监测结果表明,钵池山水体中总氮、总磷、叶绿素a含量较高,富营养化严重,藻类大量繁殖。建议采用控源截污、清除淤泥、调水搞活等处理措施,对钵池山公园水质富营养化进行治理。 相似文献

连续监测和分析了下三台水库的水质,对水污染程度进行了评价,水库高锰酸盐指数、总氮和总磷超标严重,呈现富营养化状态,总体水质为Ⅴ类和超Ⅴ类,已无法满足集中式生活饮用水水源地的水质要求。针对水库污染严重的现状,提出了控制污染源、削减污染物的综合治理措施。 相似文献

水中的总磷及其自动在线监测仪的研制 总被引:1,自引:0,他引:1
论述了总磷在水环境中的存在形式、来源以及导致水体富营养化时总磷的浓度水平.为了研制出满足国内使用的总磷自动在线监测仪,调研了几种水中总磷的测定方法,通过优化筛选,确定水中总磷测定方法为紫外催化-过硫酸钾氧化-钼酸铵分光光度法,该方法既具备了国标分析方法的氧化体系,又通过紫外线照射,保证了该体系总磷的氧化率.在大量试验基础上证明该仪器完全符合《总磷水质自动分析仪技术要求》(HJ/T103-2003)的要求,可以满足水体中总磷自动在线监测的需要. 相似文献

The oil palm is an economic crop that has gained worldwide recognition due to its importance. Produce such as the stem, fruits, and leaves contain phytonutrients and antioxidants that are mediators of cellular functions and a cure for various ailments. The oil palm plantations receive inputs of elements from natural and anthropogenic sources. However, while some of the elements are beneficial, they may be toxic at high concentrations. The quality of ground water is important due to the possible uptake of trace and major elements by the oil palm. In this study, the concentrations of fifteen elements in ground water from oil palm plantations in southern Nigeria were measured. The inductively coupled plasma optical emission spectrometer (ICP-OES) was the instrument of choice because of its multielemental capabilities. The study revealed that of the trace elements, the highest concentrations were obtained for lead (Pb) (0.090–10.29 mg/L), while the lowest concentrations were obtained for cadmium (Cd) (0.119–0.391 mg/L). The concentration of the metals were compared with water quality standards established by the World Health Organization in 2011. 相似文献

Secretory proteins (casein micelles) were air dried prior to elemental analysis either without treatment, following glutaraldehyde fixation and dialysis, or following dialysis against distilled water. Samples were then examined by energy dispersive X-ray microanalysis in a scanning transmission electron microscope (STEM). Untreated samples and samples dialysed against distilled water retain colloidal (bound) elements as compared to glutaraldehyde treated samples. Contamination of air dried casein micelles by ionic constituents in the non-protein aqueous phase was observed in the untreated sample and in the glutaraldehyde treated sample. Dialysis of casein micelles against distilled water reduced contamination from the aqueous phase without diminishing the apparent concentrations of colloidal elements. 相似文献
