A critical analysis of wastewater use in agriculture and associated health risks in Pakistan

Natasha et al.

Summary: Freshwater shortage and contamination is a major global issue impacting socioeconomic values. This review focuses on the use of wastewater for crop production in semiarid and arid areas, highlighting its potential as a source of essential nutrients but also its negative effects due to toxic substances such as heavy metals. The case study of Pakistan, which faces severe freshwater scarcity, examines the use of untreated wastewater in agriculture and its impact on soil chemistry and human health. The review provides data analysis and proposes solutions and future perspectives for addressing the challenges.

Unrevealing arsenic and lead toxicity and antioxidant response in spinach: a human health perspective

Natasha et al.

Summary: The study shows that arsenic and lead are more toxic to spinach, leading to high carcinogenic and non-carcinogenic risks. Additionally, metal accumulation affects spinach growth and induces oxidative stress.

Arsenic-induced oxidative stress in Brassica oleracea: Multivariate and literature data analyses of physiological parameters, applied levels and plant organ type

Natasha et al.

Summary: Plant redox homeostasis plays a crucial role in governing the uptake, toxicity, and tolerance mechanisms of toxic trace elements. The exposure to arsenic in Brassica oleracea caused pigment toxicity and oxidative burst, with As mainly retained in roots leading to increased H2O2 content. Various antioxidant enzymes were activated in response to As-induced oxidative stress, showing differential responses in different plant organs and treatment levels.

The groundwater arsenic contamination in the Bengal Basin-A review in brief

Arpan Sarkar et al.

Summary: The presence of arsenic in the groundwater of the densely-populated Bengal Basin has caused great misery for millions of people. The high levels of arsenic are primarily found in the shallow aquifers, where the redox conditions and biogeochemical activities allow the arsenic to be released from the grey sands. The deep aquifers generally have lower or no arsenic, and the infiltration of arsenic from the shallow aquifers is mainly caused by irrigation pumping.

Risk assessment of trace element accumulation in soil and Brassica oleracea after wastewater irrigation

Ali Haider Shah et al.

Summary: The present study aimed to evaluate the health and ecological risks associated with trace element accumulation in Brassica oleracea under wastewater irrigations from different areas. The study found that mixing wastewater with fresh/groundwater for irrigation increased the concentrations of trace elements in soil and plants, as well as the associated risk indices. However, mixed wastewater treatments were effective in minimizing trace element concentration in plants and reducing associated health risks.

Natural arsenic source, migration, and flux in a catchment on the Southern Tibetan Plateau

Li Zhou et al.

Summary: This study reveals the non conservative behavior of arsenic in the upper reaches of river flows in a geothermal field on the Tibetan Plateau. The main stream waters have a high concentration of dissolved arsenic, while most tributaries have a relatively low concentration. Geothermal spring discharge is the main source of dissolved arsenic, and the weathering of rocks becomes the dominant source during the high-flow period.

As(III) adsorption onto Fe-impregnated food waste biochar: experimental investigation, modeling, and optimization using response surface methodology

Fritz Ndumbe Lyonga et al.

Summary: Biochar derived from food waste was modified with Fe to enhance its adsorption capacity for As(III). The optimized Fe-impregnated food waste biochar (FeFWB) showed superior adsorption performance at lower temperature, Fe concentration, and pH levels, demonstrating high adaptability under different conditions.

Health risks of arsenic buildup in soil and food crops after wastewater irrigation

Natasha et al.

Summary: This study examined the impact of using municipal wastewater for irrigation on arsenic levels in soil and food plants in Pakistan, finding potential health risks in certain areas, particularly for children consuming wheat crops. It recommends the use of diverse food crops in the study area to minimize the risk of arsenic exposure and poisoning. The study also highlights the importance of considering future perspectives on wastewater use, potential human exposure to metal(oids), and associated health concerns at local and global levels.

Risk assessment of potentially toxic metal(loid)s in Vigna radiata L. under wastewater and freshwater irrigation

Hasnain Anwar et al.

Summary: This study investigated the impact of municipal water irrigation in agriculture on plants, revealing that plants accumulated potentially toxic metals mainly in roots, leading to increased oxidative stress in mung beans. The irrigation treatments posed potential risks to human health due to elevated levels of toxic metals, highlighting the unsuitability of mixed wastewater and freshwater use in crop irrigation.

Effect of soil amendments on trace element-mediated oxidative stress in plants: Meta-analysis and mechanistic interpretations

Muhammad Shahid

Summary: This study critically elucidated the impact of soil amendments on trace-element-induced oxidative stress in plants, revealing distinct variations under different conditions. Specifically, when trace elements and soil amendments are co-applied, plant tolerance and growth parameters are enhanced, while stress parameters are reduced.

Ideal pH for the adsorption of metal ions Cr6+, Ni2+, Pb2+ in aqueous solution with different adsorbent materials

Luisa P. Cruz-Lopes et al.

Summary: Industrialization leads to increased release of heavy metals into the environment. Decontamination through adsorption using lignocellulosic wastes is a viable solution, and controlling the pH of the solution can result in more efficient removal of heavy metals. Experiment results showed different behaviors of biosorbent materials with different metals, indicating potential for decontaminating wastewater to varying degrees.
