Phthalate acid esters (PAEs) are commonly used plastic additives, not chemically bound to the that migrate into surrounding environments, posing a threat environmental and human health. Dibutyl phthalate (DBP) di(2-ethylhexyl) (DEHP) two common PAEs found in agricultural soils, where degradation is attributed microbial decomposition. Yet impact of matrix on PAE rates poorly understood. Using 14C-labelled DBP DEHP we show migration from soil represents key rate limiting step their bioavailability subsequent degradation. Incorporating film decreased soil, 79% 21% (9% <1%), over four months when compared direct application PAEs. Mimicking surface conditions, demonstrated exposure ultraviolet radiation accelerated mineralisation twofold. Turnover was promoted by addition biosolids, while presence plants other organic residues failed promote We conclude persist for longer than previously thought due physical trapping within matrix, suggesting released plastics very long time periods lead increasing levels contamination.

Phthalates in the environment of China: A scoping review of distribution, anthropogenic impact, and degradation based on meta-analysis

Ecotoxicology and Environmental Safety, Journal Year: 2025, Volume and Issue: 289, P. 117659 - 117659

Published: Jan. 1, 2025

Phthalates (PAEs) are a group of endocrine-disrupting environmental chemicals (EEDs) that pose significant risks to human health. PAEs widespread in various media, including air, dust, water, and soil, subject both horizontal vertical migration. Human activities significantly influence the distribution PAEs, yet current research on this relationship remains limited. In study, we first describe hot issues environment through bibliometrics, then review published related studies. We outline global different media conducted comparative analysis their composition. Principal component (PCA) revealed differences mediums geographic locations. Correlation between composition China further demonstrated PAE concentrations were closely linked agricultural industrial activities. also discussed biodegradation abiotic degradation finding bacteria play crucial role soil. This study aims assess distribution, transfer, impact, providing insights for prevention remediation pollution.

Organophosphate Flame Retardants in Pregnant Women: Sources, Occurrence, and Potential Risks to Pregnancy Outcomes

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(18), P. 7109 - 7128

Published: April 20, 2023

Organophosphate flame retardants (OPFRs) are found in various environmental matrixes and human samples. Exposure to OPFRs during gestation may interfere with pregnancy, for example, inducing maternal oxidative stress hypertension interfering fetal thyroid hormone secretion neurodevelopment, causing metabolic abnormalities. However, the consequences of OPFR exposure on pregnant women, impact mother-to-child transmission OPFRs, harmful effects pregnancy outcomes have not been evaluated. This review describes women worldwide, based metabolites (mOPs) urine prenatal breast milk postnatal exposure. Predictors variability mOPs discussed. Mother-to-child pathways scrutinized, considering levels their amniotic fluid, placenta, deciduae, chorionic villi, cord blood. The results showed that bis(1,3-dichloro-2-propyl) phosphate (BDCIPP) diphenyl (DPHP) were two predominant urine, detection frequencies >90%. estimated daily intake (EDIM) indicates low risk when infants exposed from milk. Furthermore, higher increase adverse influence developmental behavior infants. summarizes knowledge gaps highlights crucial steps assessing health risks susceptible populations, such as fetuses.

Nontarget Identification of Novel Organophosphorus Flame Retardants and Plasticizers in Rainfall Runoffs and Agricultural Soils around a Plastic Recycling Industrial Park

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(34), P. 12794 - 12805

Published: Aug. 14, 2023

Plastic recycling and reprocessing activities may release organophosphate ester (OPE) flame retardants plasticizers into the surrounding environment. However, relevant contamination profiles impacts remain not well studied. This study investigated occurrence of 28 OPEs their metabolites (mOPEs) in rainfall runoffs agricultural soils around one largest plastic industrial parks North China identified novel organophosphorus compounds (NOPs) using high-resolution mass spectrometry-based nontarget analysis. Twenty twenty-seven were detected runoff water soil samples, with total concentrations 86.0–2491 ng/L 2.53–199 ng/g dw, respectively. Thirteen NOPs identified, which eight reported environment for first time, including a chlorine-containing OPE, an heterocycle, phosphite, three OPE metabolites, two oligomers. Triphenylphosphine oxide diphenylphosphinic acid occurred ubiquitously soils, up to 390 40.2 The downwind areas park showed elevated levels NOPs. contribution hydroxylated mOPEs was higher than runoffs. These findings suggest that are significant sources biotransformation further increase ecological human exposure risk.
