NEW YORK: Be­sides res­pi­ra­tory in­fec­tions, reg­u­lar ex­po­sure to air pol­lu­tion, es­pe­cially the sooty black ma­te­rial emit­ted from gas and diesel en­gines, may also in­crease the risk of bone frac­tures, finds a study.The study is sig­nif­i­cant as Delhi and Na­tional Cap­i­tal Re­gion con­tinue to wit­ness bad air qual­ity for sev­eral days in a row. Os­teo­poro­sis, the most com­mon rea­son for a bro­ken bone in­jury among the el­derly, is a dis­ease in which bones be­come brit­tle and weak as the body loses more bone mass than it can re­build. The find­ings, de­tailed in the jour­nal Lancet Plan­e­tary Health, showed that par­tic­i­pants ex­posed to higher lev­els of PM2.5 and black car­bon showed lower lev­els of parathy­roid hor­mone.
