测量,映射,表征土壤性质是确定土壤质量的关键步骤。连续使用无机肥料,杀虫剂,废水排放,和渗滤液导致土壤退化和饮用水和食物的污染,最终导致土壤污染和对人类健康的不良影响。这项研究旨在监测从卢迪亚纳十个不同农田收集的农业土壤样品的土壤质量,旁遮普(印度),在佛陀Nullah附近,萨特莱伊河支流。在研究过程中估算了土壤样品的理化特性和重金属含量。结果表明,所有农业土壤样品的性质均为微碱性。土壤养分如硝酸盐,磷酸盐,钾的范围为0.06至0.11毫克/克,0.03至0.08毫克/克,和0.04至0.15mg/g。镉等重金属的含量(mg/kg),铬,钴,铜,在大多数土壤样品中,铅都高于允许的限值。洋葱根染色体畸变试验用于遗传毒性研究,表明Hambran(HBN),大约一个网站。12.9公里的佛陀Nullah,诱导的最大基因毒性作用,即,46.7%的洋葱根尖细胞异常细胞。统计分析显示重金属Cr、Cu,和Ni(p≤0.05和p≤0.01),在洋葱中引起的总染色体畸变。
Surveying, mapping, and characterizing soil properties are the critical steps in designating soil quality. Continuous use of inorganic fertilizers, pesticides, wastewater discharge, and leachates cause soil degradation and contamination of potable water and food ultimately leading to soil pollution and ill effects on human health. This study was undertaken to monitor the soil quality of agricultural soil samples collected from ten different agricultural fields in Ludhiana, Punjab (India), near Buddha Nullah, a Sutlej River tributary. Physico-chemical characteristics and heavy metal contents of soil samples were estimated during the study. The obtained results showed that all the agricultural soil samples were slightly alkaline in nature. Soil nutrients such as nitrates, phosphates, and potassium ranged from 0.06 to 0.11 mg/g, 0.03 to 0.08 mg/g, and 0.04 to 0.15 mg/g respectively. The contents (mg/kg) of heavy metals such as cadmium, chromium, cobalt, copper, and lead were observed to be above the permissible limits in most of the soil samples. Allium cepa root chromosomal aberration assay was used for genotoxicity studies which has shown that Hambran (HBN), a site approx. 12.9 km of the Buddha Nullah, induced maximum genotoxic effects, i.e., 46.7% aberrant cells in root tip cells of Allium cepa. The statistical analysis revealed the positive correlation of heavy metals like Cr, Cu, and Ni (at p ≤ 0.05 and p ≤ 0.01) with the total chromosomal aberrations induced in Allium cepa.
