Heavy Metal Accumulation in Rice and Aquatic Plants Used as Human Food: A General Review

open access: yesToxics, 2021
Aquatic ecosystems are contaminated with heavy metals by natural and anthropogenic sources. Whilst some heavy metals are necessary for plants as micronutrients, others can be toxic to plants and humans even in trace concentrations.

Phyto-assessment of Soil Heavy Metal Accumulation in Tropical Grasses [PDF]

open access: yes, 2016
Tropical grasses are fast growing and often used for phytoremediation. Three different types of tropical grasses: Vetiver (V. zizanoides), Imperata (I. cylindrical) and Pennisetum (P.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

THE INFLUENCE OF MERCURY POLLUTION ON THE GROWTH OF BIO-INDICATOR PLANTS [PDF]

open access: yes, 2018
Heavy metals are found naturally in the earth, and become concentrated as a result of human caused activities. Common sources are from mining and industrial wastes, vehicle emissions, lead- acid batteries, fertilisers, paints, treated woods, aging ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Research progress on intestinal probiotics alleviating chronic heavy metal toxicity

open access: yes环境与职业医学, 2022
Human activities, especially industrial production, have aggravated the pollution of heavy metals in the environment, and especially after disrupting the food chain, such pollution can cause varying degrees of heavy metal poisoning in human beings ...

Accumulation of heavy metals in agricultural soil irrigated by sewage sludge and industrial effluent (case study: Agh ghallah industrial estate) [PDF]

open access: yes, 2015
Background and purpose: Industrial effluent and sewage sludge are used as fertilizer since they contain high levels of nutrient. The main pollutant in industrial effluent is heavy metals.
