Most of the time PhD studentships are advertised with a small grant (called a stipend) which covers university fees, laboratory fees and provides a reasonable amount of money for your living costs. There are usually lots of applicants for each PhD studentship, so it’s worth making an effort with your application form, and also reading up on the subject of the PhD. if you get invited to an interview.
For those seeking specialist training in environmental or ecotoxicology, diplomas in subjects such as pollution science, pesticide science or waste management are also available.
