The hazards of water pollution: Practically all water contaminations are dangerous to people and in addition lesser species; sodium is embroiled in cardiovascular sickness, nitrates in blood issue. Mercury and lead can cause anxious scatters. A few contaminants are cancer-causing agents. DDT is harmful to people and can change chromosomes. PCBs cause liver and nerve harm skin emissions, regurgitating, fever, Diarrhoea, and foetal anomalies.
Marine pollution is one of the worst things that has happened to our planet. It occurs when harmful, waste is dumped into our streams, rivers, lakes, and oceans. Pollution comes in many different ways, everything from chemicals, to plastic, agricultural, and residential waste. Most marine pollution comes from land. Air pollution also plays a huge factor by carrying off pesticides into our oceans.
Even though they are treated, they are never the same fresh water. In many situations, the sewage is not treated but directly dumped into the sea or water bodies. This is very dangerous because they pollute the environment and water bodies and bring many deadly diseases to us. Septic Tanks - Biological processes break down the solids from septic tank and when the liquid is drained to the water it is making huge troubles. The e-coli bacteria which is present in human waste is very dangerous and drinking this water can cause harmful side effects .
SCOPE AND RATIONALE : In this research, I would be analyzing the reason for increase in water pollution both global and locally. How this pollution affects our life; why people don’t care about preserving this precious Natural resource and what are we doing/treating it now. I personally, want to know how an individual can do to protect our planet against all this pollution. INTRODUCTION: Water is life, with almost 70% of the earth’s cover being water; it undeniably becomes one of our greatest resources. But the heart-rending news is that today, it’s Infested with waste ranging from floating plastic bags to chemical waste, our water bodies have turned into a pool of poison.
Wastewater is often classified as industrial or domestic wastewater. In waste water, it contains a lot of harmful pollutants liked: lead, manganese, cadmium, zinc and so on. As known, these pollutants are very dangerous when humans or other species consumed or even when exposed to it. These will affect human health and kill aquatic organisms. Many serious health effects including mutations, cancer, organ damage and death are caused by violet dye in large quantities.
The problem of soil pollution arises due to mixing of toxic, and polluted materials in the soil. Illegal dumping is the biggest reason for soil pollution, which adversely affects the quality of soil and the health of people living on it. Soil pollution also spreads through polluted water absorbed by the soil. Chemical compost used in agricultural work also badly pollutes the soil. Litter and dirt also pollute the soil.
Water pollution is the contamination of water due to unhealthy human activities. The pollution is mostly caused by industrial waste, global warming, garbage and waste dumping, and oil leakage. According to waterbenefitshealth there are many types of water pollution such as “Surface water pollution, Groundwater pollution, Microbial pollution, Oxygen Depletion pollution, Nutrient pollution, Suspended Matter pollution, and Chemical pollution.” Water pollution is a hazardous case in the world as it leads to hunger, poverty, diseases, extinction of aquatic animals, and lack of human access to fresh water.
One of the most critical problems of developing countries like Bangladesh is improper management of vast amount of wastes generated by various anthropogenic activities. The unsafe disposal of these wastes into the ambient environment is contributing to the increasing level of pollution in those area. Water bodies especially freshwater reservoirs are the most affected components of the ecosystem due to this pollution loads. This has often rendered these natural
Water pollution refers to the changes in the physical, biological, chemical or thermal conditions of water body which harmfully disrupts the balance of ecosystem. Water pollution results when overwhelming amount of waste coming from different sources of pollutants such as effluent, litter, refuse sewage or contaminated runoff could no longer be accommodated by the natural ecosystem (WRC, 2000). The main sources of water pollution are agricultural activities, commercial and industrial discharges, domestic and municipal wastewater (Rashid, 2012). First of all, the agricultural intensification has been the origin of several harmful effects on the environment even if it allows covering the food needs of the population. The use of fertilizers and pesticides is considered to be the potential source of water pollution (FAO, 1978).
SURFACE WATER POLLUTION: FACTORS AND IMPLICATIONS Surface water includes water bodies on the earth 's crust such as well, river, lake, pond, stream, ocean. The water we use for our daily purposes and supplied by the municipalities mostly includes surface water primarily from river catchments. Water for agriculture is taken from rivers; it used to be taken from wells also but now it has shifted to bore wells mostly. Pollution refers to the presence of foreign matter in the resource which degrades the quality of the resource and may cause harm to the consumers. Surface water pollution occurs in many ways.
