Decorative ceramics wares in your homes may raise cancer risk

Love to decorate your homes with ceramics wares and glass painting? Beware, they may contain high levels of cadmium that can raise the risk of cancer, warns researchers.

Cadmium is commonly used to give products a bright red, orange or yellow pigment, but over time the decoration on glass can start to flake and the glaze on ceramics fail, ingestion of which can potentially raise risks to human health as well as the environment. 

The findings showed that cadmium was also found in everyday household products like second-hand plastic toys, drinking glasses, alcoholic beverage bottles. 

The surfaces of these common items were covered by cadmium more than the recommended levels which is said to be ranging from 50 to 800 parts per million (ppm).

The highest readings of up to 70,000 ppm were recorded on the enamels of old and new drinking glasses and bottles, with cadmium detected in about 70 per cent of the 197 logos, patterns, text, pictures and cartoons tested on 72 products, the researchers revealed in the paper published recently.

"If you asked most people about cadmium, they would probably know very little about it. But it is listed among the World Health Organisation's 10 chemicals of major public health concern, alongside substances such as lead and asbestos," said a Prof.

"The health risk depends on how easily the cadmium can flake off or leach out. Additional tests performed indicate that this is greatest for enamelled glassware," said the Prof.

In addition, cadmium was found in new ceramic items such as mugs, plates and bowls, with the highest recorded level of 40,000 ppm, and in old plastic products including toys, with a maximum 35,000 ppm in a decorative brooch.

Drinking orange juice could slash risk of dementia by 50 per cent

A new study now suggests that drinking a glass of orange juice every day could significantly lower one’s risk of getting dementia.

Researchers tracked almost 28,000 men for two decades to examine how their fruit and vegetable consumption affected their brain power.

Study found men who drank a small glass of orange juice were 47 per cent less likely to have difficulty remembering, following instructions or navigating familiar areas.

Lapses in memory, understanding and episodes of confusion can be early signs of brain decline which can ultimately lead to life-threatening dementia.

While there is no cure for the condition, scientists have been trying to find a cure for the memory-robbing disorder for years.

This new evidence reiterates the importance of a healthy diet in staving off the degeneration of the brain which comes with old age.

Lead study author  said long-term intake of veg, fruit and orange juice 'may be beneficial' for maintaining cognitive function.

Participants in the study answered questionnaires about what they ate every four years.

Overall, 6.6 percent of men who ate the most veg developed poor cognitive function and performed badly on the tests, compared with 7.9 percent of men who ate the least.

Fruit consumption, overall, didn't appear to influence the risk of moderate cognitive problems but drinking orange juice did, according to the research published .

Drinking glasses may contain toxic levels of lead

Enamelled drinking glasses, including beer, wine and spirit bottles, may contain potentially harmful levels of lead and cadmium, a study warned today. 

Researchers 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 limit level. 

Tests showed that flakes of paint often came away from the glass under when simulating sustained use, indicating the substances could be ingested over a prolonged period. 

"The presence of hazardous elements in both the paint and glaze of decorated glassware has obvious implications for both human health and the environment," said a researcher.

"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," he said. 

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," he said. 

More than 70 per cent of the products (52 out of 72) tested positive for lead, and the metal was found in all recorded colours, including the decorated gold leaf of some items, according to the study published. 

A similar number (51 out of 72) tested positive for cadmium, with the highest concentrations usually encountered in red enamel. 

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 parts per million (ppm), the researchers noted. 

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. 

Turner said additional analyses confirmed that hazardous elements are also used to decorate a wider range of consumer glassware that has the potential to be in contact with food. 

These include the exteriors of bottles for the storage of beer, wine or spirits, the external text and logos on egg cups, jugs and measuring cups, and the undersides of coasters and chopping boards. 

"Given that safer alternatives are available to the industry, the overall results of this study are both surprising and concerning," he said.
