We examine an asymptotic behavior at zero of distributions and densities of a sum of several independent positive random variables under certain assumptions on the decay rate of their distributions at zero. We consider the cases, when the distributions (densities) of summable random variables are regularly or slowly varying at zero or can decrease at zero with an arbitrary rate.
