Previously, Brazil was home to one of the biggest garbage dumps in the world in Brasilia. It is one of the most polluted places on earth. It recently closed after nearly 60 years, where it processed over 1,000 tons of garbage every single day. Unfortunately, this closure hurts locals in the area, who were previously using the dump to scavenge as a way to survive and make an income.
Luckily, the regional government announced they’ll hire scavengers to work in the recycling center. This is one benefit of the dump’s closure. One of the biggest rubbish dumps in South America has closed in Brazil after almost 60 years. Additionally, The larger urban areas of São Paulo, Rio de Janeiro, and Brasilia suffer from substantial ozone issues because both acetaldehyde and nitrogen oxides are significant contributors to photochemical air pollution and ozone formation (BBC).
Deadly heavy metals are found in Bald Mountain in Indonesia. These metals came from vast quantities of mercury used to separate gold from the land. Unfortunately, so much mercury was used turned the island into a toxic wasteland. This threatened marine life, public health, agriculture, and the people in the area.
What initially seemed like a great income source for locals quickly became a source of toxins. Another negative impact included destroying a sacred mountain with irreversible damage. Indonesia is today the world’s twentieth most polluted country. Air pollution shortens the average Indonesian’s life expectancy by 2 years, relative to what it would be if the World Health Organization (WHO) guideline was permanently met. (Asia Times).
Tashkent is one of the most polluted places on earth. It’s more dangerous for people who are sensitive to smog and pollution, or who have allergies. A lot of this pollution comes from smog from the factories, industrial areas, and power plants that burn coal and other material that leaks into the air.
In 2019, Tashkent came in with a yearly PM2. 5 average reading of 41.2 μg/m³, a high reading that placed it into the ‘unhealthy for sensitive groups’ bracket, which requires a PM2. 5 reading of anywhere between 35.5 to 55.4 μg/m³ to be classed as such. This is extremely hazardous for public health and people living in the area since they have constant exposure to smoke and smog (IQ Air).
Delhi is, reportedly, one of the most polluted areas on the planet.Polluted smog hovers over the city of Delhi in India in the wintertime. Garbage fills up three landfills every single year, and these dumping sites are proven to be a safety hazard for locals living in proximity to the garbage dumps. Previously, North Delhi’s dump Bhalswa caught fire and emitted smoke into the air.
It took over four days for officials to calm the fire down. By that time toxic pollutants had already leaked into the air. The fumes, plus the garbage and smog create a toxic concoction that’s harming the lives of many locals living in Delhi and the neighboring towns and cities (Scroll).
Because of growing industries in Ghaziabad, it’s become one of the most polluted areas in the world. Even though growing industries seems like a good thing, it’s having the complete opposite effect on the environment. Growing industries means more toxic dumping and waste in the environment.
Additionally, there’s an increase in traffic from cars and motor vehicles, making it incredibly toxic. Fumes emitted from these vehicles, in addition to traffic, are adding to the low level of air quality in this city. Smoke stacks are also seen in the city, which emits an array of toxic fumes all on their own (Earth).
Even though the city of Bahawalpur is famous for its pottery and carpets, it’s also considered to be one of the most polluted areas on earth. The city has experienced many bouts of unhealthy air. They’ve also had harmful readings that are beyond what’s deemed safe by national standards.
As we’ve seen in many other cities around the world, children are constantly suffering from respiratory diseases. This is a result of the air quality they’re living in. This is extremely harmful to their health, and will only worsen with time (Research Gate).
La Oroya, Peru is a mining town in the Peruvian Andes and the site of a poly-metallic smelter since 1922. The area is highly contaminated by mining waste and by dust and acidic fumes from the smelter. Surveys have confirmed high blood lead levels in children and sulfur dioxide levels also exceeded WHO limits.
Unfortunately, it’s notorious for being one of the most polluted areas on earth. The local government has been unable to clean up the pollution caused by the metal smelter in La Oroya. It is the major contributor to the pollution problem. This mining town emits acidic fumes directly from the smelter into the air. Children now have extremely high levels of sulfur dioxide and lead in their blood as a result (Bilaterals).
