Chloride concentrations are increasing at a rate that threatens the availability of fresh water in the northeastern United States. Increases in roadways and deicer use are now salinizing fresh waters, degrading habitat for aquatic organisms, and impacting large supplies of drinking water for humans throughout the region. We observed chloride concentrations of up to 25% of the concentration of s...

This inequality is especially critical for Asia, which has 60% of the world’s population but only 36% of the world’s water. Water quality in terms of pollutant loading also is not distributed equally and is related to the type of use and a country’s level of development (Figure 2). Developing countries often have less capacity to improve water quality and depend on lower-quality water for a var...

using of saline water for irrigation of crops is known as a strategy of on-farm irrigation water management. in this study, the cyclic using of saline and fresh water and its effect on soil salinity were investigated. field experiments were carried out in randomized complete block design under drip irrigation for maize crop with 9 treatments. the treatments were based on alternative irrigation ...

Dünya çapında ekonomik ve çevresel maliyetine rağmen şişelenmiş sulara olan ilgi artmaktadır. Şişelenmiş erişim gücü az kesimler ise şehirlerde bulunan tatlı su çeşmelerinden içme suyu ihtiyaçlarını karşılamaya çalışmaktadırlar. Bu çalışmada Konya’da satılan sulardan 24 adet doğal kaynak suyu, 4 mineralli 28 alınan numunelerde başlıca dezenfeksiyon yan ürünlerinden trihalometan (THM) (kloroform...

abstractthe purpose of this study was to compare the heavy metal uptake of cd in liver tissue of endemic fish aphanius sophiae in the saltwater eshtehard of karaj and fresh water in laboratory conditions, the relationship between cadmium accumulation in the liver, the effect of salinity and different concentrations of cd uptake. sampling did randomly from salt river in the spring and summer 201...

The relevance of deionized water as a control treatment in vase life experiments and the effects of major tap water components on cut flower water balance were investigated. Chrysanthemum (Dendranthema x grandiflorum Tzvelev cv. Cassa) was used in all experiments. Deionized water gave a sharp decrease in fresh weight of the cut flowers after 1–3 days. This decrease was absent in tap water. Afte...

Recent studies of the fluxes of sodium and chloride across euryhaline teleost fish have shown that acclimation to fresh water involves a sharp reduction in the flux of both ions (Evans, 1967 c, 1969; Motais, 1967; Maetz et al. 1967 a, b; Potts & Evans, 1967; Ports et al. 1967). It has been shown, at least in Fundulus heteroclitus (Potts & Evans, 1967), Tilapia mossambica (Potts et al. 1967), Xi...

Cantaloupes are associated with recent outbreaks of foodborne illnesses and recalls. Therefore, new approaches are needed for sanitization of whole and cut fruit. In the present study, whole cantaloupes were submerged into water in the following 3 conditions: 10 degrees C water for 20 min (control), 20 ppm chlorine at 10 degrees C for 20 min, and 76 degrees C water for 3 min. Populations of mic...
