The pollution of water bodies by an excess of nutrients (N and P) is a worldwide problem with effects on the human health, ecosystems status, climate change, etc. To face with this important issue different regulations were promulgated by the countries, sometimes based on the results from international conventions and programmes. In this chapter, a review of the laws and regulations that affect the discharge of nitrogen and phosphorus is addressed, focused in the case of Europe and the United States. Finally, a brief explanation about international initiatives was performed to understand the global framework concerning nutrients pollution.

In this paper, the results of an investigation of the diversity in microflora species in water bodies of Rostov-on-Don are presented. Susceptibility/resistance of isolated strains to antibacterial drugs (ABD) was studied. A portion of nonfermenting microorganisms (NFMs) constituted of 42.9 %, Enterobacteriaceae family - 28.2 %, Aeromonadaceae family - 23.7 %. In NFM group the sensitivity to all ABD was exhibited by 37.5 % of strains, 43.4 % of strains showed resistance to one antibiotic and 6.3 % were polyresistant (resistance to 3 and more antibiotics). No susceptible strains were detected among Enterobacteriaceae. The resistance to 3 or more ABD for Enterobacteriaceae accounted for 80 %, for Aeromonas - 72 %. In all groups of tested microorganisms, results of the investigation showed a high proportion of strains susceptible to ciprofloxacin, doxycycline, ceftriaxone, levomycetin, gentamicin, imipenem, meropenem, cefoperazone, cefepime. Among Enterobacteriaceae and Aeromonas strains isolates carrying the markers of resistance to ampicillin, nalidixic acid, furagin, co-trimoxazole were found frequently. The performed research of microbial communities in water bodies of Rostov-on-Don made it possible to identify dominant groups of microorganisms in the investigated objects, to reveal pathogenic and opportunistic bacteria, evaluate their antimicrobial resistance with the aim to determine a degree of their potential danger to human health

Surface Water Bodies

Polluted water from many water‐supply stations of the Ukraine gets into surface water bodies, trenches and ponds. Such water contains chlororganic compounds and coagulants that fail to biodegrade and get into the human body within the nutrition chain and are harmful for human health. The results of the carried out research have been applied in designing new water‐supply stations which use sludge degreasing and in reducing the amounts of pollutants emitted into surface water bodies.

The Impact

Colour is the most important part to make any fabric attractive, but its use for dying has become a major environmental hazard. Colloidal particles present with color increases the turbidity, gives bad appearance, foul odour, and obstructs the penetration of sunlight into water bodies required for the photosynthesis process, which interferes with the oxygen flow mechanism and hence marine life. So, it is essential to remove such pollutants from the waste water before its final disposal into water bodies. Photocatalysis is one of the advance oxidation processes, mainly carried out in the presence of light and suitable photocatalytic materials for the degradation of dyes. This chapter outlines the background of dye chemistry, the application areas, and the impact of dyeing effluents in the environment and on living beings.

Negative Impacts

<p>Water pollution from agricultural activities has direct negative impacts on human health, as the well-known blue-baby syndrome —a potentially fatal illness —deriving from nitrate intake in infants. Inefficient farming practices, farming systems discharge large quantities of agrochemicals, organic matter, drug residues, sediments, and saline drainage into water bodies results in pollution poses demonstrated risks to aquatic ecosystem, human health and productive activities including agriculture. In order to design effective remediation strategies there is a need to target sources of excess nutrients, and sediments in an efficient way. Standard operating procedures (SOP) that provides step-by step instructions on how to collect, prepare and prepare soil samples from agriculture watersheds for multi-isotope analysis were evaluated and standardized in agricultural catchments in Asia (Australia, China, India, Sri Lanka, Vietnam), Europe (Austria, France, Germany, Ireland, Romania, Slovenia, Switzerland, United Kingdom) and Africa (Morocco and Ghana) in a coordinated research project managed by the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture. The δ<sup>18</sup>O, δ<sup>2</sup>H, δ<sup>15</sup>N-NO<sub>3</sub>, δ<sup>18</sup>O-NO<sub>3</sub> stable isotope values in water samples were used to apportion the contributions of the different sources (chemical fertilizers, organic fertilizers from livestock, and rural domestic sewerage). The compound specific isotope analysis (CSIA)-based monitoring approach (δ<sup>13</sup>C and δ<sup>15</sup>N) was used to evaluate in-situ degradation, transport, transformation and fate of pesticides. Information gained will fill knowledge gaps for catchment scale predictive models and provide guidelines and decision trees to develop an isotopic analytical toolbox that could be adapted to different agricultural management situations.</p>

High Iron Content

This study assessed the concentrations of metals in the Dourados and Brilhante Rivers, investigated the influence of landscape features surrounding these rivers on water quality, and evaluated the risks associated with metal contamination for aquatic biota and human health. Sampling was conducted at eighteen sites distributed along the rivers in June 2016. The concentrations of metals (Cu, Zn, Mn, Fe, Cr, Al and Co) in the water were analyzed by inductively coupled plasma optical emission spectroscopy. All the samples possessed Fe concentrations above the threshold value for aquatic biota (0.3 mg L-1). Moreover, land use and land cover assessment of the study area revealed extensive agriculture activity, particularly in areas surrounding the Dourados River headwaters. Fe bioavailability for both rivers indicated risks for aquatic biota and human health. Overall, the elevated Fe content in these rivers was attributed to anthropogenic activity in the vicinity of these water bodies and the soil characteristics of the area. Considering the importance of river basins, it is necessary to implement public policies for their conservation, especially those related to the cultivation of forests of native species and sustainable agricultural practices, in addition to improving the effluent treatment infrastructure, which is essential to minimize the adverse effects of contamination by chemical elements in water bodies. Keywords: aquatic ecosystems, environmental contaminants, forest fragments.

Heavy metals being persistent pose conglomerated hazards towards safety and human health. Impacts of heavy metal pollution can be exhibited by both natural and anthropogenic activities. Therefore, developing nations are under immense pressure of controlling the environmental impacts of increasing industrialization and pollution, subject to their limited resources and infrastructure. Bioindicators are important biological entities to determine the positive/ negative changes in the desired ecosystem. They are the fast respondents towards the slightest changes and provide early reliable results. Identifying & establishing a suitable bioindicator can provide a faster and inexpensive way to address the undesirable effects. Cyprinus carpio, a freshwater fish, is used to determine the Lead (Pb) at different locations of Yamuna River and the bioavailability in different tissues. In the present study, we are trying to establish fish as an indicator of lead pollution in the river. It is a well-known fact that the water bodies are most affected by human activities. Polluted water bodies can lead to adverse effects on human health. Lead is also known to cause phytotoxicities in aquatic and terrestrial plants. This study is therefore an attempt to identify the harmful impacts of lead in River ecology. Ten fish specimens of C. carpio were collected from four different sites of Yamuna River and analyzed for Lead accumulation in fish tissues. High concentration and accumulation were observed in specimens collected from various locations and found to be higher than the permissible limits for human consumption.
