“…Soil-based HFG may pose a contamination risk due to urban soil, besides, low fertility, low organic matter, decreased activity and diversity of soil organisms, as well as high concentrations of stones, gravels, and artifacts are frequently found in urban soils. These elements may have a detrimental effect on horticultural crop productivity, rendering urban soils unsuitable for HFG, therefore, utilizing inert and clean substrates is an effective solution (Ercilla-Montserrat et al, 2018;Izquierdo-Díaz et al, 2023). Spanish researchers found that the output of a open-air rooftop soilless home food garden based on perlite bag culture, can achieve a high degree of self-provisioning for a two-member household (Boneta et al, 2019).…”

“…These contaminants have the potential to accumulate in the human body when consuming food grown in polluted soils, leading to various side effects, including carcinogenic risks (Gao et al, 2015;Manucharova et al, 2021;Nematollahi et al, 2022;Zhu et al, 2023;Lange et al, 2024). While food contamination from polluted urban soil can be addressed through the adoption of substrate culture or hydroponics, it is important to note that toxic heavy metals present in the atmosphere of densely populated areas may pose a threat to the safety of home-grown food (Izquierdo-Díaz et al, 2023). Fortunately, theses toxic heavy metal particles primarily adhering to the leaf surface and that their absorption into the plant tissue is limited.…”

“…Fortunately, theses toxic heavy metal particles primarily adhering to the leaf surface and that their absorption into the plant tissue is limited. Consequently, it is strongly advised to wash vegetables produced in urban gardens in order to minimize the possibility of ingesting toxins that may be adhered to surfaces (Izquierdo-Díaz et al, 2023).…”

Against the backdrop of the unexpected COVID-19 epidemic, governments are facing significant challenges in mobilizing food resources, particularly fresh products. It is inevitable that there will be intermittent shortages of food during the pandemic. As a result, home food gardening has gained considerable attention from city residents and policymakers in modern cities. This is due to its potential to provide food during humanitarian emergencies and lockdown. Moreover, home food gardening is increasingly becoming a popular recreational activity in many countries, offering therapeutic benefits such as fostering social bonds through knowledge-sharing and fruit-sharing, improving mental and psychological well-being, promoting outdoor physical exercise, and strengthening the connection between humans and nature. This review provides a comprehensive summary of the latest advancements in home food gardening, including cultivated species, devices, technologies, and current issues. It also proposes perspectives based on current researches to serve as a reference for future research and development.

Air pollution, long recognized as having an adverse impact on health and comfort, is increasing in urban and industrial areas of society at a rate that makes it one of the most pressing environmental problems. Pollution refers to the introduction of harmful substances into the environment, negatively impacting humans and other organisms and contributing to the degradation of the quality of our environment. This paper aims to discuss the identification of certain plant species that can be used as biological indicators in assessing air quality. In this context, the aim of this paper is to analyze several theoretical aspects of biological monitoring and provide a report on the progress of using plants as biological indicators of air quality. This paper aims to describe the most significant aspects of current knowledge in this field, evaluate the applicability of the methodology, and detail its advantages and disadvantages when compared with traditional methods.

“…Urban areas have a substantial impact on air quality at all levels (Folberth et al, 2015). Airborne particles from anthropogenic sources usually transport trace elements (such as HM), salts (sulphates and nitrates) and organic compounds adsorbed on their surface (Izquierdo-Díaz et al, 2023). Due to their ability to associate with air masses, HM are recirculated by winds, depositing in areas far from their origin, either on the ground or on plants in urban and peri-urban areas (Imperato et al 2003;Ferreira et al, 2018a).…”

The growth in urbanization and industrialization is causing an increase in environmental pollution in cities and their surrounding areas. Additionally, the growing urban population requires a greater volume of fresh vegetables. In nature, heavy metals (HM) are widely distributed; when they gradually enter the soil-plant-consumer continuum, they are difficult to remove from the system and accumulate at toxic levels. To gain an overview of this situation, the information in the ScienceDirect database was used in accordance with the PRISMA guide. For this, the keywords “vegetable”, “contamination” and “urban” were used in a first step and, in a second step, the keywords “vegetable” and “heavy metal” were used. The most toxic HM for consumers are Cd, Pb, Hg, Cr and As, as well as essential MP for the plant (Zn, Cu, Ni, Fe, Mo). At excessive concentrations these cause neurological and kidney damage, cancer and other forms of damage to health. Crop contamination can come from the atmosphere, irrigation water, and/or the soil itself, proximity to busy roads, industry, polluted rivers, and excessive use of pesticides and fertilizers that contain HM. Plant poisoning by HM causes a decrease in root growth and biomass of the plant, foliar chlorosis, and other physiological alterations. Leafy vegetables (including aromatic herbs) and solanaceous vegetables accumulate the most HM, while cucurbits and legumes are the least affected. Plants that develop for a longer time accumulate a greater amount of HM. In general, to increase the food safety of urban horticulture, more studies are needed on HM contamination, soil aptitude, risk assessment for ingesting intoxicated vegetables, as well as appropriate instructions for the clean handling of these crops in cities and surrounding areas.
