Abstract
Perfluoroalkyl carboxylic acids (PFCAs) are emerging contaminants frequently detected in various environmental matrices, including plants. Their persistence, bioaccumulation potential, and toxicity pose substantial ecological and health risks. Despite their ubiquity, a comprehensive understanding of PFCAs behaviour in plants remains inadequate. This review systematically evaluates the sources, occurrence, and accumulation of PFCAs in plants, offering critical insights into their environmental behaviour and impacts. It outlines the distinctive physicochemical properties and bioaccumulation potential of PFCAs, and examines their environmental sources and plant uptake pathways. The occurrence of PFCAs across diverse plant species is explored, alongside the mechanisms driving their accumulation. Key factors influencing PFCAs accumulation, such as plant species, environmental conditions, and the physicochemical properties of PFCAs, are thoroughly analysed. Moreover, this review identifies key research needs, such as understanding foliar uptake and precursor transformation, strengthening urban vegetation monitoring, developing regulatory thresholds for plant contamination, and evaluating phytoremediation performance under complex environmental conditions.
期刊介绍：
Environmental Geochemistry and Health publishes original research papers and review papers across the broad field of environmental geochemistry. Environmental geochemistry and health establishes and explains links between the natural or disturbed chemical composition of the earth’s surface and the health of plants, animals and people.
Beneficial elements regulate or promote enzymatic and hormonal activity whereas other elements may be toxic. Bedrock geochemistry controls the composition of soil and hence that of water and vegetation. Environmental issues, such as pollution, arising from the extraction and use of mineral resources, are discussed. The effects of contaminants introduced into the earth’s geochemical systems are examined. Geochemical surveys of soil, water and plants show how major and trace elements are distributed geographically. Associated epidemiological studies reveal the possibility of causal links between the natural or disturbed geochemical environment and disease. Experimental research illuminates the nature or consequences of natural or disturbed geochemical processes.
The journal particularly welcomes novel research linking environmental geochemistry and health issues on such topics as: heavy metals (including mercury), persistent organic pollutants (POPs), and mixed chemicals emitted through human activities, such as uncontrolled recycling of electronic-waste; waste recycling; surface-atmospheric interaction processes (natural and anthropogenic emissions, vertical transport, deposition, and physical-chemical interaction) of gases and aerosols; phytoremediation/restoration of contaminated sites; food contamination and safety; environmental effects of medicines; effects and toxicity of mixed pollutants; speciation of heavy metals/metalloids; effects of mining; disturbed geochemistry from human behavior, natural or man-made hazards; particle and nanoparticle toxicology; risk and the vulnerability of populations, etc.
