Cadmium is an extremely dangerous heavy metal to humans, yet our environment is full of cadmium sources that we are subjected to everyday and this often leads to people having cadmium toxicity which is evident in the large number of cases of kidney, heart disease, osteomalacia (softening of the bones) and lung cancer that result from cadmium toxicity. Bone changes appear to be secondary to renal tubular dysfunction. Cadmium induces oxidative stress, to resulting in the damage of proteins, lipids, and DNA. Toxicol. It has been also demonstrated that environmental cadmium may be a risk factor for osteoporosis. Mechanisms of cadmium induced genomic instability. Science of The Total Environment, Vol. Cadmium is a heavy metal that causes direct harm to humans in several forms. Res. Clinical uremia is rare, but decreased filtration reserve capacity can be demonstrated in cadmium workers with normal baseline GFR and serum creatinine. Much work is underway to define the “critical renal concentration” at which cadmium-induced renal damage occurs. Course: WB 1096 1. Any biological function of cadmium in mammals is not known. These mothers also had infants with birth weights that were lower than those of newborns of unexposed women but this difference was felt to be due to the increased incidence of early deliveries (Nishijo et al. Massányi P, Massányi M, Madeddu R, Stawarz R, Lukáč N. Toxics. 1993). Cadmium is increasingly used in solar panels as cadmium telluride. special exposure scenarios such as hobbies. Sinicropi M.S., Caruso A., Capasso A., Palladino C., Panno A., Saturnino C. Heavy metals: Toxicity and carcinogenicity. Cadmium can accumulate in, liver, kidneys and bones, which may serve as sources of exposure later in life. The most recent (Mannino et al. Environ. Alongside the three other heavy metals – arsenic, lead and mercury – cadmium appears in … Some of these are are extremely toxic and dissolve easily in water, making them dangerous to humans. Associations between Maternal Cadmium Exposure with Risk of Preterm Birth and Low after Birth Weight Effect of Mediterranean Diet Adherence on Affected Prenatal Outcomes. Pulmonary and renal toxicity have been documented for short-term inhalation exposure of animals to cadmium and cadmium compounds (USAF, 1990). 2016;238:45–67. Chronic cadmium inhalation is also suspected to be a possible cause of lung cancer (Sorhan and Esmen 2004; Verougstratete et al. Exposure to cadmium primarily occurs through the ingestion of contaminated food and water and, to a significant extent, through inhalation and cigarette smoking. USA.gov. Mutat Res. 2005; Kobayashi et al. INTRODUCTION. Clipboard, Search History, and several other advanced features are temporarily unavailable. 1990). In the past, several studies of occupationally and environmentally exposed populations have shown that the threshold for renal damage occurred at urinary cadmium levels of 2-4 nmol/mmol creatinine (Buchet et al. Toxic effects on the kidney from chronic cadmium exposure are dose related. 6. Study limitations, such as small sample size, lack of suitable cohorts, and failure to control for smoking and other confounding effects, render the association uncertain. It is naturally occurring in the environment as a pollutant that is derived from agricultural and industrial sources. Cadmium, which is poorly metabolized, is filtered and reabsorbed in the renal proximal tubules, resulting in its bioaccumulation in target organs with a half-life of about 10 to 30 years. Rev. Cadmium is used in nickel-cadmium batteries; these are some of the most popular and most common cadmium-based products. Review of cadmium transfers from soil to humans and its health effects in the Jamaican environment. Cadmium nephropathy is an important determinant of mortality in cadmium workers. 11. Cadmium has been shown to manifest its toxicity in human and animals by mainly accumulating in almost all of the organs and kidney is the main target organ where it is concentrated mainly in cortex. However, other studies have not shown cadmium to cause pre-term labor (Zhang et al. We have included recent data which were published from 2000 onward in this review. 