“…Several studies have observed the substantial impact of different substrates on the composition and contents of various elements in the fruiting bodies of mushrooms (Kalac, 2013; Hoa et al ., 2015; Siwulski et al ., 2019; Gwenzi et al ., 2021). Likewise, this study observed considerable variations in the composition and concentrations of various elements in the fruiting bodies of P. ostreatus cultivated on different substrates.…”

The use of agro-industrial waste as substrates for mushroom cultivation is considered a promising management strategy for reducing and valorising these wastes, simultaneously reducing the cost of mushroom cultivation. In this study, oyster mushroom Pleurotus ostreatus were cultivated on twelve substrates composed of either tea waste, lime sawdust, alder sawdust, hornbeam sawdust/shaving, wheat stalk-straw, wheat bran or their composite to determine the proximate composition and accumulation of thirteen elements in their fruiting bodies. The proximate composition of P. ostreatus did not show a significant difference, regardless of the employed substrate. (one-way MANOVA; F (66, 107) = 1.329, Wilk's λ = 0.041, P > 0.05). However, their chemical element contents show a statistically significant difference (one-way MANOVA; F (132, 418) = 32.163, Wilk's λ = 0.000, P < 0.05). These results were supported by discriminant function and principal component analyses. The highest mean concentrations of six of twelve elements (i.e., Ca, Mg, Na, Zn, Cd and Cr) were recorded in P. ostreatus cultivated on the lime-sawdust substrate. Three health indices viz., estimated daily intake, target hazard quotient (THQ) and total THQ were applied to determine the risk to human health via the consumption of P. ostreatus, suggesting that they are safe for human consumption.

“…Despite the lack of long-term monitoring studies in Africa, an increasing number of investigations also reported PTEs in mushrooms from various countries, including Cameroon, Ethiopia, Ghana, Nigeria, South Africa, Zambia, and Zimbabwe (Abulude & Ndamitso, 2018;Chungu et al, 2019;Gebrelibanos et al, 2016;Nharingo et al, 2015;Quarcoo, 2013;Rasalanavho et al, 2019). Gwenzi et al (2021) noticed that human exposure to toxicity occurs mainly through the consumption of mushrooms and their products and, to a lesser extent, indirectly through the ingestion of edible insects and wild animals that feed on mushrooms. In Africa, the greatest risk of human exposure to mushroom toxicity may be due to (1) the widespread consumption of mushrooms from various ferrous and highly mineralized substrates such as streamers and mine dumps, (2) inadequate and poorly enforced environmental health and food safety regulations and policies, (3) lack of environmental and human health monitoring data and well-equipped health facilities to facilitate early detection and treatment of human health effects, (4) potential synergistic interactions between PTEs in mushrooms and other human food products and health stressors, such as a high burden of human disease and infections (Gwenzi et al, 2021).…”

Ethnomycological prospect of wild edible and medicinal mushrooms from Central and Southern Africa—A review

In several regions of Africa, the daily diet is partly dependent on the edible products from wild animals, plants, and mushrooms, driven by their availability, wide distribution in the local environment, and the low incomes of the general population. The documentation of ethnomycological information is particularly important to validate or correct the identification of specimens and the preservation of these natural resources with cultivation potential, thus improving their consumption and utilization for medicinal purposes. The number of wild edible mushroom species consumed varies between different regions of Africa, with around 300 species being documented in the literature. However, despite its rich biodiversity, the African continent is still underexploited, which is reflected in poor food contribution to populations that are often in need. Here, the safe use of mushrooms is guided by the insufficiency of studies that validate their nutritional and medicinal properties, since they are key factors in the suppression of protein deficiency in the everyday diet of the populations and a source of bioactive compounds useful for the formulation of added‐value functional products. Thus, it becomes essential to investigate African mushrooms, not only from the identification point of view, but also in terms of nutritional, chemical, and bioactive characterization, hence deepen the knowledge about this valuable natural resource. Bearing these in mind, the main objective of this study is to systematize the knowledge available in scientific publications and specialized websites, thus gathering information about the valuable profits that come from using these widely appreciated natural products.

“…In many places all over the world, mushrooms may threaten human health when they are growing in polluted soils. Therefore, understanding the occurrence, fate, and behaviour of pollutants like potentially toxic elements in soil-growing mushrooms-human nexus is crucial for mitigating and assessing their risks to human health (Gwenzi et al 2021). Recently, enormous literatures from several countries have been published on the risks of edible mushrooms containing toxic pollutants for human health as reported in Poland (Siwulski et al 2020;Mleczek et al 2021;Ronda et al 2022), China (Wang et al 2021Ernst et al 2022), Iran (Dowlati et al 2021Karami et al 2021), Turkey (Keskin et al 2021a, b), and Spain (Melgar and García 2021).…”

Further studies, which take these variables into account, will need to be undertaken.…”

Edible mushrooms are considered an important source for human nutrition nowadays because of their high contents of bioactive compounds (e.g., vitamins, proteins, terpenoids, phenolic compounds, lipids, and polysaccharides). These active ingredients are also a crucial source for many industries particularly in the pharmaceutical and therapeutic fields as well as functional foods. This manuscript focuses on what we called mushrooms and their nutritional importance as well as the therapeutic applications of edible mushrooms. The possible risks of edible mushrooms for human health were also discussed; especially for those grown on polluted soils, representing a serious potential threat for human health. The harvested edible mushrooms obtained from such polluted areas may have highcontents of potentially toxic elements and other contaminants, which can threaten the human health causing several diseases.The sustainable solutions for producing safe edible mushrooms for human nutrition under different growth conditions are of interest global issue due to edible mushrooms being established as one of the most important sources of human foods.
