We analyze experimental data of nuclear structure function ratios
F2A/F2D for obtaining optimum parton distribution functions
(PDFs) in nuclei. Then, uncertainties of the nuclear PDFs are
estimated by the Hessian method. Parametrization of nuclear parton
distribution is investigated in the leading order of αs.
The parton distribution are provided at Q2=1 GeV2 with a
number of parameters, which are determined by a χ2 analysis
of the data on nuclear structure function.
From the analysis, we propose parton distributions at Q2=1GeV2 for nuclei from deuteron to heavy ones with a mass number
A ∼ 208.
