In reality, the negative role of industry on the environment is perhaps greater than any other factor. In our country, especially industrial establishments cause excessive pollution on soil and vegetation due to liquid wastes and water pollution. Water pollution increases the hardness of drinking water and even becomes rich in heavy metals, that is, “non-potable water”. Excessive use of fertilizers increases the salinity of the fields, as a result of which the area of unproductive agricultural lands expands. Detergents that are used more than necessary cause the reproduction of blue and green algae as they are given to lakes and rivers without being treated. It causes mass death in living things that feed on them. One liter of waste oil (such as cooking oil) that is not sent for recycling pollutes one million liters of clean water.
Effect on Human Health
Diseases such as cholera, typhoid fever, paratyphoid, dysentery, hepatitis, diarrhea, polio and malaria are unfortunately caused by unhealthy water. In parallel with the need for water resources all over the world and in our country, the pollution on these resources, which are limited, is increasing.
According to the World Health Organization (WHO) data, approximately 25 thousand people die every day in the world due to unhealthy water use. Deadly diseases such as typhoid fever, cholera, and dysentery are transmitted to humans through water, and human health is deteriorated by chemical substances such as ammonia and nitrite as a result of contamination of well waters by waste water and agricultural fertilizers. In addition, poisoning caused by pesticides reaching groundwater can also lead to human deaths.
Effect on Nature
Chemicals and organic compounds in wastewater cause a decrease in the amount of dissolved oxygen in the water. This increases the mortality rates of aquatic plants and animals. Such waters have a darker color and a foul odor. In fact, in some lakes or streams, as a result of excessive pollution, the living life has come to an end and islets formed from wastes have been formed.
Radioactive wastes are becoming more and more dangerous day by day. These wastes are stored under certain conditions, but in some cases, they accidentally or unconsciously mix with nature and groundwater. Radiation emitted by radioactive wastes causes cancer and mutations in living things.
