“…Regarding the overall pollution, the PLI was1.6 and hence, the soils maybe considered unpolluted to moderately polluted. These results agree with those of Liu et al(2005), Sun et al(2013), Hu et al(2014who reported that sewage irrigation caused pollution of soils with heavy metals. The mean values of CF as shown in Fig.…”

Sewage irrigation may provide an alternative resource due to scarcity of fresh water in Egypt, thus such a practice should be evaluated. A number of 36 pairs of soil samples were collected; each pair consisted of one sample irrigated with fresh water and another irrigated with sewage water from two different sites in Al-Qalyubia Governorate, Egypt. Sewage water-irrigated soils showed higher pH, EC, N, P, K, Fe Mn, Zn, Cd, Pb and Ni than fresh water-irrigated soils. Positive changes in soil properties occurred with sewage irrigation. Bulk density decreased field capacity, organic carbon and nutrients increased by sewage water irrigation. There was build-upin Cd, Pb, Ni and Zn. Single pollution index (SPI) and pollution load index (PLI) indicated no pollution in fresh water irrigated soils as both parameters did not exceed 1.0. Sewage irrigated soils were moderately polluted. The contamination factor (CF) revealed aconsidered contamination with Pb and high for Cd, Ni and Zn. The contamination degree was very high. Food crops cultivation in such soils should be practiced under precautions with a change in the cropping pattern.

Low-impact development (LID) facilities can not only effectively control rainwater runoff and its pollution, but also enhance the value of urban water resources in water systems. Current studies usually pay more attention to the effect of pollution control indicators, and there are few reports on the evaluation of LID facilities from the perspective of enhancing the value of water resources. Taking the Maluan Bay area of Haicang, Xiamen as an example, an evaluation model of water resource value was established based on the SWMM software and the pollution loss model. From the perspective of economic quantification, the value of water resources brought by three types of LID facilities, such as green roofs, permeable pavement and infiltration gallery, under rainfall conditions in different recurrence intervals was simulated and calculated. In the single rainfall event of 1–10a recurrence interval, the water resource value brought by the green roofs is 679.14–787.49 RMB/hm2, the permeable pavement is 79.07–383.37 RMB/hm2 and the infiltration gallery is 825.45–1,021.79 RMB/hm2. The results show that the value of water resources brought by the three types of LID facilities decreases with the increase of rainfall recurrence interval.

“…Tailings are an important mining waste and act as a source of contaminants, which poses a serious risk to human health and have ecological implications [3] . Tailings deposit not only destroys surround ecological environment, but also poses a threat to water, soil, plants, animal and human beings by leaching [4][5][6][7][8][9][10] . Under the effects of temperature and precipitant, tailings released different hazards by the variation of forms and migration [11] .…”

The leaching of heavy metals from tailings deposit due to the oxidation of sulphidic tailings and formation of acidic leachate is considered a high risk to the surrounding environment. Temperature plays an important role in the leaching of heavy metals from tailings in changing acid-based environment, especially in the Arctic area. To investigate how the temperature variation affected metal release from tailings in the Arctic area, a series of column leaching experiments was conducted under four temperature situations (5°C, 10°C, 14°C and 18°C). Physicochemical properties, Fe, Zn, Ni and Mn concentrations of leachates at each cycle were measured, and multivariate statistical analysis was applied to research the effect of temperature on heavy metals leaching from tailings in the Arctic area. The results showed that higher temperatures encouraged tailings to oxidation and sulfuration of and promoted heavy metal release from the tailings through precipitation and erosion. Ni, Zn and Mn have similar releasing resources from tailings and positive correlation in the leaching activity. Rising temperature accelerated Fe leaching; Fe leaching promoted leaching of the other metals, especially of Mn. Appropriately increase temperature will accelerate oxidization and sulfidization of the tailings, promote acid generation and increase TDS and, finally, promote the release of heavy metals. Climate change, with rising temperatures increasing the risk of heavy metals leaching from the tailings, should be given greater attention. Keeping tailings away from the appropriate temperature and in a higher alkalinity is a good method to control the leaching of heavy metals from tailings.
