Angela Richardson accuses campaigners against polluted water of putting Conservative MPs in danger

The Conservative party deputy chair Angela Richardson called the sewage crisis a “political football” and claimed opposition parties and activists had put Tory MPs in physical danger by campaigning on the issue.

Richardson, who is standing for re-election in Guildford, where the River Wey was recently found to have 10 times the safe limit of E coli, also suggested the only reason people were talking about the problem was “because the Conservatives let everyone know it was happening”.

Pre-1950, we just didn’t take plastic to the beach. Now it’s virtually impossible not to, even if it’s just you and your swimmers. “If you’re looking for plastic-free nirvana, you may never find it,” says Anne-Marie Soulsby, aka the Sustainable Lifecoach. Matters are improving – though there’s usually a premium to pay if you want to minus cheap plastic from the mix. So why not borrow the plastic that already exists from friends, family or your local Library of Things. And don’t forget your reusable cutlery and containers for eating and drinking à la plage. If you can’t track down beach essentials from these sources, these are the other best ways to avoid seaside plastic pollution.

Fears of fire and environmental disaster as company repeatedly misses UK deadlines to decommission sites

The North Sea’s biggest oil and gas infrastructure company is risking fires and environmental disasters, experts have warned, as documents reveal it is failing to plug its ageing oil wells in time and is missing decommissioning deadlines by up to a decade.

Last year, the fossil fuel firm Perenco faced controversy after an oil spill from its Poole Harbour operations polluted the Dorset site, which is internationally recognised for its ecological importance. The RSPB reported oiled birds in the water at the largest natural harbour in Europe, which is one of the most heavily protected areas in the UK. Perenco promised it would never happen again and committed to pay for the damage caused.

• ‘It’s a poison and it’s killing us’: the hidden dangers of old UK landfills

Thousands of polluted landfills across England could be leaking toxic chemicals into the environment and harming people who live nearby, experts have warned.

A few decades ago, the method for getting rid of industrial and domestic waste was to stick it in a hole in the ground, cover it up and hope for the best. It was known as “dilute and disperse” and it assumed toxic substances would seep into the surrounding soils, air and water and become harmless.

Water quality testing by campaigners shows levels up to 27 times acceptable limit for bathing as rowers told to take precautions

Harmful E coli bacteria have been found at very high levels at Henley, days before elite rowers compete in the international regatta there.

Water quality testing in the Henley Mile, part of the regatta course outside the Oxfordshire town, has revealed mean levels of 1,213 E coli colony forming units (CFU) per 100ml of water, across 27 tests. Where E coli levels are above 900 CFU/100ml, the water quality is deemed poor, according to bathing water designations, and is a threat to public health.

On Tuesday, a slim majority of the US Supreme Court issued an emergency ruling that places a stay on rules developed by the Environmental Protection Agency, meant to limit the spread of ozone-generating pollutants across state lines. Because it was handled on an emergency basis, the decision was made without any evidence gathered during lower court proceedings. As a result, the justices don't even agree on the nature of the regulations the EPA has proposed, leading to a blistering dissent from Justice Amy Coney Barrett, who was joined by the court's three liberal justices.

Bad neighbors

The rule at issue arose from the EPA's regular process of revisiting existing limits in light of changes in public health information and pollution-control technology. In this case, the focus was on ozone-producing chemicals; in 2015, the EPA chose to lower the limit on ozone from 75 to 70 parts per billion.

Once these standards are set, states are required to submit plans that fulfill two purposes. One is to limit pollution within the state itself; the second involves pollution controls that will limit the exposure in states that are downwind of the pollution sources. The EPA is required to evaluate these plans; if they are deemed insufficient, the EPA can require the states to follow a federal plan devised by the EPA.

Boom in air cargo due to shoppers’ expectations of speedy delivery and shift in post-pandemic economy, researchers say

Air freight operators have increased their greenhouse gas emissions by 25% compared with 2019, analysis has found.

In 2023, air freight operators ran about 300,000 more flights than in 2019, an increase in flight volume of almost 30%. The US accounted for more than 40% of global air freight emissions, according to the report by campaign group Stand.earth.

On a journey along the Thames – where fury at pollution has spawned a wave of local activism – it is clear that the decline of rivers is among this government’s worst legacies

Red kites swoop above Fawley Meadows as Dave Wallace dips a sampling beaker into the deep green water of the River Thames on a late spring day. A sharp wind blows droplets upstream towards the arches of Henley Bridge, while the might of the river, its path here straight and wide, pulls downstream towards Windsor, on its 215-mile odyssey to the North Sea.

Today, the water meadows along its banks host blue and white striped marquees, lined up in uniform rows for the Henley regatta. After the rowers depart, the river bears the swimmers who follow. They dip, jump and dive its depths at an annual festival of open water races, echoing the galas that took place in Victorian days.

In the run-up to July's general election, the Guardian video team is touring the UK looking at the issues that matter to voters. After swimmers and rowers fell sick from sewage discharges into the River Thames we went to the seat of Henley and Thame to see how environmental concerns rank for voters in a seat that has been Conservative for more than 100 years

Light painting is a technique used in both art and science that involves taking long-exposure photographs while moving some kind of light source—a small flashlight, perhaps, or candles or glowsticks—to essentially trace an image with light. A UK collaboration of scientists and artists has combined light painting with low-cost air pollution sensors to visualize concentrations of particulate matter (PM) in select locations in India, Ethiopia, and Wales. The objective is to creatively highlight the health risks posed by air pollution, according to a new paper published in the journal Nature Communications.

“Air pollution is the leading global environmental risk factor," said co-author Francis Pope, an environmental scientist at the University of Birmingham in the UK who spearheaded the Air of the Anthropocene project with artist Robin Price. "[The project] creates spaces and places for discussions about air pollution, using art as a proxy to communicate and create dialogues about the issues associated with air pollution. By painting with light to create impactful images, we provide people with an easy-to-understand way of comparing air pollution in different contexts—making something that was largely invisible visible."

Light painting has been around since 1889, when Étienne-Jules Marey and Georges Demeny, who were investigating the use of photography as a scientific tool to study biological motion, created the first known light painting called Pathological Walk From in Front. In 1914, Frank and Lillian Mollier Gilbreth tracked the motion of manufacturing and clerical workers using light painting techniques, and in 1935, Man Ray "signed" his Space Writing series with a penlight—a private joke that wasn't discovered until 74 years later by photographer/historian Ellen Carey in 2009.
