In 1972, the first coastal zone management law in the world was approved in the United States. Fifty years later, its influence on other national and international legislation is clear, but how this law has influenced the scientific community is not yet determined. Through a scientometric analysis based on the Web of Science and Scopus databases, over 11,340 bibliographic references were consolidated and refined to extract those directly related to legal aspects of coastal management. A final set of 135 scientific documents published between the years 1974 and 2022 were analyzed with the tool Core of Science®. As a result, the Tree of Science was obtained, which identifies the precursory (roots), axis (trunk), and promising (leaves) documents related to coastal regulation. Another output was a compilation of the scientific production over the last 50 years as documented in both databases, allowing us to extract the countries, journals, and authors who were most productive in advancing research on the legal issues of ICZM. Moreover, co-authorship networks were identified based on the most active geographical regions and authors. In the end, a brief reflection is provided about the influence that a legal instrument can have on the scientific community and vice versa. • Scientometric analysis was performed on 11,340 references related to ICZM and law. • The influence on the scientific community by the world's first ICZM law is determined. • The stronger influence of the CZMA in English-speaking countries is confirmed. • CZMA's influence started in the U.S., but it became worldwide in the XXI century.

Abstract: A simple electroanalytical method using square wave voltammetry at a Pt band ultramicroelectrode to perform a qualitative and quantitative analysis of different synthetic antioxidant mixtures permitted by official regulations in edible oils is proposed. The methodology was based on the comparison of voltammetric signals obtained in acetonitrile+0.1M (C4H9)4NF6P with those recorded in the same reaction medium when different aliquots of (C4H9)4NOH were added to allow a qualitative differentiation between antioxidants. Firstly, studies on solutions prepared from commercial reagents were carried out. Then, the results obtained were transferred to the analysis of a real matrix, i.e., an edible olive oil. From real samples spiked with a known amount of different synthetic antioxidant mixtures, we could deduce the presence of these antioxidants by comparing results obtained in the neutral medium with those obtained after the successive addition of base. The standard addition method was used to quantify the individually spiked synthetic antioxidants in the real sample. Recovery percentages were between 88% and 118%. The reproducibility was 1.5%, 3.1%, 4.1% and 4.1% in ACN+0.1M TBAHFP and 1.5%, 4.6%, 6.6% and 2.5% in Bz/EtOH (1:2)+0.1M H2SO4 for TBHQ, BHA, BHT and PG, respectively. The repeatability was 1% for PG in both media. These parameters show a good system performance. [Copyright &y& Elsevier]

• A novel electroanalytical method was developed to determine CAR in OEO samples. • Second-order cyclic voltammetry data were generated varying the scan rate. • The CAR determination was performed in presence of thymol as a potential interferent. • MCR-ALS was successfully used to obtain the second order advantage. A novel analytical method using voltammetric second-order modeling based on multivariate curve resolution-alternating least-square (MCR-ALS) is presented for the first time for the quantitation of carvacrol (CAR) in oregano essential oils (OEO). The second-order cyclic voltammetry data were generated on the basis that CAR shows a diffusional system. Thus, the scan rate (v) was used as a second instrumental mode and cyclic voltammograms at different v were acquired for a single sample, generating the second-order data. CAR determination was performed in presence of thymol, included as a potential interferent. Results demonstrated that MCR-ALS successfully exploited the second-order advantage and the recoveries were not statistically different than 100%. The limits of detection and quantitation were estimated using the MCR-ALS which were 6.27 × 10−5°mol°L−1°and 1.90 × 10−4°mol L−1, respectively. Finally, the developed methodology was implemented to quantify of CAR in OEO samples. [ABSTRACT FROM AUTHOR]
