Exposure of smoke solutions from CNG-powered four-stroke auto-rickshaws induces distressed embryonic movements, embryonic hemorrhaging and ectopia cordis.

In south Asian countries, a campaign has launched to promote CNG-powered four-stroke auto-rickshaws (CNFAR) to decrease emission load in the environment. Even though, CNFAR are considered environmentally safe, emissions of some other toxic chemicals would amplify, which may effect the development of growing fetus and may result in different growth defects. By utilizing the in vivo chicken embryo model, this report analyzes the toxic potential of CNFAR smoke solutions (CNFARSS) on embryonic movements (EM) and cardiovascular development.
