Weegy: Many other substances are released into the air by chemical manufacturers, municipal incinerators, and even fireplaces. They are called "point source" air pollutants and can be extremely caustic and threatening to health. [ [ The Union Carbide disaster at Bhopal, India, is an example of a point source air pollutant. Other examples are the Three Mile Island and the Chernobyl nuclear power plant radioactive discharges.
Many chemical manufacturing plants emit air pollutants through their manufacturing processes. These may not be quite so dramatic as the Chernobyl and Bhopal discharges, but in the long run, exposure to some of these chemicals may be just as deadly. These pollutants, including dioxins and furans, can be lethal in minute doses, and they do not remain in the air forever. When they settle, a few yards or hundreds of miles away, they can be absorbed into the groundwater and begin the slow process of moving up the food chain until they reach our dinner table. Many of these chemicals accumulate in the body and may be the cause of various cancers.
Chemicals such as benzene, chlordane, xylene, toluene, lead, mercury, cadmium, selenium, arsenic, tetrachloroethylene, chlorophenols, dioxins, furans, and hundreds of others are present at detectable levels in human body tissue. There is not a person alive today who will not have some synthetic substance show up in the blood if it is looked for.
These substances tend to collect in the fatty tissue of the body. Many are potent carcinogens (agents that cause cancer) and mutagens (agents that cause birth defects). They may be slowly ticking time bombs waiting 20, 30, or 40 years after entry to confront the body with a cancer of some type. They may be silent cofactors in causing disease, along with well-known cancer-causing substances like tobacco, asbestos, and others. Their effects may not even show up until we have children with birth defects such as spina bifida, cleft palate, Down's syndrome, or heart ...

Here are 8 environmental health hazards that have a substantial negative impact on humans in several ways:
1. Chemical Exposure: Harmful chemicals can lead to cancer, birth defects, and neurological disorders.
2. Air Pollution: Poor air quality causes respiratory issues, heart disease, and stroke, contributing to a third of deaths from related diseases.
3. Climate Change: Altered disease patterns and increased natural disasters harm communities' health.
4. Microbial Diseases: Bacteria and viruses cause food poisoning, influenza, and tuberculosis.
5. Limited Healthcare Access: Lack of medical care prevents adequate treatment.
6. Infrastructure Problems: Inadequate sanitation and unsafe housing lead to health problems.
7. Contaminated Water: Poor water quality results in illnesses like diarrhea and cholera.
8. Global Environmental Concerns: Deforestation and overfishing have far-reaching health impacts.
