More than 30 percent of children's toys manufactured in Shenzhen in the past two months were found to be substandard, according to a report released by the city's quality watchdog Monday.

The report was based on a citywide inspection which covered plush toys, electronic toys and strollers, yesterday's Shenzhen Special Zone Daily said. Among the 13 batches of toys inspected, only nine batches conformed to the national standard.

Excessive amounts of metal, especially lead, were found in some electronic toys, which might pose a health hazard for children who play with the toys for a long time, the Daily report said.

Two batches of strollers were found to be potentially dangerous as the combustibility of fabrics used was not up to standard. Substandard plastic bags and film on baby walkers could also prove to be dangerous, as they posed choking hazards, officials with the municipal quality supervision bureau said.

Other problems found during the inspection were ropes so thin they could cut the skin of children, and parts that could easily be swallowed.

Experts suggested that parents pay special attention to the warning sign, validity period and operating instructions while choosing toys for their children to avoid potential safety hazards, the Daily report said.

Meanwhile, the city's quality watchdog also found in a separate inspection that nearly 30 percent of children's clothes manufactured in the city were substandard.

The screening involved 51 batches of children's clothes from 22 companies and the unsafe clothes either contained excessive amounts of heavy metal or used dyes that would run easily.

As for children's food, excessive amounts of coloring agents is still the major problem, according to yesterday's Shenzhen Evening News.
