Heavy metals are a group of mostly metallic elements that occur naturally in the environment but can be toxic to humans and the environment at elevated concentrations [16], [8], [12]. Exposure can occur through contaminated food, water, air, and industrial processes [8], [21], [15].
The term 'heavy metals' refers to a loosely defined group of metallic elements characterized by their high atomic weight and density [30], [16]. Common examples include lead, mercury, cadmium, arsenic, and chromium [6], [8], [16]. Although some heavy metals are essential nutrients in trace amounts, they can become toxic at higher concentrations [27].
Cadmium was discovered by Friedrich Stromeyer [18].
Historical incidents like Itai-Itai disease (related to cadmium in rice) and Minamata disease (caused by methylmercury in seafood) raised awareness of heavy metal toxicity [16].
Spectroscopic techniques facilitated the measurement of low concentrations of heavy metals, expanding research in this area [16].
The "Heavy Metals in the Environment" conference marked an early platform for expanding research [16].
The Basel Convention was signed to control transboundary movements of hazardous wastes [34].
The Minamata Convention on Mercury was signed to protect human health and the environment from mercury emissions and releases [36].
California Assembly Bill No. 899 required baby food manufacturers selling in the state to test their products for heavy metals and make those test results publicly available [43].
Exposure to heavy metals like arsenic, lead, cadmium, and copper is associated with increased risk of cardiovascular disease [6], [7].
Heavy metal exposure can be linked to obesity [5].
Heavy metals can accumulate in the body, leading to various health issues, including neurological, gastrointestinal, and renal problems [8], [15].
Environmental toxic metal contaminants and risk of cardiovascular disease: systematic review and meta-analysis
Exposure to arsenic, lead, cadmium, and copper is associated with an increased risk of cardiovascular disease and coronary heart disease [6], [7].
The association between heavy metal exposure and obesity
Lead exposure was significantly associated with a lower risk of obesity, while mercury exposure showed a positive correlation with obesity [5].
Toxic Mechanisms of Five Heavy Metals: Mercury, Lead, Chromium, Cadmium, and Arsenic
Bioaccumulation of heavy metals can lead to acute or chronic poisonings, affecting various systems in the body [8].
Generally unsafe at elevated levels; some are essential nutrients in trace amounts [27], [8].
The toxicity of heavy metals depends on factors such as the specific metal, dose, route and duration of exposure, and individual susceptibility [12].
Soft Table Foods
Offer soft table foods instead of commercial baby foods to reduce exposure to heavy metals [20].
Variety of Foods
Feed babies and children a wide variety of foods to avoid overexposure to any single source of heavy metals [25].
Organic Foods
Eating organic foods can help reduce exposure to synthetic pesticides [25].
Calcium-Rich Vegan Foods
To ensure adequate calcium intake without relying on dairy products that may contain contaminants [40].
Limit consumption of foods known to be high in heavy metals, such as rice and certain fish [20], [27].
Choose products from brands that transparently share their heavy metal testing results [43].
Test your home's water supply for lead, especially if you have old plumbing [27].
Be cautious of herbal medicines and supplements that may contain heavy metals [27].
