In addition, chemical pollutants can also indirectly endanger embryos and fetuses by interfering the normal functions of the placenta and caul through the matrix. Various pollutants in the air like carbon monoxide, oxynitride, cyanogen compund, vinyl chloride and polycyclic aromatic compound can restrain the normal growth of the nervous system of the fetuses and cause fetal anomaly. Among all the chemical pollutants, various kinds of metal like cadmium, mercury, copper, gallium, lead and arsenic can cause poisoning. In fact, the most common and dangerous…
