Plants can remove or immobilize various environmental contaminants; however, little is known about the physiological mechanisms underlying responses to soil amendment with biosolids contaminated with heavy metals. We investigated the responses of cuttings of hybrid poplar clones Eridano and I-214 grown for a season in soil amended with nutrient-rich organic material from tanneries, which contai...

Globally, the demand for food is increasing day by due to rapid increase in human population. Elevated levels of metals and metalloids soils are biomagnified over time crops cultivated metal-contaminated soils, hence posing a risk chain contamination. The present investigation aimed assess metal metalloid concentrations soil, water, rice kernels which widely four districts Punjab, Pakistan, det...

Zinc is one of the more mobile metals in soil and thus involves risk entering food chain. compounds are used galvanization process, which assumed to be safe for environment. However, random events or failures such as unsealing bathtubs with liquid zinc hydrochloric acid, well violent fires industrial halls, may pose a real threat environment, including human health. Therefore, this research was...

Glyphosate-based herbicides (GBHs), consisting of glyphosate and formulants, are the most frequently applied herbicides worldwide. The declared active ingredient glyphosate does not only inhibit the EPSPS but is also a chelating agent that binds macro- and micronutrients, essential for many plant processes and pathogen resistance. GBH treatment may thus impede uptake and availability of macro- ...

Nigerian cocoa farmers mostly use copper-based fungicides to control black pod disease of Theobroma cacao. Heavy metals are potentially toxic to soil microbes and soil environment in general. Toxicity depends on chemical association in soil. For this reason, determining the chemical forms of metals in soils is important to evaluate their mobility and bioavailability. Sequential extraction was u...

Plants obtain mineral nutrients from the soil. If they are growing in soil with high levels of metals, they will take up an excess of what is needed for growth. Depending on the species, this can be detrimental to growth—or lethal—and can greatly limit the growth range of plants and the productivity of agricultural species. However, some plants have adapted to living in soil containing excess m...

The intracellular compartmentation of essential and toxic metals is of intense scientific interest because of its potential for adding to our understanding of both normal homeostatic mechanisms for metals and of the mechanisms which underlie metal-induced cell injury. High-affinity metal-binding proteins, lysosomes, and precipitates such as inclusion bodies or concretions, play major roles in t...
