The extensive use of heavy metals and nanoparticles (NPs) has led to their release into the environment that might have negative impacts on both organisms and the environment. In this study, the molecular responses of wheat seedlings to silver nitrate and silver nanoparticles (AgNPs) were assessed by transcript accumulation analysis of genes coding for products potentially involved in heavy met...

Human contact with mercury has been ongoing for centuries and was previously considered a legitimate means of treating different cutaneous and systemic conditions. Toxicity from this heavy metal may occur from exposure to elemental, inorganic, and organic forms of mercury. This article outlines the signs and symptoms of mercury poisoning and the different clinical conditions with assorted cutan...

Lead is a dangerous heavy metal which is widely spread in the environment. Lead content in the air, food and tap water has increased several folds during recent years due to extensive use of this metal in petrol, paints, battery and other industries (Tuormaa, 1995). Despite of attempts for reducing the exposure to this metal, there are still some reports of cases with severe lead toxicity (Hers...

Technogenic activities (industrial-plastic, textiles, microelectronics, wood preservatives; mining-mine refuse, tailings, smelting; agrochemicals-chemical fertilizers, farm yard manure, pesticides; aerosols-pyrometallurgical and automobile exhausts; biosolids-sewage sludge, domestic waste; fly ash-coal combustion products) are the primary sources of heavy metal contamination and pollution in th...

There has been much research into autism or autistic spectrum disorder (ASD) and room for considerable conjecture regarding the etiology of these disorders remain. ASD is marked by a complex interaction between environmental factors and genetic predisposition, including epistasis. This manuscript argues that changes in oxidative metabolism, thiamine homeostasis, heavy metal deposition and cellu...

background: the entrance of toxic compounds into wastewater treatment plants (wwtps) can induce disorder in their biological units. therefore, it is necessary to determine the sources of toxic wastewaters. in this study, the toxicity of the wastewater of 3 metal plating industries was assessed using sequencing batch reactor (sbr) bacteria. methods: to obtain the 1-1000 ml/l concentrations, the ...

introduction: biosorption of heavy metals can be an effective process for the removal of heavy metal ions from aqueous solutions. also, living lichens are known to accumulate metals across their surface. materials and methods: in this study, the biosorption of cadmium ions cd (ii) by the lichens acarospora strigata, lecanora muralis and caloplaca aurantia was investigated in aqueous solution in...

Heavy metals are toxic and non-biodegradable environmental contaminants that seriously threaten human health. The remediation of heavy metal-contaminated water soil is an urgent issue from both biological points view. Recently, nanomaterials with excellent adsorption capacities, great chemical reactivity, active atomicity, environmentally friendly performance have attracted widespread interest ...

Soil enzyme activities are greatly influenced by soil properties and could be significant indicators of heavy metal toxicity in soil for bioavailability assessment. Two groups of experiments were conducted to determine the joint effects of heavy metals and soil properties on soil enzyme activities. Results showed that arylsulfatase was the most sensitive soil enzyme and could be used as an indi...
