Pollution in the Yangtze River

Reasons For Pollution

As the air around the cities situated on the Yangtze River has incredibly low quality, whatever chemicals such as CO2 are dissolved into the river

This decreases the quality of living for any Marine life inside

chemical output of waste can pollute the river and damage the ecosystem inside of it.

This makes it difficult for fish and other marine life to reproduce and start the next generation in the river.

This causes population to decrease dramatically

Reduced population decreases the health of the ecosystem

Chemical makeup of the water changes with a severe increase of certain anions and some cations with levels of mg/L well above what should be in natural rivers worldwide.

Infrastructure and collateral pollution (collateral pollution being the unavoidable waste product into the river)

The collateral pollutIon is likely higher in the Yangtze River, as more people are likely to output more waste product into the river, however, this is likely not a significant amount compared to avoidable waste products being dumped into the river.

The River floods into populated areas, and can bring materials from urban environments into the Yangtze River in large quantities.

Meets average levels

The relative oxidizing power of the Yangtze River (ORP) was shown to have all negative values, meaning that the marine ecology is possibly being reduced severely

Because of acid rain, the pH of the water increases dramatically as the river proceeds downstream.

The pH of the water even before polluted areas is already relatively high, with 8.3-9.3 pH

Methods to Resolve Issue

Some organizations such as WWF (world wide fund for nature) have agreed to contribute to cleaning and aiding the regrowth of the river

The government of China has allowed and will contribute to the cleaning of the Yangtze River

Some propose that a dam be build to protect homes against flooding.

they will be released in certain periods of time to account for fish breeding seasons.

Despite the high acidity of the river, it also appears to have a high buffering capacity

Having a high buffering capacity means that the
river can sustain higher acidity than normal rivers, however, this trait should not be exploited and/or pushed for the sake of the ecosystem and conditions of the river, and those who rely off of it
