Astellas meets all legal requirements and has voluntarily drafted guidelines in line with the Soil Contamination Countermeasures Law. Astellas conducts soil contamination investigations at sites where projects such as the destruction of old facilities and the building of new ones are being undertaken, as well as at its athletic grounds and parks. These same guidelines are applied in environmentrelated decision-making for the purchase of land. In addition, regular groundwater and soil analyses are conducted and continuous monitoring is performed at facilities that handle harmful chemical substances.

In 2007, a voluntary investigation conforming to the guidance on investigation based on an Osaka Prefecture ordinance was conducted as a part of the construction work for the redevelopment of the old factory site of Kashima R&D Center. As a result, substances such as benzene, mercury, lead, arsenic and fluorine in soil, and benzene, lead, arsenic and fluorine in groundwater were detected in amounts above acceptable norms. There are no ordinary residences in the contaminated area, and the ground has been covered with asphalt and concrete.
Thus, there is no detrimental effect on the health of employees and others living in the vicinity. However, we will implement countermeasures, effectively incorporating the advice of local government authorities.

In the past three years, soil contamination investigations were conducted at the Kiyosu Research Office, Takahagi Facilities, Miyukigaoka Research Center, Yaizu Facilities and Tokodai Research Center on the occasions of facility dismantling, land purchase and the creation of athletic grounds. Results confirmed that no contamination existed.
