“…Akibatnya, Sr-90 dapat tersimpan di jaringan berkalsium, seperti tulang. Selain itu, Y-90 sebagai hasil peluruhan beta dari Sr-90 menghasilkan partikel beta energi tinggi yang meningkatkan risiko kanker tulang [1]. Studi pada tikus juga menunjukkan bahwa paparan radiasi internal dari Sr-90 dapat mengganggu siklus asam trikarboksilat yang merupakan jalur utama produksi energi [2].…”

Kontaminasi permukaan daerah kerja pada Laboratorium Kimia PDPL (Pemantauan Dosis Personel dan Lingkungan) memiliki pengaruh terhadap keselamatan pekerja secara langsung maupun tidak langsung. Pada analisis uji in vitro terdapat kemungkinan masuknya zat radioaktif akibat kontaminasi ketika proses pengambilan uranium dan Sr-90 dari penyimpanan sumber, kegiatan preparasi, dan saat proses pelimbahan. Penelitian ini bertujuan sebagai upaya proteksi dan keselamatan radiasi terhadap pekerja dari kontaminasi pada saat melakukan kegiatan analisis uji in vitro di laboratorium kimia PDPL. Pengukuran menggunakan surveimeter didapatkan tingkat kontaminasi tertinggi mencapai 0,03 Bq/cm2 pada botol sumber Sr-90. Dari hasil perhitungan tingkat kontaminasi permukaan di botol penyimpanan sumber dan di hotplate pemanasan larutan spike (larutan yang terdapat sumber uranium dan Sr-90) diperoleh hasil bahwa pada daerah pengawasan tidak memerlukan tindakan proteksi atau keselamatan khusus, yaitu rata-rata tingkat kontaminasi permukaan pada daerah kerja tergolong rendah (<3,7 Bq/cm2). Tingkat kontaminasi dapat disebabkan karena aktivitas penggunaan radioisotop setiap harinya berbeda-beda. Dosis yang diterima pekerja pada saat melimbahkan limbah padat, cair, dan saat di ruang sumber dikategorikan aman karena tidak melebihi Nilai Batas Dosis (NBD) yang ditentukan, yaitu sebesar 3 μSv/jam.

“…Although the green chemistry approach is not new, the use of green chemistry metrics, especially for assessing analytical procedures, is still a big challenge (Tobiszewski, 2016; Tobiszewski et al, 2015). Green metrics tools mainly include (1) the National Environmental Methods Index (NEMI) pictograms (Bigus et al, 2016; (the oldest tool, qualitative nature; Tobiszewski et al, 2015); (2) the Eco Scale table score (Bigus et al, 2016), which encompasses information about the kind and amount of chemicals used, the energy used in the process, occupational hazards, and the amount of waste generated; and (3) the high‐performance liquid chromatography environmental assay tool (HPLC‐EAT; Gaber et al, 2011; Rivera‐Silva et al, 2019), which measures any impacts on the analyst safety/health and the environment. However, because none of those tools can solely take into consideration all 12 principles of green chemistry (Bigus et al, 2016; Gaber et al, 2011; Tobiszewski, 2016; Tobiszewski et al, 2015), it is advisable to merge them into a single parameter, to determine the environmental performance of analytical procedures.…”

In the present study, a method for the determination of residues of the neonicotinoid insecticides thiamethoxam and imidacloprid in the stingless bee Melipona scutellaris Latreille (1811) was optimized through a factorial design, tested using green metrics, and then applied to exposed bees. It combines the extraction with a modified quick, easy, cheap, effective, rugged, and safe method and the determination by liquid chromatography–tandem mass spectrometry analysis. Different parameters such as the mass of the sample, dispersive sorbents, and elution solvents were assessed. Method validation parameters were checked and include sensitivity, specificity, and linearity. The limit of quantification of 0.0025 μg g–1 was obtained for both insecticides, where accuracy was 94%–100% with satisfactory intraday and interday precisions (relative standard deviation <10%). The qualified method was applied to orally and topically exposed bee samples, and the results indicated that it is suitable for the determination and quantification of neonicotinoid pesticide residues in this species. Moreover, green analytical metrics like the National Environmental Methods Index, Eco Scale score, high‐performance liquid chromatography with an environmental assessment tool (HPLC‐EAT), waste generation, and amount of sample were compared with methods described in the literature involving neonicotinoid analysis in honeybees. As a result, the present study displayed the highest Eco Scale score and HPLC‐EAT score and the second smallest amount of sample and waste generated. Thus, the method meets green analytical metrics more than other methods. In this sense, besides the application, the multicriteria decision analysis tool employed suggests that this is a good option as a green analytical method.

“…Sr activity concentration was determined by measuring its daughter 90 Y in secular equilibrium (Rivera-Silva et al, 2019). Samples were dried and ashed at 610ºC to remove 9 organic materials, and then 1 to 3 g of ashes were used for the analysis.…”
