Peril of the deep – the killer poison that lingers unseen in British waters
The discovery of alarming levels of PCBs, a type of chemical banned 40 years ago, has led scientists to call for an urgent clean-up
The body of Lulu the killer whale was found on jagged rocks on the Isle of Tiree in the Inner Hebrides last year. A member of the only pod found in British waters, she died after getting entangled in fishing lines.
It was a sad discovery, especially as a postmortem revealed Lulu had never had a calf. But a recent autopsy also revealed something else that is alarming marine experts and offers a bleak, damning judgment on the state of Britain’s coastal waters. Lulu’s body had some of the highest levels of a particular type of manmade chemical ever recorded – more than 100 times above the level that scientists say will have biological consequences for a species.

Scientists say more must be done to eliminate the chemicals, which have a devastating impact on marine life and can end up in the food chain
The body of Lulu the killer whale was found on jagged rocks on the Isle of Tiree in the Inner Hebrides. A member of the only pod found in British waters, she had died last year after getting entangled in fishing lines.
It was a sad discovery, especially as a post-mortem revealed Lulu had never produced a calf. But the recent autopsy also revealed something else; something that is alarming marine experts and which offers a bleak, damning judgment on the state of Britain’s coastal waters. Lulu’s body contained among the highest levels of a particular type of man-made chemicals ever recorded – more than 100 times above the level that scientists say will have biological consequences for a species.

Tewkesbury in Gloucestershire, famous for its abbey, the Wars of the Roses battle in 1471 and the floods that ravaged the town in 2007, might seem an unlikely place to look for evidence of impending drought. But stroll along the riverbank at Abbey Mill Gate and the signs are there: the mud is cracked and dry, the reeds brown and withering, and the water is starting to form pools.

South Uist The bitter leaves of this hardy little plant once provided a welcome dose of vitamin C after a hard winter
Scurvy-grass is usually found in coastal regions, where its high tolerance of saline conditions enables it to flourish where other plants fail to thrive. It is an early flowerer and will grow abundantly on steep cliffs, sometimes forming sizeable, rather untidy clumps of stemmed white flowers.
There is something endearing about this unassuming yet resilient plant, whose presence here is so linked to the beginning of a fresh new season. Strangely, its scent is not mentioned in most of the plant identification guides, yet springtime walks with a warm breeze lifting and carrying up with it the sweet fragrance of the profusion of flowers unseen on the rocky faces below have always been a delight.

Free water from the bar tap? Get the app | Letters
I can quite understand why people feel awkward asking for tap water without making a purchase (British embarrassment over asking for tap water in bars fuels plastic bottle waste – survey, 11 May). Fortunately, the Refill app from refill.org.uk will help direct people to all sorts of lovely businesses who have made clear their commitment to plastic waste reduction. They will refill with no obligation to buy anything. If there are any businesses who would like to join, they can do so within the app, and together we can provide a robust alternative to plastic drinking bottles.

Kelvin MacKenzie loses his job over “racial slurs” (Report, 10 May). Are we to infer that the nasty abuse of Ross Barkley would have been fine had his grandparents all been indigenous English or European? Is there no need to care about respecting other people and their feelings, so long as no racial or sexual orientation or religious elements lurk somewhere?

• I regularly have sparrows on the balcony of my seventh-floor Barbican flat (Patrick Barkham, Notebook, 9 May). They are from the colony which has lived in Fortune Street Park for several years. The sparrows don’t get on with the goldfinches which inhabit the estate’s wildlife garden. Alas all these birds and small mammals are prey to the resident peregrines. Who needs to live in Norfolk?

Further legal battles and protesters “standing in front of bulldozers” could be in store in Alaska, after the Trump administration on Friday settled a lawsuit over the proposed development of a massive gold and copper mine at the headwaters of one of the state’s main salmon fisheries.

He was speaking at the end of a meeting of the eight-nation Arctic Council in Alaska, a consultative body dedicated to sustaining the Arctic.

Farmers and conservationists warn of water shortage, with ‘water shunting’ from wet north to dry south seen as one solution
Farmers are warning that water may have to be transferred across Britain after an unusually dry winter and spring left more than four-fifths of rivers with too little to support local growers.
Fears of a drought were expected to ease this weekend as scattered showers usher in a more traditional British spring, but wildlife and agriculture industries are bracing for a long, parched summer.
