The use of antibiotic agents as growth promoters was banned in animal husbandry to prevent the selection and spread of antibiotic resistance. However, in addition to antibiotic agents, heavy metals used in animal farming and aquaculture might promote the spread of antibiotic resistance via co-selection. To investigate which heavy metals are likely to co-select for antibiotic resistance in soil ...
Soil pollution is a highlighted concern of modern society, particularly in developing countries. The Drosh-Shishi valley, which hilly region near Afghanistan with land area around 15,000 km2, situated the south Chitral District (Pakistan) and has population approximately 450,000. Nowadays, this being explored for soil pollution, specifically heavy metals pose potential risk to human health. The...
Heavy metals are metallic elements which have a high atomic weight and a density much greater (at least 5 times) than water. There are more than 20 heavy metals, but four are of particular concern to human health: lead (Pb), cadmium (Cd), mercury (Hg), and inorganic arsenic (As). According to the U.S. Agency for Toxic Substances and Disease Registry. These four heavy metals are four of the top ...
BACKGROUND Cadmium (Cd), lead (Pb) and arsenic (As) are common environmental contaminants that have been associated with lower birthweight. Although some essential metals may mitigate exposure, data are inconsistent. This study sought to evaluate the relationship between toxic metals, nutrient combinations and birthweight among 275 mother-child pairs. METHODS Non-essential metals, Cd, Pb, As,...
The present study evaluated the potentials of phytoremediation and biomonitoring potentially toxic metals (PTMs) (Zn, Ni, Fe, Pb, Cu) in mangrove leaves Rhizophora apiculata from tropical ecosystem Sepang Besar River Lukut River, Peninsular Malaysia. Overall, studies concluded that (a) levels essential Cu, Zn lamina are significantly (p < 0.05) higher than MP, (b) Pb Ni MP lamina, (c) has be...
