Environmental pollutants and contaminants adulterate food and drinking water through various routes from farm to plate and pose serious threats to human health, according to a study published in the Journal of Toxicology.
Some of these occur naturally in the environment (plant toxins), while others are artificially induced by humans (whether intentional or accidental). The different phases of food processing, packaging, transportation and storage are also significant contributors to food contamination. (Related: 4 most dangerous toxins deliberately and secretly infused into our food supply.)
Here are some hazardous adulterants or impurities and their health implications:
Persistent organic pollutants (POPs) are chemicals of global concern due to their potential for long-range transport, persistence in the environment, ability to bio-magnify and bio-accumulate in ecosystems, as well as their significant negative effects on human health and the environment.
Due to their stability and low decomposition rates, they persist in the environment – resisting degradation or breakdown through natural, physical, chemical or biological processes. They can be transported over long distances through the air and ocean currents. They are pervasive and can accumulate in unhealthy quantities in humans and animals.

The most commonly encountered POPs are:
An article in Everyday Health identified the common causes of heavy metal poisoning. They are industrial exposure; air or water pollution; foods and medicines; improperly coated food containers, plates and cookware; and ingestion of lead-based paints, insecticides, herbicides and inorganic fertilizers and pesticides. (Related: Food-borne poisons: Diet changes can reduce contamination risk.)
The following metals are the ones most tested for:
Researchers have noted that while the risk of potential toxicity due to natural plant toxins is very low, there is always the possibility of undetected contamination in some individuals or adverse effects that develop unpredictably in susceptible individuals.
Examples of natural plant toxins are lectins and ricin.
Lectins are glycoproteins present in leguminous plants like kidney beans, soybeans, lentils, black beans and other grains. Also called hemagglutinins, lectins agglutinate red blood cells and also interfere with nutrient absorption by the intestine.
Ricin, on the other hand, is a natural, highly potent toxin that is a byproduct of processing castor beans to make castor oil. If inhaled, injected or ingested, less than a pinpoint of ricin can kill a person within 36 to 48 hours due to the failure of the respiratory and circulatory systems.
According to an article in Food Safety Magazine, ingestion of water contaminated with thermoplastics (plastics that soften on heating and can be molded into different shapes), thermosets (plastics that cannot be molded on heating), chemicals that improve the properties of plastic materials (fillers, plasticizers, colorants, stabilizers and processing aids) and microplastics is the main exposure route for several marine and freshwater species, as well as for humans.
A growing body of evidence points to health risks posed by plastic additives, including endocrine-disrupting chemicals, which are linked to infertility, obesity, diabetes and prostate or breast cancer. Other health conditions linked to additives include reproductive growth, cognitive impairment and neurodevelopment disorders.
According to a study published in the International Journal of Environmental Research and Public Health (IJERPH), inhalation is another microplastic entry point to the human body. Microplastics are carried by the wind or from atmospheric deposits – resulting from the erosion of agricultural and fertilized lands, dried sludges and products from wastewater treatment, synthetic clothes fabrics, industrial emissions and road dust. Depending on the differences in individual metabolism and susceptibility, the response to inhaled particles may include immediate asthma-like reactions, chronic pneumonia and chronic bronchitis.
A study published in Critical Reviews in Food Science and Nutrition showed the presence of inorganic micro- and nano-sized contaminants in 40 percent of the bread and biscuits analyzed by means of an environmental scanning electron microscopy. Researchers found that the majority of the foreign bodies (ceramic and metallic debris) were not biodegradable, some are chemically toxic and none of them have any nutritional value.
