The basic objective of this study was to compile the available information on the composition of sewage and industrial wastewaters in India and their effect on soil–plant health upon their use in agricultural fields. The composition of sewage water is quite variable depending upon the contributing source, mode of collection, and treatment provided. The composition of sewage water varied from site to site which was in accordance with the type of industries present in that area. Continuous use of sewage and industrial wastewater irrigation recorded improvement in water retention, hydraulic conductivity, organic C and build-up of available N, P, K, micronutrient status, and soil microbial count. The electrical conductivity although increased due to sewage irrigation, it was within the tolerance limit to cause any soil salinity hazard. The toxic metals like Cd, Cr, Pb, and Ni were found to be accumulated in soil and plant due to long-term use of sewage and industrial wastewater irrigation. The concentration of these metals was higher in leafy vegetables than in grain crops. This warrants the potential hazard to soil–plant health suggesting necessity of their safe use after pretreatment as a cheap potential alternative source of plant nutrients in agriculture. 相似文献

The frequent use of phosphorus (P) fertilisers accompanied by nitrogen and potassium sources may lead to a serious long-term environmental issue because of the presence of potentially hazardous trace metals (TM) in P fertilisers and unknown effects on the TM chemical fractions in agricultural soils. A 16-month-long column experiment was conducted to investigate the mobility and chemical forms of Cd, Cu, Cr, Ni, and Zn introduced into a Mollisol and an Andisol through surface incorporation (0–2 cm) of triple superphosphate (TSP) fertiliser. The effects of urea and potassium chloride (KCl) applications were investigated as well. After 15 cycles of 300-mm irrigation, TSP addition increased the 4 M HNO3 extractable TM concentration in the upper (0–5 cm) section of soils. Beyond this depth, metals showed no significant mobility, with minimal leaching losses (<?1.9%, 25-cm depth). The TM chemical forms in the 0–5 cm section were significantly (p?<?0.01) affected by the soil type and fertilisers addition. Cadmium, Ni, and Zn were the elements which appeared in a larger proportion (up to 30%) in the most labile fraction (KNO3 extractable) in fertilised soils. The impact of urea depended on the nitrification-related changes in soil pH, while fertilisation with KCl tended to increase the KNO3 fraction of most metals probably due to K+ exchange reactions. Chromium remained minimally affected by the urea and KCl applications since this contaminant is strongly bound to the less labile solid phases. The low mobility of TM was governed mainly by their interaction with the solid phases rather than by their speciation at soil pH. The mass balance showed that the geochemical processes underwent in time by the P fertiliser increased the amount of TM extracted by the chemical fractionation scheme, therefore the reaction period of TSP with soil particles should be taken into account for evaluating TM availability. Long-term soil fertilisation could inadvertently contribute to an increased concentration and availability of these P fertilisers-born contaminants in the cultivated layer of acidic soils. 相似文献
