what's in rio's bay and beaches? - national geographic

Roughly 16 million people live around the bay, making it one of the world’s most densely populated urban areas. Many neighborhoods lack proper sanitation, causing squalid water conditions, including raw sewage and extreme levels of disease-causing microorganisms in Guanabara Bay. Athletes have complained the water is littered with trash, and that it irritates their skin and causes stomach ailments. Some teams have instructed Olympic rowers to avoid splashing water on each other and to carry hand sanitizer onboard their boats

These water pollution problems aren’t unique. According to the United Nations, up to 90 percent of wastewater in developing countries flows untreated into waterways used for bathing, drinking, or fishing

A lot of the pollution comes from raw sewage. Roughly half of the houses in the Guanabara Bay drainage basin—Rio de Janeiro and the surrounding cities—remain unconnected to sewage treatment plants. That means waste from millions of people flows untreated into the bay. Experts say the percentages of households without a sewage system may be much higher in slums and shantytowns where some houses have no access at all to toilets or tap water. Sewage overflows worsen during the rainy season from October to April, when rainfall can overwhelm the sewers that carry waste to sewage treatment plants

Urban runoff and industrial wastewater also are major sources of pollution. About 17,000 industries surround Guanabara Bay, including pharmaceuticals, refineries, and oil and gas terminals. Every day an estimated 150 metric tons of industrial wastewater flows into the bay—enough to fill about 7 large tanker trucks

Human sewage can carry a number of pathogens, including viruses and bacteria. Enteric viruses—excreted in feces and found at high levels in untreated sewage—are a major concern in Guanabara Bay, says Kristina Mena, an associate professor at the University of Texas Health Science Center at Houston School of Public Health. She studies water quality and human health risk, and independently reviewed a 2015 Associated Press study that found extreme levels of an enteric virus called adenovirus in Guanabara Bay

Located at the mouth of Guanabara Bay, Copacabana Beach, where the marathon swimmers and triathalon athletes will compete, generally has better water quality than the bay. But some antibiotic-resistant bacteria have turned up in high levels at Rio’s beaches. A strain of “super-bacteria” called carbapenemase-producing bacteria (CPB) was detected at five beaches, including Copacabana

Renata Picão, an environmental microbiologist at the Federal University of Rio de Janeiro, says her study is the first to find CPB—usually associated with hospital waste—in recreational waters. While infection can spell trouble for hospital patients with compromised immune systems, “we have no idea about the risks outside of the hospital environment,” says Picão

That’s hard to know, says Mena. Not everyone exposed to waterborne pathogens—which can enter the body through the nose, eyes, mouth, or even cuts on the body—will become infected. And not everyone who becomes infected will get sick, she says

Several athletes fell ill while training in Rio, including 13 U.S. rowers at a test event last summer. Last week Belgian sailor Evi Van Acker, who won a bronze medal at the London Olympics, said she became sick with stomach problems after sailing on Rio's bay. Yet it’s impossible to know whether these gastrointestinal illnesses were the result of Guanabara Bay exposures

Nevertheless, the viral counts in Guanabara Bay are some of the worst Mena has ever seen. “This is such an extreme situation both in the range of microorganisms present and the extent of exposure. There are going to be health risks,” she says

Waterborne illnesses are a major problem for Rio residents, especially Rio’s poorest people who live near the most polluted parts of the bay and have the least access to sanitation, says Ricardo Igreja, an infectious disease doctor at the Federal University of Rio de Janeiro

Eating seafood contaminated with heavy metals, industrial chemicals including PCBs, and hydrocarbons from petroleum products, also causes long-term health concern for Rio residents practicing subsistence fishing in Guanabara Bay, says Abílio Soares Gomes, a marine biologist at the Federal Fluminense University in Niterói, a Rio suburb

Historical records show that thousands of fish, dolphins, and whales once swam in Guanabara Bay. “If you look back 100 maybe 150 years, there were so many fish that people would say hitting them was a problem for boats,” says Fabiano Thompson, an oceanographer at the Federal University of Rio de Janeiro

