Do you prefer drinking out of decorated glassware? Beware, you may be consuming large amounts of toxic lead, says new study

The presence of hazardous elements in both the paint and glaze of decorated glassware has obvious implications for both human health and the environment

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)

Exposure to Lead, Mercury Increases Cholesterol Levels

For the study, the team reviewed information from a national representative database which includes cholesterol levels and blood levels of heavy metals among US adults

Increased levels of lead and mercury in the blood could raise bad cholesterol levels, known to damage arteries, and increase the risk of heart disease and stroke, according to a preliminary research.

The findings by researchers from the Jacobi Medical Center in New York City showed that people with a high level of lead had 56 per cent greater odds of having higher total cholesterol and 22 per cent more likely to have higher bad cholesterol or lower density lipoprotein (LDL).

Those with the highest levels of mercury in their blood were 73 per cent more likely to have higher total cholesterol, while those with increased cadmium levels in the blood had a 41 per cent higher risk of cholesterol.

In addition, mercury levels increased the odds for higher LDL by 23 per cent among those who fell in the middle for their heavy metal levels, compared to those with the lowest level.

The rise in cholesterol seen with increasing heavy metal levels in the blood might have cardiovascular consequences in people exposed to heavy metals, such as in areas with disaster water crises, the researchers said.

This suggests the need for screening for heavy metals as a risk for high cholesterol and cardiovascular disease, they said.

The results will be presented at the American Heart Association’s Scientific Sessions 2018 in Chicago.

For the study, the team reviewed information from a national representative database which includes cholesterol levels and blood levels of heavy metals among US adults.

They found a notable difference between those with the least blood levels of heavy metal and those with the most, with LDL becoming progressively higher as lead levels increased. (IANS)
