The below-street-level New York Transit Museum Store in downtown Brooklyn takes underground standards to a new level with antique subway token cufflinks, monogrammed mosaic tiles and subway map showercurtains.
They are chemicals found in a wide array of common household products -- a list that is as long as it is familiar -- shampoos and conditioners, cosmetics, plastics, showercurtains, mattresses, electronics like computers and cell phones, among others.
