San Joaquin lead expert gives talk to local school

As a child Tung Tran, now 62, lived with his family in a village in Vietnam at the foot of a mountain where his father worked in a lead mine.

Water from the mountain where his father worked trickled down into the village's drinking water, poisoning residents.

When Tran's 3-year-old younger brother died unexpectedly, French doctors said that he had deadly levels of lead in his body.

Tran's father eventually moved his family to a nearby city.

"That's why I stayed alive," Tran said.

Now, Tran travels the county preaching the dangers of lead poisoning in children for San Joaquin County's Public Health Services office.

An unusual number of children have unhealthy amounts of lead in their system, according to Tran.

Tran came to Joe Serna Jr. Charter School's health fair Friday morning to talk to students about lead poisoning.

China, which has come under fire in recent months for manufacturing and exporting toys that contain lead paint, has signed an agreement promising to stop using lead-tainted paint on toys exported to the United States.

In past months millions of toys manufactured in China have been recalled from U.S. store shelves.

"Hi children," Tran said Friday morning to teacher Sara Gustafson's sixth and seventh grade combination class. "Do any of you eat these candies?"

Tran holds up a plastic biohazard bag containing candies he said could be found in area ice-cream trucks.

"Yeah," the children yelled in unison. Some held out their hands for the treat.

"If you eat too much of these candies you can either lose your memory or develop learning disabilities," Tran said.

"Are you serious?," one of the shocked children yelled.

Tran said one of the reasons lead concentrations are so high, particularly in Lodi, is because people are uneducated about the types of products that contain lead.

Make up containers made in India, including a the brand "Surma," which Train said is popular with Lodi's Pakistani population, are 95 percent lead.

Also popular in Lodi are the Mexican-made candies and seasonings sometimes sold by ice-cream trucks and Hispanic markets.

However, lead can also be found in many other common household objects, such as crystals, old coloring crayons, ceramics, paint, glazes used in pottery, vinyl mini-blinds, toy soldiers and fishing weights.

Because products that have lead in them often taste sweet, Tran said, children are attracted to them.

Lead was also used to solder copper pipes in houses built before 1994, Tran said. As a result, he recommends people run their faucets at least 30 seconds in the morning before using them to wash any lead that might have settled in the pipes overnight.

People become susceptible to poisoning when they ingest or inhale lead. Upon entering the body lead usually hides out in fatty tissues, but it can eventually make its way to bones, where, Tran said, it stays permanently.

Lead can be flushed out by eating fruits and vegetables that contain calcium and iron and by eating lean meats such as skinless chicken.

High concentrations of lead in the body can cause central nervous system and kidney damage, learning disabilities and attention deficit disorder. Extremely high concentrations can cause comas, convulsions and death.

Children who are exposed to lead often don't show any symptoms, Tran said. That's why he recommends that parents who think their child might have been exposed to lead ask their doctor for a blood test.
