Environment
Like other former European members of the Council for Mutual Economic Assistance, Bulgaria saw unimpeded industrial growth as a vital sign of social welfare and progress toward the socialist ideal. Because this approach made environmental issues a taboo subject in socialist Bulgaria, the degree of damage by postwar industrial policy went unassessed until the government of Todor Zhivkov (1962–1989) was overthrown in late 1989. The Zhivkov government's commitment to heavy industry and lack of money to spend on protective measures forced it to conceal major environmental hazards, especially when relations with other countries were at stake. Factories that did not meet environmental standards paid symbolic fines and had no incentive to institute real environmental protection measures.
In 1991 Bulgarian environmentalists estimated that 60% of the country's agricultural land was damaged by excessive use of pesticides and fertilizers and by industrial fallout. In 1991 two thirds of Bulgarian rivers were polluted, and the Yantra River was classified as the dirtiest river in Europe. By that time, about two-thirds of the primary forests had been cut. However, despite its recognition of the need for greater environmental protection, Bulgaria budgeted only 10.4 billion leva.
Perhaps the most serious environmental problem in Bulgaria was in the Danube port city of Rousse. From 1981 to 1989, the chemical pollution that spread from a chlorine and sodium plant across the Danube in Giurgiu, Romania, was a forbidden subject in Bulgaria because it posed a threat to good relations between two Warsaw Pact countries. Chemical plants in Rousse also contributed to the pollution. Citizen environmentalists opposing the situation in Rousse organized the first demonstrations and the first independent political group to oppose the Zhivkov regime. During the Giurgiu plant's first year of operation, chlorine levels in Rousse almost doubled, reaching two times the permissible maximum in the summer of 1990. Over 3,000 families left the city in the 1980s despite government restrictions aimed at covering up the problem. Besides chlorine and its byproducts, the plant produced chemical agents for the rubber industry, and in 1991 some sources reported that the plant was processing industrial waste from Western countries—both activities likely to further damage Rousse's environment. International experts claimed that half of Rousse's pollutants came from Giurgiu, and the others came from Bulgarian industries. In response to the formidable Bulgarian environmental movement, some Bulgarian plants have been closed or have added protective measures; the Giurgiu plant, however, was planning to expand in 1991.
Pollution of agricultural land from a copper plant near the town of Srednogorie provoked harsh public criticism. The plant emitted toxic clouds containing copper, lead, and arsenic. In 1988 it released toxic wastewater into nearby rivers used to irrigate land in the Plovdiv-Pazardzhik Plain, which includes some of Bulgaria's best agricultural land. The groundwater beneath the plain also was poisoned. Work has begun on a plan to drain toxic wastewater from the plant's reservoir into the Maritsa River. Environmental improvements for the copper plant and three other factories in the Plovdiv area (a lead and zinc factory, a chemical factory, and a uranium factory) also were planned, but they would take years to implement.
None of Bulgaria's large cities escaped serious environmental pollution. Statistics showed that 70 to 80% of Sofia's air pollution is caused by emissions from cars, trucks, and buses. Temperature inversions over the city aggravated the problem. Two other major polluters, the Kremikovtzi AD Metallurgy Works and the Buhovo uranium mine (both in southwestern Bulgaria), contaminated the region with lead, sulfur dioxide, hydrogen sulfide, ethanol, and mercury. The city of Kardzhali became heavily polluted with lead from its lead and zinc complex. In 1973 the petroleum and chemical plant near the Black Sea port of Burgas released large amounts of chlorine in an incident similar to the one in Srednogorie. Environmentalists estimated that the area within a thirty-kilometer radius of the plant was rendered uninhabitable by that release. The air in Burgas was also heavily polluted with carbon and sulfur dioxide in 1990.
In 1990 environmental scientists claimed that two-thirds of Bulgaria's population suffered from the polluted environment to some degree. In 1991 Bulgaria began seeking international assistance in solving environmental problems. Besides joining Romania, Turkey, and Russia in joint scientific studies of the critically polluted Black Sea, Bulgaria actively sought environmental technology and expertise from Western Europe and the United States.

Famous quotes containing the word environment:
“Autonomy means women defining themselves and the values by which they will live, and beginning to think of institutional arrangements which will order their environment in line with their needs.... Autonomy means moving out from a world in which one is born to marginality, to a past without meaning, and a future determined by others—into a world in which one acts and chooses, aware of a meaningful past and free to shape one’s future.”
—Gerda Lerner (b. 1920)
“Maturity involves being honest and true to oneself, making decisions based on a conscious internal process, assuming responsibility for one’s decisions, having healthy relationships with others and developing one’s own true gifts. It involves thinking about one’s environment and deciding what one will and won’t accept.”
—Mary Pipher (20th century)
“For those parents from lower-class and minority communities ... [who] have had minimal experience in negotiating dominant, external institutions or have had negative and hostile contact with social service agencies, their initial approaches to the school are often overwhelming and difficult. Not only does the school feel like an alien environment with incomprehensible norms and structures, but the families often do not feel entitled to make demands or force disagreements.”
—Sara Lawrence Lightfoot (20th century)
