Since algae consume dissolved oxygen in water, this can cause depletion of dissolved oxygen that very crucial to fish and other aquatic creatures to survive. Algal blooms is condition where algae grow progressively and this condition cause decreasing in dissolved oxygen in water and also can affect the health of water system included living organism like fish. Depletion of dissolved oxygen can cause extinction of fish population in that system. Some algae can disrupt human health because of their capabilities of elevated toxins and production of parasites that can disrupt human immune system. Human can be affected if they come in contact with polluted water, eat tainted fish or shellfish, or drink that polluted water.
Result would be and algal bloom. Alga can be very toxic to animals and can deplete water of oxygen suffocating fish. Pollutants will find a way into the wetlands from mines or processing plants, industrial areas and through accidental oil spills. Visitors to rivers and rock holes pollute wetlands by throwing rubbish in the water or swimming in there with lots of sun screen on or insect repellent on. These chemicals will wash off and affect the water as the substances can be harmful and could reduce the water quality.
Acid rain falls not only on the land but also on the lakes, rivers and streams, then make a disaster for the ecosystem for the species that live there. In Sweden acid rain made the lakes so acidic and was the reason behind the death of all the fishes there. The pH concentration will change if the lakes or the streams became acidic, and this will unfortunately cause problems for the fish species and its eggs also. At pHs that is lower than 5 the fish's egg can't be hatch and this will cause later a decline in the fish population and later it might be eliminated. If acid rain falls it will also affects the plants that some animals depends on as a source of food and this will also be a reason behind death of many animals populations (internet
There are several types of water pollutants; one category is the microbiological, which refers to the contamination of viruses and bacteria in water. Another category is nutrient pollution, which is caused by excessive amount of nutrients in water supplies, making it undrinkable. Chemical water pollution refers to the chemical compounds that end up in water supplies. Many industries contaminate water with toxic or radioactive materials and sometimes use rivers and lakes to dispose of waste heat, resulting in thermal pollution. Water quality is threatened by many sources, besides fecal matter, water is exposed to many toxic substances.
Air pollution causes respiratory problems in people and animals. Pollutants in the air can cause brain damage when exposed in great amounts (Air Pollution). In certain rural countries people wear mask to filter the air because factories emit so much pollution into the air. Many countries don't have proper water filtration systems and the pollution dumped into water is ingested by people and they could get sick and die. When pollution is dumped into water, fish are likely to ingest the pollutant and people eat the fish in countries with little food regulation, this can cause harmful effects to the humans.
What is water pollution and who cause water pollution? Water pollution It's a huge problems in earth, animals are the most effect when water is contaminated, but also water pollution affected humans health. Sometimes we don’t see but we are always contaminating water by throwing thrash and exposing chemicals on water. Humans are the reason why water pollution exist, but we can something about it to end water pollution. What is water pollution?
Many factors cause water pollution to occur and increase over the years. The most important thing uses to cause water pollution is sewage pollution of boundary waters. Sewage mentions to fluid wastes containing a combination of human feces and wastewater from non-industrial human hobbies such as soaking, washing, and cleaning. In countless poor areas of the world, sewage is dumped into innate waterways, in the nonexistence of useful alternatives. Untreated sewage poses a main risk to human condition as it contains waterborne pathogens
One of the major problems that acid rain can cause in a human being is respiratory problems. Many can find it difficult to breathe, especially asthma patients. Asthma, along with dry cough, headaches and throat irritations can be caused by the sulphur dioxide and nitrogen oxide from acid rain. Acid rain can be absorbed by both plants and animals. When humans eat these plants or animals, the toxins inside of their meals can affect them.
Human Health - The contiguity of pipelines to groundwater sources can cause serious contamination that may have a detrimental impact on communities. If dilbit is involved in a spill, the diluent evaporates rapidly in the air and can lead to high airborne levels of toxic components. This adversely affects the health and safety of surrounding societies. 3. Ecological: If ingested by aquatic organisms, oil spills can cause serious harm and death.
In most cases, this mercury is carried by fish living in the contaminated waters. In all, there are more than four hundred industrial plants found along the banks that contribute to this dumping, and therefore contribute to the poisoning of millions of people. Another contamination to the water has been fertilizer runoff, which has lead to an increase in the nutrient levels of water weeds. The spread of fertilizer has also affected the spread of Algal blooms, which have grown to cover rivers, causing for a decrease in the flow of water, making it more difficult for pollutants to be flushed away. In terms of the water, the levels of certain indicators are 40 times higher than recommended by the World Health Organization.
