "Heavy Metal Effects", "Heavy metal risk analysis" and "Monte Carlo Simulation". Inclusion criteria were quantitative or qualitative research, target population was heavy metals Nickel and Cobalt, published in the last 10 years (2013-2023) articles in English and articles in original, fulltext and open access. Exclusion criteria are articles that are not relevant to the topic of discussion. Results: 14 articles were found, of which 3 articles on diseases or health problems caused by nickel, 3 articles on nickel risk analysis, 5 articles on diseases or health problems caused by cobalt, 3 articles on cobalt risk analysis. Conclusion: The environment around the mine shows a high level of toxicity, caused by the presence of heavy metals. This can result in serious environmental pollution and pose a great threat to human health. Chronic exposure to heavy metals can cause various health problems, such as mutagenesis, carcinogenesis, teratogenesis, deformation and organ damage. [ABSTRACT FROM AUTHOR]

The results of Indonesian nutritional status study at the regency level in 2021 showed that Polewali Mandar Regency had the highest prevalence of stunting in West Sulawesi Province at 36% with the highest percentage of stunted toddlers being reported by Katumbangan Health Center (42.6%). This study aims to determine the most dominant risk factors for stunting in children aged 0-23 months. This study was conducted in the working area of Katumbangan Health Center with a case-control study. The number of samples was 236 infants (0-23 months) with a ratio of cases and controls of 1:1. This study used secondary data sourced form e-PPGBM application, then analyzed by odd ratio test and logistic regression on Stata. The results showed that CED in pregnancy (OR=3.142 with 95% CI, 1.122-10.072), LBW history (OR=5.963 with 95% CI, 1.251-56.216) and exclusive breastfeeding (OR=2.099 with 95% CI, 0.984-4.613). The dominant risk factor for stunting in children aged 0-23 months, namely LBW history (OR=5.092 with 95% CI, 1.08-23.94). It is recommended for mothers to put more attention to the fulfillment of nutrition during in order to reduce the risk of LBW and also to assure that children nutritionl intake are adequate to their needs during the golden period of growth, especially infants with LBW.
