Low-dimensional organic–inorganic metal halide hybrids (OIMHs) with an ultrabroad-band emission are promising as downconversion phosphors for solid-state lighting. However, toxicity of Pb and low photoluminescence quantum efficiency (PLQE) hamper their application. Herein, two zero-dimensional (0D) lead-free organic antimony …

If your local authority has replaced its lead water pipes with pipes made from antimony, it's highly likely that your water will contain antimony. Antimony that leaches from metal pipes is in the less toxic form of the antimony(V) oxo-anion, but you probably still don't want to drink elevated levels of this metal in your water.
