I'm writing about a type of smokeless tobacco used in asia (nicotiana rustica linn), my purpose is to find out about heavy metals such Cd, Ni, Zn, Cu and etc in nicotiana rustica linn.
This is a wonderful topic that will definitely add to knowledge in the Academic world. However, the methodology for this study cannot be determined without furnishing us with some information such as when this product (the smokeless tobacco) was introduced in the country/when the consumption started in your country. This will guide if the study should be a case control (depending on how rich your data is) or cohort study. This must be known to guide the study.
You should also put into consideration the timeline, for if the study is a requirement for a degree, you should bear in mind that you cannot therefore adopt a method that requires long timeline. Hope this will guide you in making a decision.
Adekunle Adeleke, thank you for your good advice. nicotiana rustica linn is one of our most popular smokeless tobacco products and is widely used in the southeast of Turkey. there are many studies that have been made about how it affects health and economy. but still no studies on major heavy metal in nicotiana rustica linn have been presented. to the community. I am preparing this research for postgraduate degree purpose, so I wanted to share it publicly in order to gain knowledge, skills and academic success.
