D. Bussan
Faculty & Executive Search Consulting,Career Coaching, Resume Writing and Toxic Metals Consultant

Whether you represent a municipality, are a concerned citizen, or conduct research, I offer expert consulting on trace and heavy metals. I have authored more than 20 peer‑reviewed publications—many focused on toxic metals—and completed a Ph.D. that centered on method development for metal analysis. If you already have laboratory results, I can review and interpret them in detail.
I also consult directly with researchers and analytical laboratories on method development and validation for inductively coupled plasma–mass spectrometry (ICP‑MS), inductively coupled plasma–optical emission spectrometry (ICP‑OES), and microwave digestion techniques. From optimizing instrument parameters and developing robust calibration strategies to troubleshooting interferences and refining sample‑prep workflows, I will help you achieve accurate, reproducible data and meet regulatory or publication‑quality standards.
Among my notable papers is “Quantification of Trace Elements in Surgical and KN95 Face Masks Widely Used During the SARS‑COVID‑19 Pandemic,” published at the pandemic’s peak. I have also examined heavy‑metal contamination in coffee products, water, and athletic mouthguards. With recent reports of lead in baby food and other consumer goods, independent evaluation has never been more critical.
My research has shown that laboratory quality can vary widely. To reduce costs, some facilities rely on undertrained technicians who operate instruments without fully understanding the methodology, often compromising data integrity. In line with the principle that you get what you pay for, I provide meticulous, evidence‑based reviews of water or product reports related to trace metals. My consulting rate starts at $150 per hour.
