“…Investigations have shown that human beings are largely exposed to PCBs during food ingestion, and seldom, via occupation. Thus, they can bind tightly and be deposited into fatty tissues, organs, and glands [38] , [39] . PCBs are also known suppressors of immune system function, increase the risk of diabetes, causes cardiovascular diseases, decreased verbal learning, increased depression, hypo-reflexia, neurobehavioral disturbances, reproductive disorders, etc.…”

The impact of COVID-19 on food security can best be understood from the downturn on agricultural and other related economic activities which were almost brought to a total halt during the pandemic. The restriction of movement/lockdown policy instituted by various governments heavily affected local and national food production as farmers could not go to their farmlands. More so, there was price gouging on raw food items as local farmers were reducing cultivation and harvest because of their safety. The lockdown also affected the transportation of food products from farms and local companies to the market and across inter-state/province borders. Additionally, many human infections traceable to disease outbreak from animal origin suggest a great risk of exposure to infectious agents by live animal farmers. In combating this menace, local food production needs to be encouraged more, while measures should be put in place to facilitate farmer's participation in government regulations on enforcing biosecurity, health standards, disease monitoring, and surveillance practices.

“…In fresh artificial soil samples, HXD and PHE extractability were significantly diminished as organic matter content increased, decreasing from 96 to 65% for HXD and from 99 to 80% for PHE (P < 0.05). Ti et al (2018) observed similar behavior for polychlorinated biphenyls, where an increase in soil organic matter and a decrease in soil particle size favored and strengthen adsorption, restricting mass transfer rates of these organic pollutants. In contrast, no significant differences were found in the extractability of the different organic matter content in aged samples for either HXD or PHE (P < 0.05).…”

“…Including metal bioaccessibility in soil risk assessment and monitoring strategies has increased in the last few years in relation to human health protection [101]. The influence of aging on bioaccessibility has been well documented for organic contaminants [105], while several aspects of the aging trend of the bioaccessible fractions of metals in soil over time still needs to be still clarified. The speciation of cadmium in soil largely regulates its dissolution in the gastrointestinal system which is also promoted by the low pH in the stomach.…”

Effect of Soil Aging on Cadmium Bioavailability and Bioaccessibility at a Contaminated Site

The effect of aging on cadmium (Cd) bioavailability and bioaccessibility was investigated in naturally aged field soil within a contaminated site. The results, which are based on a comparison of investigations carried out in 2018 and 2022 on the same soil samples, provide a realistic evaluation of the variation in Cd chemical forms due to long-term aging. The data obtained show a significant reduction (from approximately 30% to 60%) in the mobile and bioavailable forms of cadmium, while the total quantity in soil did not change significantly. The effect of aging on the bioavailable fractions is also reflected in the reduction in the amount of the metal absorbed by plants. On the one hand, this indicates a reduction in the potential contamination of the food chain, while on the other, it highlights the limitations of the use of phytoextraction as a clean-up technology in this specific site. In the case under study, it should also be noted that there was no decrease in cadmium bioaccessibility over time, which remained very high even after four years of cadmium aging in the soil, which was about 60% of the total content in the most contaminated soil samples. This highlights the potential health risks related to the incidental ingestion of Cd-contaminated soil, which could become the main exposure route in the case of the final use of the site as a park or public green area.
