Biosorbents Removed Copper Heavy Metal from Agricultural Land Cultivated with Vigna radiata (Mung Bean)
AI summary Read the abstract
This study evaluated orange peels, pomegranate peels, and peanut peels as biosorbents for removing copper from agricultural water used to irrigate mung beans, finding orange peel achieved 90% copper removal. Plants irrigated with biosorbent-treated water showed improved growth and no signs of metal toxicity.
Background. Heavy metals in excessive levels are hazardous to ecosystems as they can bioaccumulate in organisms, have toxic effects on biota, and even cause mortality in most life forms. Methodology. The present study consists of two studies; initially, different concentrations of copper were biosorbed by using 1 gm powder of various biosorbents such as orange peels (OP), pomegranate peels (POP), and peanut peels (PP). Furthermore, the biosorbed water was used to irrigate soil when the mung beans were cultivated. The growth parameters of plants growing under induced copper stress and treated with different bioabsorbed waters were also evaluated. Results. The results revealed that, among all biosorbents, the copper biosorption capacity of orange peels was maximum (90%), followed by pomegranate peel. The results of the second experiment exhibited that the plants irrigated with biosorbed water did not show metal toxicity. A remarkable increase in shoot length, shoot fresh weight, and shoot dry weight was observed (29.8 cm, 15.4 g, and 14 g, respectively) when exposed to biosorbent water with peanut peels + 200 mg kg−1 (Cu2+). Similarly, pomegranate peel biosorbed water turned out to be an effective treatment to enhance root length, root fresh weight, and root dry weight (6.81 cm, 4.07 g, and 2.66 g, respectively) and resist against induced heavy metal stress conditions at higher concentration (200 mg kg−1). Furthermore, orange peel biosorbed water elevated the total chlorophyll content and soluble sugar content in mung bean (1.56 mg/g and 1.89 mg/g). The highest tolerance index of mung bean plant grown under the stress of Cu2+ metal was induced by orange peel biosorbed water. Conclusion. Biosorption is an environmentally friendly approach to mitigate heavy metals from the water. The studies showed that agricultural wastes have enough bioabsorption potential and should be used to absorb the heavy metal present in water.

AI summary Read the abstract
Researchers developed an activated carbon filter material from raffia palm seed shells to remove microplastics, cadmium, and copper from polluted surface water. The filtration system successfully reduced plastic contamination, and the carbon material demonstrated effective adsorption of heavy metals from simulated wastewater. The study presents a low-cost, locally sourced approach to water treatment that could help address multiple contaminants simultaneously.

Polyethylene Microplastics Modulate the Copper Adsorption–desorption Processes in Agricultural Soils
AI summary Read the abstract
Batch adsorption experiments showed that adding 1% polyethylene microplastics to two agricultural soils modestly increased copper adsorption capacity while altering desorption behavior in soil-type-dependent ways. This matters because microplastic accumulation in farmland can disrupt heavy metal cycling, potentially increasing bioavailability of toxic metals like copper in crops and the humans and animals that consume them.
