The aim of this study was to determine natural radioactive and heavy element concentrations in Mersin drinking water samples before the commissioning of the Akkuyu nuclear power plant and to collect data for possible environmental contaminations in the future. Drinking water samples were taken from the provincial center, districts, and populated villages. The annual effective dose of natural radionuclides and cancer risks were calculated for each person living in the city. Hazard index and cancer risk were calculated, which were caused by heavy elements.

The interest in study of waste management is being increased worldwide presently as the pollution by various means are made day by day. The waste utilization plays a vital role to overcome these pollutions and make possible to utilize the waste. Bananas plant has no use after harvesting the fruit, but it is used in following context significantly: viz. producing bioethanol, single cell protein, cellulase, citric acid, lactic acid, amylase, cosmetics, fibre, bio-film, paper, bio-plastic bio-electricity in the agro-industry, pharmaceuticals, bio-medical and bio-engineering aspect etc.

Entero-parasites protozoan of the genera Cryptosporidium and Giardia have emerged over the past decades as major waterborne pathogens with an increasing number of outbreaks reaching over one hundred and sixty. In line with the national goals of providing safe drinking water supplies, this research was designed. We aimed to estimate the prevalence of Cryptosporidium parvum and Giardia intestinalis infections in surface water plants from ShebinAl-Kom and Tala, Menoufia Governorate and to evaluate routine water purification methods used for parasitic elimination.

The purpose of this study was to modify the sludge from DWTP as a low-cost adsorbent for adsorption of phosphate in wastewater. The absorption performance of MS was examined, and the removal mechanisms were elucidated. The finding of this study is helpful for further development of a low-cost adsorbent based on sludge from DWTP to remove P in wastewater and offers a solution reduce water treatment sludge production and disposal fees also.

The use of a wide range of chemicals to destroy pests and weeds is an important aspect of agricultural practice in both developed and developing countries. This has increased crop yield and reduced postharvest losses. However, the expanded use of such pesticides expectedly results in residues in foods, which has led to widespread concern over the potential adverse effects of these chemicals on human health.

Water-borne diseases have been estimated to cause more than two million deaths and four billion cases of diarrhea annually. Water-borne pathogenic organisms include bacteria, protozoa, and viruses. Heavy metal contamination of water is also a potential threat to human health. This study aimed to detect contamination of potable water with protozoal and bacterial pathogens as well as heavy metals in Gharbiya governorate in the middle of the Nile Delta, Egypt. Therefore, this study was conducted on water samples from 3 different localities in Gharbiya governorate throughout the year 2014.

The present study is concerned with the flora of the Kalabak Basin, an area lying to the south-west of the city of Eskişehir that supplies Eskişehir with drinking water. As a result of our evaluation of the plant specimens collected over 3 years (2001 to 2003), 71 families, as well as 575 taxa belonging to 307 genera, were determined to occur in the study area (569 species, 3 subspecies, and 3 varieties).

Take, for example, a project with the purpose of improving peoples health through increased food production obtained via activities such as irrigation and use of pesticides. Such a project will not be sustainable if water is extracted at a faster rate than it is replenished. Furthermore, if the increased food production is made at the expense of pesticide residues in the drinking water, then the project purpose may be undermined by health problems among the villagers.

A heightened concern for the environment, combined with increasing sophistication in tracking and modelling air currents, has led to the realization that local air and water may be contaminated by pollutants emitted many miles away. Indeed, this realization has resulted in inter-regional and international tensions regarding air pollution. For example, much of the acid rain problem in the northeastern United States is a result of SOx emissions from coal-fired power plants in the Midwest.

To tackle polluted source water, water utilities in the region are often forced to install expensive treatment plants that can cost millions to install and operate. USDA economists estimate that removing nitrate alone from drinking water costs more than $4.8 billion a year. The cost of dealing with algal blooms is particularly daunting. The total capital cost of water treatment that would address cyanobacterial blooms and cyanotoxins, can range between $12 million and $56 million for a town of 100,000 people.

The chemical properties of organics of health concern – hydrophobic and not water soluble - results in a low bioavailability to plants. Plant growth is dependent on the water solubility of nutrients and minerals and water is the transporting vector. Organics with a low water solubility will therefore not be taken up by plants. The presence of organic environmental pollutants, like dioxins and PCBs in agricultural crops is more the result of atmospheric deposition than direct absorption from contaminated soil.

Analysis was conducted on nutrients or nutrient groups for which numeric data were provided in at least 10 of the 137 crop studies identified by the review. In analysis including all studies (independent of quality), no evidence of a difference in content was detected between organically and conventionally produced crops for the following nutrients and other substances: vitamin C, calcium, phosphorus, potassium, total soluble solids, titratable acidity, copper, iron, nitrates, manganese, ash, specific proteins, sodium, plant non-digestible carbohydrates, β-carotene and sulphur.

The cultivation of tea in China and Japan is another of the great industries of these nations, taking rank with that of sericulture, if not above it, in the important part it plays in the welfare of the people. There is little reason to doubt that the industry has its foundation in the need of something to render boiled water palatable for drinking purposes. The drinking of boiled water has been universally adopted in these countries as an individually available, thoroughly efficient and safe guard against that class of deadly disease germs which it has been almost impossible to...

Previous World Health Organization studies have examined the aggregate disease burden attributed to key environmental risks globally and regionally, quantifying the amount of death and disease caused by factors such as unsafe drinking-water and sanitation, and indoor and outdoor air pollution. Building from that experience, this present study examines how specific diseases and injuries are impacted by environmental risks, and which regions and populations are most vulnerable to environmentally-mediated diseases and injuries.

The industrial discharge carries various types of contaminants to the river, lake and groundwater. The quality of freshwater is very important as it is highly consumed by human for drinking, bathing, irrigation and etc. The presence of contaminants from industrial contaminant within the water may reduce the yield of crops and the growth of plant and it will harmful to the aquatic living organism too.