Many people want to swim in the sea flanking Manila, but unfortunately, the reality is that the sea is extremely polluted by toxic waste from the city. It’s one of the most polluted areas in the world and is full of toxins from house sewage, industrial waste, and commercial establishments that use the sea as a toxic dump.
Locals are attempting to clean up the area and make it less toxic than it already is, even though this feat seems impossible. It’s going to take a lot of effort before the area sees any change or lessening of toxic chemicals. Toxins in Manila have accounted for more than 27,000 deaths. Considering this is entirely preventable, it’s a shame that so many people are suffering from it (2FrenchinManila).
Due to its location, Baghpat is, unfortunately, one of the most polluted places in the world. It’s situated in a spot that’s hit by north-westerly winds carrying stubble smoke. This smoke comes from the paddy fields of Punjab. Additionally, it contributed to 25% of pollution in a recent winter.
Because there hasn’t been any action plans to try and decrease the amount of pollution, its been accumulating over the years and has now reached a crisis level. This is true for many of the cities across India. Unfortunately, Baghpat is just one of them (Hindustan Times).
We’ve seen Delhi on this list as one of the most polluted areas in the world. But Mumbai has also made the list. Mountains of garbage tower along the outskirts of the city. Luckily, the Prime Minister is attempting to tackle this problem and is implementing waste treatment plants. Some of the mountains of garbage tower up to 18 stories high.
Many locals in the area use the garbage waste dumps as scavengers to try and sell products they find. Pollution in Mumbai also stems from overpopulated highways, unpaved dusty roads, burning of garbage, and emissions from local industries (BBC).
The Citarum River in Indonesia is 225 kilometers in length and runs through villages that use it for drinking, washing, cooking, and bathing. Over 25 million people are living in its basin, hence the reason it’s so polluted. The lack of regulations and poor sewage and waste system contributes to the polluted waterways.
Additionally, thousands of waste-producing industries line the river’s waterways, which use it as a dumping system. In addition to this, the river accumulates waste from agricultural factories and fisheries (Austro Indonesia).
Pasig River connects Laguna Bay to Manila Bay. Even though we’ve seen the waterways of Manila as some of the most polluted in the world, the Pasig River also makes the list. Plastic waste flows into the river’s mouth, which is harming locals that live in proximity to the river. Many environmentalists are attempting to clean the river through beach cleanups and brand auditing.
This is an attempt to slow down the heavy waste responsible for a majority of the pollution. This river alone accounts for more than 63,000 tons of plastic entering the ocean every single year. And that’s just one river (Business Mirror).
Another major Indian city makes the list, and this time it’s Kolkata. The Dhapa landfill, located in the city, is facing a crisis of coping with the daily burden of waste from locals in the city. It’s too much to take in, and more waste is being produced than can be dealt with. The only solution is to slow down the waste consumption in the city of Kolkata. Once this happens, the landfill can process what’s already there. The Dhapa has a bit of history behind it since it was created in 1941 under British rule.
A garbage train would travel along the city’s main roads collecting garbage, and then bringing it to the landfill. It is no surprise that the waste in the 40s was much less than the waste we’re seeing today. Today, we’re seeing over 5,000 metric tons of waste every day, with over 4,000 tons of it getting dumped into landfill. It’s also towering at a dangerous height of 50 feet, and at this point is unable to take in any more waste (Swachhindia).
Another area of Ghana, Accra, sees heavy acidic gusts of smoke blowing across the city. It’s home to the Agbogbloshie dump, which we’ve previously seen on this list. But the city of Accra itself is also home to tons of waste and toxic air. Ghana alone is one of the most polluted countries in the world, and a lot of it, unfortunately, comes from e-waste.
Many people living and working in Accra, and Agbogbloshie, see back problems, burns, and infected wounds solely from the pollution they’re constantly surrounding themself with. Luckily, Accra, became the first major African city to join the BreatheLife campaign. Accra is the first pilot city of the Urban Health Initiative, supported by UN Environment’s Climate and Clean Air Coalition. (Bloomberg)
