Heavy metal poisoning: management of intoxication and antidotes

Abstract: Abstract. Of the known elements, nearly 80% are either metals or metalloids. The highly reactive nature of most metals result in their forming complexes with other compounds such oxygen, sulfide and chloride. Although this reactivity is the primary means by which they are toxic, many metals, in trace amounts, are vital to normal physiological processes; examples include iron in oxygen transport, manganese and selenium in antioxidant defense and zinc in metabolism. With these essential metals toxicity occurs wh… Show more

“…Essential elements toxicity occurs when concentrations are either too low or too high. For other elements, such as arsenic, mercury, lead and thallium, there are no physiological concentrations that are beneficial, and these elements only have the potential to cause toxicity (Rusyniak et al 2010). For instance, several toxic elements have been associated with impaired human semen quality and sperm DNA integrity at relatively low levels .…”

“…Extended exposure to these elements causes their retention and internal imbalances within the body, which consequently starts using them as substitutes for essential elements; Pb can substitute for calcium (Ca), Cd readily substitutes for Zn, and aluminum (Al) may substitute for almost all trace elements (Weber and Konieczyński 2003). HMs accumulated in tissues disrupt a vast array of metabolic processes by altering the pro-oxidant/antioxidant balance (bind to free sulfhydryl groups resulting in inhibition of glutathione metabolism) and interfering with the activity and function of several enzymes and hormones (Rusyniak et al 2010). In turn, disruption of the metabolism of carbohydrates, proteins, amino acids, lipids, neurotransmitters, and hormones increases susceptibility to infections; adversely affects the central nervous system, memory, and reproductive system; and results in mutagenesis, toxicity to skin, bones and teeth, kidney damage, and liver dysfunction (Mukke and Chinte 2012).…”

“…The main demerit of LucFF is, unlike fluorescent reporter proteins, it does not allow to develop live cell assays and is restricted to a single data point in each experiment. 20 The automation is hindered because of the step required for the addition of substrate for the LucFF assay. Moreover, the signal associated with luminescence measurement is transient, and it is very critical to measure just after the addition of the substrate.…”
