“…Cd 2+ accumulation results in lung cancer, proteinuria and osteomalacia after long-term absorption 28,32 . Excessive Pb 2+ intake causes encephalopathy, inanemia, and nephropathy 33,34 . The toxicity of Cu 2+ is not as severe as Cd 2+ and Pb 2+ but exceeding safe limits of copper can also induce hemolytic anemia and necrotizing hepatitis 28,35 .…”

it is challenging to develop a low-cost household water treatment (HWt) that simultaneously deliver an effective and robust way for safe and reliable water supply. Here, we report a simple flow-through filter made by zeolite-cotton packing in a tube (Zct) as low-cost HWt device to remove heavy metal ions from contaminated water. The zeolite-cotton is fabricated by an on-site template-free growth route that tightly binds mesoporous single-crystal chabazite zeolite onto the surface of cotton fibers. As a result, the ZCT set-up with optimized diameter achieves both high adsorption efficiency, proper flow rate, reliable supply and strong stability at the same time. After flowed through the set up packed with 10 g of zeolite-cotton, 65 mL 1000 ppm Cu 2+ solution was purified down to its safety limit (<1 ppm). Notably, their efficiency remains unaltered when filtering several ions simultaneously. In a simulated purification process, 8 L of water contaminated by Cu 2+ , cd 2+ and pb 2+ could be transformed into drinking water and it enables the removal of heavy metals to concentrations of below 5 ppb (μg L −1 ). We also show that the Zct can be used for disinfection by introducing Ag-exchanged zeolite-cotton without contaminating the water with Ag ions (<0.05 ppm).Drinking water safety is one of the most serious health problems throughout the world, especially for those people in relatively undeveloped districts. Health risks may arise from consumption of water contaminated with numerous pollutants such as heavy metal ions, persistent organic pollutants, pharmaceutical waste, virus and microbial pathegens 1 . As reported by World Health Organization (WHO), nearly 2 billion people are using either un-improved drinking water source or faecally-contaminated water. Close to half a million diarrheal deaths in low-and middle-income countries are attributed to unsafe drinking-water, and the vast majority of these deaths occur among children under five 2 . Household water treatment (HWT) is an important public health intervention to improve the quality of drinking-water, particularly among those who rely on water from unimproved sources. Further, safe drinking-water is an immediate priority in most emergencies, and HWT can be an effective emergency response intervention 3,4 , for example, the project solar disinfection (SODIS) of drinking water 5-8 , which is awarded the 2020 UNESCO Prizes, is an important HWT technique approved by WHO.Unlike organic pollutants, heavy metal ions in water is hard to notice and avoid but pose a long-term threat to human. Heavy metal contaminated water usually has no visible difference as compared to safe drinking water, however, every little intake will not degrade but accumulate in human body. Even if the heavy metal-polluted water is not directly taken by human, it can also accumulate in algae, shellfish and fish, then concentrate through food chain and finally result in serious disease such as encephalopathy, hemolytic anemia or even cancer 9-11 . Those global issues have reminded people to se...

“…Toxic lead compounds have remarkably been released from the earth's crust into the atmosphere, water, soil and living organisms [3][4][5][6][7]. Of note, plants easily absorb and accumulate Pb in different tissues, this endangers human health through the food chain or inhalation [8]. Its deposition is evident in several tissues such as the liver, kidney, bones and brain [9].…”

Oxidative stress has been implicated in the pathogenesis of cognitive impairment. Lead (Pb) is a common environmental toxicant and plays a vital role in oxidative stress activation. In this study, a superoxide dismutase (SOD) and catalase (CAT) containing poly (lactic-co-glycolic acid) (PLGA) meso-particles (PLGA@SOD-CAT) were prepared to attenuate cognitive impairment via inhibiting oxidative stress in rats. It was prepared using a double emulsion (water/oil/water phase) technique to minimize the hazardous effects of Pb burden on cognitive impairment. The meso-particles antagonized the Pb-induced cognitive impairments. Behaviour, serum biochemical parameters and biomarkers of oxidative stress in rats were evaluated after they were subjected to intravenous injection with lead nitrate and PLGA@SOD-CAT. Moreover, the potential protective mechanism of PLGA@SOD-CAT was determined. Notably, PLGA@SOD-CAT appreciably agented memory impairment caused by lead nitrate and it could significantly inhibit Pb-induced oxidative stress in the blood. Furthermore, a remarkable reversion effect of cognitive impairments, including escape latency, crossing platform times and time per cent during the platform quadrant, after PLGA@SOD-CAT administration were noted. Therefore, these results suggested that the bi-enzymes platform was a superior product in eliminating Pb-induced cognitive impairments through reducing expression of Pb-associated oxidative stress, and it could potentially be applied in detoxifying heavy metals in blood circulation.
