From there, they pass through wastewater treatment plants into surface waters. Even though it has been established that only a small percentage of APIs present in the wastewaters are generated by the manufacturing process (the major part results from the final users of pharmaceutical products), ecotoxicity data of APIs are regularly reviewed and evaluated, and proper action is taken. 2.8.1 Odor At all the sites, we have installed biofilters wherever odor from industrial process is expected, thus preventing it from affecting the local population (e.g. above wastewater equa- lization ponds). The monitoring of biofilters' operation and waste air loads is carried out by the Public Health Institute Maribor. Slovenia's environmental regulations do not cover environmental odor pollution. In 2012, we received a letter from the civil initiative / Lendava community, complaining about an unpleasant odor occasio- nally spreading from the public sewer pipeline duct bordering the Lek facility. As the duct is an integral part of the municipal sanitary wastewater system, the odor is the result of insuffici- ent flow rate within the duct, particularly in summer. 2.8.2 Soil As the environmental impact on soil pollution is usually irre- versible, this area is of special concern to Lek. We consistently fulfill the requirements for hazardous sub- stance storage and transport, which are the major soil pol- lutants. We regularly check the leak tightness of sewage sy- stems, particularly those carrying industrial wastewater. This is of particular importance at the Menge‰ and Ljubljana sites which are situated in a water protection area. Furthermore, we introduce preventive measures in the production proces- ses and the construction of facilities. To date, no remedial action due to soil pollution has been needed at Lek. 2.8 Other environmental impacts Table 19: Land use by site 55 Menge‰ Lendava Prevalje Ljubljana Lek Green surfaces (in m 2 ) 45,748 104,478 28,780 6,698 185,704 Building surfaces – aerial view (in m 2 ) 32,145 12,963 38,003 6,658 89,769 Asphalt surface – roads, courtyards (in m 2 ) 39,023 19,222 43,315 5,171 106,731 Total site surface area with parking lots (in m 2 ) 126,537 136,663 121,015 18,527 402,742 Production site surface area/product (in m 2 /t) 231.5 623.5 29.2 18.1 67.9