2002). It is naturally occurring in the environment as a pollutant that is derived from agricultural and industrial sources. Published Search}, author = {}, abstractNote = {The bibliography contains citations concerning the effects of cadmium on humans. Cadmium is a naturally occurring metal. The data were collected using various websites and consulting books, reports, etc. Cadmium (Cd) is a highly toxic heavy metal and has spread widely in the environment in recent decades. Toxic effects on the kidney are dose-related (Mueller et al. Data from human studies suggest a latency period of approximately 10 years before clinical onset of renal damage, depending on intensity of exposure. Acute poisoning, depending on the mode of exposure, can cause life-threatening respiratory or gastrointestinal symptoms in the absence of immediate supportive therapy, while chronic toxicity, mostly through occupational exposure may lead to renal failure, osteomalacia and increase the risk for cardiovascular disease. Cadmium (Cd) is a metal that can cause severe acute or chronic toxicity in humans. The women were exposed through their diet because the region of Japan in which they resided was contaminated with cadmium (Ikeda et al. The main target in cadmium intoxication. Cadmium exerts toxic effects on the kidney, the skeletal system and the respiratory system and is classified as a human carcinogen. Environmental exposure of cadmium occurs via food, occupational … 2000). The International Agency for Research on Cancer (IARC) classifies cadmium in Group 1: carcinogenic to humans and the US Environmental Protection Agency (EPA) has determined that cadmium is a probable human carcinogen by inhalation. In fact, cadmium is re-absorbed by the kidney thereby limiting its excretion. Cadmium (Cd) is a toxic non-essential transition metal that poses a health risk for both humans and animals. Some investigators believe cadmium also exerts an inhibitory effect on calcium absorption from the gastrointestinal tract. Several studies have looked at this topic. Arch. Heavy metal poisoning: the effects of cadmium on the kidney. At this time, the evidence of cadmium's effects on pregnancy is inconsistent and requires further investigation. CE Renewal Date: May 12, 2011 It is also a carcinogen by inhalation. Cadmium -New Aspects in Human Disease, Rice Contamination, and Cytotoxicity- is a valuable resource for scientists involved in heavy metal toxicology, botanical sciences, and regulatory sciences. 400, Issue. It is widely accepted (WHO 1992, ATSDR 1997) that approximately 2% to 6% of the cadmium ingested is actually taken up into the body. B. It is usually present in the environment as a mineral combined with other elements like oxygen, chlorine, or sulfur. Cadmium is under preliminary research for its toxicity in humans, potentially affecting mechanisms and risks of cancer, cardiovascular disease, and osteoporosis. D. 300 mg/m3. NIH Cadmium can travel long Possible lung cancer. 400, Issue. This review provides an update on the effects of Cd exposure on human health, focusing on the cellular and molecular alterations involved. Cadmium-induced toxicity in mitochondria is mainly attributable to the formation of Cd-thiol complexes, resulting in dysfunction of mitochondria and subsequent injury (Martínez-Flores, 2016). There have also been studies examining the role of cadmium in the development of chronic obstructive pulmonary disease (COPD) in smokers (ATSDR 1999). A. It mainly affects kidneys and bones. Environ. Please enable it to take advantage of the complete set of features! Many investigators have considered the toxic effects of exposure to metals such as arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg), and there has been substantial expenditure on measures to reduce human exposure. Other experts believe that the renal tubular dysfunction associated with cadmium is irreversible (Iwata et al. 2010 Oct;23(5):783-92. doi: 10.1007/s10534-010-9328-y. Chronic cadmium poisoning affects people that come into contact with this metal on duty. 1,2. Sufficient cadmium exposure can also lead to decreased GFR and chronic renal failure manifested by: Kidney stones are more common in cadmium-exposed populations, especially in exposed workers. Cadmium (Cd) is an ubiquitous environmental pollutant that causes a variety of adverse effects in both humans and animals. Like all heavy metals, it accumulates in the bodies of most organisms (including humans). As stated before, this can include. Cadmium (Cd) toxicity is highly detrimental for the human and largely originated from faulty industrial and agricultural practices. CE Original Date: May 12, 2008 Most cases of cadmium toxicity are due to chronic exposure. Cadmium is also dangerous if inhaled in its dust or powder form. The major target for acute cadmium toxicity is liver, whereas severe nephrotoxicity has been observed in chronic cadmium poisoning. -, Genchi G., Sinicropi M.S., Carocci A., Lauria G., Catalano A. Mercury exposure and heart diseases. 