“…Soluble reactive phosphorus is related negatively to flow, indicating the importance of point sources in the total losses (Jarvie et al, 1998). This is confirmed by the strong correlation between boron concentration and soluble reactive phosphorus found by Neal et al (1998a) for all the rivers, including the Ouse river, draining into the Humber estuary. Boorman and Shackle (2002) estimated the point source contribution to total losses of phosphorus and nitrogen to be 40 and 7%, respectively.…”

This study assessed the impact of potential climate change on the nutrient loads to surface and sub-surface waters from agricultural areas and was conducted using the Soil and Water Assessment Tool (SWAT) model. The study focused on a 3500 km 2 catchment located in northern England, the Yorkshire Ouse. The SWAT model was calibrated and validated using sets of five years' measurements of nitrate and orthophosphorus concentrations and water flow. To increase the reliability of the hydrological model predictions, an uncertainty analysis was conducted by perturbing input parameters using a Monte-Carlo technique. The SWAT model was then run using a baseline scenario corresponding to an actual measured time series of daily temperature and precipitation, and six climate change scenarios. Because of the increase in temperature, all climate scenarios introduced an increase of actual evapotranspiration. Faster crop growth and an increased nutrient uptake resulted, as did an increase of annual losses of total nitrogen and phosphorus, however, with strong seasonal differences.

“…With no direct measurements of either diffuse or point source contributions during this period, it is impossible to determine the relative contributions and changes in point-source P-loadings before and after Pstripping and therefore assess the impact of P-stripping on in-stream P loads and concentrations and, therefore, a simple pragmatic approach to estimating effluent loads was used in this study. Neal et al (1998a) and Jarvie et al (2002 b,c) have used boron as a conservative tracer of sewage effluent to determine changes in hydrological dilution of point sources and detect changes in effluent P content. However, boron is not routinely measured by the EA, and no such tracer separation can be performed here.…”

Water quality data, collected by the Environment Agency in England and Wales over 10 years (1991 2000) were used to examine the spatial distribution of nutrient pollution risk and for assessing broad-scale spatial and temporal variability in nutrient fluxes across the Wye catchment. Nutrient water quality across the upper and middle Wye catchment, and along the main River Wye, is generally very good. However, the main areas of concern lie in the small tributaries in the south and east of the catchment, which have lower dilution capacity and high agricultural and effluent inputs, and where mean Total Reactive Phosphorus (TRP) in some cases exceed 1mg-P l -1 . Indeed, mass load calculations have demonstrated that the lowland south and east portion of the catchment contributes more than 85% of the whole-catchment TRP and more than 78% of nitrate (NO 3 ) loads. Ratios of NO 3 :Ca concentrations were used to fingerprint different water-types across the catchment, linked to weathering and agricultural activity. The Wye catchment has been subject to two major sets of perturbations during the study period: (i) climatic fluctuations, with a drought during 1995-6, followed by a subsequent drought-break in 1997/8, and extreme high river flows in the autumn/winter of 2000/2001, and (ii) introduction of tertiary P-treatment at major sewage treatment works in the catchment. The implications of these perturbations for the nutrient water quality of the Wye catchment are discussed. Recommendations are made for more targeted monitoring to directly assess diffuse source nutrient contributions.

“…Boron (B) is a ubiquitous chemical element in nature and has a high affinity for oxygen (Neal et al 1998;Wyness et al 2003). So far, over 150 boron minerals have been found all over the world, but only about ten of them have industrial value.…”

“…Skarn boron deposit (distributing in Fengcheng, Kuandian, Yingkou counties of Liaodong peninsula) and continental salt lake boron deposit (distributing in salt lakes of Tibetan Plateau) are the two typical types of boron mines in China (Zhu and Wang 2007). Both natural and anthropogenic factors can lead to the release of boron into air, water, or soil (Neal et al 1998), resulting in boron contamination in ambient environment. Because of the wide application of borate and boric acid in industrial and other related fields, boron may also be discharged into the riverine environment with the drainage and leachate from mining industry (Akar 2007;Wyness et al 2003;Adriano et al 1980).…”

To evaluate boron contamination of public drinking water in China, both dissolved and total boron contents in 98 public drinking water sources from 49 cities, 42 brands of bottled water samples from supermarkets in several cities, and 58 water samples from boron industrial area were measured by inductively coupled plasma-mass spectrometry (ICP-MS). Our experimental results showed that boron existed in public drinking water sources mainly in dissolved status with total
