Mining activities tend to pollute surface soils, water bodies, and groundwater of surrounding mining sites. These anthropogenic activities have a direct impact on the crops cultivated along with human life in and around mining areas. Mining operations produced contaminants that disrupted the physiochemical properties of water and soil. Hence analyzing the nutritional status of water and soil along with physiochemical properties is an indicator of pollution in mining areas. Odisha is the greatest producer of chromium metal, accounting for about 97% of total chromium output in India, with all of this coming from multiple chromite mines in the Sukinda block (Jajpur district). Chromite mining dust and water spills containing poisonous hexavalent chromium produce the most unfavorable conditions in water bodies and soil, rendering them unsuitable for human and plant use. The current analysis was carried out adjacent to the Sukinda block of the Jajpur district demonstrating that the examined parameters are more or less over the allowed range. The entire research explains the quality of soil and water near chromite mining areas concerning seasonal (pre‐monsoon, monsoon and post‐monsoon) and annual variation. The pH of the soil was found to be very acidic at the present research sites, which are within a radius of 3–5 km from the mining region, ranging from 4.33 to 5.24. The pH of water varied from 6.45 to 7.67 due to the mixing of chromium from the mining activity. The water bodies near the mining sites were found to be highly turbid (423–649 NTU). The test value of soil nutrients such as Nitrogen (142.89–189.12 Kg/ha.), Phosphorous (5.73–7.84 Kg/ha.), and Potassium (143.25–174.45 Kg/ha.) are comparatively very low than the normal range of soil.

“…PCA2 and PCA3 reflect the competition between GSH and chlorophyll synthesis from glutamate and the central role of glutamine/glutamate in plant metabolism (for review, view Kissen et al 2010). Further research is required to address Car content and CAT correlation since it seems to be a function of abiotic stress magnitude (Bouvier et al 1998;Pradhan et al 2013).…”

The role of Phragmites sp. in phytoremediation of wastewaters containing azo dyes is still, in many ways, at its initial stage of investigation. This plant response to the long-term exposure to a highly conjugated di-azo dye (Direct Red 81, DR81) was assessed using a vertical flow constructed wetland, at pilot scale. A reed bed fed with water was used as control. Changes in photosynthetic pigment content in response to the plant contact with synthetic DR81 effluent highlight Phragmites plasticity. Phragmites leaf enzymatic system responded rapidly to the stress imposed; in general, within 1 day, the up-regulation of foliar reactive oxygen species-scavenging enzymes (especially superoxide dismutase, ascorbate peroxidase (APX), glutathione peroxidase (GPX) and peroxidase) was noticed as plants entered in contact with synthetic DR81 effluent. This prompt activation decreased the endogenous levels of H₂O₂ and the malonyldialdehyde content beyond reference values. Glutathione S-transferase (GST) activity intensification was not enough to cope with stress imposed by DR81. GPX activity was pivotal for the detoxification pathways after a 24-h exposure. Carotenoid pool was depleted during this shock. After the imposed DR81 stress, plants were harvested. In the next vegetative cycle, Phragmites had already recovered from the chemical stress. Principal component analysis (PCA) highlights the role of GPX, GST, APX, and carotenoids along catalase (CAT) in the detoxification process.

“…Extensive use of pesticides also deteriorates the soil quality by killing the non-target organisms like earthworm and microorganisms. Effect of environmental contaminants on growth and reproduction of earthworm has been studied by Sahu (2010, 2011), on crop productivity by Pradhan et al (2013) and on soil quality and metabolic activities by Padhan and Sahu (2012) and Pradhan et al (2016). Contamination of surface and ground water, air pollution and soil pollution are some of the negative impacts of pesticide towards environmental sustainability.…”

Food consumption is one of the principal reasons of human exposures to pesticides. The research analyses the relation between pesticide contaminations and their possible adverse health impacts. Rice grain and soil samples were collected from seven blocks of Bargarh district, Odisha. Gas Chromatography‐Mass Spectrometry (GC/MS) was used for the analysis and characterization of various pesticides present in rice grain as well as in soil samples. The identified pesticide residues in rice grain samples were found to be in the sequence of ∑DDT > chlorpyrifos > chlorothalonil > vinclozolin > chlorthal‐dimethyl > endosulfan‐1 > lindane. Detected pesticide concentrations were found to exceed the Maximum Residue Limits (MRLs) set by the Codex Alimentarius International Food Standards with DDT having the highest concentration of 29.27 mg/kg (which is 292 times the MRLs) and lindane with the least concentration of 4.35 mg/kg (which is 435 times the MRLs). Estimated average daily intake (EADI) was found to be higher for DDT and lower for lindane. The Health Risk Index (HRI) for DDT was higher and lower for chlorothalonil in all the samples. Results of one‐way ANOVA reflected no significant differences in variance between the concentrations of pesticides in rice grain samples. Result showed that the residual levels of ∑DDT in soil ranged between 7.8 and 29.3 mg/kg which was the maximum concentration among all the pesticides. Lindane and chlorthal‐dimethyl showed the least concentration ranging between 1.2–4.2 and 1.6–4.1 mg/kg, respectively. DDT had the highest bioconcentration factor (BCF) ranging between 1 and 4. Lindane and endosulfan‐1 had the lowest BCF ranging between 1 and 2. BCF value of other pesticides were found between the range of 1 and 4. Bioconcentration factors of pesticides in rice and soil samples indicated that pesticides in soil could get accumulated in rice. It was observed that the health risk associated with the consumption of rice could be because of its contamination by the pesticides in the study area or of the biomagnification of pesticides from the soil. It is necessary to spreading the awareness regarding safer use, storage and disposal of pesticides should be given utmost importance at the moment as an attempt to reduce or eliminate the environmental contaminations caused by them. National authorities should enforce proper rules and regulations in order to monitor and control the vigorous use of chemical loaded pesticides in agriculture and various other fields. It would be even better to substitute the chemical pesticides with the organic component‐based Bio‐pesticides as a safer option for the mankind and its environment.
