In October, when officials were investigating lead contamination in the water supply at several public housing estates and schools, Ng asked whether lead could be good for people’s health.
“Is there evidence suggesting that consuming water with an appropriate level of lead can strengthen one’s health and extend life?” he asked.
He speculated whether the rising longevity of Hong Kong people might have something to do with the widespread presence of lead in water.
