Think before you buy toys for toddlers as even the branded plastic toys sold in the Indian market can cause asthma, lung problems and reproductive problems in children due to high toxic levels, warns a study conducted by the Centre for Science and Environment (CSE).

In its latest study released here Friday, CSE's pollution monitoring laboratory found high levels of phthalates, a chemical used to soften plastic, in all samples of toys it tested. Over 45 percent of the samples exceeded the internationally accepted safety limits for phthalates.

"We randomly purchased 24 toys from different parts of Delhi, especially those toys that children are more likely to chew and suck. Out of 24 toys, 15 were soft and nine were hard. These toys were manufactured in China (14), India (7), Taiwan (2) and Thailand(1)," said CSE Associate Director Chandra Bhushan.

"The sample included major brands like Funskool and Mattel. In our test we detected one or more phthalates in all toys. Taiwanese and Chinese toys were the most contaminated. Taiwan toys exceeded the safe limits by 100 percent. While eight out of 14 toys manufactured in China exceeded the limits," he said.

Narain said India has no regulations to control the use of phthalates in toys. "It only has voluntary standards covering safety aspects of toys. On Jan 23, the government ban on import of toys not meeting these standards will end. In the unregulated free-for-all that threatens to follow, the health of children will be compromised, putting them at a huge risk."

Bhushan said as the regulation on imports expires Jan 23, the government has two options.

"Either regulate all toys, both domestic production and imports. Second, and the easier option, let the order expire and leave the entire market unregulated, endangering the health and safety of children. As things stand now, the government does not want to make the effort to make standards mandatory for all," he added.
