It should be depend on your area of research. If you are doing experimental research, you should spend more time in lab. But in case of computational work, you can run the computation and go back to home and see the result later as it takes time.
This depends on the area and particular experiment a person who is working. For some experiments, the results should be monitored and observed in the laboratory in a schedule may be through out the day also. Strictly there is no restriction. If a candidate is interested one can continue to do. This depends wholly on individual interest.
A PhD research is very demanding and I recommend that students should spend much time in the lab to get results, I suggest a minimum of 10-12 hours per day.
I believe it is not a function of how long one spends in the lab but how well the time is utilized. This is measured by the results or outcomes of the set objectives. However, devoting not less than 5 hours daily for PhD research work is enough.
Interesting question I agree with those how sad is not a function of how long one spends in the lab, but how well the time is utilized. But the question to have a good PhD and good results at the end, we should spend use time and well utilized, in order to have lots of good results, So at the end, we should, when we are preparing the PhD, the majority of our time working on the PhD, Success for all the PhD students, and please work more and more to have better results, in order to increase knowledge to our society
It depends of your topics and the methods you are using. Som times the laboratory staff can do all tests without researchers, while in other tests, observation is needed to understand the test results. In my department, the PhD-students are always involved in the tests.

There is no particular time to work in environmental engineering lab or any laboratory.Once any person registered for Ph.D., this person should be in lab to know in general the experiments. When coming to environmental engineering the list of experiments will be more and some of them may take even several hours.
I think your methodology and timeline should inform how much time you need to be in the lab. If your thesis is experiment intensive then you would obviously spend more time conducting those experiments (assuming you intend to complete it in "time").
The time to submit Ph.D. thesis in our University is 2 years for full time and 3 years for part time. A person may extend the time, if not completed. When coming to lab, the experiments should complete in time, hence one has to work seriously day and night to get results. Some experiments take continuous time and requires monitoring and some may not.
As much time as is required to get the job done. If that's 2 or 12 hours a days so be it. Stop measuring your (or your PhD candidates) success or failure by "how much time I see them in the lab/office" and rather judge them on the quality of their work and dissertations.
I think working too long in the lab will lead to fatigue, tiredness and may lead to poor results. Working short time for a long period will turnout quality results
Establishing a time for research in the laboratory is always difficult for any advisor. The excitement of research must always be in the foreground. Objectively and thinking about human well-being, 4 to 6 hours of work are adequate, even because it also has parallel studies to explain the experiments. From 6 to 12 months at this pace the student will have a great deal of experimental information. From the junction of experiments and scientific reading will achieve a good doctoral thesis in any technological area.
The lab for a scientist is a platform for finding answers to vital questions related to his/her field of study. Therefore, there is no specific time limit. There are those who spend most of their time in the lab because the joy of discovery and finding overrides all other proclivities in life.
I think there is no certain hours for that, if you are studying kinetic effect on the removal process of any kind of pollutant, then you need to stay for long time in the lab; otherwise normal working hours is enough
For doing Ph.D. in environmental engineering or any Ph.D., laboratory will be there and the scholars sit there only. Scholars in general will be starting work from evening. The work is not time dependent. Experimental or theoretical work should be done systematically and there should be no hurry. One day it will be completed earlier and next day it may take longer time. Hence day to day research is not time bound.
As far as our curriculum is concerned how much motivated you are for your doctoral thesis is not mandatory to the academicians . As most of the time a student involved with research work remain in a stage of inconvenience, job insecurity and many other related factors. In my preview a 180 days experimentation and then analysis is sufficient to finish Ph.D. degree.
A perfect PhD thesis must represent a novel and origin idea, solution for a unsolved-problem, formula, even ends up to several high impact paper or a good book. Therefore, many time need to accomplish an excellent PhD thesis. However, as far as I am concerned, working for any particular hours in the lab is not obligatory, as it all depends on the motivation of the PhD student.
In my opinion it depends on the nature of the research and the focus of the student. PhD research is intensive and therefore spending 10-15 hours in the lab must be okay.
Working hours in the laboratory may be flexible depending on the objectives of the research work. It may vary from 8 hours to even 18 hours depending on the need and experimental.
In my opinion it depend upon the nature of research work, If there is more technical work which included in his/her thesis it may be taken more time as compared the work which is not technical. PhD research at least 10-16hrs
