Hiroshima officials urged world leaders Tuesday to stop relying on nuclear weapons as deterrence and take immediate action toward abolishment — not as an ideal, but to remove the risk of atomic war amid conflicts in Ukraine and the Middle East and rising tensions in East Asia.

They commented as Hiroshima remembered its atomic bombing 79 years ago at the end of World War II.

The memorial comes days after Japan and the US reaffirmed Washington's commitment to “extended deterrence,” which includes atomic weapons, to protect its Asian ally. That is a shift from Japan’s past reluctance to openly discuss the sensitive issue as the world’s only country to have suffered atomic attacks.

Hiroshima Gov. Hidehiko Yuzaki said nuclear-armed nations and supporters of atomic deterrence “deliberately ignore ... the fact that once people invented a weapon, they used it without exception.”

“As long as nuclear weapons exist, they will surely be used again someday,” Yuzaki said in his address at the Hiroshima Peace Memorial Park.

“Nuclear weapons abolition is not an ideal to achieve far in the future. Instead, it is a pressing and real issue that we should desperately engage in at this moment since nuclear problems involve an imminent risk to human survival,” he said.

Hiroshima Mayor Kazumi Matsui said Russia’s war on Ukraine and the worsening conflict between Israel and Palestinians are “deepening distrust and fear among nations” and reinforcing a view that use of force in settling conflict is unavoidable.

The atomic bomb dropped by the United States on Hiroshima on Aug. 6, 1945, destroyed the city, killing 140,000 people. A second bomb dropped three days later on Nagasaki killed 70,000 more. Japan surrendered on Aug. 15, ending World War II and Japan’s nearly half-century aggression in Asia.

About 50,000 people at the ceremony observed a minute of silence with the sound of a peace bell at 8:15 a.m., the time when a US B-29 dropped the bomb on the city. Hundreds of white doves, considered symbols of peace, were released.

Prime Minister Fumio Kishida, who attended the ceremony, said global conflicts and divided views over approaches to nuclear disarmament make achieving that goal “all the more challenging,” but pledged to do his utmost in pursuing “realistic and practical measures” to build momentum within the international community.

His critics say it is a hollow promise because Japan relies on the US nuclear umbrella for protection and has been rapidly expanding its military.

Japan, the United States and other regional allies have been stepping up security cooperation in response to a more assertive China and the growing nuclear and missile threats from North Korea. Japan has sought stronger US protection by its nuclear capability.

Many survivors of the bombings have lasting injuries and illnesses resulting from the explosions and radiation exposure and have faced discrimination in Japan.

As of March, 106,823 survivors — 6,824 fewer than a year ago, and now with an average age of 85.58 — are certified as eligible for government medical support, according to the Health and Welfare Ministry. Many others, including those who say they were victims of the radioactive “black rain” that fell outside the initially designated areas of Hiroshima and Nagasaki, are still without support.

Hiroshima officials called on Kishida’s government to do more to provide support and address their wishes.

The aging survivors, known as “hibakusha,” continue to push for a nuclear arms ban as they desperately campaign to have their effort kept alive by younger generations.



Microplastics Are Everywhere, but Are They Harming Us?

Microplastics have been found in the ocean and the air, in our food and water. They have been found in a wide range of body tissues, including the heart, liver and kidneys.

But are they actually harming you?

Evidence suggests they might, but it's limited in scope. Some researchers are worried, but acknowledge there are lots of unanswered questions.

Dr. Marya Zlatnik, a San Francisco-based obstetrician who has studied environmental toxins and pregnancy, has seen studies raising concerns about microplastics' impact on the health of babies and adults.

But it's a young research field, and it's not something she generally discusses with patients.

"I'm not entirely sure what to say yet," Zlatnik said.

Here's a look at what's known so far:

WHAT ARE MICROPLASTICS?

Plastics are man-made materials — many of them derived from oil or other petroleum products. They can break down into smaller particles, through exposure to heat and weather and even animal digestion.

Researchers have increasingly been interested in microplastics, which can be as wide as a pencil eraser or as small as a fraction of the width of a human hair. Nanoplastics, another area of study, are even smaller.

These minuscule plastics have been detected in air, water and soil, in milk, and in bottled and tap drinking water. They also have been found in a variety of foods, including salt, sugar, honey, rice and seafood.

ARE THERE MICROPLASTICS IN YOU?

Most likely yes.

There is scientific debate about how much people inhale and ingest, and it can vary on what they eat and drink and where they live, researchers say.

Some Australian researchers, on behalf of the World Wildlife Fund, calculated in 2019 that many people each week consume roughly 5 grams of plastic from common food and beverages — the equivalent of a credit card. That estimate is not universally embraced by researchers, but is commonly mentioned in news articles.

Researchers are still trying to understand exposure levels, but study after study is finding signs of plastics in body tissues.

"Microplastics have been measured in pretty much all of the body tissues that have been evaluated," said Tracey Woodruff, a University of California at San Francisco researcher. Scientists have even reported finding them in the penis, in ovaries and in placentas.

WILL MICROPLASTICS HURT YOU?

That's still being sorted out.

A 2022 World Health Organization report concluded there was no clear risk to human health, based on the available evidence.

There’s also not an obvious signal of widespread public health impact, at least in terms of mortality. Cancer, heart disease and stroke death rates have been falling, not rising.

But researchers only started measuring plastics in the human body — and trying to assess the health effects — in recent years. Some of that work is only coming to fruition now.

It makes sense that microplastics are harmful because they contain toxic chemicals, said Woodruff, who was part of a team that reviewed nearly 2,000 studies about microplastics at the request of California legislators. It may be, for example, that microplastics play a role in rising occurrences of some cancers in younger people, she said.

Available information indicates plastics can spark inflammation and cause other problematic changes in the body that can, for example, raise the risk of heart attack and stroke.

A small study in the New England Journal of Medicine earlier this year suggested, but did not prove, that patients with evidence of plastics in their arteries were at greater risk of death from heart attacks and strokes. But an expert not involved in the research suggested the study may have overstated any effects.

"Even though there’s a lot we still don’t know about microplastic particles and the harm they cause to humans, the information that is available today is in my mind very concerning," said Dr. Philip Landrigan, of Boston College.

WHAT CAN YOU DO ABOUT MICROPLASTICS?

There are ways to reduce potential microplastics exposure, researchers say.

Take your shoes off before you go in the house, to avoid tracking in plastics-laden dust (not to mention germs, dirt and other debris) throughout your home.

Eat foods — especially fresh fruits and vegetables — that you prepare in the home.

Don’t microwave a meal in a plastic tray, no matter what TV dinner instructions might say, Woodruff said.

And opt for reusable stainless steel or glass water bottles, rather than disposable plastic ones, she added.

Zlatnik, the obstetrician, noted that families with limited incomes may have bigger things to worry about.

"If someone is worried about where their next meal is going to come from, I'm not going to give them advice to keep their leftovers in glass containers and to not microwave in plastic," she said.
