“…ZnO NPs have received great attention worldwide and caused detoxification and transformation of metals more efficiently in plants [38]. They remain suspended in water without electrostatic forces, so they provide significant tolerance against HMs [2].…”

“…Rapid increase in industrialization and anthropogenic activities has greatly contributed towards Heavy Metals (HMs) pollution in water which affects all aspects of the ecosystem [1]. Heavy metals are metals with relatively high density that are toxic in small (e.g., Cd, Pb, Hg, As) or higher (e.g., Cu, Zn, Co) concentrations [2]. In Pakistan, no sewage treatment plants are available, so crop irrigation with HM contaminated water results in metal accumulation in grains and other tissues of the plant [3].…”

Heavy metals (HMs) are toxic elements which contaminate the water bodies in developing countries because of their excessive discharge from industrial zones. Rice (Oryza sativa L) crops are submerged for a longer period of time in water, so irrigation with HMs polluted water possesses toxic effects on plant growth. This study was initiated to observe the synergistic effect of bacteria (Bacillus cereus and Lysinibacillus macroides) and zinc oxide nanoparticles (ZnO NPs) (5, 10, 15, 20 and 25 mg/L) on the rice that were grown in HMs contaminated water. Current findings have revealed that bacteria, along with ZnO NPs at lower concentration, showed maximum removal of HMs from polluted water at pH 8 (90 min) as compared with higher concentrations. Seeds primed with bacteria grown in HM polluted water containing ZnO NPs (5 mg/L) showed reduced uptake of HMs in root, shoot and leaf, thus resulting in increased plant growth. Furthermore, their combined effects also reduced the bioaccumulation index and metallothionine (MTs) content and enhanced the tolerance index of plants. This study suggested that synergistic treatment of bacteria with lower concentrations of ZnO NPs helped plants to reduce heavy metal toxicity, especially Pb and Cu, and enhanced plant growth.

“…Various investigations demonstrated the far-reaching Cd conveyance in squander water tests gathered from different locales of Pakistan. The most noteworthy grouping of 5.35mg/L Cd in squander water announced from Korangi region, Karachi (Amin et al, 2014), exceeded the reasonable furthest reaches of 0.10 mg/L as NEQS-PAK set this amount for sewage water (Waseem et al, 2014).…”

The most important concern in developing countries like Pakistan is the contamination of groundwater because of the heavy metals from industrial waste which are affecting the ecosystem and public health. Some heavy metals such as Arsenic (As), Chromium (Cr), Nickel (Ni), Copper (Cu), Iron (Fe), Lead (Pb) and Zinc (Zn) are mostly reported in different cities of Pakistan and their concentrations are also to be found above the permissible levels of WHO. For domestic purposes and irrigation, groundwater is the main source in Pakistan. Its quality is getting poor because of the untreated discharge from industries. In the country, water-borne diseases are spreading quickly because of the use of unfiltered environmentally contaminated water as well as a lack of awareness of environmental laws.

Role of Heavy Metals and Anthropogenic Activities in Water Contamination

Water is a fundamental requirement for all living beings and it is considered as the most diverse solvent. It has a unique polarity and a distinctive set of properties due to hydrogen bonding. Water, being a universal solvent, can easily be polluted by absorption, adsorption and suspension of a lot of materials into it. Major sources of water contamination include the disposal of untreated garbage, milling, industrialization, and urbanization. Water is easily polluted by substantial metals including Lead (Pb), Arsenic (As), Copper (Cu), and Chromium (Cr). Water contamination can lead to serious illnesses and sometimes it is so hazardous that it can cause the death of a living organism.
