The 10 Most Polluted Regions - Current Status in the 2020s
As of the 2020s, the situation in the most polluted regions remains critical. Below are details on some of the most affected areas:
Vapi, India
The problem of industrial waste management in Vapi remains unresolved, with lead, cadmium, and hexavalent chromium continuing to pollute water sources. Chemical plants still discharge harmful substances, and health issues among residents are on the rise. Studies in the 2020s show pollutant levels exceeding permissible limits by tens of times, leading to a high incidence of cancer and skin diseases.
Chelyabinsk, Russia
The nuclear contamination in Chelyabinsk remains unresolved. Radioactive substances like cesium-137 and strontium-90 continue to contaminate the soil and groundwater. Reports from the 2020s show that residents' radiation exposure levels remain high, posing long-term health risks.
La Oroya, Peru
The metal smelter owned by the U.S. company Doe Run continues to emit lead and arsenic into the air in the 2020s. Blood lead levels in local residents remain high, especially among children, who suffer from severe health issues. A 2020 report found that about 90% of children suffer from lead poisoning.
Tianjin, China
Rapid industrialization in Tianjin continues in the 2020s, and sulfur dioxide and nitrogen oxides remain major pollutants. Despite government efforts to curb pollution, PM2.5 levels remain high, causing an increase in respiratory diseases among the population.
Kabwe, Zambia
Kabwe's lead contamination remains critical. Soil lead levels remain extremely high, and in the 2020s, blood lead levels in residents are far above the safety limit. Children are particularly affected, suffering from neurological disorders and behavioral issues.
Hazaribagh, Bangladesh
Hazaribagh remains a hub of leather industry pollution, where chromium and other harmful chemicals continue to be discharged into rivers without proper treatment. Hexavalent chromium, a known carcinogen, is causing skin diseases and respiratory illnesses among residents. Reports from 2020 show water contamination levels hundreds of times above safe limits, with significant health impacts on the population.
Ogoniland, Nigeria
Oil spills in Ogoniland remain a serious issue in the 2020s, with oil companies like Shell continuing to contribute to soil and water contamination. Recovery of the area is expected to take decades, with drinking water contamination and associated health issues such as respiratory and skin diseases becoming more prevalent.
Citarum River, Indonesia
The Citarum River is still one of the most polluted rivers in the world in the 2020s. Textile industry wastewater containing lead and cadmium continues to flow into the river, contaminating drinking water. The levels of hazardous chemicals exceed WHO safety standards by several hundred times, and the pollution affects local agriculture and the food chain.
Agbogbloshie, Ghana
Agbogbloshie remains one of the largest e-waste dumping sites in the world, and the situation has not improved in the 2020s. Electronic waste from Western countries is illegally dumped here and burned, releasing harmful substances like lead and mercury into the air and soil. Local workers, many of whom are children, are exposed to severe health risks, with respiratory diseases and cancer rates increasing.
Mexico City, Mexico
Mexico City continues to struggle with severe air pollution in the 2020s. Major pollutants include nitrogen dioxide (NO2) and sulfur dioxide (SO2) from vehicle emissions and factories. PM2.5 levels often reach dangerous levels, particularly during the dry season, and the pollution significantly impacts respiratory and cardiovascular health. Although the government is strengthening environmental measures, the high population and dependency on automobiles make a complete resolution difficult.
