When phosphate from wastewater is used, the main problem is that there will be microbiological hazards so the plants and animals can be contaminated from that alum-precipitation. One person generates 150L of wastewater, 500 habitants in Rongotea and each 1L; it needs 200mg of
The presence of bacteria and pathogenic organisms is a concern when considering the safety of drinking water. Pathogenic organisms can cause intestinal infections, dysentery, hepatitis, typhoid fever, cholera, and other illnesses. Sources of Bacteria in Drinking Water: The Need for Water Testing Human and animal wastes are a primary source of bacteria in water. These sources of bacterial contamination include runoff from feedlots, pastures, dog runs, and other land areas where animal wastes are deposited. Additional sources include seepage or discharge from septic tanks, sewage treatment facilities, and natural soil/plant bacteria.
Abstract: Cadmium is very toxic metal for living organisms. It has adverse effects on living organisms mostly is disturb the activities for cells, tissues, and metabolic process of living organisms. Its major source is food such as plant based food, meat, cereals, fish, shellfish etc. It has toxic effects on brain, bone, digestive system, cardiovascular system and DNA. It cause severe acute and chronic toxicity.
Other invasive plants are Melaleuca, Old World climbing fern, Australian Pine, Brazilian Pepper, and Seaside Mahoe. Power plants released mercury to the atmosphere and fell to the water as rain. Phosphorus and mercury caused water pollution and negatively affected many animals and the ecosystem. Many panthers were found dead. We have to improve the water quality in the Everglades otherwise more animals are going to die.
Nutrient pollution coming from agricultural runoff and other fertilizers allows for the growth of species that upset the balance of the ecosystem such as Cattail, harmful algae bloom, and duckweed. The sulfur in the agricultural fertilizers leads to accumulation of toxic mercury in fish, birds, and mammals. Also, exotic animals or invasive species displaced native and threatens to disrupt the ecosystem balance. The purpose of this experiment is to determine how the water quality affects the Everglades ecosystem and how water pollution impacts different species. Urbanization is a big threat that contributes to poor water quality in water pollution.
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
Industrial decisions, such as the addition of lead to paints, dyes, and gasoline, have created an epidemic of lead poisonings. Lead is a naturally occurring substance and can be found in organic and inorganic forms. Lead is a reproductive toxicant detrimental to human semen quality. Decreased sperm count, motility, acid phosphatase, succinic dehydrogenase, fructose, surface reaction of sperm head DNA besides increasing abnormal sperms was reported in occupational exposure of lead in printing press workers in India. Higher lead level lowers sperm’s ability to bind and fertilize the egg.
Introduction: Foodborne illnesses are any illness resulting from the food spoilage of contaminated food. Most foodborne disease caused by pathogenic bacteria, viruses, or parasites that contaminate the food. In addition to, other foodborne diseases it may happened due to poisonings caused by harmful toxins or chemicals that have contaminated food. Also, foodborne pathogens it can be acquired throughout contaminated water, from contact with animals or their environment, or through direct transmission person-to-person. In this article we will discuss about one of the most common foodborne pathogens it is campylobacter.
The dust which results for erosion also causes diseases within humans such as tuberculosis and anthrax. Not just the topsoil but the fertilizers and pesticides put into the farmland leads to runoff. This runoff infects lakes and rivers and eventually oceans around them. Once the
Pollution caused by crude oil and its petrochemical based products disrupt and alter the ecosystem balance. Incomplete combustion of crude oil leads to the production of greenhouse gases which causes acid rain and also accelerates climate change which is already having negative effect on the environment. Crude oil pollution poses a huge risk to the ecosystem if not properly managed because it enters the food web through the plant which is later transferred from one food chain to the other food chain (Sathishkumar et al. 2008). The strong persistence nature of crude oil and its total petroleum hydrocarbon (TPH) derivatives in air, water and land has attracted much attention from government and environmental stakeholder because accumulation of this pollution in plants and animal tissues leads to toxic, carcinogenic and mutagenic effects which invariably leads to death (Abd-Elsalam et al.
