| Submission declined on 23 July 2024 by Timtrent (talk). This submission's references do not show that the subject qualifies for a Wikipedia article—that is, they do not show significant coverage (not just passing mentions) about the subject in published, reliable, secondary sources that are independent of the subject (see the guidelines on the notability of people). Before any resubmission, additional references meeting these criteria should be added (see technical help and learn about mistakes to avoid when addressing this issue). If no additional references exist, the subject is not suitable for Wikipedia. This submission is not adequately supported by reliable sources.

Comment: I have cut much of the remaining puffery for you. More can go when you find it. Please follow my example 🇺🇦 FiddleTimtrent FaddleTalk to me 🇺🇦 12:18, 26 July 2024 (UTC)
- Comment: When given advice to cut out the paean of praise, please understand that advice is given to assist you in getting your draft accepted. You are free to ignore the advice, but I predict further reviewers will also decline for similar reasons.Repeated "half a job" resubmissions tend to result in eventual rejection of a draft. Please do all the work, not some of it. 🇺🇦 FiddleTimtrent FaddleTalk to me 🇺🇦 19:26, 23 July 2024 (UTC)
- Comment: You have written a paean of praise, not an Wikipedia article, and you have omitted citations from important sections. This is a good start. Please attend to the tone, and to the referencing. 🇺🇦 FiddleTimtrent FaddleTalk to me 🇺🇦 18:53, 23 July 2024 (UTC)
Shamitha Kusum Perera is a Sri Lankan scientist specializing in chemistry, drug design, and public health. He completed his secondary education at Royal College Colombo and earned his B.Sc. (Hons) in Chemistry from the University of Colombo in 1974. He obtained his Ph.D. in Drug Design and Development from the State University of New York in 1978, focusing on steroids and prostaglandins. Perera also furthered his studies at the University of California, Davis School of Medicine.
Perera began his career as the first Quality Assurance Officer at the Environmental Chemistry Laboratory, where he ensured data quality standards[1]. He later moved to the Drinking Water and Radiation Laboratory, contributing to the implementation of national drinking water standards[2][3].
His research primarily focuses on developing analytical methods for detecting environmental contaminants and toxins. Notable work includes his study on the trace-level detection of 1,4-dioxane in water using isotopic dilution GC and GC-MS, improving sensitivity for this carcinogen[4].[5] He developed multiresidue HPLC methods for phenyl urea herbicides, enhancing agricultural chemical monitoring[5]. Perera also optimized receptor binding assays for paralytic shellfish poisoning toxins as an alternative to traditional methods[6].
Perera has contributed to the understanding of radioactive contamination in water, studying isotopes such as 210Pb and 210Po in California groundwater[7]. He advanced techniques in atmospheric pressure ionization mass spectrometry, identifying unknown toxic compounds like urushiol congeners[8]. His research comparing receptor binding assays to mouse bioassays for shellfish toxins provided valuable insights for regulatory applications[9].
Perera has published 26 research papers, and his work significantly impacts environmental protection and public health[10][11].