2014;229:1–18. This process renders the cadmium insoluble in water, which greatly limits absorption by the human body. At moderate, usual occupational levels of exposure, increased excretion of high-molecular-weight proteins, such as albumin and transferrin, are early signs of glomerular damage from cadmium. (Latest citations from the Life Sciences collection database).  |  1999). It is classified as a human carcinogen. Cadmium inhibits membrane-bound enzymes [2]. Toxicol. Cellular mechanisms of cadmium-induced toxicity: a review. Chronic cadmium poisoning from the consumption of food occurred in the 1950s in cadmium-polluted areas in Japan. Acute human cadmium poisonings are very rare and mainly due to suicidal oral intake of cadmium compounds, accidental cadmium contamination of food items, or accidental inhalation of cadmium oxide fumes during welding or flame cutting cadmium-coated metal. To review relevant content, see Respiratory Effects in this section. Xie et al. Cadmium accumulates in plants and animals with a long half-life of about 25-30 years. Download Printer-Friendly version [PDF - 490 KB], Upon completion of this section, you will be able to, This section describes the health effects that have been found in some individuals who have been exposed chronically to high levels of cadmium. Cadmium is under preliminary research for its toxicity in humans, potentially affecting mechanisms and risks of cancer, cardiovascular disease, and osteoporosis. NCI CPTC Antibody Characterization Program, Sinicropi M.S., Amantea D., Caruso A., Saturnino C. Chemical and biological properties of toxic metals and use of chelating agents for the pharmacological treatment of metal poisoning. Recent work also suggests that exposed children might be a susceptible population (Trzcinka-Ochocka et al. Cadmium's toxicity primarily affects the lungs and kidneys, with secondary effects on the skeletal system. There is conflicting data that chronic cadmium exposure may cause mild anemia. Stone formation probably results from cadmium-induced renal damage leading to hypercalciuria and hyperphosphaturia, but other contributing factors may include uric aciduria, reduced urinary citrate, and renal tubular acidosis. 1999). Tohoku J Exp Med. It targets many systems of the body and can cause a multitude of different symptoms. C. Destruction of the olfactory epithelium and subsequent anosmia. Cadmium acts on mitochondria, awakening the enzymatic and non-enzymatic antioxidative defenses. Cadmium (Cd) has been known as a toxic metal to beans, beets, and turnips, also it has the ability to accumulate in plants and soils to values that may be harmful to human… Anosmia and yellowing of teeth have been reported. 3. This review summarizes current knowledge about Cd contamination of leafy vegetables, its toxicity, exposure, health risks, and approaches to reducing its toxicity in humans. It is generally present in the environment at low levels; however, human activity has greatly increased levels in environmental media relevant to population exposure. Chronic cadmium inhalation may result in impairment of pulmonary function with obstructive … Human exposure mainly arises from combustion of fuels, plants, and waste, and consumption of adventitious cadmium present in food and water [].Humans and animals breathe cadmium-containing particles (mainly the oxide) and ingest cadmium complexes with their food and drinks. Satoh M(1), Koyama H, Kaji T, Kito H, Tohyama C. Author information: (1)Environmental Health Sciences Division, National Institute for Environmental Studies, Tsukuba 305-8506, Onogawa, Japan. 2000). The study authors found a negative correlation between urinary cadmium and bone density. It is classified as a human carcinogen. The Cadmibel study, a prospective population study looking at the health effects of low-level environmental exposure to cadmium in the general population, found no effect of cadmium on the blood pressure of study subjects (Stassen J et al. Epub 2010 Mar 31. The main target in cadmium intoxication. 