World's Most Toxic Places

The Aral Sea, located in Kazakhstan, Uzbekistan, was one of the world's four largest lakes until the waters that fed it were diverted for Soviet Union irrigation projects. By 2007, the Aral Sea shrank 90% and split into four basins.

Toxic chemicals from weapons testing, industrial projects, pesticides, and fertilizer have runoff and are swept by winds into surrounding areas. People nearby suffer from cancer, lung disease, digestive disorders, antibiotic resistant tuberculosis, liver, eye, and kidney disorders, and unusually high mortality rates. Water from the lake and has a higher salinity than sea water, with levels from what remains of the South Aral measured in excess of 100g/L versus sea water salinity of 35 g/L.

La Oroya is a mining town located in the Peruvian Andes. Since 1922, those living in La Oroya have breathed in toxic emissions and lived in toxic waste created by the poly-metallic smelter plant owned by Doe Run Corporation. La Oroya is home to the world's most critical levels of air pollution and the highest lead blood levels known to any children on the planet.
99 percent of the children in La Oroya have blood levels which exceed acceptable limits to qualify for lead poisoning.
Dzerzhinsk is located in Nizhy Novgorod Oblast, Russia along the Oka River, about 250 miles east of Moscow. Once Russia's primary chemical weapons production site, Dzerzhinsk is now home to approximately 300,000 tons of chemical waste dumped between 1930 until 1998. Life expectancy for men is 42 years and 47 years for women, compliments of dioxins, sarin, leeisite, sulfur mustard, hydrogen cyanide, phosgene, lead, phenol, and other chemicals. Dzerzhinsk is the most chemically polluted place on Earth according to the Guinness Book of World Records.
The Matanza-Riachuelo River in Argentina is 64 kilometers long and home to over 3.5 million people. The Matanza is filled with illegal sewage pipes draining directly into the river. Along Mantanza-Riachuelo's banks are 13 slums and open garbage dumps. Strong odors are released from chemical residue and methane gas.

The Kabwe is a mine located in Zambia and was long ago rendered one of the most toxic places on Earth. Once reserves of lead, zinc, silver, manganese, cadmium, vanadium, and titanium were extracted, heavy metals remained behind. Tailings from the mine, primarily zinc and lead, found their way into water supplies, affecting nearly 210,000 people.
Karachay is a small lake in the Ural mountains in Western Russia. It is home to a nuclear waste dumping site so radioactive it has been declared the most polluted place on the planet. During the early 1950s, the Soviet Union began dumping radioactive waste into Lake Karachay. Many years later, the Worldwatch Institute on nuclear waste rendered the area "the most polluted spot on Earth." Radiation levels at the lake are so high that one hour of exposure is considered lethal.
The accumulated levels of radioactivity are around 4.44 exabequerels (EBq) with 3.6 EBq of Caesium-137 and 0.74 EBq of Strontium-90. The 1986 Chernobyl disaster released between 5 to 12 Ebq of unconcentrated radioactivity.

Radioactivity in the ground water around Lake Karachay has migrated several kilometers.
