“…Anthropogenic contamination of waterways constitutes a major problem in both developing and developed countries around the world (Barrett et al 1998;Gelberg et al 1999;Tilman et al 2002;Grande et al 2003;Fytianos and Christophoridis 2004;Camargo and Alonso 2006;Chen et al 2006;Nas and Berktay 2006;Chang 2008;Ma et al 2009). Declining surface water quality directly affects human and ecosystem health, which further impacts economic development and social wellbeing.…”

Water quality has degraded dramatically in Wen-Rui Tang River watershed, Zhejiang, China, especially due to rapid economic development since 1995. This paper aims to assess spatial and temporal variations of the main pollutants (NH + 4 -N, TN, BOD 5 , COD Mn , DO) of water quality in Wen-Rui Tang River watershed, using the geographic information system, cluster analysis (CA) and principal component analysis (PCA). Results showed that concentrations of BOD 5 , COD Mn , NH + 4 -N, and TN were significantly higher in tertiary rivers than in primary and secondary rivers. From April 2006 to March 2007, the concentrations of NH + 4 -N (2.25-57.9 mg/L) and TN (3.78-70.4 mg/L) in all samples exceeded Type V national water quality standards (≥2 mg/L), while 5.3% of all COD Mn (1.83-27.5 mg/L) and 4 -N and TN in tertiary rivers had a significant negative correlation with 5-day cumulative rainfall and monthly rainfall, while there were no significant correlations in primary and secondary rivers. The results of CA and spatial analysis showed that the northern part of WenRui Tang River watershed was the most seriously polluted. This region is characterized by the high population density and industrial and commercial activities. The PCA and spatial analysis indicated that the degraded water quality is caused by anthropogenic activities and poor wastewater management.

“…As a result of the mentioned study, nitrate levels in 15.7% of investigated wells had exceeded the critical limit of 10 mg/L [30]. In another study that investigated nitrate in Ontario, Canada, 14% of farmstead domestic wells contained nitrate above the 10 mg/L limit [31].…”

This study was carried out to determine the drinking water quality of İpsala District, known as "Rice Land" in Turkey. Water samples were collected from 23 stations, including all the residential areas in winter 2013. Some physical, chemical, and microbiological water quality parameters (temperature, dissolved oxygen, pH, conductivity, turbidity, nitrite, nitrate, ammonium, sulfate, phosphate, chloride, fluoride, and biological oxygen demand) were determined and some multi-statistical methods were applied to detected data. The geographic information system was also used in order to make a visual explanation by presenting distribution maps of investigated parameters, and groundwater samples were assessed according to national and international quality criteria. According to data observed, although the investigated parameter levels in ground water of İpsala District did not exceed the limit values for drinking, the region has class II-III (Turkish Regulations) groundwater quality in terms of nitrite and nitrate parameters in general.

“…There are no known studies about the relation between DSW administration to mice and the animals' MCV levels. In humans, and specifically infants, a relation between nitrate-nitrogen and nitrite-nitrogen intake was reported, as was the development of methemoglobinemia in infants (10)(11)(12)(13). DSW contains higher concentrations of these salts than either SSW or purified water.…”

Objectives: To clarify the characteristics of deep-sea water (DSW), we investigated the hematological, immunological and biochemical effects of DSW, specifically the so-called Japan Sea Proper Water (JSPW), samples of which we collected from the Japan Sea at a depth of about 300 meters.Methods: Five groups of five mice each were orally administered, ad libitum for 12 weeks, one of the following: 1.2% DSW, 12% DSW, 1.2% surface-sea water (SSW), 12% SSW, or purified water (control).Results: Among these groups, no significant differences were observed in the average reduction of water intake, food consumption or body weight. The mean corpuscular volume, however, was significantly lower (p<0.05) in the 1.2% DSW group than in the control group. Moreover, serum immunoglobulin G and A values were significantly higher (p<0.05) in the 12% DSW and the 12% SSW groups, respectively, compared with the control group. In addition, the serum glucose value in the 12% DSW group was significantly higher (p<0.05) than in the control group.Conclusions: The findings of the present study suggested the presence of some toxic components in DSW. Before a final answer is reached about whether DSW, and specifically JSPW, is bad for human health, the pathophysiology of findings such as the decreased mean corpuscular volume, the higher immunoglobulin G value and the higher glucose value should be investigated.
