“…La investigación revela que los hidrocarburos aromáticos policíclicos (HAP) están contaminando fuertemente las aguas subterráneas y los sedimentos. Se observa una dispersión de HAP en los sedimentos, y se identifican riesgos cancerígenos para la salud humana, especialmente en adultos y mediante el contacto dérmico (Lu et al, 2024) Según Qadeer et al (2024) la comparación entre éteres de difenilo polibromados (PBDE) y ésteres organofosforados (OPE) destaca similitudes en sus propiedades físicoquímicas, comportamientos ambientales y concentraciones globales. A pesar de su prohibición como contaminantes orgánicos persistentes, los OPE han aumentado, incluso superando a los PBDE en regiones prístinas.…”

Persistent organic pollutants (POPs) represent a significant environmental problem due to their toxicity, with a high capacity to persist in the environment, resistance to conventional degradation methods, the ability to accumulate in living organisms and their magnification in food chains or food. In this review article, the impacts on health and environmental components are examined. Strategies and measures for control, mitigation and/or minimization of POPs are also addressed. Agricultural and industrial activities, inadequate final disposal of solid waste and lack of wastewater treatment are identified as the main sources of POP emissions. In addition, innovative and promising technologies are analyzed, such as nanotechnology, bioremediation, rhizoremediation, biochar, chromatography techniques, ultrasound, among others, for the adequate treatment of POPs. The review highlights both the advantages and limitations of these technologies, pointing out areas that still require developments to achieve effective treatments. More economical and ecological alternatives are also mentioned to counteract the impacts of POPs.

“…At present, many researchers have conducted toxicological and epidemiological studies on OPEs. Abdul Qadeer [ 37 ] conducted a comparative analysis of PBDEs and OPEs, focusing on their persistence, bioaccumulation, and toxicity (PBT) characteristics across different domains. Striking similarities and overlap between PBDEs and OPEs in terms of their physical and chemical properties, environmental behavior, and global concentrations were unveiled by the research findings.…”

Organophosphate esters (OPEs) are frequently used as flame retardants and plasticizers in various commercial products. While initially considered as substitutes for brominated flame retardants, they have faced restrictions in some countries due to their toxic effects on organisms. We collected 37 soil and crop samples in 20 cities along the coast of South China, and OPEs were detected in all of them. Meanwhile, we studied the contamination and potential human health risks of OPEs. In soil samples, the combined concentrations of eight OPEs varied between 74.7 and 410 ng/g, averaging at 255 ng/g. Meanwhile, in plant samples, the collective concentrations of eight OPEs ranged from 202 to 751 ng/g, with an average concentration of 381 ng/g. TDCIPP, TCPP, TCEP, and ToCP were the main OPE compounds in both plant and soil samples. Within the study area, the contaminants showed different spatial distributions. Notably, higher OPEs were found in coastal agricultural soils in Guangdong Province and crops in the Guangxi Zhuang Autonomous Region. The results of an ecological risk assessment show that the farmland soil along the southern coast of China is at high or medium ecological risk. The average non-carcinogenic risk and the carcinogenic risk of OPEs in soil through ingestion and dermal exposure routes are within acceptable levels. Meanwhile, this study found that the dietary intake of OPEs through food is relatively low, but twice as high as other studies, requiring serious attention. The research findings suggest that the human risk assessment indicates potential adverse effects on human health due to OPEs in the soil–plant system along the coast of South China. This study provides a crucial foundation for managing safety risks in agricultural operations involving OPEs.
