EduGreen states that water pollution affects humans by causing health problems, particularly water-borne diseases. Sources of water contaminants include pesticides, sewage, nutrients, synthetic organics and acidification of surface water.Know More
Contaminants and chemicals in drinking water cause adverse effects on health, explains EduGreen. These contaminants include arsenic, lead, petrochemicals, heavy metals, chlorinated solvents and high levels of fluoride. People have been found to suffer from arsenic skin lesions due to high concentrations of arsenic in water. Contaminated water tends to spread water-borne diseases, which are typically infectious and are spread directly or through flies and filth. Fecal waste, which is prevalent in places with poor sanitary conditions, causes various intestinal diseases. Disease-producing agents, such as bacteria, virus, parasitic worms and protozoa, travel through water sources and interfuse directly through people handling water and food. Other common water-borne diseases that affect many people in tropical regions include cholera, hepatitis, typhoid and dysentery.
The Water Pollution Guide explains that water pollution often harms humans after long-term exposure. Heavy metals are toxic to marine animals that consume them and subsequently to people who eat these animals. Some of them are carcinogenic, and some can cause birth defects. Industrial waste is also harmful to humans and causes acute poisoning, reproductive failure or immune suppression.Learn more about Pollution

The effects of ocean pollution include an interruption in the reproductive cycle of animals; injury, illness and death in marine life; disruption of photosynthesis and illnesses in humans. The ocean's adaptation methods, such as its mechanism to absorb carbon dioxide from the atmosphere, are insufficient to meet the present demands.Full Answer >
Air pollution can cause a variety of illnesses in humans, including asthma, lung cancer, heart disease and even reproductive and developmental disorders. It can also compromise the immune system by overworking the respiratory system and the body's natural defenses. Air pollution also contributes to global warming, increasing worldwide temperatures, raising sea levels and damaging agricultural yields.Full Answer >
Noise pollution has many adverse affects on humans, including stress-related illnesses, hearing loss, sleep disruption, speech interference and loss of productivity, according to eSchoolToday. Perhaps the most acute problem associated with noise pollution is the hearing loss it can cause after long-term exposure. Affecting the eardrums, noise pollution can cause permanent damage when present for a prolonged period of time.Full Answer >
