Acute exposure to environmentally relevant lead levels induces oxidative stress and neurobehavioral alterations in larval zebrafish (Danio rerio)
(Elsevier, 2020)The ubiquitous contamination of environmental lead (Pb) remains a worldwide threat. Improper Pb mine waste disposal from an abandoned lead-zinc mine has recently unearthed widespread Pb poisoning in children in Kabwe Zambia. ... -
Concentrations and compositions of metallic elements in commercially important marine species
(North-West University (South Africa), 2020)Metals have been in our environment since the genesis of the world and are ubiquitous in all environments. We as humans mine, utilize, and release these metals from the environment to a level that may affect chronically ... -
Concentrations and relative compositions of metallic elements differ between predatory squid and filter-feeding sardine from the Indian and South Atlantic oceans
(Elsevier, 2020)Although metallic elements occur naturally, they can occur or accumulate in organisms at levels toxic to the organism and/or their consumers. Concentrations of twenty-nine metallic elements in muscle tissue from sardine ... -
Effects of wheat-flour biscuits fortified with iron and EDTA, alone and in combination, on blood lead concentration, iron status, and cognition in children: a double-blind randomized controlled trial
(ASN, 2016)Background: Lead is a common neurotoxicant and its absorption may be increased in iron deficiency (ID). Thus, iron fortification to prevent ID in populations is a promising lead mitigation strategy. Two common fortificants ... -
Exposure of workers to nickel, copper and lead in a base metal recovery plant and laboratory
(North-West University, 2011)Objectives: The objectives of this study were to establish the extent of dermal and respiratory exposure at selected locations at a South African platinum mine. The study included exposure to lead oxide fumes in an assay ... -
Heavy metals in seaweeds from a polluted estuary in coastal Maine
(New England Botanical Club, 2017)Seaweeds (macroalgae) accumulate heavy metals from seawater and can therefore serve as biological monitors of marine pollution. In this paper, we present data on the tissue chemistry of seaweeds from the area of Callahan ... -
Hydrothermal synthesis, characterization and adsorption testing of MoS2-Zeolite for the removal of lead in an aqueous solution
(EARET, 2018)The shortage of water can be worsened by the pollution of limited water resources by industrial activities such as mining which contribute to significant level of toxic heavy metals in the environments. Heavy metals ... -
Trophic transfer and bioaccumulation of lead along soil-plant-aphid-ladybird food chain
(Springer, 2019)Lead (Pb) contamination of agroecosystems is a serious issue as Pb is a persistent pollutant that is retained in soil for long, causing toxicities to organisms. This study examines biotransfer of Pb from soils treated with ...