2012 May 1;733(1-2):69-77. doi: 10.1016/j.mrfmmm.2011.09.002. Cadmium Toxicity: New Aspects in Human Disease, Rice Contamination, and Cytotoxicity: Himeno, Seiichiro, Aoshima, Keiko: 9789811336294: Books - Amazon.ca Cadmium is a heavy metal that is incredibly toxic to the human body and ever-present in our environment. Heavy Metals Contamination in Shellfish: Benefit-Risk Evaluation in Central Italy. Cadmium, a natural element in the Earth's crust, is actually present in miniscule amounts in all soil and rocks, according to the Agency for Toxic Substances and Disease Registry (ATSDR). 2004; Watanabe et al. because it is easier to apply, while in the oral route, Cd poisoning in humans is best represented by allowing the metal to pass through the digestive system and be absorbed into the bloodstream. cigarette smoking since the tobacco plant takes up cadmium avidly from the environment. Lifetime prevalence rates of 18%to 44% have been found, compared to rates less than 5% in control populations. Cadmium has a diversity of toxic effects including nephrotoxicity, carcinogenicity, teratogenicity and endocrine and reproductive toxicities. Since there are a plethora of studies on cadmium toxicity and poisoning in laboratory animals and humans, we have limited this review to studies that are relevant to human health issues by focusing on carcinogenicity, genotoxicity, circulatory disease, nephrotoxicity and life expectancy. Cadmium, arsenic, lead and mercury are noted to have caused major human health problems all over the world [1]. Acute cadmium poisoning can develop during the ingestion of water contaminated by this metal. The epigenetics present themselves as chemical modifications of DNA and histones that alter the chromatin without changing the sequence of the DNA nucleotide. Pseudofractures are spontaneous fractures that follow the distribution of stress in normal skeleton or occur at sites where major arteries cross the bone and cause mechanical stress through pulsation. Cadmium's carcinogenic effects have been demonstrated in experimental animals; evidence in humans is somewhat less conclusive. Biometals. In fact, the effect of smoking on peripheral artery disease decreased after adjustment for cadmium levels suggesting that the effect of smoking on the development of peripheral artery disease may be partially mediated by cadmium. This site needs JavaScript to work properly. Cadmium toxicity occurs when a person breathes in high levels of cadmium from the air, or eats food or drinks water containing high levels of cadmium. reduced buffering capacity for acids (Jarup 2002). To review relevant content, see Renal Effects in this section. 2020 Nov 8;9(11):1512. doi: 10.3390/plants9111512. In humans given radioactive cadmium, the average amount absorbed is 5% (Flanagan et al., 1978). However, selenium (Se) at low doses and incorporated into enzymes and proteins has antioxidant properties and protects animals and humans from the risk of various diseases. Some of the earliest cases of cadmium poisoning were reported in Belgium in 1858. Cadmium (Cd) is a non-essential toxic heavy metal, an environmental toxicant, and toxic at a low concentration, and it has no known beneficial role in the human body. Cadmium nephrotoxicity may follow chronic inhalation or ingestion. 1992). Toxicol Lett. Environ. 2004) study showed that current and former smokers had higher body burdens of cadmium than non-smokers and that within smokers, the body burden of cadmium was related to lung injury related to smoking. 50 mg/m3 1991). CE Expiration Date: May 11, 2013 Further work needs to be done on this topic. Experimental models often make use of the intraperitoneal route (i.p.) Curr Med Chem. Either short-term or long-term exposure to cadmium can cause serious health problems. Cadmium toxicity may cause renal dysfunction with both tubular and glomerular damage with resultant proteinuria. However, at this time, it is not known if these early subclinical changes in kidney biomarkers associated with low levels of environmental cadmium exposure have any correlation with continued decline in renal function to clinical levels of concern (Noonan et al. @article{osti_218125, title = {Cadmium exposure: Toxicity in humans. Enhanced secretion of prostaglandin E2 may also contribute to bone resorption. severe osteoporosis and osteomalacia with simultaneous severe renal dysfunction, normochromic anemia and low blood pressure sometimes also occur (Alfven, average urinary cadmium level in these patients is 20-30 ìg/g-creatinine of cadmium in urine (Ezaki. Humans normally absorb cadmium into the body either by ingestion or inhalation Dermal exposure (uptake through the skin) is generally not regarded to be of significance (Lauwerys 1988). 