Biosorbents for Removing Hazardous Metals and Metalloids †
Biosorbents for remediating aquatic environmental media polluted with hazardous heavy metals and metalloids such as Pb(II), Cr(VI), Sb(III and V), and As(III and V) were prepared from lignin waste, orange and apple juice residues, seaweed and persimmon and grape wastes using simple and cheap methods. A lignophenol gel such as lignocatechol gel was prepared by immobilizing the catechol functiona...

متن کاملCriticality of metals and metalloids.
Imbalances between metal supply and demand, real or anticipated, have inspired the concept of metal criticality. We here characterize the criticality of 62 metals and metalloids in a 3D "criticality space" consisting of supply risk, environmental implications, and vulnerability to supply restriction. Contributing factors that lead to extreme values include high geopolitical concentration of pri...
متن کاملToxic metals and metalloids in dietetic products.
AIM To determine the concentrations of cadmium, lead, mercury, and metalloid arsenic in the samples of some dietetic products marketed in Croatia, and to compare the values obtained with maximum allowed amounts (MAA) according to the law. METHOD Metal and metalloid concentrations were measured in 30 dietetic products from the group of industrial food supplements and food additives. The measur...
متن کاملMetabolic interactions between metals and metalloids.
The experimental evidence obtained with laboratory animals which shows that the toxicities of lead, cadmium, and mercury can be increased by deficiencies of certain essential nutrients such as calcium, iron, zinc, and selenium is briefly reviewed. An idealized theoretical model which indicates the possible influence of multiple nutritional deficiencies on the toxicity of a heavy metal is presen...
