Research by the Institut de Veille Sanitaire (IVS) found higher levels of pesticides used in agriculture, horticulture and the home, as well as Polychlorinated biphenyls (PCBs), in the French.
One pesticide in particular, paradichlorobenzene, which is used in items such as mothballs and toilet fresheners was highlighted at being at a higher level than expected.
The IVS study tested the blood, hair and urine of around 2,700 adults between 2006 and 2007 for metals, mercury, pesticides and PCBs.
