London, November 6, 2017 : Love to decorate your glassware with art? Beware, the paint used can contain potentially toxic levels of lead and cadmium, increasing health risks, a study has shown.
The findings showed that in enamelled drinking glasses, flakes of paint often come off, which could be ingested over a prolonged period and prove hazardous for human health.
For the study, researchers at the University of Plymouth carried out 197 tests on 72 new- and second-hand drinking glass products, including tumblers, beer and wine glasses, and jars.
They found lead present in 139 cases and cadmium in 134, both on the surface of the glasses and, in some cases, on the rims, with concentrations of lead sometimes more than 1,000 times higher than the safe limit.
“The presence of hazardous elements in both the paint and glaze of decorated glassware has obvious implications for both human health and the environment. So it was a real surprise to find such high levels of lead and cadmium, both on the outside of the glassware and around the rim,” said Andrew Turner, lead researcher from the varsity.
“There are genuine health risks posed through ingesting such levels of the substances over a prolonged period, so this is clearly an issue that the international glassware industry needs to take action on as a matter of urgency,” Turner added.
The study, published in the journal Science of the Total Environment, analysed a range of glassware using portable x-ray fluorescence (XRF) spectrometry.
The lead concentrations ranged from about 40 to 400,000 parts per million (ppm), while quantities of cadmium ranged from about 300 to 70,000 ppm.
According to the US Office of Environmental Health Hazard Assessment, the limit levels for the externally decorated lip area of drinking glass are 200 ppm and 800 ppm, respectively.
“Given that safer alternatives are available to the industry, the overall results of this study are both surprising and concerning,” Turner said. (IANS)
Human health is paying the price of the world’s failure to curb global warming, the World Health Organization warned on Tuesday, urging governments at U.N. climate talks to cut climate-changing emissions faster and provide funds to address growing threats.
Those range from lung and heart problems caused by toxic air to deaths in storms and wildfires, and the expansion of dengue, malaria, cholera and other diseases spread by mosquitoes and contaminated water.
“The cost of not taking enough action at the climate summit … is paid by my lungs and your lungs,” said Maria Neira, director of the department of environment, climate change and health at the World Health Organization (WHO), a U.N. agency.
The causes of climate change and air pollution overlap, she added, calling for societies to “decarbonize,” including by ditching coal as a source of power and heat, and ending subsidies for the extraction and use of fossil fuels.
According to the WHO, the burning of oil, gas and coal is responsible for two-thirds of the outdoor air pollution that causes about 4 million premature deaths each year.
More intense and longer heat waves are another growing health problem in many parts of the world.
A study published in the journal Nature on Monday found extreme heat in the United States from 1969-1988 caused an increase in deliveries of babies on the day it hit and the day after, with those births happening up to two weeks before they were due.
Such early births can potentially harm children’s later development, researchers said.
At the Madrid climate talks Tuesday, activists and aid agencies cited a rise in hospital emissions linked to smoke from Australia’s recent bushfires.
In southern African countries hit by Cyclone Idai this year, they said, people are struggling to feed their families after fields and homes were destroyed.
To deal with the rising human and financial health costs of climate change, health services and related institutions need a boost in funding — currently sorely lacking, the WHO said.
On Tuesday, it released a report highlighting how countries are increasingly prioritizing dealing with climate change threats to health.
Half of about 100 nations surveyed said they had developed a national strategy or plan to tackle the risks.
Paying for improvements
But only about 38% had finances in place to even partially implement their plans, and fewer than 10% had the money to put them fully into practice, the report showed.
Diarmid Campbell-Lendrum, WHO’s coordinator for climate change and health, said all countries surveyed — from Europe to the Americas, Africa and Asia — are struggling to finance measures such as protecting hospitals from weather disasters and ramping up disease surveillance.
In richer countries, the difficulty lies in securing allocations from national budgets due to competing priorities.
Poorer nations, on the other hand, need international climate finance to help them cope, but are struggling to access it because of a lack of information, capacity and connections.
As a result, less than half a percent of international climate finance has gone to projects to head off climate risks to health, Campbell-Lendrum said.
“These countries are exposed, they are vulnerable and they are unsupported,” he added.
The WHO plans to help developing countries put together projects to bolster their health systems that can secure backing from international climate funds, he added.
One of the biggest potential sources of finance, the Green Climate Fund, has identified health and well being as a priority area but has yet to approve any projects with that focus, Campbell-Lendrum noted.
Things that could be financed might include “smart hospitals” — now being tested in the Caribbean — built to withstand strong winds and floods while also harvesting rainwater and running on solar power.
Off-grid renewable energy projects also can cut emissions from health facilities and make them more resilient in disasters when electricity networks go down, Campbell-Lendrum said.
He noted that the mental health impacts of climate change had “shot up the agenda.”
