I am 25 week 4 days pregnant working at a gas station is there any harm in my growing fetus ?

There are risks: The risks to your "growing fetus" depend on your "working environment" and the extent and duration of your exposure to toxic fumes, gasoline vapors,gases from car /truck exhausts among others...Heavy metals particularly lead if present in fuels can be inhaled or absorbed through your skin and can be very harmful to a fetus or to an infant. Caution and a toxicology consultation may be indicated
