POISONOUS INGREDIENTS

摘要

There are over 100 polycyclic aromatic hydrocarbons (PAHs) found in oil, coal and tar, which are readily released into the environment when fossil fuels are burned. Many of them are harmful to humans and wildlife. In humans they have been shown to cause infertility by killing egg cells in the ovaries. They may also stunt the growth of fetuses by damaging their DNA.
