enterprises, the city constantly experiences environmental problems. At the end of the 1970s, Zhdanov (Mariupol) ranked third in the USSR (after Novokuznetsk and Magnitogorsk) in the quantity of industrial emissions. In 1989, including all enterprises, the city had 5,215 sources of atmospheric pollution producing 752,900 tons of harmful substances a year (about 98% from metallurgical enterprises and Mariupol Coke-Chemical Plant "Markokhim"). Even given some easing of the maximum permissible concentrations (maximum concentration limit) in the state's industrial activity in the mid-1990s, many pollution limits were still exceeded: 1.3 times for ammonia 1.3 times for phenol 2.0 times for formaldehyde In the residential areas adjoining the industrial giants, concentrations of benzapiren reach 6–9 times the maximum concentration limits; fluoric hydrogen, ammonia, and formaldehyde reach 2–3 to 5 times the maximum concentration limits; dust and oxides of carbon, and hydrogen sulphide are 6–8 times the maximum concentration limits; and dioxides of nitrogen are 2–3 times the maximum concentration limits. The maximum concentration limit has been exceed on phenol by 17x, and on benzapiren by 13-14x. Ill-considered locations of the Azovstal and Markokhim to economize on transport charges, during both construction in the 1930s and subsequent operations, have led to extensive wind-borne emissions into the central areas of Mariupol. Wind intensity and geographical "flatness" offer relief from the accumulation of long-standing pollutants, somewhat easing the problem. The nearby Sea of Azov is in distress. The fish catch in the area has been reduced by orders of magnitude over the last 30–40 years. The environmental protection activity of the leading industrial enterprises in Mariupol costs millions of hrivnas, but it appears to have little effect on the city's long-standing environmental problems. Governance City administration and local politics The Mariupol electorate traditionally supports left wing (socialist and communist) and pro-Russian political parties. At the turn of the 21st century the Party of Regions numerically prevailed in the City Council followed by the Socialist Party of Ukraine. In the presidential elections of 2004, 91.1% of the city voted for Viktor Yanukovych and 5.93% for Viktor Yuschenko. In the 2006 parliamentary elections, the city voted for the Party of Regions with 39.72% of the votes, the Socialist Party of Ukraine with 20.38%, the Natalia Vitrenko Block with 9.53%, and the Communist Party of Ukraine with 3.29%. In the 2014 parliamentary elections the Opposition Bloc won more than 50% of the votes. The seats of the city's two
