Phytoremediation, which involves using aquatic macrophytes to remove contaminants from water, is recognized as an environmentally sustainable and cost-effective remediation strategy. This study investigates the phytoremediation capacity of <i>Eichhornia crassipes</i> in reducing heavy metal contamination in the transboundary Orontes (Asi) River within Türkiye's borders. The Asi River, spanning 571 km from Lebanon through Syria to the Mediterranean Sea in Hatay, Türkiye, is severely affected by heavy metal pollution, primarily due to agricultural activities. The study assessed the bioaccumulation potential of <i>E. crassipes</i>, which grows abundantly in the river, focusing on metal accumulation in its petioles. The concentrations of cadmium, cobalt, chromium, and lead in petioles were quantified at 6.69, 23.50, 29.77, and 65.25 mg kg^-1, respectively, while the maximum concentrations of these metals in the aquatic habitat were 76.57, 303.26, 693.58, and 106.19 µg L^-1, respectively. The effectiveness of phytoremediation can be further enhanced through genetic modification, microbial stimulation, and chemical or natural amendments. These findings illustrate the significant potential of <i>E. crassipes</i> for heavy metal remediation in natural water bodies, contributing to ecosystem conservation, species sustainability, and biodiversity protection.</p>","PeriodicalId":15671,"journal":{"name":"Journal of Environmental Science and Health Part A-toxic\\/hazardous Substances & Environmental Engineering","volume":" ","pages":"1-13"},"PeriodicalIF":1.9,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144003759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Breast milk biomonitoring provides insights into human exposure levels of PAHs from increasing environmental sources, which is scantily reported in Nigeria. Twenty-eight breast milk samples were obtained from lactating mothers with written informed consent, and lifestyle data was elicited with a structured questionnaire. Eight PAH compounds were analyzed using Gas Chromatography with Flame Ionization Detector. Detected PAH levels significantly exceed the European Union maximum permissible limits for human exposure (0.001 mg/kg) in all samples. Benzo[a]pyrene (BaP) (1.07 mg/kg) was the highest, and lowest was benzo[b]naphtho[2,1-d]thiophene (BNT) (0.07 mg/kg), which was higher than the average concentrations reported in most studies globally. This may suggest substantial risks of acute and chronic health effects to vulnerable groups (lactating mothers and newborns). The carcinogenic risk assessment indicates that 60% of infants may develop carcinogenic health risks due to the ingestion of PAH-contaminated breast milk. Low birth weight, preterm birth, and fetal loss were experienced by the participating mothers.

This study explores the dual role of <i>Chlorella vulgaris</i> in bioplastic synthesis and environmental remediation through its cultivation in a wastewater-fed bioreactor. By leveraging wastewater as a nutrient source, <i>C. vulgaris</i> achieved a biomass yield of 3.472 g/L, with 20 mg/L of polyhydroxyalkanoate (PHA) extracted. Fourier Transform Infrared (FTIR) spectroscopy validated the presence of PHA-specific ester functional groups, confirming its suitability for bioplastic applications. Additionally, the cultivation process resulted in a complete reduction of free CO₂ within three days, demonstrating efficient carbon sequestration. Significant declines in wastewater contaminants, including COD, BOD, nitrogen, and phosphorus, highlight the microalga's bioremediation capabilities, making it a promising candidate for sustainable wastewater treatment. This study introduces a cost-efficient, self-sustaining microalgal bioprocess that eliminates the need for synthetic nutrients while achieving high-yield PHA production, complete CO₂ sequestration, and efficient wastewater detoxification. By integrating three essential sustainability goals- bioplastic production, carbon capture, and water purification- this work bridges the gap between bio-based materials and environmental conservation. The results affirm <i>C. vulgaris</i> as a multifunctional bioresource that supports both biopolymer synthesis and climate change mitigation.
