摘要

Now-a-days public health concern has been linked with the use of industrial and domestic waste water for irrigation on vegetable cultivation.The present study was focused to evaluate the physico-chemical quality of sewage water and shallow water and their effect on vegetablescultivated with that water.UsIng AAS(atomic absorption spectrophotometer) and colorimeter the Phosphorus(PO_4-P), Nitrogen(NH_4-N), and heavy metals like Cadmium and Chromium content of eight common seasonal vegetables(Broad bean, Green chilli, Bottle gourd.Bitter gourd, Parwar, Coriander leaves, Cabbage, Cauliflower) were analysed.The vegetables were collected from Chinapukur (near Ghatakpukur-South 24 Pargana) where sewage water is used for cultivation and from Barasat (North 24 pargana) where shallow water is used for cultivation.Vegetable samples were collected during summer and winter seasons. A comparative study was made.Samples from Chinapukur indicated highest mean level of PO_4-P(168.27±0.64mg%), NH_4-N(4.76±0.04mg%), Cd(.56±0.03mg%), Cr (0.59±0.004mg%) while those from Barasat indicated the highest level of PO_4-P(80.63± 0.55mg%), NH_4-N(2.54±0.03mg%), Cd(0.55±0.02mg%), Cr(0.58±.01mg%). Comparison of results showed significant levels (p＜0.05) of all the Phosphorus, Nitrogen, Cadmium and Chromium analyzed in the vegetable samples obtained from those two places.