Numbers of marine mammals have dwindled over the last couple decades. A small population of gray Guiana dolphins remains in the bay. Their bodies contain high levels of heavy metals, including mercury and other industrial chemicals. The possible effects on the dolphins remain unknown, though some of these chemicals have been linked to altered hormones and problems with the immune system in marine mammals

An influx of nutrients caused by sewage and urban runoff can lead to excessive plant and algae growth in parts of the bay. Sometimes the algae use up too much oxygen in the water, causing fish to die. A string of oil spills in Guanabara Bay over the past two decades also have led to massive fish kills

Brazil, like most countries, has federal laws with standards to govern water quality. But the standards set in Brazil are “more permissive” than in the United States or Europe, says Picão. For instance, an E.coli count of up to 800 is acceptable in Brazil, whereas European standards typically set E.coli counts below 500, she says. E.coli is a bacterial indicator of fecal contamination

Rio de Janeiro is a state in the United States of Brazil; capital of the state and capital of the Republic until 1960 (when the capital was transferred to Brasilia); area of the state: 43.696 km2; population: 14,391,282 (2000); population of the city: 6,094,183 (2005); estimated Jewish population: 30,000 (2020)

New Christians from Portugal immigrated to Rio de Janeiro from the 16th to the 18th centuries, and they played a significant role in the city’s social and economic life. The Inquisition accused and prosecuted more than 300 New Christians in the city’s region for practicing Judaism. With the proclamation of the independent Brazilian empire (1822) and the promulgation of the Constitution (1824), which espoused relative religious tolerance, some individual European Jewish dealers and immigrants began to appear in Rio de Janeiro, which was the capital and one of the most important harbors of the country. One of the prominent individuals among these first newcomers was Denis de Samuel (1782–1860), a young immigrant from England who gained great success and influence and earned the title of baron from the king of Portugal. Another prominent dealer who had business in Rio de Janeiro was Bernard Wallerstein

The first attempt at communal organization was made in 1840–50 by Jews originating from Morocco who went to Rio de Janeiro from northern Brazil. The organization União Shel Guemilut Ḥassadim, which still exists, ascribes its origin to this attempt. In 1867, a council of the Alliance Israélite Universelle was established in the city. In 1873, Sociedade União Israelita do Brazil, a society for religious and welfare matters was registered; it continued its activities until 1893. Another institution of the imperial period was Sociedade Israelita do Rito Português (Jewish Society of the Portuguese Rite)

At the time of proclamation of the Republic (1889) the number of Jews in Rio de Janeiro was estimated at 200. In 1900, there were two synagogues, one formed by North African immigrants and the other by West European immigrants. In 1900, a new wave of Jewish immigration began, and by the end of World War I the city’s Jewish population was estimated at 2,000

A great wave of Jewish immigration to Rio de Janeiro occurred after World War I, and as the Jewish community grew, communal life became more diversified. The Jewish community established a well-organized institutional life and reached successful economic, social, and cultural integration into local culture and society

In 1910, the Centro Israelita do Rio de Janeiro was founded; its principal objective was the establishment of a synagogue and a cemetery. The latter was founded in 1920 in Vila Rosali. The first philanthropic institution was established under the name Achiezer in 1912; its name was changed later (1920) to Sociedade Beneficente Israelita e Amparo aos Imigrantes (Hilfs-Ferein-Relief). The “Relief” was linked to ICA, HIAS, and Emigdirect, and in 1942 founded a Departamento de Seguro Mútuo Social (Department of Mutual Social Insurance), which in fact was a credit cooperative

Other social institutions founded were: Sociedade das Damas Israelitas (Jewish Women’s Association–Froein Farein, 1923); Lar da Criança Israelita (Jewish Children’s Home, 1923); Policlínica Israelita (1937, that later became a hospital); and Lar da Velhice (Old Age Home, 1963), created by Sociedade das Damas Israelitas). Jewish women prostitutes founded in Rio de Janeiro the Associação Beneficente Funerária e Religiosa Israelita (Beneficent, Funeral, and Religious Jewish Association) that functioned from 1906 to 1968

