Some of the main species of fish in Lake Ontario are walleye, trout and salmon. The Lake Ontario food web has been damaged by over-fishing, fluctuation in nutrient levels, industrial chemicals, agricultural fertilizers, untreated sewage, phosphates from laundry detergents, and pesticides. Some pollutant chemicals that have been found in the lake include DDT, benzopyrene, PCBs, chromium, lead, mercury, and carbon tetrachloride. Conclusion Future research into Lake Ontario’s aquatic health could be to study how the pollution has changed the ways we treat the water from the lake before human consumption. Over the years the water treatment methods have changed to adapt to poorer water conditions and by tracking these changes we may be able to further understand the negative impact that we are placing on the fresh water
One of the major risks in using recycled water is enteric illness. Recycled water has microbial pathogens which could cause an effect to human health. Some categories of the microbial pathogens are viruses, bacteria, helminthes, and protozoa. These pathogens could cause sickness to human health like hepatitis, amoebas, diarrhea, and many more. There are main problems arise in long-term contact with recycled water especially in rural and urban communities, recreational areas, occupational sites, schools, subdivisions, and in illegal contacts with the recycled water
Water pollution is a very prevalent problem throughout the world. It affects ecosystems, deters the natural food chain, and can cause disease in both animals and humans. But is water pollution affecting natural lakes and ponds in local areas? In this experiment, Daphnia magna will be used in a bioassay to find if water from local areas is habitable for aquatic organisms. Daphnia magna are small freshwater invertebrate organisms.
Eutrophication is an extreme wealth of supplements in a lake or different waterways. Eutrophication happens when the spillover of residue from and land go into a waterway. At the point when this happens, a thick development of vegetation happens, which exhausts the huge oxygen request (BOD), which means the oxygen that is accessible to amphibian life is no more. Eutrophication might likewise be realized by the seepage of sewage, mechanical squanders, or cleansers into a waterway. As the stuffed plants cease to exist, the dead and rotting vegetation exhausts the lake 's oxygen supply.
A clean water is very essential not just with the environment but most especially among humans. It is important for us to know if the water we drink is clean and safe to drink because we are pertaining to our health. If we drink contaminated water, we are drinking the risk of having bacteria and viruses into our body so it is essential for us to know how safe the water we are drinking is. It has always important for us to sustain our drink and also among other living organisms in the environment. Most of the water we use comes from lakes, ocean, and rivers but before we use it, it undergoes many processes to remove such chemicals.
Finall a nonpoint source is pollution that is harmful substances that occur from human activity. These oils or other substances get into the lake and make the water cointaminated, this is harmful and can cause sicknesses. 21. Nitrate if you are exposed to nitrate in your drinking water you could condition caused by lack of oxygen in extreme cases it could cause death. It could react with other chemicals causing more sickness.
2.5.2 Chemical control This involves the application of chemicals to the weed so as to eradicate it. This method just like any other has its pros and cons. For instance, the use of chemicals can have potential adverse impacts on man and the environment. Furthermore, the chemicals may as well affect the fish population in the water body. The use of chemical control also poses a challenge especially when it is to be applied on a shared resource e.g.
Addition to these, disposal of dead bodies, discharge of industrial and sewage wastes and agricultural runoff, which are major cause of ecological damage and pose serious health hazards (Meitei et al., 2004a). The pollutant from agricultural lands such as fertilizers, pesticides and fungicides and from anthropogenic activities such as mining, disposal of toxic metals, human and animal faeces, industrial, domestic, municipal wastes are continuously discharged into river, such as Vaigai, are the major casues for deterioration of water quality (Karet al,2008 and Amman et al, 2002). In order to maintain the quality of drinking water, an essential component to humans and other living
Unfortunately our oceans are suffering from many types of pollutants that are prominent in our environment. One of the main distributors of pollution is sewage. Sewage and other polluting substances flow into the world's rivers and drainage pipes until all of the substances dump out into the ocean. In addition to sewage, other chemicals finds its way to the oceans, which leads to the reduction of oxygen being released into the atmosphere. With this in place, the waters become murky and filled with substances that can harm marine life.
Water pollution is contamination of bodies of water, suspended in the water or depositing. For example, lakes, rivers, and oceans. These toxic substances are harmful for the aquatic ecosystem but these pollutants can find its way into the ground water, which can contaminated water we use every day. There are different kinds of pollutants such as organic, inorganic radioactive etc. First of all, what is clean water?
