“…An excessive amount of this heavy metal may cause serious problems [5]. These heavy metals can be of great concern to biological organisms since they can react with many chemicals essential for biological processes [6]. Plants absorb the Pb through their roots.…”

The sanitary landfill located in Carmona, Cavite, Philippines operated from April 30, 1993, to March 31, 1998, is now closed and abandoned. Abandoning sanitary landfill without proper remediation and rehabilitation efforts pose risks to both humans and the environment. At present, only grasses and shrubs thrive in the area, and no rehabilitation efforts were made in this area. The closed landfill is nonfunctional except to the nearby inhabitants who use the abundant vegetation for grazing of animals such as cows, goats, and chicken. The possibility of heavy metal accumulation in the area is expected but is yet to determine. Likewise, its utilization into productive use remains a question. Hence, this study was conducted to investigate the existing land use, extent of lead (Pb) contamination in the soil and the grazing food chain of the area and, recommend the most practical and appropriate use of the place. Understanding the dangers it can bring to nearby communities can be used as a reference for putting forward plans and policies to protect people's welfare. Although the soil has an average of 1.36 ppm that is within the standard set by the US EPA, the level of Pb observed in plants, insects and chicken's liver are unsafe as compared to the Tolerable Daily Intake (TDI) for Pb set by the US FDA. The soil can be converted into non-play areas such as a recreational park, but the planting of edible crops and fruit-bearing trees is not recommended.

“…While the background values of Pb content in Platanus orientalis, Robinia pseudoacacia and Ulmus minor leaves amounted 2,700 ppb, it was determined that Pb content increased to 15,700 ppb in areas with heavy traffic and up to 18,800 ppb at Gisha bridge (Abbasi et al 2017). Another study pointed out that the Pb concentration in the leaves of Ficus religiosa increased up to 14,100 ppb, and the correlation analysis pursued by the authors revealed a robust correlation between traffic density and Pb accumulation in plants (Agrahari et al 2018). In many studies it has been confirmed that Pb concentration increases depending on traffic density (Al-Shidi et al 2020, Juwah and Tachere 2021, Soba et al 2021.…”

Global population growth and increasing urban population density together are responsible for many disruptions such as environmental pollution, especially air one. Trace metals are of specific prominence as air pollutants because they are conservative pollutants. They tend to accumulate biologically; some have poisonous or carcinogenic effects, even at small concentrations. Among toxic trace metals, lead (Pb) and zinc (Zn) can be harmful to human health in certain quantities. These trace metals were included in primary pollutant lists of the Agency for Toxic Substances and Disease Registry. Therefore, determining these trace metal concentrations in the air and monitoring the differences is very important for determining the risky districts and the level of risk. Biomonitors are the most important indicators of differences in trace metal concentrations in the atmosphere. The plants chosen as biomonitors intake several of the trace metals from the soil and/or the air into their bodies and determining the level of this accumulation might provide insight into the trace metal pollution of the atmosphere and soil. The present study aims to determine the variations of Pb and Zn concentrations in various landscaping plants growing in different districts of Kastamonu (Türkiye) depending on tree species, organs and traffic density. It was found that unwashed leaves of Acer negundo L. can be suggested as a good biomonitor for the presence of both analysed trace metals.

“…Medidas que possam prevenir a liberação de Pb na atmosfera são essenciais, visto que a utilização de automóveis não para de crescer. Uma alternativa é a LRP denominada de gasolina de reposição de Pb, que não contém Pb em sua composição (AGRAHARI et al, 2018). É possível notar que há uma diferença no grau de poluentes atmosféricos entre áreas residenciais e industriais, sendo essa última a que mais apresenta poluentes e efeitos nas plantas.…”

Metais pesados compreendem uma classe de metais com densidade superior a 5g/cm3 que em concentrações mínimas exercem funções importantes para os seres vivos, porém, quando em altas concentrações se tornam tóxicos para os organismos e para o meio ambiente. A liberação destes metais pesados na natureza está frequentemente relacionada a ações antropogênicas, como nas indústrias, na agricultura e nas atividades de mineração. Portanto, o monitoramento destes poluentes é de grande importância, a fim de evitar danos ao meio ambiente e aos seres vivos. A utilização de organismos ou comunidades de organismos como bioindicadores é um método de monitoramento ambiental bastante vantajoso, visto que há a possibilidade de avaliação dos impactos ao longo do tempo, as análises não são tendenciosas e apresentam resultados confiáveis. Diante disso, este trabalho teve como objetivo compilar artigos dos últimos 20 anos sobre organismos utilizados como bioindicadores da contaminação por metais pesados no meio ambiente. Dentre estes organismos destacaram-se as plantas, mamíferos, microrganismos, aves, peixes e insetos com notório potencial bioindicador de uma ampla gama de metais pesados. Diante da dinâmica ambiental, a obtenção de diferentes dados de bioindicadores para o monitoramento de um local se torna necessária para a obtenção de resultados mais precisos e rápidos.