During World War II the Jewish community was active and founded the Comitê Hebreu-Brasileiro para as Vítimas da Guerra (Jewish Brazilian Committee for War Victims) and the Comitê de Socorro aos Israelitas Vítimas de Guerra (Aid Committee for Jewish War Victims). The writer Stefan Zweig immigrated to Brazil in 1936, joined the Jewish community, and wrote a famous book about the country: Brasil, país do futuro. His suicide in 1942 (together with his wife, Lotte), in the countryside city of Petrópolis, was a notable event in the life of the Jewish community and Brazilian history

The community had its social and cultural center in the Praça Onze, close to the downtown area and the port, where an atmosphere of “Yiddishkeit” was present in daily life until the 1950s, when the Jews moved to other neighborhoods. The writer and Zionist leader Samuel Malamud is the main narrator of the memories from Praça Onze and of Jewish life in Rio de Janeiro. In Praça Onze, also the center of the local Carnaval and a cultural and social meeting point for black people, almost 3,000 Jews frequented the socialist club Cabiras, the parties of the Azul e Branco Club, and other local non-Jewish institutions

The Zionist movement and the socialist groups were both very active in Rio de Janeiro. The First Zionist Congress in Brazil took place in 1922 with the participation of four different movements, including Tiferet Sion (1919). In 1921, a Brazilian delegate took part in the 12th Zionist Congress in Karlsbad. In 1929, a Brazilian delegate to the 16th Zionist Congress was elected by 1,260 votes. In 1934, the elections drew 2,647 voters. In 1927 the Central Committee of the Po’alei Zion Party was founded and later the Grêmio Hebreu-Brasileiro (Hebrew-Brazilian League)

Many Jewish leftist movements and parties were very active in Rio de Janeiro, among them socialists, communists, and the Bund, in the Biblioteca Israelita Brasileira Scholem Aleichem (Jewish Brazilian Sholem Aleichem Library, 1915), Colégio Israelita Brasileiro Scholem Aleichem (Jewish Brazilian Sholem Aleichem School, 1928), Sociedade Brasileira Pró-Colonização Judaica na União Soviética–Brazkor (Brazilian Society for the Jewish Colonization in the Soviet Union, 1928), and Centro Operário Morris Vinchevsky (Morris Vinchevsky Labor Center, 1928). The last two organizations founded a workers’ school (Arbeter Shule) and edited the newspaper Der Onheib. Other leftist organizations were the União Cultural Israelita Brasileira Ikuf, Clube dos Cabiras (1941–50), the Associação Feminina Israelita Brasileira Vita Kempner, and the Associação Kinderland. In 2005, the Associação Scholem Aleichem (ASA) was an active political and cultural center and edited the Boletim da ASA, the sole Jewish leftist publication in Portuguese

The Yiddish press was very active in Rio de Janeiro with the publication of a few newspapers: Dos Yidishe Vochenblat, Yidishe Presse, and Brazilianer Yidishe Tzaytung. Other important publications in Portuguese were the weekly magazine Aonde Vamos? and O Reflexo. Adolfo Aizen was a Brazilian pioneer of comics

Niterói has had an organized Jewish community since 1916. Its activities include religious services, with a synagogue and a cemetery, and it maintains a local school and organizes cultural and social activities. Petrópolis is a resort city for the residents of Rio de Janeiro. Its community is small, but it nevertheless established a yeshivah to train rabbinical students. In Nilópolis, situated on the route of the central railway of Brazil, a Jewish community was organized in the 1920s with a Centro Israelita (1936), the Sh. An-Ski complementary school, a synagogue, the Macabi club, Wizo, and a Yiddish theater group. In 1947, when Nilópolis became a city, there were 300 families, but later all the members moved to other cities. In Campos, the Sociedade União Israelita de Campos was established in 1929 by 40–50 families
