“…Saeed el al [145] determined total water soluble phthalates from plastic water bottles on glassy carbon electrode (GCE) by square wave voltammetry (SWV). They optimized some parameters such as supporting electrolyte (0.05M tetrabutylammonium bromide (TBABr)), stirring rate 1400 rpm, deposition time 20s, scan rate 0.9 Vs -1 , frequency 100 Hz and pH 4.0.…”

Phthalates are endocrine disruptors frequently occurring in the general and industrial environment and in many industrial products. Moreover, they are also suspected of being carcinogenic, teratogenic, and mutagenic, and they show diverse toxicity profiles depending on their structures. The European Union and the United States Environmental Protection Agency (US EPA) have included many phthalates in the list of priority substances with potential endocrine-disrupting action. They are: dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), butylbenzyl phthalate (BBP), diethylhexyl phthalate (DEHP), di-iso-nonyl phthalate (DINP), di-iso-decyl phthalate (DIDP), di-n-decyl phthalate (DnDP), and dioctyl phthalate (DOP). There is an ever-increasing demand for new analytical methods suitable for monitoring different phthalates in various environmental, biological, and other matrices. Separation and spectrometric methods are most frequently used. However, modern electroanalytical methods can also play a useful role in this field because of their high sensitivity, reasonable selectivity, easy automation, and miniaturization, and especially low investment and running costs, which makes them suitable for large-scale monitoring. Therefore, this review outlines possibilities and limitations of various analytical methods for determination of endocrine-disruptor phthalate esters in various matrices, including somewhat neglected electroanalytical methods.

“…94,96 In general, as the relative molecular mass of PAEs increases, the chain lengths gradually increase, structures gradually exhibit greater stability, solubility in water gradually decreases, polarities gradually decrease, and volatilization in food during the cooking process gradually decreases. 113 Thus, the migration ability gradually decreases. 114 However, a study found a high concentration of migrated DEHP, which could be explained by the fact that long-chain PAEs, such as DEHP, are weakly bound to packaging materials and thus migrate easily when heated.…”

“…The literature suggests that the migration process could be influenced by properties such as the molecular structure, relative molecular mass, and polarity of the migrating species. Studies have found that DBP and DINP have the greatest migration potential in mineral water, DEHP and DBP have the greatest migration potential in edible oil, DBP and DEHP exhibit large transfer potentials in both edible oil and mineral water, and DMP, DINP, and diisodecyl phthalate (DIDP) exhibit a lower migration. , In general, as the relative molecular mass of PAEs increases, the chain lengths gradually increase, structures gradually exhibit greater stability, solubility in water gradually decreases, polarities gradually decrease, and volatilization in food during the cooking process gradually decreases . Thus, the migration ability gradually decreases .…”

Phthalate esters (PAEs), which are commonly used as plasticizers in food processing and packaging, are common pollutants. Dietary intake is the primary route to human exposure to PAEs. Data show that retail packaged and cooked foods are most likely to be contaminated with PAEs, indicating that the food preparation and cooking processes may contribute to the migration and transformation of PAEs in food. In this review, we collected the latest investigations on the occurrence of PAEs in different food categories, discussed the mechanisms of the fate of PAEs during cooking, and summarized the reduction measures of PAEs in food. Foods such as water and beverages, meat, condiments, and baby foods are linked to PAE exposure. Many cooking techniques and procedures, including steaming, boiling, microwave heating, toasting, frying, and packaging, are responsible for the occurrence, migration, and transformation of PAEs in foods. The occurrence, transformation, and migration of PAEs in food are influenced by a variety of factors, including food categories, the cooking process, packaging materials, and physicochemical properties of PAEs. There are several ways to prevent or reduce PAEs in food, including the selection of safe packaging materials, proper food categories, cooking methods, and replacement of PAEs.

Phthalate esters (PAEs) are mainly used as plasticizers, and their release in the environment during the manufacturing, use, and disposal has caused serious environmental health concerns, since some of them are suspected to be mutagens, hepatotoxic agents, and carcinogens. In the present study, leaching of PAEs from different drinking stuffs (water cooler, mineral water bottles) exposed to sunlight and baby feeders subjected to different heating treatments (boiling, autoclave and oven) was studied. Results showed that a total of 10 PAEs were leached and identified. Among them, dimethyl phthalate, bis(2-methoxyethyl) phthalate, diethyl phthalate, and dibutyl phthalate were the major leached PAEs found in the range 9-112.50 μg L. Boiling treatment was found safer for baby feeders as PAE leaching was ~26-54% less as compared to other two treatments. The leached PAEs in water samples were then subjected to biodegradation experiment with Bacillus thuringiensis strain at optimized conditions (time 72 h and 30 °C). Hence, leaching of hazardous PAEs from different water stuffs is alarming and needs immediate attention. Moreover, B. thuringiensis strain was found effective for PAE remediation (75-96% degradation) at neutral pH. Graphical abstract ᅟ.
