  We study quantum deformations of Poisson orbivarieties. Given a Poisson
manifold $(\mathbb{R}^{m},\alpha)$ we consider the Poisson orbivariety
$(\mathbb{R}^{m})^{n}/S_{n}$. The Kontsevich star product on functions on
$(\mathbb{R}^{m})^{n}$ induces a star product on functions on
$(\mathbb{R}^{m})^{n}/S_{n}$. We provide explicit formulae for the case
${{\mathfrak h} \times {\mathfrak h}}/\mathcal{W}$, where ${\mathfrak h}$ is
the Cartan subalgebra of a classical Lie algebra ${\mathfrak g}$ and
$\mathcal{W}$ is the Weyl group of ${\mathfrak h}$. We approach our problem
from a fairly general point of view, introducing Polya functors for categories
over non-symmetric Hopf operads.
