The Salton Sea is a large lake located in the southern portion of California. Originally formed as a result of flooding from the Colorado River, the Salton Sea has become increasingly saline and polluted over time. This has led to a number of environmental issues, including the growth of harmful bacteria that produce foul-smelling odors. The smell of the Salton Sea has been described as "rotting fish" and "sewage," and it can be especially strong during hot weather.

In addition to the unpleasant odor, the Salton Sea's pollution has also led to a number of health problems for nearby residents. The most common health issue is asthma, which is made worse by the air pollution from the Salton Sea. Other health problems that have been linked to the Salton Sea include bronchitis, emphysema, and heart disease.

The pollution of the Salton Sea is a serious environmental issue that is having a negative impact on the health of nearby residents. There are a number of steps that need to be taken to address this issue, including reducing the amount of pollution entering the Salton Sea, cleaning up the existing pollution, and restoring the Salton Sea to its natural state.
