Heavy metal and metalloid poisoning in the environment food has piqued public’s interest since it poses significant hazards to ecological system human health. In food, several metals, including cadmium (Cd), lead (Pb), mercury (Hg), tin (Sn), manganese (Mn), aluminium (Al), metalloids, arsenic (As), antimony (Sb), selenium (Se), pose a severe threat It is of utmost importance detect even minute quantities these toxic elements this must be efficiently determined understand their risk. Several...
Abstract Cereals and cereal-based foods continue to be basic in all diets. Despite being known for their high nutritional value; they can also contain contaminants (hazards) such as toxic metals. This study assesses the Cd, Pb Hg dietary exposure from cereals derivatives marketed Madeira Azores characterizes risks by evaluating Cd intake contributions tolerable intakes estimating Margin of Exposure (MOE) case Pb. In Madeira, metals follow descending order > Hg. stands out having highest...
Bioaccumulation is the process by which living organisms accumulate substances, such as pesticides, heavy metals, and other pollutants, from their environment. These substances can in organism's tissues over time, leading to potential health risks. occur both aquatic terrestrial ecosystems, have a significant impact on of humans wildlife. The objective this study find out if concentrations metals tuna species Canary Islands are suitable for human consumption they pose risk. Fifteen samples...
Sea anemones have often been used as bioindicators of contamination because they are semisessile organisms that rarelly leave their niche, which is why conducive to affecting the ecosystem at local level. The objective this work determine whether concentrations heavy metals and trace elements in anemone Anemonia sulcata vary depending on source present. In 2021 seventy specimens were collected five sampling points fourteen each point (Control Zone, Thermal Power Plant, Sewage Pipe, Harbour...
Tuna, due to their position in the food web, serve as excellent biomonitors for assessing health of marine ecosystems. Analyzing organs and tissues provides valuable insight into element concentrations, tuna possess capacity bioaccumulate pollutants. In present study, 12 trace elements metals (Al, B, Cd, Co, Cr, Cu, Fe, Li, Mo, Ni, Pb, Zn) were analyzed dorsal fin spines samples four species: Katsuwonus pelamis, Thunnus albacares, obesus thynnus from individuals captured surrounding waters...
Fluoride is an anion that widely distributed in nature whose main source volcanic emissions. This reaches humans mainly through water and can produce beneficial effects at certain doses, with toxic occurring high doses. There are regions of the world stand out for their concentrations fluoride, as it has produced endemic fluorosis population. case Tenerife, one islands Canary archipelago origin. The aims this study to perform a historical review fluoride region assess current levels....
The concentrations of 20 metals (Na, K, Ca, Mg, V, Mn, Fe, Cu, Zn, Cr, Mo, Co, B, Ba, Sr, Ni, Si, Al, Pb, and Cd) in cage-reared hens’ eggs have been determined this study using inductively coupled plasma atomic emission spectroscopy (ICP-OES). There were significant differences the metal content depending on edible part egg, with yolk having greater metals. daily consumption (24.3 g/person/day for children 31.2 adults) contributes to intake trace metals, notably Fe (3.8% children, 3.2%...
Underwater volcanic eruptions are a type of natural contamination that affect all marine organisms at local level. These usually begin and end degassing stage the volcano that, although they do not magnitude magma emanation, to lesser degree locally, such as cephalopods due their metabolism trophic level, good bioindicators contamination. A total 180 samples three species were collected for study: sixty Sepia officinalis, Octopus vulgaris Loligo in area submarine El Hierro, Tenerife...
Sports nutrition supplementation is a widespread practice. Whey protein supplements contribute not only to intake but also dietary exposure minerals. The labelling present provides the percentage of and rarely refers other components, such as potentially toxic elements B, Cu, Mo, Zn, V that tolerable upper levels set by European Food Safety Authority. declared on supplement was checked using Kjeldahl method, Ca, Mg, K, Na, Ba, Co, Cr, Sr, Fe, Li, Mn, Ni, V, Al were analyzed ICP-OES with aim...