1-3, p. 162. Cadmium (Cd) is a toxic non-essential transition metal that poses a health risk for both humans and animals. -, Carocci A., Catalano A., Lauria G., Sinicropi M.S., Genchi G. Lead Toxicity, antioxidant defense and environment. 2010 Sep 15;198(1):49-55. doi: 10.1016/j.toxlet.2010.04.013. However, recent studies (Navas-Acien et al. 5,6 Intrarenal cadmium concentration increases over time until it reaches a cellular threshold associated with progressive renal cell injury. Toxic impacts are discussed and appear to be proportional to body burden of cadmium. Epub 2010 Apr 22. Recent studies show that cadmium induces various epigenetic changes in mammalian cells, both in vivo and in vitro, causing pathogenic risks and the development of various types of cancers. [1] There is a very low margin of safety between reaching the critical renal concentration and body burdens found in smokers (Satarug and Moore 2004). In animals, cadmium crosses the placenta, and large parenteral doses during early gestation cause birth defects. 2002). [1] Cadmium retention is generally higher in women rather than men [8]. Most cases of cadmium toxicity are due to chronic exposure. (2010) also documented apoptosis in human liver cells due to Cd intoxication. Gender differences in susceptibility, at lower exposure, are uncertain, but some data indicate that Cd has estrogenic effects and affects female offspring [8]. 2004). Zhang X, Zhou C, Li W, Li J, Wu W, Tao J, Liu H. Front Cell Dev Biol. doi: 10.1007/s00204-010-0544-6. Recently, investigations of the capability of sunflower (Helianthus annuus L.), Indian mustard (Brassica juncea), and river red gum (Eucalyptus camaldulensis) to remove cadmium from polluted soil and water have been carried out. 2004). 12. 1-3, p. 162. Safe levels of cadmium intake to prevent renal toxicity in human subjects. The first sign of renal abnormalities occur at 2 μg/g creatinine and are microscopic tubular proteinuria – the biomarkers are β2-microglobulin, ά1-microglobulin. See this image and copyright information in PMC. Cadmium -New Aspects in Human Disease, Rice Contamination, and Cytotoxicity- is a valuable resource for scientists involved in heavy metal toxicology, botanical sciences, and regulatory sciences. 2006). Other respiratory effects of chronic occupational exposure to cadmium include chronic rhinitis, destruction of the olfactory epithelium with subsequent anosmia as well as the development of bronchitis (ATSDR 1999; Drebler 2002). Cadmium leads to the development of acute toxicity when injected into the body through the … 2010;2:329–333. Alongside the three other heavy metals – arsenic, lead and mercury – cadmium appears in … The most common metals that the human body can absorb in toxic … Epidemiological data from occ… 2004, 2005) have examined the contribution of cadmium and some other heavy metals to the development of peripheral artery disease. Would you like email updates of new search results? Concentrations increase due to soil disruption/volcanic activity and a byproduct of industrial processes. Cadmium exposure may also potentiate the development of glomerulopathy in diabetic populations (Buchet et al. Epidemiological data suggest that occupational and environmental cadmium exposure may be related to various types of cancer, including breast, lung, prostate, nasopharynx, pancreas, and kidney cancers. Public Health. Cadmium (Cd) is a toxic non-essential transition metal that poses a health risk for both humans and animals. Shah AA, Bibi F, Hussain I, Yasin NA, Akram W, Tahir MS, Ali HM, Salem MZM, Siddiqui MH, Danish S, Fahad S, Datta R. Plants (Basel). It is widely distributed in humans, the chief sources of contamination being cigarette smoke, welding, and contaminated food and beverages.
